You must have a nonstandard system somehow ?

with T.Dependencies do
  begin
  AddUnit('sqldb');
  AddUnit('fpdatadict');
  AddUnit('fpddsqldb');
  AddUnit('mssqlconn');
end;

Unless there is a compiler error, DatadictOSes*MSSQLOSes should not 
contain WinCE, since wince is not in

MSSQLOSes, hence fpddmssql.pp must not be compiled at all ?
As your fix (commit 32843) shows, the inclusion stems from the following 
line where DatadictOSes is not intersected with MSSQLOSes

[Lazarus] ScrollBox - How to get proper scrolling for a TPanel?

[Gabor Boros]

Hi All,

I have a TScrollBox (Height=150) and a TPanel (Height=450) in it.
With Linux-Qt I can scroll up and down if the mouse over the scrollbar, 
the empty space or the Panel in 13 steps.
With Windows can scroll if over the scrollbar or the empty space (in 13 
steps too). But the scroll not working if mouse over the Panel. I can 
override DoMouseWheel but down know how to get the 13 steps long 
scrolling from it. Any idea? (I use latest fixes_1_6.)

IIRC even "Lazarus" name was discussed at some point as having religious

Which is kind-of is... but to avoid another Phoenix bird named project.

[Vojtěch Čihák]

Hi,
 
I just tested and PaintSwastika always paints clockwise swastika (both 
religious and nazi symbol).
I vote for keeping procedure but there should be added boolean parameter + 
patch for painting anti-clockwise swastika (which is religious symbol only).

Additionally to Micheals answer:

Please don't be foolish. Would you want to dispel any star symbol
because the soviet union, satanists and northern korea use(d) a red

One could demand to remove any religious reference, then the name would

censorship that is.

While I agree a similar argument can be made for anything that offends
people there are some differences here.

First f all. Taking offence against a  cross (because of religious
beleives) is not of the same order as taking offence against the
symbol of the Nazi's.
While I am willing to defend each and everyone's freedom of speech,
IMO this does not imply that we (the Lazarus community) should
actively support speading such logo's.
(Nor should we e.g. support bashing of any religion/race etc in our
sourcecode or comments.)

As for the "its an ancient rune" argument: the same thing can be said
for several phrases that now are considered to be offending to e.g.
ethnic groups, and we do not promote these her as well.
Current state is that the Swastika now has very strong associations
witj the Nazi regime and all the evil it stood for.

So, yes, IMVPAPO, it should be removed.

NB. The function was apparently introduced by Seppo (over 9 years ago)

[Lazarus] Installation under SUSE

[Josef Schnieder]

Hello,

the setup-script from http://www.getlazarus.org/setup/ will not work 
under SUSE (open SUSE 42.1 Leap).

the message is:
"This script requires the package libgdk-pixbuf2.0-dev which was not 
found on your system"


But I can't find this package for SUSE.

What should I do?
Is there another way to install Lazarus with FPC 3.0 under SUSE.

best regards

Re: [Lazarus] Do we really need a PaintSwastika procedure?

[Anthony Walter]

There are many versions of the religious swastika symbol, but is only one
version of the swastika is draw with the squared capped leaves and a stroke
width exactly equal to 1/5th of the linear diameter. Guess which one the
lcl function draws?

http://cache.getlazarus.org/images/nazi_symbol.png

And I've looked at the unicode characters. They don't draw the Nazi
swastika, the stroke width and end caps aren't the same, but our lcl
version precisely matches the Nazi version.

Hi,
 
I guess you can't run Lazarus without this package.
Maybe you need to add some repository, but I have no openSUSE anymore.
Anyway, the package exits:

Try to find a way to install it via YAST rather than install *.rpm directly.

I'm inclined to agree, particularly since the variant that has such 
unpleasant connotations was usually drawn at a 45 deg angle while almost 
all other renditions are square (i.e. all elements are either horizontal 
or vertical).


There's a general principle that numbers can't be copyrighted or 
patented, and that extends to various "illegal numbers" which some trade 
bodies and even a few jurisdictions insist can't be published and 
shouldn't even be read outside certain narrows contexts. I think this 
principle should also extend to simple geometric shapes.


