I get openmpi-1.0.2 to compile on a (small) G5 cluster. The C and C+ + compilers work fine so far, but the mpif77 and mpif90 scripts send the wrong flags to the f77 and f90 compilers. I've attached the config.log , make.out, the error
messages, and the environment variables.
for f77 I get :Error: bad option:  -Wl,--export-dynamic
and for f90 :
cf90-78 f90fe: ERROR in command line
  -N option has an illegal argument "l,--export-dynamic".
f90fe-912: 1 Errors found in command line.  Compilation aborted.

I feel I am soooo close. :-)
Sorry about the delay in replying -- for some reason, this message slipped through the cracks. Anyway, the problem is that older versions of the Absoft compilers didn't speak the same language as other compilers in the OS X (and general Unix) world. In particular, they didn't know that -Wl, meant the rest of the option should be passed to the linker as an argument when the compiler invoked the linker. Absoft has since updated their compilers to fix the issue, so upgrading the compilers will fix the issue.

The other option is to just not do anything that requires special flags to the linker. This means disabling our dynamically loaded components (and having them compiled into libmpi.so) and turing off some code we have for high-performance networks (Myrinet and InfiniBand, in particular). Adding the configure options:

  --without-memory-manager --disable-dlopen

Should give you a build that will avoid passing arguments that will annoy the Absoft compiler.


Hope this helps,

Brian
