Hi,

I actually managed to reproduce it with a minimal test case (attached):

$ guix build -f mpich-test.scm

The same program outside the container works just fine:

$ guix environment --ad-hoc mpich -- mpiexec -np 2 "/gnu/store/8i1dci1wxd6c0q6a2cz4kgb8adfk8rrz-mpi-init"
np = 2, rank = 0
np = 2, rank = 1


‘MPL_get_sockaddr’ uses ‘getaddrinfo’ for host name lookup.
Interestingly, ‘getaddrinfo’ fails in the build environment when passed
the flags that ‘MPL_get_sockaddr’ uses:

(computed-file "getaddrinfo"
               #~(pk #$output
                     (getaddrinfo "localhost" #f
                                  (logior AI_ADDRCONFIG AI_V4MAPPED)
                                  AF_INET
                                  SOCK_STREAM
                                  IPPROTO_TCP)))

However, if you comment AF_INET, SOCK_STREAM, and IPPROTO_TCP, it works.

Now we need to see why the ‘ai_family’ hint is causing troubles in
glibc, and perhaps in parallel try to work around it in MPICH…
