mpich-* compilation error with 10.9

[massonseb]

I have compilation error with mpich-* packages with OS 10.9.5 when I try to update mpich-* from version 3.3.2_0 to 3.4_0.
The error is:

:info:build libtool: compile:  /opt/local/bin/clang-mp-9.0 -DHAVE_CONFIG_H -I. -I./include -D_GNU_SOURCE -D__USE_XOPEN2K8 -DSYSCONFDIR=\"/opt/local/etc/mpich-clang90\" -DRDMADIR=\"@rdmadir@\" -DPROVDLDIR=\"/opt/local/lib/mpich-clang90/libfabric\" -I./prov/sockets/include -I./prov/sockets -I./prov/hook/include -I./prov/hook/perf/include -I./prov/hook/hook_debug/include -Wall -O2 -DNDEBUG -c src/shared/ofi_str.c  -fno-common -DPIC -o src/shared/.libs/src_libfabric_la-ofi_str.o

It looks very similar to #60650 and a solution was proposed ​here

Would it be possible to use the same solution with mpich?

I moved that fix into legacysupport, so that might be the best way to go.

Just add:

PortGroup legacysupport 1.1

near the top of the Portfile. ( found by port file XYZ )

Let us know if that works, please.

Replying to massonseb:

Can you try adding the ​trivial change locally and see if it works? (And if you can build things against the resulting mpich successfully?)

I don't have a legacy system to test on.

Thanks!

Yes your change works perfectly.
I was able to compile mpich-clang90 on OS 10.9
Thank you for your quick response.
