I am trying to build QEMU v8 in Ubuntu VM on M1 MAX. make toolchains seems to have built okay, but make run ended up with an error:

# Ensure the toolchain, components, and targets we've specified in
# rust-toolchain.toml are ready to go. Since that file sets rustup's
# default toolchain for the entire directory, all we need to do is run
# any rustup-wrapped command to trigger installation. We've arbitrarily
# chosen "cargo --version" since it has no other effect.

I'm on branch 4.2.0 and using the upstream's qemu_v8.xml file.

Hi @ikitayama,

This is a known issue, see #747 (comment). TL;DR: use make -j$(nproc) RUST_ENABLE=n.

If you can find a way to make it work you're welcome to submit pull requests. In the mean time I think we should force RUST_ENABLE=n on non-x64_64 hosts. I'll make a PR for that.

Thanks!

Indeed, GCC 12 is incompatible with C++ TAs. One more thing to disable on M1. So make -j$(nproc) RUST_ENABLE=n WITH_CXX_TESTS=n.

@ikitayama please see #764

Thanks! That worked.

Requiring that buildroot's GCC be 11 leads to a make toolchains failure.

It looks like Buildroot has lost support for GCC 11.x :-/ can you please try this patch:

It will likely not work due to BR2_KERNEL_HEADERS_6_1=y being incorrect, but I do not know which version is expected for GCC 14.x, so please report any error message and we will take it from there. Thanks!

It seems to be working? I am seeing two xterms saying "Secure World" and "Normal World" on my M1 Max. Builds were done in Ubuntu VM.
