Compiling projects
-
Hi,
I'm new of this forum.I try to compile a project made by an other one. I've installed QT Creator 2.0.1 and mingw 4.5.2 to build it.
I obtained this error messages:c:/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../../mingw32/bin/ld.exe: cannot find -lQtXml4
c:/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../../mingw32/bin/ld.exe: cannot find -lQtGui4
c:/mingw/bin/../lib/gcc/mingw32/4.5.2/../../../../mingw32/bin/ld.exe: cannot find -lQtCore4
How can I manage this?
Thanks!!

bq. I try to compile a project made by an other one. I’ve installed QT Creator 2.0.1 and mingw 4.5.2 to build it.
Have you installed Qt?
-
"QT += xml" was originally written in the pro file.
this is what I've done:- install the QT SDK
- install mingw
- run configure.exe under "C:\Qt\2010.05\qt"
- open project
- build->run qmake and it return this messages:
Starting: "c:/qt/2010.05/qt/bin/qmake.exe" C:/Develop/TEST/J6PROJ/J6PROJ.pro -r -spec win32-g++ c:\Qt\2010.05\qt\bin\rcc.exe: File does not exist '..\J6PROJ.qrc'
c:\Qt\2010.05\qt\bin\rcc.exe: File does not exist '..\J6PROJ.qrc'
The process "c:/qt/2010.05/qt/bin/qmake.exe" exited normally.
And this warning:
Qmake does not support build directories below the source directory- After that I build project build->Build Project and obtain that errors.
Thanks.

IMO, this sounds like the path doesn't contain the route to the libraries, so they aren't being found. If this is the case, maybe using -Lfulllibroute instead of -llibname could be useful (-L full lib route, -l library name). Also, I don't know which $PATH(s) mingw's ld looks into...

I've uninstall Qt sdk and minigw and reinstall only Qt sdk.
I've load my project, run qmake and build project obtaining a lot of error like:_undefined reference to
__gxx_personality_sj0'_ _undefined reference toUnwind_SjLj_Register'
_undefined reference to_Unwind_SjLj_Unregister'_ _undefined reference toUnwind_SjLj_Resume'It seems like a non correct library link.

After such a tremendous software removal and reinstallation... a full clean build is recommended, IMHO.

I have reinstalled the Qt SDK and after compile my project I obtained this errors:
./release\moc_mainwindow.o:moc_mainwindow.cpp:(.text+0xb7): undefined reference to `__gxx_personality_sj0'
./release\moc_mainwindow.o:moc_mainwindow.cpp:(.text+0xca): undefined reference to `_Unwind_SjLj_Register'
./release\moc_mainwindow.o:moc_mainwindow.cpp:(.text+0x113): undefined reference to `_Unwind_SjLj_Unregister'
./release\moc_mainwindow.o:moc_mainwindow.cpp:(.text+0xa76): undefined reference to `_Unwind_SjLj_Resume'
for each file.
How can manage this? Which library contain that reference?
Please help!
