But as you said, It will be great if we could compile a binary that runs on both OSX ARM and OSX Intel.
I think we could rebuild ffmpeg on ARM based Mac to have an executable compatible for only ARM Mac.
Thank you for providing this detailed information. Tl dr - None of the existing binaries will run on OSX ARM, but there's a near 100% likelihood that there will be a single binary that runs on both OSX ARM and OSX Intel, but these can't be built until Apple ships the necessary toolchain. For an example of such a system, look at the WINE project which attempts to make Windows executables run on Unix systems.
For the next several years we'll have fat MACH-O binaries that include both ARM and Intel code and eventually they'll remove support for the Intel computers.īut there's no chance that the Linux binary will run on Mac without something to provide ELF support and mapping the Linux Kernel API calls to OSX API calls. My expectation is that they'll do the same for ARM. At some point they deprecated the PowerPC platform and xcode stopped building the PowerPC support. Apple used the fat binary support back when they switched from PowerPC to Intel by having developers build executable files that contained executables for both PowerPC and Intel processors. Linux uses the ELF executable format whereas iOS and OSX use MACH-O executable format with fat binary support. The latter 2 don't matter as much with these static builds, though I think the linux "static" builds still link to the local glibc. Each OS has its own executable file format, Kernel API, library format, linking system, etc. There's more to this than just processor architecture.
