libcharset/INTEGRATE

Integration of this library into your package:

* Copy the lib/ sourcefiles (localcharset.c, config.charset, ref-add.sin,
  ref-del.sin) and the include file (include/localcharset.h) into your
  package.

* Add the m4/ files (codeset.m4, fcntl_h.m4, glibc21.m4) to your aclocal.m4
  file or, if you are using automake, to your m4/ directory.

* Add the following lines to your configure.ac file:

    AC_CANONICAL_HOST
    AM_LANGINFO_CODESET
    gl_FCNTL_O_FLAGS
    jm_GLIBC21
    AC_CHECK_HEADERS(stddef.h stdlib.h string.h)

  and make sure that it sets and AC_SUBSTs the PACKAGE variable.

* If you are not using automake, add rules to your Makefile.in:

  - Augment target "all" by
      localcharset.o charset.alias ref-add.sed ref-del.sed
    with special rules for the last three:

    charset.alias: $(srcdir)/config.charset
	$(SHELL) $(srcdir)/config.charset '@host@' > t-$@
	mv t-$@ $@

    ref-add.sed : $(srcdir)/ref-add.sin
	sed -e '/^#/d' -e 's/@''PACKAGE''@/@PACKAGE@/g' $(srcdir)/ref-add.sin > t-$@
	mv t-$@ $@

    ref-del.sed : $(srcdir)/ref-del.sin
	sed -e '/^#/d' -e 's/@''PACKAGE''@/@PACKAGE@/g' $(srcdir)/ref-del.sin > t-$@
	mv t-$@ $@

  - Augment target "install" by

	if test @GLIBC21@ = no; then \
	  case '@host_os@' in \
	    darwin[56]*) \
	      need_charset_alias=true ;; \
	    darwin* | cygwin* | mingw* | pw32* | cegcc*) \
	      need_charset_alias=false ;; \
	    *) \
	      need_charset_alias=true ;; \
	  esac ; \
	else \
	  need_charset_alias=false ; \
	fi ; \
	if $$need_charset_alias; then \
	  $(mkinstalldirs) $(DESTDIR)$(libdir) ; \
	fi ; \
	if test -f $(DESTDIR)$(libdir)/charset.alias; then \
	  sed -f ref-add.sed $(DESTDIR)$(libdir)/charset.alias > $(DESTDIR)$(libdir)/t-charset.alias; \
	  $(INSTALL_DATA) $(DESTDIR)$(libdir)/t-charset.alias $(DESTDIR)$(libdir)/charset.alias; \
	  rm -f $(DESTDIR)$(libdir)/t-charset.alias; \
	else \
	  if $$need_charset_alias; then \
	    sed -f ref-add.sed charset.alias > $(DESTDIR)$(libdir)/t-charset.alias; \
	    $(INSTALL_DATA) $(DESTDIR)$(libdir)/t-charset.alias $(DESTDIR)$(libdir)/charset.alias; \
	    rm -f $(DESTDIR)$(libdir)/t-charset.alias; \
	  fi; \
	fi

  - Augment target "installdirs" by

	if test @GLIBC21@ = no; then \
	  case '@host_os@' in \
	    darwin[56]*) \
	      need_charset_alias=true ;; \
	    darwin* | cygwin* | mingw* | pw32* | cegcc*) \
	      need_charset_alias=false ;; \
	    *) \
	      need_charset_alias=true ;; \
	  esac ; \
	else \
	  need_charset_alias=false ; \
	fi ; \
	if $$need_charset_alias; then \
	  $(mkinstalldirs) $(DESTDIR)$(libdir) ; \
	fi ; \

  - Augment target "uninstall" by

	if test -f $(DESTDIR)$(libdir)/charset.alias; then \
	  sed -f ref-del.sed $(DESTDIR)$(libdir)/charset.alias > $(DESTDIR)$(libdir)/t-charset.alias; \
	  if grep '^# Packages using this file: $$' $(DESTDIR)$(libdir)/t-charset.alias > /dev/null; then \
	    rm -f $(DESTDIR)$(libdir)/charset.alias; \
	  else \
	    $(INSTALL_DATA) $(DESTDIR)$(libdir)/t-charset.alias $(DESTDIR)$(libdir)/charset.alias; \
	  fi; \
	  rm -f $(DESTDIR)$(libdir)/t-charset.alias; \
	fi

    - Augment target "clean" by

	rm -f charset.alias ref-add.sed ref-del.sed

* If you are using automake, add rules to your Makefile.am:

  - Augment the main *_SOURCES variable by

        localcharset.h localcharset.c

  - Augment EXTRA_DIST by

        config.charset ref-add.sin ref-del.sin

  - Augment target "all-local" by

        charset.alias ref-add.sed ref-del.sed

  - Add the lines:

charset_alias = $(DESTDIR)$(libdir)/charset.alias
charset_tmp = $(DESTDIR)$(libdir)/charset.tmp
install-exec-local: all-local
	test @GLIBC21@ != no || $(mkinstalldirs) $(DESTDIR)$(libdir)
