Author: goodell Date: 2013-01-03 13:12:13 -0600 (Thu, 03 Jan 2013) New Revision: 10820 Modified: mpich2/trunk/configure.ac Log: fix dylib creation on OS X if fortran is disabled This is a follow-on to r10622 and tt#1570. Eric Borisch reported that shared libraries were not generated on Darwin platforms when `--disable-f77` and `--disable-fortran` are passed. The fix in r10622 was buggy, but hopefully this one works a bit better. If you're debugging this in the future, search for `_lt_disable_F77` in the generated configure file to help understand why we expect `F77=no` to prevent libtool problems (and possibly help debug the future problem).
