Building Open MPI 1.0.1 on a PowerMac running OS X 10.4.4 using 1) Apple gnu compilers from Xcode 2.2.1 2) fink-installed g77 3) latest g95 "G95 (GCC 4.0.1 (g95!) Jan 23 2006)" (the binary from G95 Home)
setenv F77 g77 setenv FC g95 ./configure In the G95 section of the configure I get checking size of FORTRAN integer(selected_int_kind(2))... unknown configure: WARNING: *** Problem running configure test! Gzipped config.log attached.If I change to the older Fink g95 "G95 (GCC 4.0.2 (g95!) Dec 19 2005)" I don't see this problem
