Check the libffi web page for +updates: . + + +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. +For specific configuration details and testing status, please +refer to the wiki page here: + + http://www.moxielogic.org/wiki/index.php?title=Libffi_3.0.11 + +At the time of release, the following basic configurations have been +tested: + +|-----------------+------------------| +| Architecture | Operating System | +|-----------------+------------------| +| Alpha | Linux | +| Alpha | Tru64 | +| ARM | Linux | +| ARM | iOS | +| AVR32 | Linux | +| Blackfin | uClinux | +| HPPA | HPUX | +| IA-64 | Linux | +| M68K | FreeMiNT | +| M68K | RTEMS | +| MIPS | IRIX | +| MIPS | Linux | +| MIPS | RTEMS | +| MIPS64 | Linux | +| PowerPC | AMIGA | +| PowerPC | Linux | +| PowerPC | Mac OSX | +| PowerPC | FreeBSD | +| PowerPC64 | Linux | +| S390 | Linux | +| S390X | Linux | +| SPARC | Linux | +| SPARC | Solaris | +| SPARC64 | Linux | +| SPARC64 | FreeBSD | +| TILE-Gx/TILEPro | Linux | +| X86 | FreeBSD | +| X86 | Interix | +| X86 | kFreeBSD | +| X86 | Linux | +| X86 | Mac OSX | +| X86 | OpenBSD | +| X86 | OS/2 | +| X86 | Solaris | +| X86 | Windows/Cygwin | +| X86 | Windows/MingW | +| X86-64 | FreeBSD | +| X86-64 | Linux | +| X86-64 | Linux/x32 | +| X86-64 | OpenBSD | +| X86-64 | Windows/MingW | +|-----------------+------------------| + +Please send additional platform test results to +libffi-discuss@sourceware.org and feel free to update the wiki page +above. + +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". + + +History +======= + +See the ChangeLog files for details. + +3.0.12 XXX-XX-XX + Add Blackfin support. + Add TILE-Gx/TILEPro support. + +3.0.11 Apr-11-12 + Lots of build fixes. + Add Amiga newer MacOS support. + Add support for variadic functions (ffi_prep_cif_var). + Add Linux/x32 support. + Add thiscall, fastcall and MSVC cdecl support on Windows. + Add Amiga and newer MacOS support. + Add m68k FreeMiNT support. + Integration with iOS' xcode build tools. + Fix Octeon and MC68881 support. + Fix code pessimizations. + Lots of build fixes. + +3.0.10 Aug-23-11 + Add support for Apple's iOS. + Add support for ARM VFP ABI. + Add RTEMS support for MIPS and M68K. + Fix instruction cache clearing problems on + ARM and SPARC. + Fix the N64 build on mips-sgi-irix6.5. + Enable builds with Microsoft's compiler. + Enable x86 builds with Oracle's Solaris compiler. + Fix support for calling code compiled with Oracle's Sparc + Solaris compiler. + Testsuite fixes for Tru64 Unix. + Additional platform support. + +3.0.9 Dec-31-09 + Add AVR32 and win64 ports.
