Gentoo build: undefined reference to symbol 'del_curterm'`

[binary132]

Gentoo users who have dev-util/nvidia-cuda-toolkit are affected by Gentoo bug 457530. This is caused by libtinfo not being linked normally to libncurses for these users.

libLLVMSupport.a(Process.o): undefined reference to symbol 'del_curterm'

In the meantime, this can be hotfixed (confirmed works) by adding /lib/libtinfo.so.5 to the GROUP statements in the /usr/lib/libncurses[w].so ld scripts.

A clumsy workaround for users without root privilege is to add -ltinfo to the Makefile llvm.libs (confirmed works). Gentoo root users should be expected to hotfix the bug, as the fix is extremely simple. However, not all users may have su privilege to make this change. These users should be expected to contact their system administrator to make the fix.

Thanks for the report and the PR. Shall we leave this open until the Gentoo bug is resolved?

It's not a ponyc problem, and now the README refers Gentoo users to the workaround. ISTM Gentoo users can be expected to read the build instructions, at least until they have an overlay.... 💡
