Do you use -fopenmp on the link line? seems not, below should be the corresponding command line leading to the error, going to check the openblas buildsystem ... gfortran -frecursive -o zblat1 zblat1.o ../libopenblaso_power8-r0.2.18.a -lm -lpthread -lgfortran -lm -lpthread -lgfortran If anything in ../libopenblaso_power8-r0.2.18.a or zblat1.o is compiled with -fopenmp, then that is the bug, -fopenmp should be used not just during compilation, but also during linking if there is any object compiled with -fopenmp. yep, and I think I at least see where is the difference between ppc64 and other arches - the other arches don't build the tests (in our rpm builds), thus don't call the wrong link command ... switching to openblas, because the root cause is there Looks like a simple problem of the make flags not getting passed to the recursive processes. |
