There is a new feature in latest rsync to support SIMD functions. The latest ebuild toggles this on if the architecture is detected as amd64. However, I believe that "ifunc" is not supported on libc other than glibc. So no support on uclibc-ng, (and that I know of) uclibc, musl. This triggers a build error on uclibc-ng (and probably musl) architectures with the following: ... ./simd-checksum-x86_64.cpp: In function 'uint32_t get_checksum1_cpp(char*, int32_t)': ./simd-checksum-x86_64.cpp:88:52: error: multiversioning needs ifunc which is not supported on this target 88 | __attribute__ ((target("default"))) MVSTATIC int32 get_checksum1_avx2_64(schar* buf, int32 len, int32 i, uint32* ps1, uint32* ps2) { return i; } | ^~~~~~~~~~~~~~~~~~~~~ ./simd-checksum-x86_64.cpp:474:1: error: use of multiversioned function without a default 474 | } | ^ ./simd-checksum-x86_64.cpp:89:52: error: multiversioning needs ifunc which is not supported on this target 89 | __attribute__ ((target("default"))) MVSTATIC int32 get_checksum1_ssse3_32(schar* buf, int32 len, int32 i, uint32* ps1, uint32* ps2) { return i; } | ^~~~~~~~~~~~~~~~~~~~~~ ./simd-checksum-x86_64.cpp:474:1: error: use of multiversioned function without a default 474 | } | ^ make: *** [Makefile:135: simd-checksum-x86_64.o] Error 1 I think the correct fix in this situation is to have the build tighten up it's check for "use_enable simd" and ensure it's only enabled on glibc (or equivalently exclude uclibc-ng and probably musl) Apologies for the lack of patch, but i think this a fairly trivial one liner. Thanks Reproducible: Always
Please emerge --sync and check this change has been applied: https://gitweb.gentoo.org/repo/gentoo.git/commit/?id=3dd34a97435475f490756095307aeade0acf86e2 This should resolve your problem.
Aha, yep, fair enough. That's done it. Apologies, I was using the stable version (3.2.0) and although I unmasked that one I also modified it, so failed to notice the change. Thanks for the quick fix, recommend pushing to stable as it's possible Thanks!
