Hi!
How to build lazarus with Qt4?? I set the interface of lazarus to Qt and try rebuild only LCL, but when it is rebuilding, it stops because it don't found qt4.pas.
I'm doing all steps of wiki
(http://wiki.lazarus.freepascal.org/Qt_Interface).<http://wiki.lazarus.freepascal.org/Qt_Interface%29.> ..
Qt 4.3.1 is installed from ports and my Lazarus snapshot verion 0.9.25 of 22-nov-2007...
The page is still correct and it works here under linux. Please open a terminal and try this:
cd lazarus/lcl
make LCL_PLATFORM=qt clean all OPT=-vut > log.txt
Then take a and find out, why FPC does not find/like the file lcl/interfaces/qt/qt4.pas

probably because the linker does not find libqt4intf.so. I have so bsd experience. Are you interested in
creating a libqt4intf.so for bsd :-). ?
if so start from the linux source code and compile script.
kind regards,
Den Jean
I'm interested, but I don't know the correct steps to do the libqt4intf... I do:
1) Copy Qt4 sources to my home directory;
2) Build Qt4;3) Copy the compile_lib.bash to compile_lib_fbsd.sh and change it to use my Qt4 (in my home directory)
4) Run compile_libfbsd.sh
5) Put the libqt4intf.so in /usr/local/lib....
6) Rebuild Lazarus without sucess... :(
How you do the libqt4intf.so in Linux?

pm wrote6) Rebuild Lazarus without sucess... :(
in point 5 you succesfully got a libqt4intf.so ?. Great. So the rest is just compiling lazarus.
cd lazarus
make LCL_PLATFORM=qt clean all OPT=dUSE_QT_4_3
and look at output
The option USE_QT_4_3 is if you use the Qt 4.3.1 libs. Do not add it if you used the Qt 4.2.3 libs.
Did you put llibQtCore.so.4 and libQtGui.so.4 in /usr/local/lib as well ? and ran ldconfig or the bsd equivalent ?
The resulting executable ofcourse depends on Qt :-)
ldd ./lazarus | grep -i qt
libqt4intf.so => /usr/lib/libqt4intf.so (0xb7d21000) libQtCore.so.4 => /usr/lib/qt4/lib/libQtCore.so.4 (0xb7a51000) libQtGui.so.4 => /usr/lib/qt4/lib/libQtGui.so.4 (0xb7294000)
(/usr/lib on my system)

but there are many LINUX ifdefs. (see below)
It would be complicated to add "... or FREEBSD or NETBSD" everywhere etc.
I am considering to replace LINUX with UNIX everywhere, but need to check if this does not break things.
Can you also read Lazarus Qt Widget Set List.
I will ask there what they think about that.

try to run the demoes of c++ qt4
e.g.
cd qt-x11-opensource-src-4.3.1/demos/textedit
./textedit
try to build the demo of the fpc qt4 bindings and run those
make sure you do not have 2 Qt's mixed in the library paths. Although different versions are claimed to be compatible, a different ./configure by distrib vendor may even make a same version a completely different Qt lib.
There is a help about in the bindings mainwindow demo that gives the Qt version.
use ldd to find the the path of the used lib on your system
ldd ./mainwindow | grep -i qt

I ran qt4 demos and all right! Lazarus demos crash...
Attached is the backtrace of lazarus and ldd of lazarus example (hello).
I will update my lazarus to a recent snapshot...

My 3700+ already had SSE3, and afaik X2's are newer. So I would be very surprised if it didn't support SSE2

pm wroteI will try disable SSE2 instructions...
It was a long shot ...
can you tell us which freebsd ? if I have time I may give it a try
please try latest lazarus svn source again.
(you are already using fpc 2.2.0 I see, Ok).
Well, FreeBSD is my personal choice. It´s stable and fast, more than Linux or Windows (to me), because it has less drivers (and less bullshit, is a joke :D) than... And have the ports system...
I´m creating a project (http://pascalscada.blogspot.com in portuguese) to allow create industrial applications using lazarus or delphi, prataform independent (only on lazarus). I think that an application that ran in FreeBSD, ran in Linux too, but an application that ran in Linux can´t run in FreeBSD always. Because of this, it's my personal choice (to reduce tests between similar OS).
Why QT? Because GTK and GTK2 disapoint in some aspects. Some components of my project lost some properties under GTK (as Color property). Then Qt is my next choice to test my project...
Ok, I will try an updated snapshot of lazarus. And yes, I'm using fpc 2.2.0. I can't disable suport of SSE2 instructions on my QT4 instalation...

Hi!
I do some tests in my FreeBSD 6.1. In another FreeBSD 6.2 I build QT from ports (that is an automated process, that applies some patchs before build). In my FreeBSD 6.1 I build QT without ports (./configure, make, make install) and I got the same result, but with a more detailed backtrace (because QT compiled with debug enabled).
I have to change qt43.pas that uses defines LINUX and not UNIX...

I tried FreeBSD, but X always seg failed, so then I tried PC-BSD.
The qt4 ports install include files to close to qt3 include files (you fall on qt3 files first). The PREFIX stuff does not work. The qt4-gui ports does not link with the PREFIX (does not find libqtcore, whatever you do with ldconfig)
If you play with ldconfig, bash becomes unstable-> you cannot launch any program or any new konsole anymore, the messages you get are common problems (google says: update ports recompile everything, but my ports are fresh :-) -> reboot -> I have never rebooted this much :-(. (BSD ? :-)
with LD_LIBRARY_PATH and a manually (no ports) compiled qt4 (put in /usr/local/KDE4) I can finally compile lazarus (some pthreads link hurdle aside)
lazarus compiled with:
#!/bin/bash
cd lazarus
export LD_LIBRARY_PATH=/usr/local/KDE4/lib
gmake LCL_PLATFORM=qt clean all OPT="-dDEBUG -dUSE_QT_4_3 -k'-L/usr/local/KDE4/lib' -k'-lpthread'"
qt4intf compiled with:
cat ./compile_lib.bash
#!/bin/bash
export QT4=/usr/local/KDE4
export QT4I=$QT4/include
export LD_LIBRARY_PATH=$QT4/lib
if [ -e "$LD_LIBRARY_PATH/libQtCore.so.4" ]
then

Rebuild QT without SSE2 is a VERY long shot :D... And I disable Qt suport to glib.
After disable this, lazarus + QT + FreeBSD works, with some bugs and slow startup, but works!

I don't remember if I'm running lazaurs with ./startlazarus or ./lazarus, I will see if this ocurs with GTK2..
Yes, QT4 ports don't work, then I build QT4 manualy. My steps:
1) ./configure -prefix /usr/local/ -no-sse2 -no-glib do QT4 install in /usr/local and disable sse2 and GLib suport.
2) gmake, gmake install
3) cd lazaurs, gmake LCL_PLATFORM=qt OPT="-dUSE_QT_4_3" I don't need specify where my QT4 librarys are installed because I put it in /usr/local/(bin, lib, share...) in ./configure...
4) Run ./startlazarus, wait a little time and Have QT4 running with lazarus under FreeBSD

Hi,
I've just readed thread on fpc-pascal list, and seen your sse2 problem with qt4.
I had same thing on linux (Fedora Core 3) and qt4. Just recompile your qt4 libs with --no-sse and you'll get bingo ;)
cheers,
