+New in 1.2e: CVS version; 1.2f: 1999-03-15, Libtool team:
* libtool will correctly link uninstalled libraries into programs
and prefer uninstalled libraries to installed ones
-* Library paths that are in the system search path are no longer hardcoded.
+* Library paths that are in the system default run-time search path
+ are no longer hardcoded into executables.
* New fast installation mode, which links the final executable
in order to avoid relinking during installation.
Programs in the build-tree are relinked when executed.
* check whether the version of libtool.m4 is compatible
with ltconfig/ltmain.sh
-* check whether the "file" command is available
-
* Inter-library dependencies should be fully tracked by libtool
and need to work for ltlibraries too. This requires looking up
installed libtool libraries for transparent support.
* Documentation:
-- libltdl documentation needs to be completed.

Notes:
-
- "ok" means "all tests passed".
-
- "NS" means "Not Shared", but OK for static libraries
-
-- "static" means that the system doesn't support shared libs,
- but libtool can build static libraries.
-
-* Some versions of GCC's collect2 linker program cannot link trivial
- static binaries on AIX 3. For these configurations, libtool's
- `-all-static' flag has no effect.
-
-** Note that R4.12TMU01 is the C2 release of DG/UX which corresponds to
- R4.11MU04 in the base release. These should be equivalent as far as
- libtool is concerned, but only R4.12TMU01 has actually been tested.
@example
burger$ @kbd{libtool gcc -g -O -o test test.o /usr/local/lib/libhello.la}
-gcc -g -O -o @value{objdir}/test test.o -Wl,--rpath -Wl,/usr/local/lib /usr/local/lib/libhello.la -lm
+gcc -g -O -o @value{objdir}/test test.o -Wl,--rpath
+-Wl,/usr/local/lib /usr/local/lib/libhello.a -lm
creating test
burger$
@end example
@item -dlopen @var{file}
Same as @samp{-dlpreopen @var{file}}, if native dlopening is not

Libtool provides a small library, called @file{libltdl}, that aims at

It consists of a header-file and a small C source file that can be

Libltdl supports currently the following dynamic linking mechanims:

