I am facing problem with gfortran-9.2.0 while building sage.
Error building Sage.
The following package(s) may have failed to build (not necessarily
during this run of 'make all-build'):
* package: gfortran-9.2.0
log file: /home/arnald/sage-9.0/logs/pkgs/gfortran-9.2.0.log
build directory: /home/arnald/sage-9.0/local/var/tmp/sage/build/gfortran-9.2.0
The build directory may contain configuration files and other potentially
helpful information. WARNING: if you now run 'make' again, the build
directory will, by default, be deleted. Set the environment variable
SAGE_KEEP_BUILT_SPKGS to 'yes' to prevent this.
Makefile:31: recipe for target 'all-build' failed
make[1]: *** [all-build] Error 1
make[1]: Leaving directory '/home/arnald/sage-9.0'
Makefile:16: recipe for target 'build' failed
make: *** [build] Error 2
I have attached gfortran-9.2.0.log and config.log.
Thanks in advance.
