Hello, Currently there is no guideline regarding fortran 90 .mod, it seems to me that one is needed. These files are generated by gfortran when building a module. These are text files, but not intended to be read by humans. They are architecture dependent. When compiling some code that uses the module, the .mod has to be found in the include path (for example in a directory specified by -I). Where should the .mod be installed? I propose %_libdir %_libdir/include %_libdir/modules %_libdir/mod %_libdir/f90 %_includedir/%_lib %_includedir/%_lib/modules %_includedir/%_lib/mod %_includedir/%_lib/f90 (f90 may also be replaced by another meaningfull subdirectory name). This directory could be called %_fmoddir And add -I%_fmoddir in FFLAGS when compiling some code that requires the module. The optimal situation would be to have %_fmoddir defined in rpm macros and -I%_fmoddir added to default FFLAGS. So my first question is what is your advice about fortran modules directories? My second is, in case it is meaningful, what about my proposal regarding rpm macros? -- Pat -- Fedora-packaging mailing list Fedora-packaging@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-packaging
