Vicente, All,
On 2016-07-07 16:47 +0100, Vicente Olivert Riera spake thusly:
> We include a file containing cached values for Fortran tests that are
> performed at the configure step. These tests fail when cross-compiling
> and this is known upstream. See:

Too bad... :-/
> In that thread the upstream maintainer admits that "cross compiling
> OpenMPI is a known issue" and the way to workaround this is to
> "pre-populate configure's answers to the Fortran tests (so that it
> doesn't actually have to run anything)"
Meh... :-/

No nedd for the leading $(TOPDIR)/ as $(TOPDIR) is guaranteed by
Buildroot to be the CWD when running Buildroot.

[--SNIP--]
I would have wrote it like that:
OPENMPI_CONF_ENV += \
ompi_cv_fortran_sizeof_CHARACTER=1 \
ompi_cv_fortran_sizeof_LOGICAL=4 \
ompi_cv_fortran_sizeof_LOGICALp1=1 \
[...]
Otherwise, I don;t see a better solution, indeed... :-/
Or, instead of passing it in the environment, we can provide a configure
cache file, no?
