Hi, Openmp is a MinGW64 problem, mixing pthreads with openmp is buggy. Currently I am trying to debug this in their winpthread implementation but I am no thread expert. Not by far. Any help is welcome. I have downloaded their svn repository and winpthread is in experimental/winpthread folder. Standard configure/make with CFLAGS=-g is enough to get a debug build. Also MSYS is required.
Warning! Uncommented and unindented code in there, prepare for eyesores :p A minimum test case to reproduce the hang is (compile with -fopenmp) #include <cstdio> #include <omp.h> #include <pthread.h> void *do_thread(void *) { int niterations = 200; int i; #pragma omp parallel for for (i = 0; i < niterations; i++) { printf ("ducks\n"); } return NULL; } int main() { pthread_t id; pthread_create(&id, NULL, do_thread, NULL); pthread_join (id, NULL); } _______________________________________________ Bf-committers mailing list Bf-committers@blender.org http://lists.blender.org/mailman/listinfo/bf-committers
