SHTOOL-SLO.TMP(1)	    GNU	Portable Shell Tool	     SHTOOL-SLO.TMP(1)

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.
