libffi-3.0.12 was released on XXXXXXX. 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.
|
||||||
|
|
||||||
|
|
||||||
|

||||||
|
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 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.)
|
||||||
|
|
||||||
|
For iOS builds, the 'libffi.xcodeproj' Xcode project is available.
|
||||||
|
|
||||||
|
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".
