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.
