shtool slo [-p|--prefix str] -- -Ldir -llib [-Ldir -llib ...]
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.
The following command line options are available.
-p, --prefix str
Directory where libraries are searched in.
Library to search for.
eval `shtool slo $LINK_STD`
LINK_DSO="$SLO_DIRS_OBJ $SLO_LIBS_OBJ $SLO_DIRS_PIC $SLO_LIBS_PIC"
The GNU shtool slo command was originally written by Ralf S.
Engelschall <firstname.lastname@example.org> in 1998 for Apache. It was later
taken over into GNU shtool.
