PlatformIO Build error on macOS Intel, Bad CPU type in executable

[donly]

It works very well on Apple Silicon.

And I found the issue maybe caused by the toolchain-riscv.

otool -hv ~/.platformio/packages/toolchain-riscv/bin/riscv-wch-elf-g++
/Users/donly/.platformio/packages/toolchain-riscv/bin/riscv-wch-elf-g++:

I also found that it can be built under a specific version of toolchain-riscv using @Zeron's method #89

True. The repo for the Mac toolchain, https://github.com/Community-PIO-CH32V/toolchain-riscv-mac/ should only have Intel x86 binaries and a new repo should be made and used for Mac ARM64. This will be corrected shortly.

Actually, WCH does not provide the current GCC12 toolchain for MacOS Intel. Only ARM64. It says "MacOS_x64" but it's actually ARM64 files inside the Toolchain archive at http://www.mounriver.com/download.

I've sent an EMail to MounRiver support. In the meantime, the latest commit 74097c0 downgrades MacOS Intel users to GCC8 again.. So they can at least build "something".

Hello Maximilian,
Sorry for the inconvenience. Currently, we only support ARM architecture, and there are no plans to support Intel architecture in the near future.

Well, they said "no". Too bad for Intel Mac users.

I'm now trying to obtain the GCC12 source code from them. They must do this due to the GPLv3 license of GCC. But, companies rarely comply..

Thanks for the update, Maxgerhardt.

They denied my request for the source code "at the moment" because "they are in a phase of rapid iteration". I gave them 4 weeks of time to comply with the GPL licence.
