Hello All,

in my MELT branch http://gcc.gnu.org/wiki/MiddleEndLispTranslator I need
to compile a C file into a shared object library which can be loaded by
lt_dlopenext

First, I have the impression that the libtool in e.g.
libjava/Makefile.in or libgomp/Makefile.in or libmudflap/Makefile.in is
not the usual one (I mean the Debian/Sid libtool package version
1.5.26-1 for example). I would like to use this tool to compile some
(generated) warm(basilys.c file into a warm-basilys.la in the most
portable way (on Linux/ELF systems I would just use gcc -fPIC -shared
warm-basilys.c -o warm-basilys.so and use the warm-basilys.so shared
library to dlopen).

What is exactly the $(LIBTOOL) in Makefile.in-s (i.e; the @LIBTOOL@ from
some autoconf stuff)?

What is the right way to produce a dynamically loadable "library" which
would be the most portable?

Regards
