Status
======
libffi-3.0.10 was released on XXXXXXXXXX, 2010. Check the libffi web
page for updates: <URL:http://sourceware.org/libffi/>.
What is libffi?
===============
Compilers for high level languages generate code that follow certain
conventions. These conventions are necessary, in part, for separate
compilation to work. One such convention is the "calling
convention". The "calling convention" is essentially a set of
assumptions made by the compiler about where function arguments will
be found on entry to a function. A "calling convention" also specifies
where the return value for a function is found.
Some programs may not know at the time of compilation what arguments
are to be passed to a function. For instance, an interpreter may be
told at run-time about the number and types of arguments used to call
a given function. Libffi can be used in such programs to provide a
bridge from the interpreter program to compiled code.
The libffi library provides a portable, high level programming
interface to various calling conventions. This allows a programmer to
call any function specified by a call interface description at run
time.
FFI stands for Foreign Function Interface. A foreign function
interface is the popular name for the interface that allows code
written in one language to call code written in another language. The
libffi library really only provides the lowest, machine dependent
layer of a fully featured foreign function interface. A layer must
exist above libffi that handles type conversions for values passed
between the two languages.
Supported Platforms
===================
Libffi has been ported to many different platforms.

Installing libffi
=================
First you must configure the distribution for your particular
system. Go to the directory you wish to build libffi in and run the
"configure" program found in the root directory of the libffi source
distribution.
You may want to tell configure where to install the libffi library and
header files. To do that, use the --prefix configure switch. Libffi
will install under /usr/local by default.
If you want to enable extra run-time debugging checks use the the
--enable-debug configure switch. This is useful when your program dies
mysteriously while using libffi.
Another useful configure switch is --enable-purify-safety. Using this
will add some extra code which will suppress certain warnings when you
are using Purify with libffi. Only use this switch when using
Purify, as it will slow down the library.
It's also possible to build libffi on Windows platforms with
Microsoft's Visual C++ compiler. In this case, use the msvcc.sh
wrapper script during configuration like so:
path/to/configure --enable-shared --enable-static \
CC=path/to/msvcc.sh LD=link \
CPP=\"cl -nologo -EP\"
Configure has many other options. Use "configure --help" to see them all.
Once configure has finished, type "make". Note that you must be using
GNU make. You can ftp GNU make from prep.ai.mit.edu:/pub/gnu.
To ensure that libffi is working as advertised, type "make check".
This will require that you have DejaGNU installed.
To install the library and header files, type "make install".

Authors & Credits
=================
libffi was originally written by Anthony Green <green@redhat.com>.
The developers of the GNU Compiler Collection project have made
innumerable valuable contributions. See the ChangeLog file for
details.
Some of the ideas behind libffi were inspired by Gianni Mariani's free
gencall library for Silicon Graphics machines.
The closure mechanism was designed and implemented by Kresten Krab
Thorup.
Major processor architecture ports were contributed by the following
developers:
alpha Richard Henderson
arm Raffaele Sena
cris Simon Posnjak, Hans-Peter Nilsson
frv Anthony Green
ia64 Hans Boehm
m32r Kazuhiro Inaoka
m68k Andreas Schwab
mips Anthony Green, Casey Marshall
mips64 David Daney
pa Randolph Chung, Dave Anglin, Andreas Tobler
powerpc Geoffrey Keating, Andreas Tobler,
David Edelsohn, John Hornkvist
powerpc64 Jakub Jelinek
s390 Gerhard Tonn, Ulrich Weigand
sh Kaz Kojima
sh64 Kaz Kojima
sparc Anthony Green, Gordon Irlam
x86 Anthony Green, Jon Beniston
x86-64 Bo Thorsen
Jesper Skov and Andrew Haley both did more than their fair share of
stepping through the code and tracking down bugs.
Thanks also to Tom Tromey for bug fixes, documentation and
configuration help.
Thanks to Jim Blandy, who provided some useful feedback on the libffi
interface.
Andreas Tobler has done a tremendous amount of work on the testsuite.
Alex Oliva solved the executable page problem for SElinux.
The list above is almost certainly incomplete and inaccurate. I'm
happy to make corrections or additions upon request.
If you have a problem, or have found a bug, please send a note to
green@redhat.com.

@@ -113,13 +114,9 @@ It's also possible to build libffi on Windows platforms with
Microsoft's Visual C++ compiler. In this case, use the msvcc.sh
wrapper script during configuration like so:
path/to/configure CC=path/to/msvcc.sh LD=link CPP=\"cl -nologo -EP\"
For 64-bit Windows builds, use CC="path/to/msvcc.sh -m64".
You may also need to specify --build appropriately. When building with MSVC
under a MingW environment, you may need to remove the line in configure
that sets 'fix_srcfile_path' to a 'cygpath' command. ('cygpath' is not
present in MingW, and is not required when using MingW-style paths.)
path/to/configure --enable-shared --enable-static \
CC=path/to/msvcc.sh LD=link \
CPP=\"cl -nologo -EP\"
Configure has many other options. Use "configure --help" to see them all.
