I think that this is bug in glibc version of sys/ucontext.h header on some architectures (rather only PPC{32,64} relevant for Gentoo):
https://sourceware.org/bugzilla/show_bug.cgi?id=28938
Problem should not occur in musl systems.
In glibc system, you can add this line to your /usr/include/sys/ucontext.h (e.g. somewhere close to definition of gregset_t):
typedef unsigned long greg_t;
And try building sys-libs/libucontext again.
Is sys-libs/libucontext ONLY intended to be used on musl? Based on the description, it seems like it's not totally useless on glibc systems (maybe you want an alternative ucontext implementation for a specific project?) but I want to make sure that upstream even supports that as a use case before opening a ticket with them. The bug has been closed via the following commit(s): https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=07d32a980a910272e3d2e92d70c8b8f38c9406da commit 07d32a980a910272e3d2e92d70c8b8f38c9406da Author: matoro <matoro@users.noreply.github.com> AuthorDate: 2022-09-19 01:31:15 +0000 Commit: Sam James <sam@gentoo.org> CommitDate: 2022-09-25 01:27:23 +0000 profiles: mask sys-libs/libucontext on non-musl Closes: https://bugs.gentoo.org/834450 Closes: https://github.com/gentoo/gentoo/pull/27342 Signed-off-by: Sam James <sam@gentoo.org> profiles/base/package.mask | 1 + profiles/features/musl/package.mask | 1 + 2 files changed, 2 insertions(+) |
