I am thinking along the lines of compiling "a package only". The Compile
settings
for packages don't have a "Run/Build Many Modes...". That only applies to
Projects.

I suppose that this depends on using building a project with the right

button on the package to compile for all the chosen widgetsets in one go.

They've lost the mobile
war for the next few years to come until Xamarin makes app development easy
for Windows for
developers to produce more apps for the mobile platform.

They are definitely going after Redhat, and Oracle in the short-term. They
are not going the mistake
they made with Apple.

SQL Server will be available for Linux quite soon.

They have recently announced Bash for Windows and they are aiming to get a
lot of Unix tools running easily on Windows.
In fact those tools have been there for a while but they were not seriously
promoted.

They are going after the whole Linux.Unix system. They want Linux admins and
developers to realize that they can have good GUI development and
server-management
tools available on Windows and still have all the command line goodies
they've learned to
love on Linux.

Given the lack of integrated toolsets available for Linux, they will
probably make it.

Is there some way to build a package for all widgsets in one go like the
IDE's Build Many option?

Changing widgetsets results in a recompile of a lot of GUI packages and
wonder whether that can be avoided. Adding the LCLWidget to the output path
of packages doesn't seem to work.

The only way I can think of is to have separate Lazarus builds for each
widget set which share the same --pcp option. For cross-platform I mainly
use Qt as the GTK widget set doesn't seem to work well on Windows.

The cloud is getting dominated by Linux and if Microsoft doesn't have an

[Lazarus] What option do I need to build Lazarus executable itself from a different OS or architecture?

[vfclists .]

I have managed to get FPC cross compilation from 32 bit Linux to  64bit
Linux and both 32bit and 64 bit Linux.

My next step is to generate the Lazarus executable itself for all 4
systems. My current command for building the 32 bit Linux version of
Lazarus is:


make all PP=${THIS_BUILD_COMPILER} USESVN2REVISIONINC=0  LCL_PLATFORM=gtk2
make PP=${THIS_BUILD_COMPILER} bigide


What option do I have to add to ensure that the Lazarus executable and
units are targeted to the right CPU and OS?


PS. Can Lazarus be built as an application from the IDE itself, like cross
compiling an executable for a different architecture?

If you are on Linux and you are okay with Qt you might consider the QT
webkit demo.

It will probably make things way easier for you. It might prove a nice way
to learn out to use the Qt 4.8.x series directly.

I tried the Internet Pro control first but realized that it would be more
difficult in the long term. If you are bold enough you might be able to
make it into a component.

It is available at http://users.telenet.be/Jan.Van.hijfte/qtforfpc/ file
name lclwebkit.zip

I just noticed http://sourceforge.net/projects/lazwebkit/ which is GTK2
compatible bit I haven't tried it yet..

Are most of the options the same as what is available in the IDE?

 If your Git mirror cloned all the details you need (trunk, branches and
 tags), then yes. Simply checkout the branch you want using git checkout
 -b name_of_branch. Setting up such a git mirror is quite hard though
 (dependent on how SubVersion was abused) - at least it was when I last

I am using your Git mirror :). Does it clone all the necessary details?

 Sorry, I probably haven't had enough coffee yet, but I don't fully

 a git mirror (of a subversion repo). That is exactly what the command

 As far as I understood, you are interested in finding the SVN revision
 of that commit - which is r48507 (by looking at the git-svn-id line.


 ===
 $ git svn find-rev $(git log --max-count 1 --pretty=format:%H)
 48507
 ===

 As you can see, the command returns exactly that revision for you.


 The first time you run the 'git svn find-rev' git will do some layout
 migration (svn info) for you. Maybe it is also because I'm using the
 very latest Git. But after the first run, it will always only return the
 svn revision number.


Your original answer was correct. I needed something for any commit not
just the latest, but the example I used was for just the latest commit, and
I confused myself as a result.

 Alternatively you could do something like this:

   git log -n 1 -z | grep trunk@[0-9]* 

 Tweak the regex to use lookbehind which could then trim the trunk@

   (?=trunk@)[0-9]+

This is what I have settled on in the mean time.

