The Lazarus team is happy to announce that Lazarus 0.9.30.4RC2 is available for download from:
http://sourceforge.net/projects/lazarus/files/

Choose your CPU / OS / distro and then the 0.9.30.4RC2 directory.

The Lazarus testing repository at
http://www.hu.freepascal.org/lazarus/dists/lazarus-testing/ has been updated too.

This release candidate has been build with fpc 2.6.0 (0.9.30.2 was built with fpc 2.4.4).

Compared with 0.9.30.4RC1 the following changes have been made:
* configuration error in the windows installer has been fixed
* problems with threading under gtk2 has been fixed
* several bug fixes for the gtk2 and qt widget set interface have been merged from trunk

Please, let me know if you find any problems with these release candidates.

Also let me know if you installed it without any problem.

What's that from SVN? Some of the naming's beginning to look a bit ragged.

Not tried other platforms yet.

AFAIK no developer has a Sparc machine to test.

The patches users sent for Sparc were for 0.9.31 and were all applied. Does 0.9.31 run on Sparc?

Mattias

There has been one available here for years, Vincent has used it in the past. However at the moment I'm a little suspicious of it- might have suspect RAM.

The patches users sent for Sparc were for 0.9.31 and were all applied. Does 0.9.31 run on Sparc?

It did until recently ** , I'll check again.

** Except for a problem that I raised a few weeks ago, where some forms were being mis-read. But that appeared to affect all platforms, and I had to back out due to pressure of other work.

And did 0.9.30.2 run on it? If it does, then I will try to fix it for 0.9.30.4 too.

Vincent

I think so, I'm working on it (although I've got other problems here that might force me off).

0.9.31 at 35613 using 2.7.1 doesn't exhibit this problem, but it is unable to display some project forms (on any platform) for reasons which are yet to be resolved (I think I got as far as determining that it was specific to GTK2).

0.9.31 at 35818 using 2.7.1 is OK apart from the form problem.

0.9.30.4RC1 built from /tags/lazarus_0_9_30_4RC1 using 2.6.0 has the problem.

Which versions do you want me to try next?

het volgende geschreven:

0.9.30.2 built from /tags/lazarus_0_9_30_2 using 2.4,4 or 2.6.0 (2.6.0 probably won't work)

Vincent

I have just fixed another TAChart bug which is present in 0.9.30.2: http://wiki.lazarus.freepascal.org/Lazarus_0.9.30_fixes_branch#TAChart_3

It is a rare condition, but encountered by at least one user and may cause Lazarus crash at design time:
http://forum.lazarus.freepascal.org/index.php/topic,16195.msg87774.html#msg87774

So if, by chance, you will end up issuing another RC, please merge this. Otherwise, do not bother -- said user is on trunk anyway ;-)

C&P from my build scripts to try to keep tab on what's happening. This one still fails:

LAZTAG=/tags/lazarus_0_9_30_2
USEFPC=2.6.0

Reverting to 2.4.4:

LAZTAG=/tags/lazarus_0_9_30_2
USEFPC=2.4.4

Also fails. I can say with a fair degree of confidence that 0.9.30 and 0.9.30.1 (both on 2.4.4 with GTK2) are OK, but I moved off them towards trunk because of code generator problems, and haven't recently exercised them very hard on SPARC due to form-reading issues that rather got overshadowed by other work.

Next tags/releases to test?

Op 8 maart 2012 19:19 heeft Mark Morgan Lloyd
het volgende geschreven:

No, thanks.

Looking at your test results, I don't consider this issue in 0.9.30.4RC2 a regression compared to 0.9.30.2 and it will be fixed in the next release from trunk.

Vincent

Whatever, I've got it: Ludo's patches (specifically align_all.diff) from issue 19109 haven't been applied. This will also affect at least some ARM variants.

Op 8 maart 2012 19:19 heeft Mark Morgan Lloyd

I merged the revisions from issue 19109.
Please try:
fpc 2.6.0 and /branches/fixes_0_9_30

Vincent

LAZTAG=/branches/fixes_0_9_30
USEFPC=2.6.0

Works like a charm :-)

That should be OK on SPARC Linux and Solaris, and ARM Linux. Apologies that I was getting panicky yesterday, but I was seeing things go wrong that I'd had running before, but forgot that in at least some of those cases I'd been habitually applying the patch manually.

2012/3/7 Vincent Snijders :

Hi,

I'm using Lazarus (at moment three version of Lazarus, for test) and FPC from SVN, I have an issue with specialization (in a GLScene unit).

