hello,
i want to use another linker than g++ in qmake,
i find that i can change the compiler my defining something as:
QMAKE_CXX=mpicxx
but it works only for doing the object files .o ,for the last step ,linking, Qt
still use g++ and i got some error then:
[dma@maestro sphere]$ make
mpicxx -c -pipe -Wall -W -O2 -g -pipe -m64 -DNO_GRAPHIC -DNO_TEXT -DOPTIM -DMPICH_IGNORE_CXX_SEEK -DSPHERE_MPI -DQT_NO_DEBUG -DQT_SHARED -DQT_THREAD_SUPPORT -I/usr/lib64/qt-3.3/mkspecs/default -I. -I. -I/usr/local/CCfits -I/usr/local/include/CCfits -I/usr/local/cfitsio -I/usr/include/CCfits -I/usr/local/boost_1_42_0 -I/usr/local/include -I/usr/lib64/qt-3.3/include -o sphere.o sphere.cpp

so i have to link manually as this :