+glibc 2.1. On the other hand, @samp{RTLD_NOW} was reported to introduce

@node Modules for libltdl
@section Creating modules that can be @code{dlopen}ed
-empty
+Libtool modules are like normal libtool libraries with a few exceptions:
+
+You have to link the module with libtool's @samp{-module} switch,
+and you should link any program that is intended to dlopen the module with
+@samp{-dlopen modulename.la} so that libtool can dlpreopen the module
+on platforms which don't support dlopening. If the module depends on any
+other libraries, make sure you specify them either when you link the module
+or when you link programs that dlopen it.
+If you want to disable @pxref{Versioning} for a specific module
+you should link it with the @samp{-avoid-version} switch.
+Note that libtool modules don't need to have a "lib" prefix.
+However, automake 1.4 or higher is required to build such modules.
+
+Usually a set of modules provide the same interface, i.e, exports the same
+symbols, so that a program can dlopen them without having to know more
+about their internals.
+In order to avoid symbol conflicts all exported symbols must be prefixed
+with "modulename_LTX_" (@samp{modulename} is the name of the module).
+Internal symbols must be named in such a way that they won't conflict
+with other modules, for example, by prefixing them with "_modulename_".
+Although some platforms support having the same symbols defined more than
+once it is generally not portable and it makes it impossible to dlpreopen
+such modules. libltdl will automatically cut the prefix off to get
+the real name of the symbol. Additionally, it supports modules which
+don't use a prefix so that you can also dlopen non-libtool modules.
+
+@file{foo1.c} gives an example of a portable libtool module.
+Exported symbols are prefixed with "foo1_LTX_", internal symbols
+with "_foo1_". Aliases are defined at the beginning so that the code
+is more readable.
+
+@example
+/* aliases for the exported symbols */
+#define foo foo1_LTX_foo
+#define bar foo1_LTX_bar
+
+/* a global variable definition */
+int bar = 1;
+
+/* a private function */
+int _foo1_helper() @{
+ return bar;
+@}
+
+/* an exported function */
+int foo() @{
+ return _foo_helper();
+@}
+@end example
+
+@noindent
+The @file{Makefile.am} contains the necessary rules to build the
+module @file{foo1.la}:
+
+@example
+...
+lib_LTLIBRARIES = foo1.la
+
+foo1_la_SOURCES = foo1.c
+foo1_la_LDFLAGS = -module
+...
+@end example
@node Distributing libltdl
@section How to distribute libltdl with your package
-empty
+Even though libltdl is installed together with libtool, you may wish to
+include libltdl in the distribution of your package, for the convenience
+of users of your package that don't have libtool or libltdl installed.
+In this case, you may decide which flavor of libltdl you want to use: a
+convenience library or an installable libtool library.
+
+One advantage of the convenience library is that it is not installed, so
+the fact that you use libltdl will not be apparent to the user, and it
+will not overwrite a pre-installed version of libltdl a user might have.
+On the other hand, if you want to upgrade libltdl for any reason
+(e.g. a bugfix) you'll have to recompile your package instead of just
+replacing an installed version of libltdl.
+However, if your programs or libraries are linked with other libraries
+that use such a pre-installed version of libltdl, you may get linker
+errors or run-time crashes. Another problem is that you cannot link the
+convenience library into more than one libtool library, then link a
+single program with these libraries, because you may get duplicate
+symbols. In general you can safely use the convenience library in programs
+which don't depend on other libraries that might use libltdl too.
+In order to enable this flavor of libltdl, you should add the
+line @samp{AC_LIBLTDL_CONVENIENCE} to your @file{configure.in},
+@emph{after} @samp{AM_PROG_LIBTOOL}.
+
+In order to select the installable version of libltdl, you should add a
+call of the macro @samp{AC_LIBLTDL_INSTALLABLE} to your
+@file{configure.in} @emph{after} @samp{AM_PROG_LIBTOOL}. This macro
+will check whether libltdl is already installed and, if not, request the
+libltdl embedded in your package to be built and installed. Note,
+however, that no version checking is performed. The user may override
+the test and determine that the libltdl embedded must be installed,
+regardless of the existence of another version, using the configure
+switch @samp{--enable-ltdl-install}.
+
+In order to embed libltdl into your package, just add @samp{--ltdl} to
+the @code{libtoolize} command line. It will copy the libltdl sources
+to a subdirectory @samp{libltdl} in your package.
+Both macros accept an optional argument to specify the location
+of the @samp{libltdl} directory. By the default both macros assume that it
+is @samp{$@{top_builddir@}/libltdl}.
+
+Whatever macro you use, it is up to you to ensure that your
+@file{configure.in} will configure libltdl, using
+@samp{AC_CONFIG_SUBDIRS}, and that your @file{Makefile}s will start
+sub-makes within libltdl's directory, using automake's @var{SUBDIRS},
+for example. Both macros define the shell variable @var{LIBLTDL} to
+the link flag that you should use to link with libltdl. It is up to you
+to use @samp{AC_SUBST} to ensure that this variable will be available in
+@file{Makefile}s.
+
+If you're using the convenience libltdl, it will be the pathname for the
+convenience version of libltdl, starting with @samp{$@{top_builddir@}/}.
+Otherwise, if an installed version of libltdl is found, @var{LIBLTDL}
+will be set to @samp{-lltdl}. If an installable version of libltdl must
+be built, its pathname, starting with @samp{$@{top_builddir@}/}, will be
+stored in @var{LIBLTDL}. So, when you want to link a program with
+libltdl, just link it with @samp{$(LIBLTDL)}.
+
+You should probably also add @samp{AC_LIBTOOL_DLOPEN} to your
+@file{configure.in} @emph{before} @samp{AM_PROG_LIBTOOL}, otherwise
+libtool will assume no dlopening mechanism is supported, and revert to
+dlpreopening, which is probably not what you want.
+
+Avoid using the @code{-all-static} switch when linking programs with
+libltdl; this will not work on all plaforms, because the dlopening
+functions may not be available for static linking.
+
+The following example shows you how to embed the convenience libltdl
+in your package. In order to use the installable variant just replace
+AC_LIBLTDL_CONVENIENCE with AC_LIBLTDL_INSTALLABLE. We assume that
+libltdl was embedded using @samp{libtoolize --ltdl}.
+
+configure.in:
+@example
+...
+dnl Check for dlopen support
+AC_LIBTOOL_DLOPEN
+dnl Configure libtool
+AM_PROG_LIBTOOL
+dnl Enable building of the convenience library and set LIBLTDL accordingly
+AC_LIBLTDL_CONVENIENCE
+dnl Substitute LIBLTDL in the Makefiles
+AC_SUBST(LIBLTDL)
+dnl Configure libltdl
+AC_CONFIG_SUBDIRS(libltdl)
+...
+@end example
+
+Makefile.am:
+@example
+...
+SUBDIRS = libltdl
+
+myprog_LDFLAGS = -export-dynamic
+# The quotes around -dlopen below fool automake into accepting it
+myprog_LDADD = $(LIBLTDL) "-dlopen" self "-dlopen" libfoo.la
+myprog_DEPENDENCIES = $(LIBLTDL) libfoo.la
