I have no success building open-mpi with -fdefault-real-8: cd openmpi-2.0.1 FCFLAGS=-fdefault-real-8 ./configure ... checking for C type matching bit representation of REAL*16... pending checking if long double == REAL*16... no checking if gnu compiler __float128 == REAL*16... works! checking for C type matching bit representation of REAL*16... yes checking if Fortran compiler supports DOUBLE PRECISION... yes checking size of Fortran DOUBLE PRECISION... 16 checking for C type corresponding to DOUBLE PRECISION... long double checking alignment of Fortran DOUBLE PRECISION... 16 checking for corresponding KIND value of DOUBLE PRECISION... C_LONG_DOUBLE checking KIND value of Fortran C_LONG_DOUBLE... (cached) 10 checking if Fortran compiler supports COMPLEX... yes checking size of Fortran COMPLEX... 16 checking for C type corresponding to COMPLEX... not found configure: WARNING: *** Did not find corresponding C type configure: error: Cannot continue Any ideas? --Jan _______________________________________________ devel mailing list devel@lists.open-mpi.org https://rfd.newmexicoconsortium.org/mailman/listinfo/devel
