I have seen some of you who solve this problem with removing directory riscv-gnu-toolchain--git in Cache #73 But it does not work well. I still get a problem like this. I would love to see a solution from you guys

Also having an issue with the 'zifencei' required for a M1 Pro MacBook.

[rain7996]

I meet the same problem. Have you solved it?

[MusLead]

So, I hope they find solution for this. The biggest problem is because this RISC-V is not designed for ARM64 architecture. Therfore we need to do something.

The steps is also from ChatGPT generated.

I assume you have installed arch x86-64 and Rosetta x64 on you mac M1. The follow this instruction bellow:

This is for those who are trying to install RISC-V on Mac with ARM-Based Processor. You should be aware that RISC-V cannot be install just with brew install riscv-tools it will return some error, becuase this RISC-V is designed for x86_64 architecture. therefore, there must be some some additional command.

'''
arch --x86_64 /usr/local/bin/brew tap riscv/riscv
arch --x86_64 /usr/local/bin/brew install riscv-gnu-toolchain
'''

This command actually works for me to install and to compile later on using make qemu. I hope this solution can also help you guys, for those who are using Mac with processor M1/M2. If there are some suggestion for me, please let me know. Probably there is another alternative solution that better than mine.

I created the pull request above, because it fixes the issue (both the compilation error, and the resulting binary - pk - works fine) under ARM64 (Apple Silicon) by modifying the compiler options accordingly ("zifencei" explicitly enabled)

how can I use your version? Does the two command 'brew tape gmerlino/homebrew-riscv' and 'brew install riskv-tools' work fine?

[sbeamer]

Can someone confirm this is still an issue? riscv-pk reverted the commit that caused this issue: riscv-software-src/riscv-pk@acbe166

[Justus2308]

It still doesn't work for me, I get the same error on a M1 MacBook Pro

gmerlino's solution works fine with me. I use the commands 'brew tape gmerlino/homebrew-riscv' and 'brew install riskv-tools' instead of the official. I thought this issue could be closed.

Same for me. I'm using a MacBook Pro 16 (M1 Pro) with macOS Ventura 13.4.

After merging #101 should ok (for now)
