Hi all, I have found something that is somehow common within my google research but I could not find any topic that solves the issue. Except perhaps this one (in French) http://www.developpez.net/forums/d787443/c-cpp/c/dll-manquante-pthread-lib/#post4532634 but I do not understand how he really achieved it.
In order to reproduce the issue I used the hello world from wikipedia: http://en.wikipedia.org/wiki/OpenMP#Fortran_77 I named it omp.F Compiled with: gfortran -o omp omp.F -fopenmp -lpthread This works: $ ./omp HELLO WORLD FROM THREAD 0 HELLO WORLD FROM THREAD 3 HELLO WORLD FROM THREAD 2 HELLO WORLD FROM THREAD 1 THERE ARE 4 THREADS Then I tried to compile it for Windows 64 and 32 bits but it fails when running. Compiled with: x86_64-w64-mingw32-gfortran -o omp omp.F -static -fopenmp -lpthread -lpthreadGC2 i686-w64-mingw32-gfortran -o omp omp.F -static -fopenmp -lpthread -lpthreadGC2 or x86_64-w64-mingw32-gfortran -o omp omp.F -static -fopenmp -lpthread i686-w64-mingw32-gfortran -o omp omp.F -static -fopenmp -lpthread When running it under an XP computer (32 or 64 bits depending on the binary) it always fails with: pthreadGC2.dll was not found. I really need this in static so adding the flag -static should have solved and used the .a file, isn't it? On my computer I have the mingw-pthread package installed: mingw32-pthreads-2.8.0-14.cvs20110104.fc15_cross.noarch mingw64-pthreads-2.8.0-14.cvs20110104.fc15_cross.noarch Also: # locate *pthreadGC2* /usr/i686-w64-mingw32/sys-root/mingw/bin/pthreadGC2.dll /usr/i686-w64-mingw32/sys-root/mingw/lib/libpthreadGC2.a /usr/x86_64-w64-mingw32/sys-root/mingw/bin/pthreadGC2.dll /usr/x86_64-w64-mingw32/sys-root/mingw/lib/libpthreadGC2.a I hope there is a solution, Fabien _______________________________________________ mingw mailing list [email protected] https://admin.fedoraproject.org/mailman/listinfo/mingw
