2 years ago Thank you for bringing up this issue.
Unfortunately I don't have an ARM64 platform to test on. But I think you should raise this issue with the respective project that uses pthreads. The logs you provided unfortunately don't say what tool it is trying to build. It seems like an issue within Cmake?
That said, if it is a problem within a tool that summon-arm-toolchain is building the right place to report and resolve the bug is in the up stream project itself. Unless we can change the script in some subtle way to avoid the issue.
Also as this issue is already few months old. Did you try build the tools since then? I know that oss-cad-suite does build an ARM64 artifact so it should be possible to build.
Not sure how to proceed
