Disclamer first:
Yes, I am testing a *beta* compiler but this is NOT about a compiler bug.
I leave it to the judgment of others whether my findings warrant any
action.
I am testing the 2.0.0rc2 tarball with the Oracle Solaris Studio 12.5-beta
for Linux.
With Studio 12.4 all is fine on the same system with identical configure
options.
The configure command options in both cases (with different $PATH):
--prefix=[...] --enable-debug --enable-mpi-cxx CC=cc CXX=CC FC=f95
With 12.5-beta (but not 12.4) I see the following failure while building
the fortran bindings:
/bin/sh ../../../../libtool --tag=FC --mode=link f95

My first observation is that f95 command line produced by libtool doesn't
look at all like the same step when using the 12.4 compiler:
libtool: link: f95 -G -KPIC .libs/mpi-ignore-tkr.o -Qoption ld -rpath
-Qoption ld
/scratch/phargrov/OMPI/openmpi-2.0.0rc2-linux-x86_64-ss12u4/BLD/opal/.libs

libmpi_usempi_ignore_tkr.so.20 -o .libs/libmpi_usempi_ignore_tkr.so.20.0.0
So, my initial diagnosis was that this is most likely a libtool bug.
BUT, I also know that autogen.pl contains logic for "Patching configure for
Sun Studio Fortran version strings".
So, I recognized that Open MPI's autogen.pl might be where the fix belongs.
Continuing on that line of though I discovered that the version strings for
the Fortran compiler have changed between 12.4 and 12.5-beta:
$ /opt/oracle/solarisstudio12.4/bin/f95 -V
f90: Sun Fortran 95 8.7 Linux_i386 2014/10/20
$ /opt/oracle/solarisstudio12.5-beta/bin/f95 -V
f90: Studio 12.5 Fortran 95 8.8 Linux_i386 Beta 2015/11/17
Notice that "Sun" is gone, and thus the patterns used by libtool no longer
match!
So, this *is* a libtool "issue", but can hardly be blamed on libtool.
FWIW: the C and C++ compiler still say "Sun" and match the patterns used by
libtool:
$ /opt/oracle/solarisstudio12.5-beta/bin/cc -V
cc: Studio 12.5 Sun C 5.14 Linux_i386 Beta 2015/11/17
$ /opt/oracle/solarisstudio12.5-beta/bin/CC -V
CC: Studio 12.5 Sun C++ 5.14 Linux_i386 Beta 2015/11/17
I checked the libtool git repo, and there is no upstream fix for this (Ralf
W., are you still on this list?)
So, for all that wind-up this posting comes down to a small addition to
autogen.sh:
