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.
