[Bug fortran/36309] New: gfrotran and cc1 error

[kih at mail dot nerc-essc dot ac dot uk]

When invoking gfortran to compile some fortran code with C preprocessor
commands in it and using the .F file extension to ensure that the code is
passed though the C pre-processor and error occurs with cc1

The command is:

gfortran -c -g -D_LARGEFILE_SOURCE -D_FILE_OFFSET_BITS=64 -fno-underscoring
-DNOUNIRAS -DNONAMELISTS -I../f77_param filterpl.F

and the error is:

cc1: error: unrecognized command line option "-fno-underscoring"

This error did not occur when using an older gfortran version. cpp won't
recognise "-fno-underscoring" but the old gfortran presumably did not pass
this to cpp whereas the newer version does.

I have a workround which involves invoking cpp seperately on the file excluding
the "-fno-underscoring" and the compiling the output from this but it would be
good to have the old functionality back.

Could you provide some more details, especially about your gfortran version.
The problem is that using:

$ gfortran-4.1 -fno-underscoring aa.F
$ gfortran-4.2 -fno-underscoring aa.F
$ gfortran-4.3 -fno-underscoring aa.F
$ gfortran -fno-underscoring aa.F # 4.4.0 of today

all work. Where did you obtain gfortran and GCC? Which system are you on?

If I call gcc (4.1 to 4.4) with -fno-underscoring then I get the warning:

cc1: warning: command line option "-fno-underscoring" is valid for Fortran but
not for C

Therefore, I wonder whether you are either using an ancient version of gfortran
or that for some reason your new gfortran calls an older version of gcc.

Hi

   Thanks for the response. I was actually installing software on someone
else's system (with their permission) which was an apple machine. I will
check the version of gcc and the rest of the installation. 

Cheers

Kevin

Those look like Apple build (I didn't know they had Fortran in official
builds); did you install them or do they come with the system?

Otherwise, it looks like an issue specific to Apple builds if that's what they
are.

The distribution came from:

so I guess I should take it up with them.

[Bug fortran/36309] gfortran and cc1 error

[pinskia at gcc dot gnu dot org]

------- Comment #7 from pinskia at gcc dot gnu dot org  2008-05-28 08:27 -------
What the issue is that the C compiler was not configured with fortran compiler
so they don't ignore the fortran options but then the fortran compiler was
configured separately.  So this is invalid and really an issue with how cc1 was
built.