LAZ_SVN_REVISION=`git log  | grep -A 10 $LAZ_GIT_REVISION | grep git-svn-id
|  cut -d @ -f 2 | cut -d   -f 1`

It searches the commit log for the 10 lines after the git commit ref ,
looks for the line saying git-svn-id and gets the part after the '@' at
sign. It needs more refinement though.

 nope, only version (fpc -iV), and that's what building revision.inc in the

So the revision.inc is for Lazarus only, not FPC? I need to compile Lazarus

I am using this code to obtain the SVN revision of a git commit hash. The

git log -n 1 | head -n 7 | tail -n 1 | cut -d @ -f 2 | cut -d   -f 1

It checks for the seventh line, searches for the '@' in trunk@N and

The problem is the position the line with the trunk@N string varies. Is

[Lazarus] Does a Lazarus build include the revision of the FPC used to compile it?

[vfclists .]

In looking through the sources and the Help | About dialog in Lazarus, I
noticed that the FPC revision is not include in it, and that the
revision.inc file in the FPC source applies to fpcmake.

Is including the FPC revision part of the Lazarus build, and does FPC have
a way of telling its revision number, if it is checked out from a Git
mirror, ie using `git archive` without the metadata?

[Lazarus] Is adding all the related files to a package the way to stop units proliferating in the output directory?

[vfclists .]

I am using a library which uses a lot of it own related files and whenever
I recompile all those units are always recompiled. Is adding the other
additional files into a package the way to avoid this recompilation and the
presence of lots of unrelated ppus and object files?

 What do you mean with whenever I recompile?
 Compile (Ctrl-F9), Build (Shift-F9), Clean up and build, ...
 changing compiler options and build, ...


Mainly Quick Compile, Run and Build

They are files in the uses section of the project's units, but there are a
lot of them and are mostly exclusive dependencies of the projects main unit.

Using packages can be used to reduce recompilations.

[Lazarus] Does the Lazarus IDE check for the fpc.cfg in the default places on first run?

[vfclists .]

Does the Lazarus IDE check for the fpc.cfg in the default places on first
run?

I built a few instances of Lazarus from source, and although I set the fpc
binary to a shell script which had its own fpc.cfg passed to it via the @
parameter, they complained about the missing fpc.cfg until I copied the
fpc.cfg to ~/.fpc.cfg.

I thought the @ parameter made testing for fpc.cfg in the default locations
unnecessary.

Is the dependence of ~/.fpc.cfg a feature enforced by Lazarus itself or is
the fpc that triggers the complaint?

In short - does:

1. Lazarus test the fpc passed to it to ensure that it was built with that
fpc build?

2 Does Lazarus run the fpc with some parameters to check that the fpc.cfg
matches?

3. Does the test check for the fpc in the default locations, before testing
the one passed in the fpc.sh script?

My earlier builds were created with fpcup and I wonder if fpcup applied
some patch or used some scheme to fool the Lazarus first run into ignoring
the default fpc.cfg locations.

[Lazarus] Hooking into the IDEs save events?

[vfclists .]

During development a lot unneeded changes occur forms, especially when you
move them around or click on controls to set events etcetera.

I want to have settings which stop forms or data modules from being edited
or that abandons changes to the LFM or DFM when the project is being saved.
Another option will be the ability to specify what sort of changes are
allowed, like whether controls can change parents, whether they can be
moved within the same parent, whether they can be resized etc.

I don't know if Lazarus allows forms to be locked against changing, but a
good way would be to revert the file to its previous state if the system is
under source code control.

The idea is that before the IDE attempts to save a file, which in will be
mostly DFM or LFM file, the user is warned that the form has been locked
against changes and will stop the file from being saved. In the worst case
the file will be saved, but the VCS can revert it back to the last commit.

So in short are there some IDE events and procedures that can be hooked
into to decide whether some changes will be allowed?v

 There are CreateFirstIdentifier and CreateNextIdentifier in

Re: [Lazarus] Is there a separate mailing list for Lazarus developers?

[vfclists .]

When people ask questions like this it is because they are making
comparisons with other projects which are more open, or in the case of
Lazarus easier to follow.

