Others
------
Basically, it should run on any POSIX system to which GCC >= 4.6 or a recent
Clang version has been ported. If not, please send an e-mail with a bug report.
If you successfully ran ObjFW on a platform not listed here, please send an
e-mail to js@nil.im so it can be added here!
If you have a platform on which ObjFW does not work, please contact me as well!
Forwarding
==========
As forwarding needs hand-written assembly for each combination of CPU
architecture, executable format and calling convention, it is only available
for the following platforms (except resolveClassMethod: and
resolveInstanceMethod:, which are always available):
* ARM (EABI/ELF, Apple/Mach-O)
* ARM64 (ARM64/ELF, Apple/Mach-O)
* MIPS (O32/ELF, EABI/ELF)
* PowerPC (SysV/ELF, EABI/ELF, Apple/Mach-O)
* SPARC (SysV/ELF)
* SPARC64 (SysV/ELF)
* x86 (SysV/ELF, Apple/Mach-O, Win32/PE)
* x86_64 (SysV/ELF, Apple/Mach-O, Mach-O, Win64/PE)
Apple/Mach-O means both, the Apple ABI and runtime, while Mach-O means the
ObjFW runtime on Mach-O.
