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. -For specific configuration details and testing status, please -refer to the wiki page here: - - http://www.moxielogic.org/wiki/index.php?title=Libffi_3.1 - -At the time of release, the following basic configurations have been -tested: - -|-----------------+------------------+-------------------------| -| Architecture | Operating System | Compiler | -|-----------------+------------------+-------------------------| -| AArch64 (ARM64) | iOS | Clang | -| AArch64 | Linux | GCC | -| Alpha | Linux | GCC | -| Alpha | Tru64 | GCC | -| ARC | Linux | GCC | -| ARM | Linux | GCC | -| ARM | iOS | GCC | -| AVR32 | Linux | GCC | -| Blackfin | uClinux | GCC | -| HPPA | HPUX | GCC | -| IA-64 | Linux | GCC | -| M68K | FreeMiNT | GCC | -| M68K | Linux | GCC | -| M68K | RTEMS | GCC | -| M88K | OpenBSD/mvme88k | GCC | -| Meta | Linux | GCC | -| MicroBlaze | Linux | GCC | -| MIPS | IRIX | GCC | -| MIPS | Linux | GCC | -| MIPS | RTEMS | GCC | -| MIPS64 | Linux | GCC | -| Moxie | Bare metal | GCC | -| Nios II | Linux | GCC | -| PowerPC 32-bit | AIX | IBM XL C | -| PowerPC 64-bit | AIX | IBM XL C | -| PowerPC | AMIGA | GCC | -| PowerPC | Linux | GCC | -| PowerPC | Mac OSX | GCC | -| PowerPC | FreeBSD | GCC | -| PowerPC 64-bit | FreeBSD | GCC | -| PowerPC 64-bit | Linux ELFv1 | GCC | -| PowerPC 64-bit | Linux ELFv2 | GCC | -| S390 | Linux | GCC | -| S390X | Linux | GCC | -| SPARC | Linux | GCC | -| SPARC | Solaris | GCC | -| SPARC | Solaris | Oracle Solaris Studio C | -| SPARC64 | Linux | GCC | -| SPARC64 | FreeBSD | GCC | -| SPARC64 | Solaris | Oracle Solaris Studio C | -| TILE-Gx/TILEPro | Linux | GCC | -| VAX | OpenBSD/vax | GCC | -| X86 | FreeBSD | GCC | -| X86 | GNU HURD | GCC | -| X86 | Interix | GCC | -| X86 | kFreeBSD | GCC | -| X86 | Linux | GCC | -| X86 | Mac OSX | GCC | -| X86 | OpenBSD | GCC | -| X86 | OS/2 | GCC | -| X86 | Solaris | GCC | -| X86 | Solaris | Oracle Solaris Studio C | -| X86 | Windows/Cygwin | GCC | -| X86 | Windows/MingW | GCC | -| X86-64 | FreeBSD | GCC | -| X86-64 | Linux | GCC | -| X86-64 | Linux/x32 | GCC | -| X86-64 | OpenBSD | GCC | -| X86-64 | Solaris | Oracle Solaris Studio C | -| X86-64 | Windows/MingW | GCC | -| Xtensa | Linux | GCC | -|-----------------+------------------+-------------------------| - -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. - -If you're building libffi directly from version control, configure won't -exist yet; run ./autogen.sh first. - -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 CXX=path/to/msvcc.sh LD=link CPP=\"cl -nologo -EP\" - -For 64-bit Windows builds, use CC="path/to/msvcc.sh -m64" and -CXX="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 ftp.gnu.org:/pub/gnu/make . - -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 git log for details at http://github.com/atgreen/libffi. - -3.1 May-19-14 - Add AArch64 (ARM64) iOS support. - Add Nios II support. - Add m88k and DEC VAX support. - Add support for stdcall, thiscall, and fastcall on non-Windows - 32-bit x86 targets such as Linux. - Various Android, MIPS N32, x86, FreeBSD and UltraSPARC IIi - fixes. - Make the testsuite more robust: eliminate several spurious - failures, and respect the $CC and $CXX environment variables. - Archive off the manually maintained ChangeLog in favor of git - log. - -3.0.13 Mar-17-13 - Add Meta support. - Add missing Moxie bits. - Fix stack alignment bug on 32-bit x86. - Build fix for m68000 targets. - Build fix for soft-float Power targets. - Fix the install dir location for some platforms when building - with GCC (OS X, Solaris). - Fix Cygwin regression. - -3.0.12 Feb-11-13 - Add Moxie support. - Add AArch64 support. - Add Blackfin support. - Add TILE-Gx/TILEPro support. - Add MicroBlaze support. - Add Xtensa support. - Add support for PaX enabled kernels with MPROTECT. - Add support for native vendor compilers on - Solaris and AIX. - Work around LLVM/GCC interoperability issue on x86_64. - -3.0.11 Apr-11-12 - Lots of build fixes. - 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. - -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.
