THIS TARBALL IS NOT A FULL DISTRIBUTION. The contents of this tarball is designed to be incorporated into software packages that utilize the AutoOpts option automation package and are intended to be installed on systems that may not have libopts installed. It is redistributable under the terms of either the LGPL (see COPYING.lgpl) or under the terms of the advertising clause free BSD license (see COPYING.mbsd). Usage Instructions for autoconf/automake/libtoolized projects: 1. Install the unrolled tarball into your package source tree, copying ``libopts.m4'' to your autoconf macro directory. In your bootstrap (pre-configure) script, you can do this: rm -rf libopts libopts-* gunzip -c `autoopts-config libsrc` | tar -xvf - mv -f libopts-*.*.* libopts cp -fp libopts/m4/*.m4 m4/. I tend to put my configure auxiliary files in "m4". Whatever directory you choose, if it is not ".", then be sure to tell autoconf about it with: AC_CONFIG_AUX_DIR(m4) This is one macro where you *MUST* remember to *NOT* quote the argument. If you do, automake will get lost. 2. Add the following to your ``configure.ac'' file: LIBOPTS_CHECK or: LIBOPTS_CHECK([relative/path/to/libopts]) This macro will automatically invoke AC_CONFIG_FILES( [relative/path/to/libopts/Makefile] ) The default ``relative/path/to/libopts'' is simply ``libopts''. 3. Add the following to your top level ``Makefile.am'' file: if NEED_LIBOPTS SUBDIRS += $(LIBOPTS_DIR) endif where ``<...>'' can be whatever other files or directories you may need. The SUBDIRS must be properly ordered. *PLEASE NOTE* it is crucial that the SUBDIRS be set under the control of an automake conditional. To work correctly, automake has to know the range of possible values of SUBDIRS. It's a magical name with magical properties. ``NEED_LIBOPTS'' will be correctly set by the ``LIBOPTS_CHECK'' macro, above. 4. Add ``$(LIBOPTS_CFLAGS)'' to relevant compiler flags and ``$(LIBOPTS_LDADD)'' to relevant link options whereever you need them in your build tree. 5. Make sure your object files explicitly depend upon the generated options header file. e.g.: $(prog_OBJECTS) : prog-opts.h prog-opts.h : prog-opts.c prog-opts.c : prog-opts.def autogen prog-opts.def 6. *OPTIONAL* -- If you are creating man pages and texi documentation from the program options, you will need these rules somewhere, too: man_MANS = prog.1 prog.1 : prog-opts.def autogen -Tagman1.tpl -bprog prog-opts.def prog-invoke.texi : prog-opts.def autogen -Taginfo.tpl -bprog-invoke prog-opts.def If your package does not utilize the auto* tools, then you will need to hand craft the rules for building the library.
