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):

• AMD64 (SysV/ELF, Apple/Mach-O, Mach-O, Win64/PE)
• ARM (EABI/ELF, Apple/Mach-O)
• ARM64 (ARM64/ELF, Apple/Mach-O)
• LoongArch 64 (ELF)
• MIPS (O32/ELF, EABI/ELF)
• MIPS64 (N64/ELF)
• PowerPC (SysV/ELF, EABI/ELF, Apple/Mach-O)
• PowerPC 64 (SysV/ELF, SysV/ELF v2)
• RISC-V 64 (ELF)
• SPARC (SysV/ELF)
• SPARC64 (SysV/ELF)
• x86 (SysV/ELF, Apple/Mach-O, Win32/PE)

Apple/Mach-O means both, the Apple ABI and runtime, while Mach-O means the ObjFW runtime on Mach-O.
