I am trying to compile a model by PGF90. If I use the compiling command:
/usr/local/pgi/linux86-64/6.1/bin/pgf90 -Mpreprocess -fast -r8 -i8 -mcmodel=medium -Mlarge_arrays -c -Dtype=1 -Dtracer=0 -Dadvection_method=0 -Dbuoy=0 -Dgeostrophy=0 -Dfriction=0 *.f
The error would be:PGF90-S-0021-Label field of continuation line is not blank
If I use the compiling command by extra -Mcpp: /usr/local/pgi/linux86-64/6.1/bin/pgf90 -Mpreprocess -fast -r8 -i8 -mcmodel=medium -Mlarge_arrays -Mcpp -c -Dtype=1 -Dtracer=0 -Dadvection_method=0 -Dbuoy=0 -Dgeostrophy=0 -Dfriction=0 *.f
The error would be:ar: ‘*.o’: No such file. That is , there is no object file existing.
So My question is what flag I should add to the compiling line so that both two errors get solved at one time?
Thank you.
Hi tingting,
“-Mcpp” stops after the preprocessing step and is why your not seeing the error message or getting the “.o” files.
As for error #21 which occurs during compilation, perhaps your using free form? If so, add “-Mfree” to your compilations. If you’re using fixed form, then your post-process file is missing spaces before your continuation line.
As as side note, the extensions “.f” and “.F” tells the compiler you’re using fixed form while “.f90” and “.F90” means free form. Also, if you use an upper case “F” in your file extension, then the file will be preprocessed by default.
Hi, Mat,
Thank you for your fast respond.
I went back and checked the form of the model. The extensions of the fortran file is “.f”, but the code is actually not fixed completedly. I don’t know how the writer of model make it work. But I follow your suggestion and add -Mfree to the compiling. Then the new problem comes out. The pgf90 free form doesn’t recognize comment line beginning with capital C (pgf90 uses !) and the signal of continuation lines (pgf90 uses & at the end of line) in fixed form. Do you think I have to change the code one by one? Or do you think there is a better and easier way to get it work?
Here is the error information.

Thanks a lot!

Hi tingting,
Unfortunately, you can’t mix forms within the same source file. However, instead of using “-Mfree”, try renaming those source file that are in free form to use the “.F90” extension. This way you might need to fix fewer files.
Hope this helps,
Mat
