Description
Describe the issue:
When I use flang to compile RTTOV-11.3 with f2py, it will report a compilation ERROR: numpy.distutils.fcompiler.CompilerNotFound. But before the ERROR, it also prints: Found executable /path/to/compiler/bin/flang.
Reproduce the code example:
export FC=flang
f2py -c --help-fcompilerError message:
In "Fortran compilers found" part, it will print:
--fcompiler=gnu95 GNU Fortran 95 compiler (12.0.0)Actually, "12.0.0" is flang compiler's version, not GNU95's. So if I specify fcompiler as "flang", numpy will raise CompilerNotFound EXCEPTION. So I have to specify fcompiler as "gnu95" to continue to compile RTTOV.
Runtime information:
Found executable /path/to/compiler/bin/flang
