Compilling Qt Creator 2.2 on FreeBSD
Page |
1 |
Hi!
I’m trying to compile Qt Creator 2.2 on a FreeBSD machine. Qt version there is 4.6 and, so, I first compiled successfully Qt 4.7.3 locally on my machine. Attempts to compile Qt Creator 2.1 all failed and, so, I’ve tried to compile v2.2. It compiles smoothly but, when I try to run it, it prints this message:
Failed to load core: /home/gustavo/prog/lib/qtcreator/plugins/Nokia/libCore.so: Cannot load library /home/gustavo/prog/lib/qtcreator/plugins/Nokia/libCore.so: (/home/gustavo/prog/lib/qtcreator/libBotan.so.1: Undefined symbol “_ZTVN5Botan11POSIX_TimerE”)
Does anyone know what may be causing this problem?
Thanks!

Thanks Tobias!
Running c++filt get me this result:
- c++filt _ZTVN5Botan11POSIX_TimerE
- >> vtable for Botan::POSIX_Timer
So, there’s something in Botan build configuration preventing it to load this class at build time. Fortunately, I’ve noticed Qt Creator 2.0 was showing this same problem, and, for this version, there’s a patch in FreeBSD ports, namely:
- --- ./src/libs/3rdparty/botan/src/src.pro.orig 2010-08-24 11:46:09.000000000 +0400
- +++ ./src/libs/3rdparty/botan/src/src.pro 2010-11-29 03:49:46.829707166 +0300
- -564,10 +564,6
- timer/gettimeofday/tm_unix.cpp
- }
- -linux*-g++* {
- - SOURCES += timer/posix_rt/tm_posix.cpp
- -}
- +SOURCES += timer/posix_rt/tm_posix.cpp
- -linux*-g++* {
- - LIBS += -lrt
- -}
- +LIBS += -lrt
This fix the Botan::POSIX_Timer problem. Now I’m able to launch Qt Creator. Nevertheless, another problem has arrived: when I try to load a project file, a dialog appears displaying this message:
No valid qt versions found. Please add a qt version in Tools/Options or via the maintenance tool of the SDK
This is really strange, because the path of my Qt local installation is already set up correctly in Tools/Options (Qt Creator just found it automatically). Any idea what went wrong this time?
Does this patch [pastebin.com] fix the build for you?
Is the Qt version marked as valid in Tools->Options->Qt4? My guess is that this worked. Is there any tool chain set up in Tools->Options->Qt4? Does it have a sane ABI (hover it, please)? My guess that this is what is going wrong here. If it indeed is: Can you please provide me with the output of gcc -dumpmachine? Thanks!
Everything in Qt4 configuration seems to be ok:

About the patch you provided, I’m gonna testing it to provide you a feedback.
Thanks.
Yeap, it does not know “amd64-undermydesk-freebsd”, so it will not recognize that this is something compatible with your freebsd Qt… Plus it obviously assumed your Qt to be linux, too.
So there is quite a bit going wrong. Could you please send me your libQtCore.so (the actual lib, not the symlinks;)? That would be highly appreciated!
How do I send it to you? By mail?
By the way, let me point a related usability bug in Qt Creator: at my work, only some projects are currently using any Qt library. Nonetheless, we want to use Qt Creator as our IDE for every C++ project, regardless of it being Qt based or not. So, for many projects, it’s not necessary that Qt Creator finds any Qt configuration at all. But, with this bug, we are not able to use Qt Creator even for this non-Qt projects, because Qt Creator does require a working Qt configuration for every project.
Just opened http://bugreports.qt.nokia.com/browse/QTCREATORBUG-4879 about misdetection of freebsd binaires as linux.
This will make it hard to work on freebsd since Creator will not match up the compiler with the Qt version and thus block building:-/
The only workaround I can think of right now is to feed Qt Creator with a compiler that claims via “gcc -dumpmachine” to be targetting Linux. A small script wrapper should do that… then the (now misdetected) compiler will match up with the misdetected Qt and all should be well.
Hello All,
I’ve compile the qt-creator 2.2.0 and I have the exact same error when trying to run it, i.e.
bash-4.2# bin/qtcreator
Failed to load core: /export/home/Download/Qt-creator/lib/qtcreator/plugins/Nokia/libCore.so: Cannot load library /export/home/Download/Qt-creator/lib/qtcreator/plugins/Nokia/libCore.so: (ld.so.1: qtcreator: fatal: relocation error: file /download/Qt-creator/lib/qtcreator/libBotan.so.1: symbol _ZTVN5Botan11POSIX_TimerE: referenced symbol not found)
bash-4.2# nm -C /download/Qt-creator/lib/qtcreator/libBotan.so.1 | grep _ZTVN5Botan11POSIX_TimerE
[_ZTVN5Botan11POSIX_TimerE]
bash-4.2# nm /download/Qt-creator/lib/qtcreator/libBotan.so | grep _ZTVN5Botan11POSIX_TimerE
[7605] | 0| 0|NOTY |GLOB |0 |UNDEF |_ZTVN5Botan11POSIX_TimerE
and well the patch it seems to work for FreeBSD, but I’m working in Solaris 10 and well checking the file
vim /download/qt-creator-2.2.0-src/src/libs/3rdparty/botan/src/timer/gettimeofday/info.txt
realname “Unix Timer”
define TIMER_UNIX

Solaris is listed as the “detected” OS, I don’t know how to check if the compiler does a good detection of the OS, I have both libraries, librt et libposix4, which i read were the needed libraries to get all the posix timing routines.
Do you have any ideas on how getting qtcreator to run?
Thanks in advance
Thanks Gustavo, It runs now, qtcreator, but I have the exact same problemyou had, when trying to create or open a project it says no valid qt version found! but verifying under tools/options/qt4 Qtcreator has automatically taken the qmake on the PATH variable.
And on the shell where i ran the qtcreator i found these 3 different messages repeated:
