On a  x86_64-redhat-linux-gnu computer, with Fedora 42 and a beta gcc,  
  I try to&nbsp;
build&nbsp; the&nbsp;mpich-4.3.1&nbsp;(stable release), but there is  
the errror:
&nbsp;
   make[2]: Entering directory '/home/bigpack/mpich-paq/mpich-4.3.1/BUILD'
   &nbsp; GEN&nbsp; &nbsp; &nbsp; lib/libmpifort.la

file or directory

   make[1]: Leaving directory '/home/bigpack/mpich-paq/mpich-4.3.1/BUILD'
   make: *** [Makefile:10489: all] Error 2

I attach&nbsp;the config.log, configure.eco, and make.eco files.

Please, any help or suggestions for fixing this?

Thanks in advance.

Regards.
Jorge D'Elia.
