Description Amit Prakash Ambasta 2016-10-28 08:49:39 UTC
Hi,

While building boost with clang and LTO, the following error occurs:

bin.v2/libs/atomic/build/gcc-4.2/gentoorelease/boost.locale.icu-off/pch-off/threading-multi/lockpool.o: file not recognized: File format not recognized

The clink command (and verbose) to the same are:

This occurs since the gold plugin is not being passed to the linker. However, both binutils-config --linker ld.gold and LD="ld.gold" in make.conf are set

Manually adding:
-plugin /usr/x86_64-pc-linux-gnu/binutils-bin/lib/bfd-plugins/LLVMgold.so

to the ld command fixes this however.

Apologies, the verbose output of the link command is as below:

boost build log
Comment 5 Steve Arnold gentoo-dev 2016-11-05 18:47:23 UTC
Hmm, boost-1.61 builds fine with default lto/vectorize/graphite flags, however boost-build needed a little env help (adding  -std=gnu89 as workaround to avoid nasty QA warnings about implicit declarations).

Now, boost-build-1.62 is the same as 1.61 but boost-1.62 fails with -flto or just the gold linker.  It builds as above (but without -flto or gold) so the rest of the "normal" optimization flags seem okay.

This is all with ~amd64 toolchain, not tried it with clang/llvm.  AFAICT the linker plugin stuff is handled correctly with the standard toolchain.

Without lto and just gold I get this:

boost-1.61 is no longer part of the portage tree and the bug does not affect 1.63+
