riscv-gnu-toolchain build from source fails

[cookiestuf]

Hi,

I'm trying to build the riscv-gnu-toolchain from source but I'm running into a missing file error. Any advice on how to proceed? Running OS X High Sierra 10.13

I appreciate this report!

I am able to build riscv-gnu-toolchain both by rebuilding within Homebrew and by building it directly from its repo. Being unable to reproduce this issue, it is challenging for me to debug.

I imagine there might be an issue during the build process if homebrew is somehow not recursively cloning the submodules.

Could you try building it directly from the repo?

Please let me know if you find anything new.
