[mpich-discuss] Optimizing runtime for 4 mpiexec.hydra jobs

[Douglas G Dommermuth]

Dear mpich.org<http://mpich.org>,

I am getting an error installing mpich-3.4.3 on a MacBook Air (M1,2020) with macOS Monterey 12.1, gcc 11.2.0, g++ 11.2.0, and gfortran 11.2.0.  I used the following commands:

./configure FFLAGS=-fallow-argument-mismatch --prefix=/Users/douglasdommermuth/mpich2/mpich2-install | & tee c.txt
make clean
make V=1 | & tee m.txt

I get the following error:

  CC       src/mpi/attr/lib_libpmpi_la-attr_delete.lo
In file included from ./src/mpid/ch4/netmod/include/../ofi/ofi_impl.h:10,

make[2]: *** [src/mpi/attr/lib_libpmpi_la-attr_delete.lo] Error 1
make[1]: *** [all-recursive] Error 1
make: *** [all] Error 2

An online search indicates that others are experiencing this error with gcc 11. For example, here https://github.com/JayDDee/cpuminer-opt/issues/313, https://gitlab.com/xonotic/darkplaces/-/issues/363, and https://github.com/relic-toolkit/relic/issues/202.

I have not tried an earlier version of gcc.

Compressed versions of c.txt, m.txt, and config log files are attached.

Thank you, Doug.