So come on chaps. It's not as though we're talking about something 
completely unambiguous like the Waiblingen triple-headed eagle or even

Dmitry, you have full SVN write access, don't you? You can commit it
without any bug reports.
There could be more variations. Swastika has been drawn standing on
its side, clockwise and counter-clockwise, and standing on its corner.

It has a very long and rich history. It is a nice looking symbol and
for that reason has been so popular during the millenniums.
It is used in Russian Orthodox religion and many other religions
especially in Asia. It has been used in Finnish traditions and art
always. It was a symbol of many military air-forces including Finnish
air-force from its beginning.
And so on ...

I was actually awaiting for someone's else approval to commit :) (r51215)
As for "corner standing" there's already RadAngle parameter.

Imho, the reason the procedure is there it's because it's quite easy to be
drawn.
(Specifically using Polygon method).
ExtGraphics doesn't really have any other religions/cultural symbols there.

This discussion is ridiculous! With thinking like that even the project
name "Lazarus" can't be used. Get real people!

When I look at that, I see a "running stick figure", or a Ninja throwing

to what mentality you have.

Well what about "PaintCross", "PaintFivePointStar",
"PaintFivePointLineStar", "PaintChevron"? 

All in the same unit ... has anyone ever used that procedures, what do
the results actually look like?

I'd be with you and support that idea if any star symbol having a
satanistic or stalinistic look would be removed, too.

Go ahead, burn the witch, what's next?

Ehm... You do know that the one with the tip at the top is *not* a satanic

standing on its tip. I should know, because I like to wear the protective
variant ;)

Re: [Lazarus] ScrollBox - How to get proper scrolling for a TPanel?

You can use a own inherited TPanel and override its WndProc to send the

uses  Classes, ExtCtrls, LMessages, Forms, Controls;

type
  TMyPanel = class(TPanel)
procedure WndProc(var TheMessage: TLMessage); override;

What should I do?
Is there another way to install Lazarus with FPC 3.0 under SUSE.

FWIW,

The Education repo of Opensuse has lazarus 1.4.4

The "Hakenkreuz" wasn't black on white surrounded by red everywhere.
Especially on sculptures (think eagle of the Reich) it was more often than
not simply the base material with the "white" being air.

Anyway, I agree that PaintSwastika doesn't necessarily have to do with the
Nazis...

Re: [Lazarus] Installation under SUSE

[Gordon Findlay]

Suse Leap (I no longer have and OpenSuse 13 machines) seems to call the
required packages

gtk2-devel
cairo-devel
pango-devel
gdk-pixbuf-devel
atk-devel
ghc-X11-devel

Most likely install commands such as

  zypper install gtk2-devel

would be fine, but much depends on the way repositories set up. On this
machine there are (too) many repositories, and much more time is spent
updating metadata rather than installing.

To test for a package being installed I always use rpm, in a naive way:

rpm -qa | grep gtk2-devel

which is slower than it needs to be, but installing Lazarus is not done
very often.

Incidentally I ran the script from getlazarus.org on two Leap installations
a few days ago. The first one went swimmingly; the second one failed as the
make of lazbuild failed. I never located quite what was the problem: to
save time I just copied the installation that worked.

Ok, I've learned sth. today. But this thread is about what (anxious)

other reasons. ;)

Maybe this discussion can be closed when the names are mangled for

That's the point :) It's FivePointLineStart, not Pentagram. (

It might look the same, but in the end it's FivePointLineStart.

r51217 introduced LineWidth parameter (which should probably be renamed to
LeafWidth) that allows to specify a different than default 1/5th diameter.

That also brings the memory of my childhood. Unfortunately I was about 2-3
years old that the event the occurred, so I could not be a witness myself,
but...
But a couple of older kids (4-6 years) were left at home for a short period
of time (less than an hour or so). However, after a few minutes of playing,
they got really scared that the nazis might come in. Being terrified of
being captured they took all black markers, pens and pencils they could
find at home and started drawing swastikas all over the house. (I cannot
confirm if they were the right 1/5th proportion). But in a few minutes all
walls in were covered in swastikas.

