I have Mac OS X 10.10 (Yosemite) and 10.12 (Sierra) systems with PGI
compilers installed.
I have configured the 2.0.2rc1 tarball with
--prefix=[...] --enable-debug CC=pgcc CXX=pgc++ FC=pgfortran
I see a build failure in the libevent code:
PGC-F-0249-#error -- "No way to define ev_uint64_t"
(/Users/phhargrove/OMPI/openmpi-2.0.2rc1-macos10.10-x86-pgi/openmpi-2.0.2rc1/opal/mca/event/libevent2022/libevent/include/event2/util.h:
126)
PGC/x86-64 OSX 16.10-0: compilation aborted
I've tracked this down to libevent's configure script failing to find
uint64_t.

In fact, nearly *all* of libevent's configure test fails as a result of
that unsupported compiler flag.
Use of that flag, in turn, is due to the following
in opal/mca/event/libevent2022/libevent/configure.ac:
# OS X Lion started deprecating the system openssl. Let's just disable
# all deprecation warnings on OS X.
case "$host_os" in
darwin*)
CFLAGS="$CFLAGS -Wno-deprecated-declarations"
;;
esac
It seems this needs to change to acknowledge that not every compiler for
Mac OS X is gcc-compatible.
