Question

I use waf (http://code.google.com/p/waf/) to build a fortran library (which also uses some c-code).

The corresponding wscript looks like this:

 def build(bld):

    bld(
            features = 'fc',
            source   = 'fortran_interface.f90',
            target   = 'fortran_interface.o')
            #install_path = '${PREFIX}/mod')
    #bld.install_files('${PREFIX}/mod','fortran_interface.mod')

    bld(
            features = 'c',
            includes = '../../include',
            source   = 'init_wrapper.c',
            target   = 'init_wrapper.o')

    bld(
            features = 'fc fcstlib',
            use      = 'init_wrapper.o fortran_interface.o',
            target   = 'fortran_interface',
            install_path = '${PREFIX}/lib')

The call waf produces looks like this:

fc: src/fortran/fortran_interface.f90 -> 
    build/src/fortran/fortran_interface.f90.1.o 
    build/fortran_interface.mod

I want to be able to install the .mod file to ${PREFIX}/mod.
I tried install_path which has no effect in this case, or install_files which does not work because a) it doesn’t look inside the build/ directory and b) because it complains before the building if a file is not present.3

As to this thread (http://groups.google.com/group/waf-users/browse_thread/thread/c771a2f4fedd4e3?pli=1) the answer was to create

• a separate build group

  bld.add_group()

• and to use

  bld.srcnode.find_or_declare(<filename>.mod)

to make waf look in the build directory for the .mod file.