I follow a few groups such as pharo-dev and squeak-dev regularly and others
such as web2py occasionally. In all instances once I log on to my email I
can quickly get a good idea of how things are moving, ie you know how
features are progressing and what bugs are being fixed.

I couldn't understand why I coudn't get an idea of developments in Lazarus*
just by following the mailing lists* and wondered if there was another
mailing list. The mailing list you are referring to is not listed at
http://lists.lazarus.freepascal.org/mailman/listinfo and it is clearly not
related to development of features as is generally understood.

The wiki only tells you about features after they have been implemented. It
doesn't give an idea of how and why they evolved the way they did. Although
they enable code displays to be better formatted once you have to follow
more than a few different wikis and forums they are less convenient. This
is an issue which has been well debated and I have no intention of raising
it here.

FWIW I have just spent over an hour exploring Mantis and it looks like the
place where a lot of Lazarus development related discussions occur.
Obviously it is a complex multiplatform system which is rather mature in
internet years and has gathered quite an amount of cruft and I can
understand why its developers prefer to focus on fixing existing issues
rather than spending/wasting time debating new features.

@Matthias and Bart - I think it helps to open up the more technical
discussions to outside viewing. There is always smart lurker out there who
can help with some abstruse issue which escapes you or you don't have the
time or resources for. Kostas issue is an example of what I am taking
about. Not that many people would be familiar with that area, be involved
with it and to recognize that there was a bug there let alone have
knowledge of the library or API internals to fix it. Bugs for most people
mean bugs in programming logic not in interfaces to specialized libraries.

@Juha - Perhaps you could follow the example of the older wiser heads such
as Florian and Matthias who have responded to this thread with examples and
suggestions because they had a better understanding of why I asked this
question. Just because someone's manners or style rubs you the wrong way
doesn't mean they are trolling - which is generally understood to be
creating drama and controversy for its own sake.


A belated Happy New Year to Lazarus Developers and Congratulations for what
is a good development tool given their resource constraints. ( I tend to be
stingy with praise!!)

I just read the wiki and noticed the --noconfirm option. Although I have a
list of fpcup options in my blog I missed it among the large number of
options.

IMHO the 'fpcup --verbose --noconfirm  fpcverbose.txt' method  should be
recommended as the first thing to do if fpcup fails and placed at the top
of the Troubleshooting Section in the wiki.

A full compilation takes about 20 minutes on my system and it is much
easier on the eye this way.

 Considering the svn log, squeak developed (80 commits in 2013) approx.
 50 times (!) slower than lazarus (almost 4000 commits in 2013) so no
 wonder you cannot follow lazarus comparable easily.



Squeak is a Smalltalk system and all the changes are versioned
automatically in the live image and shared via the Monticello repository.
If they use svn it is probably some ancillary systems related to the
project. Between 1st and 5 Jan their repository system has recorded 25
commits to about 10 different packages.

Anyway I am not comparing a dynamic, interpreted system using a live image
with a static compiled language as they are quite different paradigms and
the development styles are quite different.

Use 'fpcup --verbose --noconfirm  fpcverbose.txt' and view the output in a

[Lazarus] What are the prerequisites for compiling Lazarus on a KDE based system?

[vfclists .]

What are the known prerequisites for installing Lazarus on a KDE based
system?

I am able to build Lazarus using fpcup on existing Ubuntu 12.04 systems
running KDE, but I am unable to get it working on a newly installed system
so I suspect that some of the required libraries have not been installed on
the new system.

Is there a clearly specified list of prerequisites for compiling Lazarus on
Debian/Ubuntu with KDE?

 I believe this is a misunderstanding or maybe hopeful thinking from your
 side.
 The discussion is about technical details of some piece of code,
 release schedules and maybe organizing transportation for a meeting.
 You would be bored.

 There is no secret agenda about the future of Lazarus that its
 developers try to hide from you.
 The development process is as open as it gets.
 The missing features are well known: Project groups, Android and other
 targets, docking, installing packages from a repository, Unicode, etc
 ...
 The Mantis bug tracker has loads of feature requests, too.
 Everybody agrees those features are needed but somebody actually has
 to do them. Just talking and writing about them would be useless.