FPC svn:
http://svn.freepascal.org/svn/fpc/tags/release_2_6_0/

Lazarus:
http://svn.freepascal.org/svn/lazarus/branches/release_0_9_30_4/ http://svn.freepascal.org/svn/lazarus/trunk/
http://svn.freepascal.org/svn/lazarus/branches/fixes_0_9_30/

So, with Lazaru 0.9.31 (trunk) no problems, all works very well. Instead, Lazarus 0.9.30.3 or 0.9.30.4RC2 can't compile this code on GLScene:

{$IFDEF GLS_SERVICE_CONTEXT}
  TServiceContextTaskList = {$IFDEF GLS_GENERIC_PREFIX} specialize {$ENDIF}
    GThreadList < TServiceContextTask > ;
{$ENDIF GLS_SERVICE_CONTEXT}

I read that FPC 2.6.0 doesn't need anymore "specialize" keyword, so removing it it can compile, but when I use "code completion" (ctrl+space) in my code I get this error;

Free Pascal Compiler version 2.6.0 [2012/03/09] for i386 Copyright (c) 1993-2011 by Florian Klaempfl and others Target OS: Win32 for i386

Reassuming:

With "specialize", both 0.9.30.3 or 0.9.30.4RC2 don't compile, but ctrl+space works
Without "specialize", both 0.9.30.3 or 0.9.30.4RC2 compile, but ctrl+space doesn't work.

With or without "specialize" 0.9.31 compile and ctrl+space works.

Ok, clear. You cannot use the release and must use the trunk version.

Hi,

The problem is because GLScene wrongly define GLS_GENERIC_PREFIX depending on LCL_RELEASE instead of FPC_RELEASE.

I submitted a patch for that a few time ago and it is now available in the GLScene trunk.
http://glscene.svn.sourceforge.net/viewvc/glscene?view=revision&revision=6008

{$IFDEF GLS_SERVICE_CONTEXT} ?TServiceContextTaskList = {$IFDEF GLS_GENERIC_PREFIX} specialize {$ENDIF} ? ?GThreadList < TServiceContextTask > ; {$ENDIF GLS_SERVICE_CONTEXT}

2012/3/9 Patrick Chevalley :

Thank you!
Anyway, I update everyday sources from svn (lazarus, fpc, glscene) and I'm using r6018 of GLScene, but the problem is still present.

Kjow

What FPC mode is GLScene compiled with? The need for "specialize" and "generic" depends on the mode (mode Delphi does not allow them, while the other modes need them).

Regards,
Sven

GLScene use Delphi mode, so if I understand, it never need the "generic" prefix? In this case I don't understand why this ifdef to include it in the GLScene source. Do an older FPC version need it also for Delphi mode?

For me svn 6018 as no problem at this point with FPC 2.6 and Lazarus 0.9.30.4RC2.
The only change need to make it compile and work is to revert 6017 that make use of an undefined WA_ACTIVE.

All versions prior to 2.6.0 (I exclude the youngest 2.5.1 revisions here) did not know about the Delphi syntax, so if you say that GLScene is compiled in Delphi mode your condition should be correct now.

Hi,

I downloaded the deb's on monday. I unpacked them and while I can install fpc fine, I can't install lazarus on my ubuntu 10.04 laptop. I get a dependency problem that can't be resolved.
I explicitly excluded the qt4-related files but I still get problems (sorry, it's in dutch) :

Lazarus from the repository (0.9.28.2) installs fine, but I think I need a newer version to try some things with fpvectorial.

I'll try on a Opensuse 12.1 system.

Koenaad Lelong.

Lazarus can still run happily with libgdk-pixbuf version 2.0.0 (at least on Suse)

lazarus-ide-0.9.30.4 is afhankelijk van libgtk2.0-0 (>= 2.24.0); maar: Versie van libgtk2.0-0 op dit systeem is 2.20.1-0ubuntu2.1.

Minimum gtk2 version is 2.8.0

Is there some swicht to ignore dependecy failures (like --nodeps for rpm), you might try that.

Alternatively just install fpc 2.6.0 and build Lazarus from sources.

Bart,
I wanted to report my experience with installing the new lazarus, with ubuntu 10.04 LTS.
It's been a while I used lazarus under linux, so I'll have to search for a how-to, to make lazarus from sources.

Thanks,

Koenraad

Hi,

I just tried to install lazarus on opensuse 12.1 (rpm's). After some problems with a wrong fpc.cfg I could start lazarus. Compiling a little test-app was OK.
But when I tried to install a package, I got complaints about not finding the unit of the package. AFAIK, all is configured OK. Where do I have to look ?
I tried with running startlazarus as root, but that didn't help.

