64 bit arm not supported

[MatthiasLohr]

Environment information

• py-solc-x Version: 0.10.0
• solc Version: 0.6.1
• Python Version: 3.8.2
• OS: Ubuntu (Raspberry Pi, 64 Bit)

What was wrong?

According to release v0.10.0, arm architectures should be supported. However, it seems that this support is only limited to 32 bit arm architectures.

Code is checking for platform.machine() ^= "arm", but on my Raspberry Pi 3 B+ with Ubuntu/64 bit support, platform.machine() returns aarch64.

Good catch.. the fix should be as easy as adding a check for aarch in install.py i think?

I have no way to test this. Would you be willing to fork and make the edit and see if it works as expected? 🙏

[MatthiasLohr]

Will do!

Also worth noting, there is an effort right now to increase the availability of solc binaries: ethereum/solidity#9258

This repo is due for a refactor and a new major release, I've been holding off in hopes that osx and arm binaries are made available so these sort of issues become less-so....

Ok, it's compiling.. since about 30 minutes (and it shows 21%). Compiling on an ARM seems not to be the best idea :D

First thing learned: Maybe binary filenames should be postfixed with architecture. If file solc-v0.6.5 exists, it will just try to execute it, no matter on which architecture we are now and for which architecture is was built.

[MatthiasLohr]

Next thing learned: Don't try it with only 1GB RAM.

:) What about a release now?

thanks for all your help with this release!

[MatthiasLohr]

Sure! And thanks for reacting so quickly! Update is already installed, will test now.

Downloaded the tar.gz file and ran the "pip install py-solc-x" command on Raspberry Pi 4 terminal. However, the installation is still not successful. May someone please advise as to what steps should be taken? Thank you!
