Thanks. In half an hour I'll know how this works (my RISC-V system is quite slow). For others who stumble on this thread, it is "-C" not "-c". Jeff On Tue, Sep 7, 2021 at 3:35 PM Gilles Gouaillardet via users < users@lists.open-mpi.org> wrote: > Hi Jeff, > > > Here is a sample file I used some

Hi Jeff, Here is a sample file I used some times ago (some definitions might be missing though ...) In order to automatically generate this file - this is a bit of an egg and the chicken problem - you can run configure -c on the RISC-V node. It will generate a config.cache file. Then y

I am attempting to cross-compile Open-MPI for RISC-V on an x86 system. I get this error, with which I have some familiarity: checking size of Fortran CHARACTER... configure: error: Can not determine size of CHARACTER when cross-compiling I know that I need to specify the size explicitly using a
