Greater the number of jobs more scattered the log. Your real error is probably much earlier in the log.

Post by **Ionen** » Fri Jan 29, 2021 6:59 pm

There's plenty of people using clang+lto+pgo (so am I with 85.0), so it's supposed to work. It's also the configuration upstream uses for firefox-bin so it tend to be well supported.

But as above post points, the error happened earlier on so can't spot it in that small paste.

Also, emerge --info would help. Are you using tmpfs for building this? (don't if so)

I have /usr/lib/clang/11.0.0/lib/linux/libclang_rt.profile-x86_64.a from sys-libs/compiler-rt-sanitizers-11.0.0, but not 11.0.1

adding ~amd64 keyword (as I have for clang) to sys-libs/compiler-rt-sanitizers and trying again

BTW. tmpfs is disabled for firefox

ccache - it can throw in the monkey wrench.

Since I was stuck on 84.0.1-r1 -lto, I added +lto to my package.use giving it +clang +lto +pgo and -dbus and let it rip. 85.0. Compiled fine, taking a about 75 minutes. Seems to work as expected. Build log about 30 M. I feel overly bleeding edge.

Changing the keywords of sys-libs/compiler-rt-sanitizers to match clang helped

Speed is also improved

Remember that +pgo can nearly double the build-time.

I'm happy following the ESR line that is kept stabilized in Gentoo :)