Despite their hopes and worries, instead of Nazis, parents appeared! They
were really mad about what has happened and caused kids to do some labor
and cleaning up the mess.

The inconsistencies of Linux distros are mind boggling. SUSE probably
named the packages something different. So use its package manager and
search for keywords like "libgdk", "pixbuf", "gdk_pixbuf-2.0",
"gtk-x11-2.0" etc until you find a package similar to
libgdk-pixbuf2.0-dev, install that and see how it goes.

Alternatively, you can also compile Lazarus + LCL with the LCL-qt4
widgetset, instead of LCL-gtk2 widgetset.

Regarding a patch, can whomever creates/applies it insure the PaintSwastika
procedure does not default to the Nazi symbol characteristics?

That is don't default the leaf widths to 1/5th the linear width (The Nazi
version is the only swastika with those proportions. Please don't default
to the Nazi proportions). Also most religious versions either use counter
clockwise leaves or rounded end caps. I'd go with defaulting the leaf
direction to counter clockwise as almost all versions other than the Nazi
one default to that direction.

It's easy, just changing  LineWidth: Single = 0.20 to whatever
But how about backwards compatibility?
I doubt anyone is using the function, but introducing an incompatibility
requires at least documenting it.
As you know there're far more important notes to be done for the coming
Lazarus release.

Besides, Nazi's swastika should be turned by 45 degrees. The procedure is
using 0 degrees by default.
As Graeme pointed out colors don't match either.

In the end. It's not about a routine. It's about how an end user

Re: [Lazarus] Installation under SUSE

[Anthony Walter]

Josef, I am the maintainer of http://www.getlazarus.org.

Unfortunately each Linux distribution can use different package names for
their distribution when compared to other distributions (eg. Redhat,
Debian, Suse). There is no Linux standard for either a universal package
management system or universal package names.

What we users are generally left with is either to depend on the
distribution manager to put the software we want into their own proprietary
package management system, where the software versions may potentially lag
far behind.

OR

We can attempt to build software from sources where we typically execute
run a configure script to check for the existence of binaries and then we
have to use our knowledge to locate the package for our distribution to
install the missing requirements ourselves.

The Linux install script at http://www.getlazarus.org/setup/#linux is a
compromise. It it build mainly around Debian but will attempt to find
certain programs or libraries if you distribution supports it, and at least
tells you the names of packages it's looking for if their binary parts
cannot be found, but realistically it's going to fail most of the time when
your not using a Debian based distro (Debian, Raspbian, Mint, Ubuntu).

What's really needed is a list of all the various distros, their package
manager names and arguments, and the names of their equivalent packages.
This would require me or a group of people to examine each distro and
figure out the differences, then merge the result into a single script. Me
personally installing all the different distributions (possibly using a
virtual machine) and mapping out all these differences is not something I
want to commit time to (and it would take a significant amount of time).

If you want to figure out the package names for Suse, and research the
package manager check for install and package manager install programs plus
arguments, along with the names of the packages required to run lazarus,
you can send that info to me at ad...@getlazarus.org and I can include it
within the Linux install script if Suse is detected as the current
distribution.

[Lazarus] [Possible BUG] Incompatible ppu

[Tomáš Emresz]

Hello,

have  an  problem with detection of ppu compatibility. I'l describe my
steps (shorted):

1) install fpcup
2) install fpc fixes_3_0_0
3) instal lazarus fixes_1_6
4) open package (postgresdac, with lot of changes)
5) at now, it was compiled ok
6) install this package
7) rebuild lazarus
8) open simple commandline apps, add one unist from package to uses
9) compile
10)  app_server.lpr(13,3)  Fatal:  Cannot find PSQLDirectQuery used by
app_server, incompatible ppu=C:\\i386-win32\PSQLDirectQuery.ppu, 
multiple packages: dclPostgresDACL, PostgresDACL

This  file is on disc at this place. When i delete them, recompile the
package, the new one shows.

So it seemslike bug i think.

Sorry  -  i'm  totally   new  to  lazarus  (moved from delphi and code
typhon).

I  tried  run  lazarus  from debugger (for debug compile process), but
this way have a lot of error, which i didn't understand this time (new
in lazarus).

For the sake of completeness we also shouldn't forget about