  Is it possible to view their archives or have some kind of read only

 No.
 Besides, I think your time is better used if you learn the Lazarus
 code base and then provide patches.
 And, if you still really REALLY want to read the developers mailing
 list, you must provide so many quality patches that you finally get a
 commit access and get invited to the list.
 I can recommend this route.

I have always had this nagging feeling that something wasn't quite right
about Lazarus and this explains it. I have been using Lazarus on and off
for about 4 years now. From the start I don't think I used more the 10% of
what Lazarus offered and in the succeeding 4 years my usage of its features
increased by 10%.

The additional features that I can think of are using the Object Tree to
navigate the components, changing the parent to move objects around, using
Control-Shift-Down Arrow to jump to the definition and Control Click with
the mouse to jump to the definition of a procedure or a type, but I suspect
that there have been more improvements since then.

I think the developers fear that if they open up the list even for viewing
alone there will be lots of acrimonious debates and disagreements with non
developers over how Lazarus should evolve, such as the everlasting Unicode
debates, and also criticism about its internal operation.

It may be a well founded fear as seen in other open source projects but it
ought to be reconsidered, with the understanding that whatever things
non-developers/participants disagree with should be raised politely and in
a tempered manner that doesn't offend or dishearten existing developers.

As for being able to participate by submitting patches or fixing bugs first
many users may consider such things outside their field of competence, or
may only be  interested in areas that affect them directly or are deeply
knowledgeable about, such the issue with transparency that Kostas recently
submitted a patch for. For me it was always a non-starter because compiles
were breaking due to missing units and I was always afraid of breaking my
installations to try new things even for my own use. It is only now that I
am becoming more confident and even then I am still wary.

I think for testing stock VM images should be used so that contributors can
just load, test and report their findings without the fear of messing up
their working installations. Testing is one area that can result in more
participants if involves just being click monkeys.

I think that opening the list may allow people who are highly skilled in
specialized areas to see where they can contribute and offer their help.
Going through Bugzilla to select bugs for fixing is okay for young
developers or students who want to cut their teeth or find a way to enhance
their skills and acquire some experience, but some of us are too long in
the tooth for that. I also suspect that some of those bugs wouldn't creep
into the code in the first place if the development process was open enough
for more eyes to spot them in the first place.

There a lot of projects which are more open but I suspect that using
dynamic languages helps with rapid iterations and enable to them to manage
debates and issues without slowing development, whereas a compiled language
doesn't afford that time and flexibility.

I think being able to see what is coming and follow their development will
encourage more participants and more bug fixing as well.

In any case if Lazarus developers feel that this approach has proved to be
the best over the years then they are entitled to continue as is.

I think the problem is more of an issue of newcomers confidence that they
can dive into the codebase and start tackling stuff, or at least they can
find someone to guide them if they want to. Systems programming is not an
easy area to get involved with and there are many developers who have never
had to get anywhere close to that kind of programming. It all looks rather
daunting for those who may not be so proficient at Pascal or experienced in
low level programming

I am already following that thread. What I have in mind is using
Lazarus/FreePascal forms as purely presentation layer, not for Pascal
programs alone, but any language, DWScript, Python, bash, Basic, whatever
even DWScript In effect the form opens a web server or another type socket
where the business layer sends the screen drawing commands to. Whereas a
browser is pull system, this is a both pull and push

When I did some Googling, knockout.js a framework that came up, something
similar for Lazarus is what I have in mind. FreePascal, LCL, fpGUI etc are
the system I know and the best foundation for a  high performance cross
platform presentation layer that I can think of.

I think parsing QML or a reasonable subset for building Lazarus UIs as an
alternative to .lfm and .dfm files is where the future of the
Lazarus/FreePascal lies. I wouldn't say the future, but it is area where
the Pascal development ecosystem can experience a revival. It is rapidly
loosing ground to programming languages  which can be are interpreted,
JITed, compiled, and have garbage collection, not just in usage, but in
performance as well.

[vfclists .]

Are there some industry standards for specifying GUIs in JSON?

Something which can specify the type of elements like edit controls,
buttons, the positions etc, and draw stuff like squares, triangles, boxes
etc? It doesn't have to be an official standard, but have widespread use to
make it easier to work with?

