Thanks, I have configured also for f77 as you suggest.

The configure now completes, however it outputs a strange error message:

*** Fortran 90/95 compiler
checking whether we are using the GNU Fortran compiler... no
checking whether f95 accepts -g... yes
checking for Fortran flag to compile .f files... none
checking for Fortran flag to compile .f90 files... none
checking whether f77 and f95 compilers are compatible... no
configure: WARNING: *** Fortran 77 and Fortran 90 compilers are not link
compatible
configure: WARNING: *** Disabling Fortran 90/95 bindings

I have checked f77 invokes the proper Studio11 compiler.
And of course the objects are compatible between all Studio 11 compilers...

Then the make fails in orte/mca/pls/base with message
"pls_base_context.c", line 48: undefined symbol: MAXHOSTNAMELEN

Any further idea ?

PS. I attach the relevant output.
