In that case, I'd suggest you explicitly list -lmpich, -lopa and -lmpl
in there for now. You can always look at "mpicc -show" for any released
version to figure out what all flags/libs are being set.

That may be true, but it is a goal of Debian to be able to build the
archive using binutils-gold, which requires each ELF object (shared
library or executable) to link with every library whose symbol it uses.
As I understand it, the reason is that binutils-gold allows for much
faster build-time and run-time linking than standard binutils.
Feel free to ignore this, but at some point this will become a
release-critical bug.

The best method is to use pkg-config to find what libraries need to be
linked in. Currently, this list is libmpich, libmpl and libopa, if you
are using generic TCP/IP and shared memory support. But if you enable
other modules, more libraries might be required.

Greetings,
On mips(el) and s390, the scalapack build fails with:

All of these symbols seem to be in libmpl.so, so linking libmpich2.so
with libmpl.so would fix this problem.
You can see the error in at the end of the package build:

It's interesting that this works fine on other platforms, that it either
ignores or manages to find libmpl... But in general, it's best to link
to all of the libraries whose symbols you use, I'm pretty sure it's also
a requirement of binutils-gold.
Thanks,
