C++ Standard library support in Morello linux pure-cap

Hi there,

I'm not sure this will help your specific use-case, but in case (and anyone else reading):

There is a libstdc++ in the GNU Morello toolchain, which can be found here https://developer.arm.com/downloads/-/arm-gnu-toolchain-for-morello-downloads.
(Heads-up the GNU toolchain is alpha quality).

Cheers,

Matthew

Hi Pete,

Thanks for the question! We're working on adding C++ binaries into the LLVM toolchain for Linux and it should become available via the artefact on GitLab that you mentioned in a few weeks time. At first, it is going to be experimental, so any feedback would be greatly appreciated. I'll add a comment here once you can download it from GitLab.

Thanks,
Yury

Hello Pete,

A quick update. We have recently updated one of the scripts that are used to build the toolchain: tools/build-morello.sh. New version have three experimental steps: libunwind, libcxxabi, and libcxx. They allow to build C++ libraries from LLVM for purecap target and link them to purecap Musl. I must warn that they are very experimental at this point only build static versions of these three libraries, but you are welcome to try and see if it works for you. We hope to improve this at some point.

Thanks,
Yury

Another quick update: this document should hopefully explain how to use build-morello.sh script: build-morello-clang.rst.

Thanks,
Yury
