NAME

       shtool-slo - GNU shtool separate linker options by library class

SYNOPSIS

       shtool slo [-p|--prefix str] -- -Ldir -llib [-Ldir -llib ...]

DESCRIPTION

       This command separates the linker options ``-L'' and ``-l'' by library class. It's argument line can
       actually be an arbitrary command line where those options are contained. slo parses these two options
       only and ignores the remaining contents. The result is a trivial shell script on "stdout" which defines
       six variables containing the ``-L'' and ``-l'' options sorted by class:

       ``"SLO_DIRS_OBJ"'' and ``"SLO_LIBS_OBJ"'' contains the ``-L'' and ``-l'' options of static libraries,
       ``"SLO_DIRS_PIC"'' and ``"SLO_LIBS_PIC"'' contains the ``-L'' and ``-l'' options of static libraries
       containing PIC ("Position Independent Code") and ``"SLO_DIRS_DSO"'' and ``"SLO_LIBS_DSO"'' contains the
       ``-L'' and ``-l'' options of shared libraries. The -p option can be used to change the default variable
       prefix from ""SLO_"" to str.

       The intent of this separation is to provide a way between static and shared libraries which is important
       if one wants to link custom DSOs against libraries, because not all platforms all one to link these DSOs
       against shared libraries. So one first has to separate out the shared libraries and link the DSO only
       against the static libraries.  One can use this command also to just sort the options.

OPTIONS

       The following command line options are available.

       -p, --prefix str
               FIXME

       -Ldir
           Directory where libraries are searched in.

       -llib
           Library to search for.

EXAMPLE

        #   configure.in
        LINK_STD="$LDFLAGS $LIBS"
        eval `shtool slo $LINK_STD`
        LINK_DSO="$SLO_DIRS_OBJ $SLO_LIBS_OBJ $SLO_DIRS_PIC $SLO_LIBS_PIC"
          :

HISTORY

       The GNU shtool slo command was originally written by Ralf S.  Engelschall <rse@engelschall.com> in 1998
       for Apache.  It was later taken over into GNU shtool.
