Hello all,
I'm experiencing weired problems when trying to link my application
with MinGW.
After generate my Makefile I have the Qt libraries added but no -l
options for Qt libraries. My "linking" line is this:
g++ "CMakeFiles/oigui.dir/oigui.cpp.obj" -o oigui.exe
-Wl,--out-implib,liboigui.dll.a
-Wl,--major-image-version,0,--minor-image-version,0 -LZ:\studies
-LC:\Qt\4.3.4-static\lib -lqgarwin C:\Qt\4.3.4-static\lib\libQtCore.a
C:\Qt\4.3.4-static\lib\libQtGui.a C:\Qt\4.3.4-static\lib\libQtXml.a
-lmingw32 -lqtmain -lgdi32 -lcomdlg32 -loleaut32 -limm32 -lwinmm
-lwinspool -lmsimg32 -lkernel32 -luser32 -lshell32 -luuid -lole32
-ladvapi32 -lws2_32
With this, I have missing symbols for all calls to Qt functions. Of
course, if I add:
–lQtCore –lQtGui –lQtXml
To my linking line, everything links ok.
This problem does not occurs on Linux with gcc, but only with MinGW. My
point is, am I missing some point in my project's configuration?
I added my CMakeLists.txt to clarify.
Another important remark is that my Qt version is compiled as static.
So, I have no dll's available, only .a files.
Thanks in advance,