QML appears to be one, are there any others?

FWIW I am trying to use the LCL Widgets as a means of displaying
information from interpreter based development, passing the GUI creation
commands over a socket.

  Hello Michael,

  Why not use an existing webkit (like Qt or Chrome) and incorporate it
 into Lazarus? That would leave the responsibility for compatibility with
 HTML5, CSS3, mp3 encode, webGL, file manipulation, , support for
 cross-platform etc. for the webkit.

  Please see this nice project:

  https://github.com/rogerwang/node-webkit



 What would it take - in the form of a bounty - to get a community wide
 project to get Lazarus a *real* HTML5 browser for OSX and Linux?  I assume
 windows is already just an Active-X component.

 Any ideas? I can't stress this enough that it's like living in the
 technical dark-ages without access to developing front-ends without rich
 text and more often for me  now, web apps.



I think I mentioned what your real problem was in the my previous response.

Most of  we want can be found in
http://www.elevatesoft.com/products?category=ewbtype=web. The developer
speaks of Linux version being in the works which could be because the
backend probably depends on Delphi. Delphi as usual continues to be Lazarus
and FreePascal's worse enemy.

My  own feeling is that getting the Lazarus form builder to generate Pascal
code rather than, or as well as the .lfm files  is the first step. Then
Javascript next, QML or whatever. The Delphi legacy is still hanging over
Lazarus. Phil Hess did something that could translate a subset of the
components in.lfm files into Javascript some years ago and that may be a
start.

  And I am not really looking forward to writing InstallShield from

You haven't stated whether your program is for Windows or Linux but I am
assuming that it is a Windows program.

http://www.enterprisedb.com/products-services-training/pgbindownloadprovides
binary installations of PostgreSQL. I haven't tried them yet but I
believe they enable you to run PostgreSQL outside the standard
installation, ie embeddeding them separately for your own programs.

PostgreSQL enables you to run the postgres executable using different
settings, ie different data directories, different port, authentication
etc. If there are preinstalled executables you can use them to run against
your own dedicated cluster and even configure it as a service.

 Hi all

 I have used Lazarus with PostgreSQL in a client-server setup before.
 It worked very well when I installed it at a client.

 I have also written desktop Delphi programs using Paradox as database
 and InstallShield as the installer before, which worked very well for
 distributing programs on CD (or DVD). What would be the best Lazarus
 equivalent for this purpose? I.e. a program with a pre-existing,
 populated database that can be distributed on (and installed from) a
 CD or DVD by users.

 If I use PostgreSQL it would need to see if the Postgres RDMS has
 already been installed on the desktop, install it if not, populate the
 PostgreSQL database with the data on the CD and install the program
 itself (with possibly adding a shortcut depending on the window
 manager used). I have never studied .deb (much less) .rpm packages in
 detail, so I am not sure if all of this functionality can be packed in
 there. And I am not really looking forward to writing InstallShield
 from scratch for Windows if there is a better alternative.

 Any ideas?

There is nothing particularly wrong with MySQL. Together with its partner
in crime PHP they were hacks their developers put together to make things
easy for their developers and they caught on quickly in the early days of
the web. They just outgrew their intended usage (good enough) and once
their installed base grew it became difficult and expensive to enforce
compliance without breaking existing applications.
When you know that MySQL was developed from an even earlier toy database
called msql you will understand.

Just Google some of the debates surrounding them in their early days when
Monty Widenius or( was it David  Axmark) said something like ACID
compliance was not necessary in an RDBMS or MySQL was ACID compliant or
some other such tripe to understand why MySQL is the way it is. At that
time PostgreSQL was at the 6.5 or so level and MySQL ran rings round it in
ease of installability and performance. You just  had to copy the files
from one place to another and off you went. Try doing that with PostgreSQL.
MySQL also worked very well with Windows which was a bonus. It just
couldn't be beaten for ease of deployment.

Consider that most of the other database cost a bomb in licensing and you
can see why MySQL became so popular. It was such a doddle to use. Compare
MySQL's command line tools to those of PostgreSQL or Firebird's command
line tools and you will see why MySQL became so popular. Did I mention the
licensing issue?

