Hi,
I have code that consists of a non-parallelized (statically linked) library that I reuse across various projects, and some user code that calls this library from OpenMP-parallelized loops. After observing numerous data races in the library routines, which I though I had written in a thread-safe way, I realized
that the sequential library itself has to be compiled with -qopenmp, even though it does not use OpenMP at all.
I was wondering what the best practice is when creating a sequential library that can be used both with OpenMP and sequential user code.
Are there any problems when linking against a library compiled with -qopenmp if the user code itself is compiled without -qopenmp?
Thanks,
Richard
