--- Comment #17 from Evgeny Karpov <Evgeny.Karpov at microsoft dot com> --- > What is the current status of GCC for aarch64-w64-mingw32 ? > When can I expect a snapshot version of GCC 15 to build for this platform? The current upstreamed aarch64-w64-mingw32 uses 605k tests and shows a success pass rate of 89%, including C/C++. It will be released with GCC 15. Here is detailed information about the recent upstreamed patch series in November 2024: https://gcc.gnu.org/pipermail/gcc-patches/2024-September/662017.html SEH and full Boost library support should be upstreamed in Q2 2025. However, the current implementation can be found at https://github.com/Windows-on-ARM-Experiments/mingw-woarm64-build, including the initial implementation for aarch64-pc-cygwin. Please report any issues to https://github.com/Windows-on-ARM-Experiments/mingw-woarm64-build/issues.
