After the release, there will be a tag with 0.9.30. * Mantis doesn't have a Product Version of 0.9.30 to choose from. So how are we supposed to report 0.9.30 bugs? That will be possible after the release. Until 0.9.30 has been released, it won't be possible to report bugs against it.

At least I cannot find any in the dir I installed FPC into. All subfolders there are: bin demo doc examples msg units (which does not contain the sources) So no source folder. :-( What can I do now? I don't know whether this is any help and it is oriented towards Linux, but I'd add that I normally build FPC from source, in part because doing so is a good test that the compiler is working on the machine in question. Having done so I do a make install and check that the symlink in /usr/local/bin is OK, then make clean and copy the fpcsrc directory into the appropriate place in /usr/local/lib (I'm being intentionally vague here since this will vary depending on version number). Having done that, one is left with a consistent tree of binaries and source. Start Lazarus with the --pcp= option so that the IDE you're running uses a private configuration file that specifies how it can find the matching compiler. I have just downloaded the 2.4.2 source zipfile and now I have the problem of extracting it to the right location... My FPC install dir is C:\Programs\fpc\2.4.2\ Where should I put the sources? In a subdir to this named source? The zipfile expands to a top folder named fpc-2.4.2, which obviously is not my install folder name And inside there are no subdirs named source or anything like that. Advice please? The top folder (fpc-2.4.2) should contain directories like compiler, rtl, packages, etc. The best place would be to put those into your C:\Programs\fpc\2.4.2 directory and point Lazarus' FPC dir setting to that directory (then everything is where it belongs ^^). Another possibility (your choice) is to put all those directories into a source directory in C:\Programs\fpc\2.4.2 and point Lazarus to that. You are pretty free here, but Lazarus checks that rtl and packages directories exist in the set source directory.

[Lazarus] Mantis attached tags are broken
Hi, I created one report with a new tag '0.9.30', so I can easily find bug report related to the fixes_0_9_30 branch. I did a view issues and selected '0.9.30' tag as filter. It only showed one bug report. I went back to my previous bug reports and the '0.9.30' tag was removed for all but the last bug report. So it seems Mantis only allows one bug report to have one tag. That is stupid! What's the point of tags then, if you can't reused them? Usage: In each case, I selected the '0.9.30' tag from the dropdown list, and selected Attach. The tag then appeared in the 'Tags' column. But that also removed the tag from all other bug reports. :-( Regards, - Graeme - -- fpGUI Toolkit - a cross-platform GUI toolkit using Free Pascal http://fpgui.sourceforge.net/ -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

OK, I just got a Mantis report email which listed that Vincent removed all the tags - believing they are unnecessary.

So basically a widget set is a definition on what kind of graphics environment is used on the target system then? What about making a program for Linux? Do we have to compile the same program in different versions for different desktop managers on Linux? Like one for Gnome, another for KDE and yet another for X??? Sounds mighty tedious and error prone... My first project is to make an embedded application but develop it on a Windows host where I also want it to be running for checks etc. This application needs some basic graphics, like using Canvas methods to draw simple geometric forms on an image. It is similar to a graphing software visualizing acquired data as points (colored circles) connected by lines on a Cartesian coordinate system graph. Nothing fancier than that. In Delphi I created a very small graphic object TGraphImage, which has methods for scaling the canvas to real values as opposed to pixels, drawing lines, rectangles, circles etc with various simple colors. It can also print text labels on the image. I would like to use this also in Lazarus and in the embedded environment. The embedded card is a touch panel from Technologic Systems (http://www.embeddedarm.com/products/board-detail.php?product=TS-TPC-7390#), which runs an embedded version of Debian Linux, I believe.

