Thank you for the report. Please *attach* the logfiles,
https://wiki.gentoo.org/wiki/Bugzilla/Bug_report_guide#Report_a_build-time_bug_.28emerge_failed.29
and reopen this ticket (Status:unconfirmed).

[Comment 2 David Heidelberg (okias) 2017-10-19 14:20:05 UTC]

I'm not able to upload logs (timeout), but I noticed this error shows up when compiling even other software, so it's not gnome related.

Reopened since this causing multiple ebuilds to fail at compilation time.

Can you give us a list of other packages that fail for you with the same error? 
Just the package names for now.

Oh and your emerge --info would be useful too.

[Comment 6 Andreas K. Hüttel 2017-10-29 18:15:31 UTC]

I can not reproduce this problem. gnome-extra/evolution-data-server emerges fine here in my ~amd64 chroot.

(To be precise, gnome-extra/evolution-data-server-3.24.6 ... no idea where you get your version from...)

[Comment 7 Sergei Trofimovich (RETIRED) 2017-10-29 20:05:54 UTC]

The problem here is in 'libbfd-2.29.1.so' (or the linker tryng to read it):
> lookup error: /usr/lib64/libbfd-2.29.1.so: undefined symbol: _hex_value

It should get the read-only symbol:

$ gcc-nm -D /usr/lib64/libbfd-2.29.1.so | fgrep hex_val
000000000063e640 R _hex_value

Do you have it? 'ld -v' should also be useful ('emerge --info' will contain it)

[Comment 8 David Heidelberg (okias) 2017-10-31 11:26:32 UTC]

# gcc-nm -D /usr/lib64/libbfd-2.29.1.so | fgrep hex_val
                 U _hex_value

# ld -v
GNU ld (Gentoo 2.29.1 p2) 2.29.1

[Comment 9 David Heidelberg (okias) 2017-10-31 11:40:35 UTC]

I figured it out, it's LTO issue. Now question is if it's in binutils-libs or GCC 7.2.0.

# gcc-nm -D /usr/lib64/libbfd-2.29.1.so | fgrep hex_val
000000000010bea0 R _hex_value

# ld -v
GNU ld (Gentoo 2.29.1 p2) 2.29.1

[Comment 10 David Heidelberg (okias) 2017-10-31 11:49:59 UTC]

when binutils-libs are compiled with 5.4.0 + LTO, it fails same way as with 7.2.0 LTO. It _seems_ to be binutils-libs bug.

Can you attach your 'emerge --info' on a failing system?
Is setting CFLAGS/CXXFLAGS/LDFLAGS+=-flto enough to reproduce the failure?

[Comment 12 Sergei Trofimovich (RETIRED) 2018-10-27 21:29:35 UTC]

Given that error comes from ld itself I'm assuming it's a dupe of bug #666100.
