[Distutils] Hack for runtime_library_dir_option

[Berthold Höllmann]

Hello,

Using scipy distutils under Solaris I stumbled over a problem in
distutils unixccompiler. In runtime_library_dir_option the C compiler
name is used to determine whether to a use "-Wl,-R" or "-R". I use the
Sun Fortran compiler together with gcc. Now when linking an extension
module that uses "runtime_library_dirs" and the fortran compiler for
linking I get an error message because of the usage of "-Wl.-R"
instead of "-R". I rewrote the routine a little bit:

    def runtime_library_dir_option(self, dir):
        # XXX Hackish, at the very least.  See Python bug #445902:
        # http://sourceforge.net/tracker/index.php
        #   ?func=detail&aid=445902&group_id=5470&atid=105470
        # Linkers on different platforms need different options to
        # specify that directories need to be added to the list of
        # directories searched for dependencies when a dynamic library
        # is sought.  GCC has to be told to pass the -R option through
        # to the linker, whereas other compilers just know this.
        # Other compilers may need something slightly different.  At
        # this time, there's no way to determine this information from
        # the configuration data stored in the Python installation, so
        # we use this hack.
        linker = self.linker_so
        if sys.platform[:6] == "darwin":
            # MacOSX's linker doesn't understand the -R flag at all
            return "-L" + dir
        elif sys.platform[:5] == "hp-ux":
            return "+s -L" + dir
        elif linker[:3] == "gcc" or linker[:3] == "g++" or linker[:3] == "g77":
          return "-Wl,-R" + dir
        else:
            return "-R" + dir

and now it works for me. Shall I issue a but report on this or is my
usage to exotic?

Kind regards
