After run "lto-rebuild -r" nothing happens

[Cerberios]

Hello there!
Please can You help identify issue - when I run

lto-rebuild -r

nothing happens al all - output the same for any params (a,h,l,r)

`Searching in
/usr/lib
/usr/lib64
/usr/lib32
for static archives that were built using a different GCC...

No problems found!`

Thanks!

@Cerberios what is your gcc?
and what did you upgrade from?

I upgraded from gcc-9.3.0

It's possible, but unlikely, that there are simply no static archives built with gcc 9.3.0 on your system. Can you find an archive, for example libz.a, that was built with gcc 9.3.0 with LTO?

[Cerberios]

Good day, Shane! No, there are nothing was built with gcc 9.3.0 with LTO. I made fresh installation, added LTO repo and then upgraded GCC 9.3.0 --> 10.2.0 with LTO-features enabled. For now I'd like to rebuild whole system.

emerge -e @world would do just that.
