Error when building mpich with gcc 12.2 : multiple definition of `HYD_pmcd_pmip'

[thisisalloneword]

Perhaps some mpich bug as described here:

818280 – sys-cluster/mpich-3.0.4 emerge failed: multiple definition of `HYD_pmcd_pmip'

bugs.gentoo.org

Here is the exact error below.

Strangely I do not get this error when using Intel OneAPI 2022.

I have these environement flags set:

FFLAGS=-m64 -w -fallow-argument-mismatch -O2
FCGLAGS=-m64

Just an update I resolved this issue by using mpich-4.1.2 . I also had to edit configure.wrf with:

CPPFLAGS=-I/gpfs/users/home/wrf/Build_WRF/LIBRARIES/mpich/include .......

Without that I was getting build errors about missing mpif.h file.

Not sure this is all "kosher" with 4.3/4.4 ? Or possibly I am following outdated build instructions? I am using these steps:

Compiling WRF

 

[jhodges]

I was able to fix the MPICH 3.0.4 compilation with GCC12 by adding "-fcommon" to the CPPFLAGS variable.

Can confirm that adding "-fcommon" to the CPPFLAGS variable and setting these variables fixed the issue:

FFLAGS=-m64 -w -fallow-argument-mismatch -O2
FCGLAGS=-m64

 

[nos_1988]

I confirmed that adding -fcommon to the CPPFLAGS works
