Compilling Qt Creator 2.2 on FreeBSD
-
Did you try running c++filt on the symbol name to demangle it and then went on a search for where it is actually defined? You might be needing an additional library or something to get it.
PS: Patches to Qt Creator to fix the build are welcome:-)

Thanks Tobias!
Running c++filt get me this result:
@c++filt _ZTVN5Botan11POSIX_TimerEvtable 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:

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:
bq. 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":http://pastebin.com/7pQyvFDj 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:

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.
-
We do not require a working Qt in Qt Creator. QMake based projects do, since qmake itself is part of Qt and we of course need to find that.
You can use qmake based projects without Qt though, or CMake or generic projects (both of which do not even ask for Qt).
-
Pretty interesting. I've never heard Qt Creator could use another file format besides .pro to set up a project structure. I was thinking one must use a .pro file in order to Qt Creator recognise and index a project tree even for non Qt projects. This is a usefull information.

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

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:
QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv failed: Resource temporarily unavailable
QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv failed: Error 0

QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv failed: Error 0
QIconvCodec::convertFromUnicode: using Latin-1 for conversion, iconv failed: No such file or directory -
No surprise there considering that the fix did not go into the 2.2 branch:-)
Please try master (or backport the patch from there, the SHA is in the bugreport).

You will have to clone the sources from "gitorious":https://qt.gitorious.org/qt-creator and build Creator yourself.
Alternatively, you can try one of the snapshots on "get.qt.nokia.com":http://get.qt.nokia.com/qtcreator/snapshots/
