/gcc/config/aarch64/aarch64-builtins.c:1225:3: error: expected expressionĪARCH64_INIT_MEMTAG_BUILTINS_DECL (IRG, irg, irg, fntype) But now I’m stuck with `make` failing at `config/aarch64/aarch64-builtins.c` as follows (edited for clarity): Using information from the `` file from GCC’s source tree, I managed to patch a few things to the best of my knowledge. `make` builds GCC 10.1.0 and exits successfully. For the exact command lines passed to clang, configure and make, please see the attached shell script.Ĭollection of source files for reproducing the bug, preferably a minimal set: Not applicable because I’m trying to build GCC. Based on Apple Silicon, which currently is an A12z SoC based on the armv8.3 architecture.Įxact command line passed to the gcc program triggering the bug: I have GNU make 3.81 installed, which was built from source using `brew install make`. I’m running macOS 11.0 beta 1 on Apple Silicon. I’m trying to build (bootstrap) gcc 10.1.0 from the source tarball. But it shows that it’s not entirely unrealistic to build GCC 10 for aarch64/Darwin so I gave it a try. I have learned that it’s completely unfeasible to forward-port those so I haven’t tried that yet.

IIRC, there have been successful third-party efforts to build older GCC versions (such as GCC 4) for aarch64/Darwin already, targeting iOS. I assume you have heard of Apple’s plans to switch to aarch64 hardware for Macs.Īs a maintainer for the Homebrew package manager for macOS, I’m trying to figure out how to build the most important FOSS projects on the new Apple Silicon hardware. Thanks in advance for hearing me out even though I have near-zero experience in C/C++ programming. Minimal shell script to reproduce the failure
