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"

SHTOOL-VERSION.TMP(1) GNU Portable Shell Tool SHTOOL-VERSION.TMP(1)NAME
shtool-version - GNU shtool maintain version information file
SYNOPSIS
shtool version [-l|--language lang] [-n|--name name] [-p|--prefix prefix] [-s|--set version] [-e|--edit] [-i|--increase knob] [-d|--display
type] file
DESCRIPTION
This command displays and maintains version information in file.
The version is always described with a triple <version,revision,level> and is represented by a string which always matches the regular
expression ""[0-9]+.[0-9]+[sabp.][0-9]+"".
The hexadecimal format for a version "v.rtl" is "VVRRTLL" where "VV" and "RR" directly correspond to "v" and "r", "T" encodes the level
type as 9, 2, 1, 0 (representing "s", "p"/".", "b", "a" in this order) and "LL" is either directly corresponding to "l" or set to 99 if
level type is "s".
OPTIONS
The following command line options are available.
-v, --verbose
Print verbose information during processing.
-l, --language lang
Choose format of version file file. lang=""txt"", ANSI C (lang="c"), M4 (lang="m4"), Perl (lang="perl") or Python (lang="python").
Default is "txt".
-n, --name name
Name the program the version is maintained for. Default is "unknown".
-p, --prefix prefix =item -s, --set version
Set the version to version.
-e, --edit
Interactively enter a new version.
-i, --increase knob
When option ``-i'' is used, the current version in file is updated by increasing one element of the version where knob can be one of
the following: ``"v"'' for increasing the version by 1 (and resetting revision and level to 0), ``"r"'' for increasing the revision by
1 (and resetting level to 0) or ``"l"'' for increasing the level by 1.
-d, --display type
Control the display type: ""short"" for a short version display, ""long"" for a longer version display, ""hex"" for a hexadecimal
display of the version and ""libtool"" for a format suitable for use with GNU libtool.
EXAMPLE
# shell script
shtool version -l c -n FooBar -p foobar -s 1.2b3 version.c
# configure.in
V=`shtool version -l c -d long version.c`
echo "Configuring FooBar, Version $V"
HISTORY
The GNU shtool version command was originally written by Ralf S. Engelschall <rse@engelschall.com> in 1994 for OSSP eperl. It was later
rewritten from scratch for inclusion into GNU shtool.
