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

Hi Pete, thanks for the detailed report! We've made some updates on the Musl side and if you rebuild it from the top of the "morello/master" branch, you should get two improvements:

1. The need for extra env vars for installing kernels from source has been removed: we now download kernel headers for Morello and just unpack them.
2. With a fix to Musl dynamic linker, exceptions in C++ should now work in static binaries.

Hope this helps!

Thanks Yury, I look forward to giving it another try sometime next week!

Hi Yury, just reporting back, I updated from master and re-tested and indeed the two changes you described worked well - many thanks!

I appreciate there is still a little bit more work to do (e.g all those build warnings are still there), but do you have an updated estimate for when there will be an official release of this MUSL libc++ support?

Best Regards
Pete
