Peter, I was the one who reported this bug to automake: http://debbugs.gnu.org/cgi/bugreport.cgi?bug=13928 ;-) And this bug is /present since the beginning/. But where did you get the impression that this may get fixed in 1.14.2? Anyway, this $(LN_S) is there to prevent having variable references in _SOURCES files, thus circumventing the subdir-objects bug in automake. We (in VT) are building some sources twice. Once with the $(CC) compiler and a second time with the $(MPICC) compiler. And for this we are now making symlinks in a new directory, so that it looks like they have the same paths for both builds.

Re: [OMPI devel] Fwd: [OMPI users] missing link option for openmpi-1.8.2rc2 on Linux
I think it's just libmpi_java that needs that linker flag, so it shouldn't affect anyone else On Jul 25, 2014, at 8:59 AM, Jeff Squyres (jsquyres) wrote: > OMPI developers -- > > Is "-z noexecstack" a linker option we should test for in configure, and use > it if it works? > > Are there any side effects that could cause problems? > > > Begin forwarded message: > >> From: Siegmar Gross >> Subject: [OMPI users] missing link option for openmpi-1.8.2rc2 on Linux >> Date: July 25, 2014 at 2:44:48 AM EDT >> To: >> Reply-To: Siegmar Gross , Open MPI >> Users >> >> Hi, >> >> I installed openmpi-1.8.2rc2 on "openSUSE Linux 12.1 x86_64" >> with Sun C 5.12 and get the following warning if I run a small >> Java program.

Re: [OMPI devel] Fwd: [OMPI users] missing link option for openmpi-1.8.2rc2 on Linux
Understood. I'm asking, in principle, as to whether we should use -z noexecstack for the whole thing -- i.e., is this just a good "best practice" kind of flag we should enable?