Bo Berglund wrote: Bo, I suggest that you check that your board supports GTK etc. If it doesn't support GTK but it does have basic X graphics then fpGUI might be the least painful option. Back again so I could read up on this thread... So basically a widget set is a definition on what kind of graphics environment is used on the target system then? No, it's one or more libraries installed on the system which contain all the code to draw standard controls- buttons and so on- on the underlying graphics provided by the operating system. There is a handful of widget sets- Windows, Qt and GTK for example- and a smaller number of underlying graphics subsystems- Windows and X as examples. Note that in that case there is a part of Windows that implements a widget set, and a part that implements low-level graphics. It's possible to have the Qt widget set (and possibly others) on top of Windows's low-level graphics. What about making a program for Linux? Do we have to compile the same program in different versions for different desktop managers on Linux? Like one for Gnome, another for KDE and yet another for X??? Sounds mighty tedious and error prone... The LCL provides an interface between your program and the available widget set, all you have to do is set the project options to tell it which to use at which point Lazarus or lazbuild does the work for you. X is a red herring since it's at a lower level than a widget set. I can't speak for anybody else, but I generally compile for GTK v1, v2, Qt and Windows, depending on the underlying OS. If you set your target file name to something like myproject-$(TargetCPU)-$(TargetOS)-$(LCLWidgetType) Lazarus/lazbuild will create distinct binaries for all combinations, the only gotcha is that you need to make sure that the libraries implementing the widget set are present on the target system. My first project is to make an embedded application but develop it on a Windows host where I also want it to be running for checks etc. This application needs some basic graphics, like using Canvas methods to draw simple geometric forms on an image. No. Your first project is a simple form with one button on it that displays Hello, World! in a panel. Trust me. The embedded card is a touch panel from Technologic Systems (http://www.embeddedarm.com/products/board-detail.php?product=TS-TPC-7390#), which runs an embedded version of Debian Linux, I believe. If it supports GTK (what is that?) I've told you: it's a widget set. And I've told you what a widget set is as well :-) or not I don't know but I will ask them. You don't have to ask them. Run dpkg --get-selections |grep gtk and expect to see output something like libgpod3-nogtk install libgtk1.2 install libgtk1.2-commoninstall libgtk1.2-dev install libgtk2.0-0 install libgtk2.0-commoninstall libgtk2.0-dev install libgtkglext1install libgtkhtml2-0 install libwxgtk2.6-0 install libwxgtk2.8-0 install pinentry-gtk2 install python-gtk2 install Note the -dev packages, which contain all the development (header etc.) files. If it's a comparatively recent Debian then it will almost certainly have the GTK v2 libraries, if it's an older one it might only have v1. Lazarus currently defaults to v2 of GTK rather than v1, v1 is deprecated with limited support. If you don't have the libraries or the development packages then installing them is fairly simple. However as recently discussed that's not strictly the role of this mailing list: I'm sure that everybody in here is happy to help, but what a particular reseller is doing with an unspecified version of a standard distro is ultimately not our responsibility. -- Mark Morgan Lloyd markMLl .AT. telemetry.co .DOT. uk [Opinions above are the author's, not those of his employers or colleagues] -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus
Re: [Lazarus] What are widgets in lazarus?
Op 2011-01-05 15:23, Bo Berglund het geskryf: So basically a widget set is a definition on what kind of graphics environment is used on the target system then? Correct. As standard, Windows only has the WinAPI (GDI etc), and Delphi's VCL is a wrapper for that API. Under Linux you have more choices of GUI toolkits. Linux's GUI is provided via X11 (Xorg-XServer) and the most common library used to talk to X11 server is XLib. This all comes standard with Linux (desktop and most embedded systems). Qt, GTK, fpGUI etc are gui toolkits built on top of that, talking to Xlib (Qt and GTK also talk to Cairo, yet another graphics layer on top of Xlib). Gnome and KDE are desktop environments (the desktop you see when you boot Debian or Ubuntu into a gui mode - and their application are based on GTK2 or Qt GUI libraries respectively. LCL is another layer on top of that - a wrapper for GTK2, Qt, Win API etc... This is where LCL's bigger dependency comes from. fpGUI and MSEide talks directly to Xlib (under linux, unix etc) or Windows GDI (under Windows and WinCE). What about making a program for Linux? Do we have to compile the same program in different versions for different desktop managers on Linux? Like one for Gnome, another for KDE and yet another for X??? Sounds mighty tedious and error prone... Most linux distos for desktops (not embedded systems) come standard with the various runtime libaries. So even though you use Ubuntu and Gnome as you desktop, you can still run KDE applications under Gnome or Gnome/GTK apps under KDE. If you want improved desktop integration with the desktop environment, then it might be better to compile your apps for that specific gui library (Gnome/KDE). The embedded card is a touch panel from Technologic Systems (http://www.embeddedarm.com/products/board-detail.php?product=TS-TPC-7390#), which runs an embedded version of Debian Linux, I believe. As Henry mentioned, that website lists the core X11 server as included, and also mentions that Qt-Embedded runtime library is included. So that leaves you with an Qt-Embedded or Xlib based gui toolkits (GTK1/GTK2 was not listed, but you might be able to install that yourself). Note though that if you are creating commercial apps with Qt, you need to purchase a license (+-3500 US dollars per developer - last time I checked). fpGUI and MSEide are free, even for commercial apps. As for doing drawings, graphs etc as you mentioned - that is all possible with Qt-Embedded, fpGUI and MSEide. Just to be clear, the latter two can also be used for desktop apps, they are not limited to embedded devices.

The strong point of Qt-embedded is, that it *doesn't* use the X server but uses the framebuffer and implements an own windowing system. So you are pretty much independent from many other components. Also Qt-embedded (as does Qt) comes with lots of helper libraries (Networking etc.) that really give you a coherent framework for app development.

This should be more than enough to stream objects to and from a web-browser. I have committed an example and a testsuite. All this is in packages/fcl-json.

I'd usually expect embedded vendors to build packages specifically targeted for their processor, as there are many ARM configurations, and Debian only targets the ARMv4T architecture with no hardfloat, which wouldn't make much sense to run on more modern processors. But this specific board does have an ARM920T, so maybe they just connect to the Debian repositories.

Might you be able to post a bug report for ReactOS? I compiled and ran the fpGUI uidesigner program. The graphics didn't work right. The combobox dropdown list appeared somewhere else on the screen. The black dots around controls when you selected them didn't appear. I didn't do a lot of testing but apparently the GDI layer isn't quite done. I would guess that if you ran a Delphi or Lazarus program that used Win32 widgets they would work better. -- ___ Lazarus mailing list Lazarus@lists.lazarus.freepascal.org http://lists.lazarus.freepascal.org/mailman/listinfo/lazarus

[Lazarus] What do I need to do to install and use JEDI-SDL-v1.0
Hi All,
What do I need to do to install and use JEDI-SDL-v1.0 or which ever is latest?I
have downloaded JDL-SDLv1.0.zip and unarchived it. It is in Delphi format and
free pascal and lazarus.
See below that I have tried to run the fpc-install.sh file (with the command
sh ./fpc-install.sh ).
j...@juni ~/Public/Lazarus_source_code/JEDI-SDLv1.0/lazarus $ sh
./fpc-install.sh: not foundll.sh: 14: : not foundll.sh: 17: : not foundll.sh:
22: {^C: (that´s where it hung and I pressed control+C)
I am attaching both the fpc-install.sh and Getting Started.html. I have printed
a hard copy of the latter and it says to click on the Delphi Tools /
Environment Options menu then select the Library tab then click on the ellipsis
for Library Path. This is different in my copy of Lazarus 0.9.28.2 for Linux.
Any help will be welcome. Thanks in advance.

Title: Setting up Delphi or Kylix to work with JEDI-SDL
Setting up Delphi or Kylix to work with JEDI-SDL
Extract the JEDI-SDL Zip file or Tar.gz file, to a directory
of your choice, making sure you maintain the archives built in directory
structure. For example I have a "headers" directory under my Delphi or Kylix
installation directory. So for me on a windows machine I have installed
JEDI-SDL to. "D:\Program Files\Borland\Delphi6\Headers\JEDI-SDL\.". Make
sure you remember this path and also that under Linux, paths are case
sensitive so you may want to keep everything in lower case. The main advantage
of extracting them under your installed Delphi or Kylix directory is so
you can make use of the $(DELPHI) path directive as shown in the next few
steps
Next we need to make sure we are using the latest Runtimes for
out system. in the \JEDI-SDL\Runtimes\ directory you will find the
latest Linux ( in RPM format ) and and Windows ( DLLs ) runtimes.
Under Linux install each RPM and everything should be ready to
go on to Step 3.
NOTE : For the DeathTruckTion game to run you must have either
fmod.dll ( under Windows ) or
libfmod-3.5.so ( under Linux ) installed.
Under Linux, make sure you are logged in as root and copy the libfmod-3.5.so
file from the Runtimes/Linux/ directory to your /usr/lib/ directory. You
also need to ensure that the shared library has the correct permissions,
other wise it will not execute correctly. So via a command line, navigate
to the /usr/lib/ directory and enter the following command ( it assumed you
are in /usr/lib/ and logged in as root )...
chmod 755 libfmod-3.5.so.
Now you need to create a symbolic link between libfmod-3.5.so and libfmod.so.
This is done with the
following command ( it assumed you are in /usr/lib/ and logged in as root
)...
ln -s libfmod-3.5.so libfmod.so.
Similarly, I found that the smpeg RPM did not install smpeg correctly.
In you /usr/lib/ directory you will
Re: [Lazarus] Project conversion Delphi - FreePascal: success!
2011/1/3 Birger Jansen bir...@cnoc.nl Hi all, Last month I converted a 500.000 lines Delphi project to FreePascal, and I wanted to thank those who replied to my questions over the mailing list and the whole FPC / Lazarus team for delivering a great product. Also all contributors to wiki pages, newsgroups and forums: thanks! Even the smallest pages or postings contained useful information and are a valuable source of information. The converted application is an output viewer for calculations based on the finite element method. It is intended for 2-Dimensional and 3-Dimensional geotechnical analysis of deformation and stability of soil structures, as well as groundwater and heat flow, in geo-engineering applications such as excavation, foundations, embankments and tunnels. (so this is a result viewer, the actual calculations are performed with another application). Hi Jansen although it is no longer my main job I am geotechnical engineer and I'm curious on the finite elements application: did you do it? is it in pascal? what is his name? As for the viewer it look very professional so BRAVO! Regard Salvatore The conversion was a pilot with the main reason for trying FPC the need for 64 bit. During conversion I encountered lots of small issues (Unicode, OpenGL, images with scanline manipulation, generics, anonymous methods, class constants and functions, MDI forms, treeview with custom drawing, Steema TChart, custom controls and more). For most of the encountered issues I created a list with their solution, I'll try to clean it up and see if I can post it somewhere because it might also be helpful for others. Attached you will find some screenshots of the result, these give you an idea of what the program does.