This attitude which exists in the Pascal community needs to end. I say
Pascal not FreePascal because when I examine a lot of free Delphi libraries
I see the same thing. Lots and lots of code and not a comment in sight. It
makes stuff needlessly difficult. The simple fact is documentation is never
going to happen because no one has time to create it with separate tools,
not even the people writing the code themselves. Coding time is the best
time for documentation because that is when the intent of the code is clear
and fresh in the developers mind, and incurs minimal additional cost. After
all it takes barely a minute or two to describe a function, and the same
parsing tools compiling the code can pull out the comments and create
documentation stubs if there is a need to flesh them out further, eg with
examples etc

Even a lot of the funded open source libraries don't have the resources to
create proper documentation. If you take Delphi for instance, since Turbo
Pascal, Delphi 7 etc the quality of documentation has gone down and these
are companies that are well funded.

Instead of doing the simple thing a purist attitude has been adopted which
never does anyone any good.

It is time developers learn to treat other developers as consumers not
people who are supposed to RTFC or RTFM. Developers are people who are
supposed to put parts together just by examining the function parameters
and the function descriptions rather than wade through loads of procedure
definitions and sample code full of similar sounding and confusing names.

Enough digression - if considered carefully a comment about the purpose of
an object belongs in the object definition itself. Why should interrogation
about an object's purpose be handled by a whole subsystem of code which has
precisely nothing to do with the object, ie the operating system, a help
displaying program, a filename which is the help document, as well as a
search string which is the object's name? Multiply that by the variety of
help displaying programs for each operating system, then by the number of
operating systems available then you can see how ridiculous the whole
concept is. Just bureaucracy piled on bureaucracy and attachment to ill
thought out convention and tradition. There is never a direct link between
an object and the  help display programs available on the operating system.

There is a totally insane disconnect here. The Smalltalk guys got it right.

There can be an options to strip the comments out in the final deliverable
just like the debugging information.

 No IMHO, that would complicate reading the code (more cluttered) as you can
 see in the newer Delphi versions (called attributes instead of annotations
 though).



This is what folding editors exist for. The developer can fold them out of
view when he doesn't need to read them This facility already exists in the
Lazarus editor.

Any way I thinking of simple one liners, not whole paragraphs.

[Lazarus] Should TObject or TComponent have a Comment property?

Should TObject or TComponent have a Comment property?

I think they should. One for the design itself and one for describing the
usage at design or runtime.

Smalltalk has it.

Consider it a version of the Hint property but for the developer

Re: [Lazarus] [OT] New Lazarus website

[vfclists .]

I think Delphi compatibility is given too much prominence in the basic
description. Lazarus is first and foremost an Object Pascal programming IDE
whereas Delphi compatibility is RAD/GUI via components aspect. I don't
think 18 years after Delphi was introduced many Windows users know what
Delphi is, let alone MAC or Linux users.

It should be introduced as an Object Pascal crossplatform development tool
that should be seen as a good alternative to the basically C++, Objective-C
and Python development tools on the non Windows platforms that also give
access to Windows.

Object Pascal as an alternative to C++, C, Python requires better emphasis.

The note on this page
http://haiku-os-dev.blogspot.co.uk/2013/06/clipnote-handy-app-for-haiku-done-in.htmlstates
that the size of the app will be 20MB upwards. Is that due to the
library size or does it contain debugging information?Did the author of the
program use the appropriate compile options?

The 'strip' utility should also be able to strip out the debug information
if that is the cause of the bloat.

 No. Default is ''.

 Mattias


Is there function in the LCL that can suggest or create a name for new
component, like in the IDE that creates a name from the component type and
an integer?

 We can wait some time to see what's happening... ;)

 Salut!

My advice is to document what you do as well as you can, so that others can
use the information to contribute it back to the main Lazarus project.

FWIW I think Lazarus IDE development could do with a shot in the arm.

Why don't they give make it a 120 or 180 day evaluation with bug fixes
included? It takes time to evaluate a product as well as develop a good
product in it, something you may be doing in your spare time. If after
using that long it turns out to be good enough the purchasing decision is
simple. They seem to forget that the cost in time of evaluating a product
is way higher than the cost of the product itself.
