More specifically building the new “flang” compiler and compiling openmpi with the combination of clang/flang rather than clang/gfortran.
Configure is passing (including support for 16 byte REAL and COMPLEX types. However there is one file that uses REAL128 and CONPLE(REAL128) and I’m getting type in supported KIND=-1 errors. (Quick aside I’m surprised that the one file is using the ISO_FORTRAN_ENV type names but configure is only checking for the non-standard REAL*# names. Feels like an oversight to me.) >From what I’ve been able to find (and reading their iso_fortran_env.f90 module file the compiler should support the two types. I barely know enough FORTRAN to be dangerous (took one semester of F77 in like 1996) so I’m not really sure what I’m looking at here or what to try next. I would really like to provide an openmpi build to my users that is a “pure LLVM” build. -Alan -- a...@madllama.net http://humbleville.blogspot.com
