--- Comment #4 from Nicolas Koenig <koenigni at gcc dot gnu.org> --- Created attachment 45536 --> https://gcc.gnu.org/bugzilla/attachment.cgi?id=45536&action=edit library Here is the library. At the moment, it has an interprocess allocator and handles the creation and reaping of images. It also has a very simple synchroniziation function. The library part still has to integrated with libgfortrans build system. I would suggest to handle it the same way libcaf_single is handled at the moment which is linked against if -fcoarray=native is specified. To compile the library at the moment, the Makefile has to edited to allow it to find libgfortran.h and libgfortran's config.h. After that 'make' will build it.