Regards,

Koenraad

This is my process for setting up fpc and lazarus on a new computer

1) I create a folder

mkdir ~/programming
cd ~/programming

2) download and extract a bootstrap compiler from:

ftp://ftp.freepascal.org/pub/fpc/dist/2.6.0/bootstrap/

yours is probably
wget
ftp://ftp.freepascal.org/pub/fpc/dist/2.6.0/bootstrap/i386-linux-ppc386.bz2 or
ftp://ftp.freepascal.org/pub/fpc/dist/2.6.0/bootstrap/x86_64-linux-ppcx64.bz2

tar -jxf ./*.ppc*.bz2

3) download freepascal

3-a) fpc trunk (2.7.1)

svn checkout http://svn.freepascal.org/svn/fpc/trunk fpc

3-b) fpc fixes (2.6.1) basically 2.6.0 with patches that fix bugs found in 2.6.0

if you would rather use the released fpc then maybe the fixes branch is what you want:

svn checkout
http://svn.freepascal.org/cgi-bin/viewvc.cgi/branches/fixes_2_6/ fpc-2.6.1

4) download lazarus

svn checkout http://svn.freepascal.org/svn/lazarus/trunk lazarus

5) compile and install fpc

cd ./fpc
PP=~/programming/ppc386 make all
sudo PP=~/programming/ppc386 make install

6) create and /etc/fpc.cfg file

./utils/fpcmkcfg/fpcmkcfg -o /etc/fpc.cfg

edit /etc/fpc.cfg file and search replace "-Fu/units/" with "-Fu/usr/local/lib/fpc/$fpcversion/units/"

7) compile lazarus

cd ../lazarus
make all

create a link to lazarus in /usr/bin so you don't have to "install" lazarus

sudo ln -s ~/programming/lazarus/lazarus /usr/bin/

that's it.

For convenience I sometimes link /usr/local/lib/fpc to /usr/lib/fpc

Regards,

Andrew

This is great info Andrew.
I'll try it on Ubuntu 12.04 later.

The Lazarus team is happy to announce that Lazarus 0.9.30.4RC2 is available for download from: http://sourceforge.net/projects/lazarus/files/

I'm not sure whether I got the latest version for Win7 (http://freefr.dl.sourceforge.net/project/lazarus/Lazarus%20Windows%2032%20bits/Lazarus%200.9.30.4/lazarus-0.9.30.4-fpc-2.6.0-win32.exe)

Please, let me know if you find any problems with these release candidates. Also let me know if you installed it without any problem.

The installer refers to an old D:\lazarus931\ folder, possibly found in my user settings. I couldn't find out how to install it in a "clean" way, into D:\lazarus934\, independently from existing installations. The "IDE Internals" show an mix from several installations:

Lazarus version: 0.9.30.4
Lazarus svn revision: 35940
Lazarus build date: 2012/03/14
Lazarus was compiled for i386-win32
Lazarus was compiled with fpc 2.6.0

Global IDE options:
Primary config directory=C:\Users\dodi\AppData\Local\lazarus Secondary config directory=D:\lazarus934
LazarusDirectory=D:\git2\lazarus\
CompilerFilename=D:\lazarus931\fpc\2.4.4\bin\i386-win32\fpc.exe Real CompilerFilename=D:\lazarus931\fpc\2.4.4\bin\i386-win32\fpc.exe CompilerMessagesFilename=
FPC source directory=D:\lazarus931\fpc\2.4.4\source\ Real FPC source directory=D:\lazarus931\fpc\2.4.4\source\ Test directory=C:\Users\dodi\AppData\Local\Temp\

It looks as if the desktop shortcut
D:\lazarus934\lazarus.exe
is incomplete, lacking the proper -pcp

After adding
--pcp=D:\lazarus934
still something's wrong with the settings. The IDE Internals now look good:

Global IDE options:
Primary config directory=D:\lazarus934\
Secondary config directory=D:\lazarus934
LazarusDirectory=D:\lazarus934\
CompilerFilename=D:\lazarus934\fpc\2.6.0\bin\i386-win32\fpc.exe Real CompilerFilename=D:\lazarus934\fpc\2.6.0\bin\i386-win32\fpc.exe CompilerMessagesFilename=
FPC source directory=$(LazarusDir)fpc\$(FPCVer)\source\ Real FPC source directory=D:\lazarus934\fpc\2.6.0\source\ Test directory=C:\Users\dodi\AppData\Local\Temp\

also the fpc.cfg in above bin directory looks correct, but at startup a "Fehler" box appears, telling that the expected target files were not found. The FPC Internals show the default Path:

Environment variables:
PATH=C:\windows\system32;C:\windows;C:\windows\System32\Wbem;C:\windows\System32\WindowsPowerShell\v1.0\;C:\Program Files (x86)\QuickTime\QTSystem\;C:\Program
Files\TortoiseSVN\bin;D:\lazarus\fpc\2.2.4\bin\x86_64-win64

which obviously includes a very old Lazarus/FPC bin directory. What can I do to clear the PATH, so that it only contains the minimal set of directories required to run Lazarus, without affecting other applications?

DoDi

Please, let me know if you find any problems with these release candidates. Also let me know if you installed it without any problem.

Installing into an new (clean) Win7 user account seems to work, but this IMO is a poor solution.

Now the well known docking problems still exist, see Mantis 18525. What's so problematic with integrating the already supplied patch, so that both applications and IDE can use docking???

DoDi
