I'm having trouble to compile sys-devel/mold on a musl chroot, and seems this will be a problem for all packages that build and link against libtbb.so libs, if this is attempted with a musl based env: ldd /usr/lib/libtbb.so.12.5 ldd (0x7f91aa6000) libstdc++.so.6 => /usr/lib/gcc/aarch64-gentoo-linux-musl/10.3.0/libstdc++.so.6 (0x7f9187b000) libgcc_s.so.1 => /usr/lib/gcc/aarch64-gentoo-linux-musl/10.3.0/libgcc_s.so.1 (0x7f91857000) libc.so => ldd (0x7f91aa6000) Error relocating /usr/lib/libtbb.so.12.5: swapcontext: symbol not found Error relocating /usr/lib/libtbb.so.12.5: getcontext: symbol not found Error relocating /usr/lib/libtbb.so.12.5: makecontext: symbol not found the symbols are wanted in the headers: https://github.com/oneapi-src/oneTBB/blob/master/src/tbb/co_context.h#L324 I've often seen that devs stub this stuff out of the way with glibc specific ifdefs, is that an option here?

We need to force linking against libucontext.
never heard about that lib, but guess what happens when you compile it: ldd /usr/lib/libucontext_posix.so.1 ldd (0x7fbb773000) libc.so => ldd (0x7fbb773000) Error relocating /usr/lib/libucontext_posix.so.1: libucontext_getcontext: symbol not found Error relocating /usr/lib/libucontext_posix.so.1: libucontext_swapcontext: symbol not found Error relocating /usr/lib/libucontext_posix.so.1: libucontext_setcontext: symbol not found
for some more clues on the problem, read the github issue please.
Thanks for reporting that.
I'll call this a dupe of the other one as the other one got tagged with the fix commit. *** This bug has been marked as a duplicate of bug 832700 ***
