Hi,

Is there a way to install riscv-tools on m1 Macs? when I run brew install riscv-tools I got error:

No. riscv-tools needs a gcc cross compiler, and a cross compiler still needs info about the build system (i.e. the M1 Mac) so it can figure out how to translate stuff from the build system to the target system. FSF GCC currently has no build system support for M1 Macs. This needs to be added upstream, and then pulled down into riscv-gnu-toolchain. That could be a while. See for instance https://github.com/riscv/riscv-gnu-toolchain/issues/800
