https://blogs.gentoo.org/ago/2020/07/04/gentoo-tinderbox/ Issue: media-sound/guitarix-0.44.1 fails to compile (lto). Discovered on: amd64 (internal ref: lto_tinderbox) NOTE: This machine uses lto with CFLAGS=-flto -Werror=odr -Werror=lto-type-mismatch -Werror=strict-aliasing
Created attachment 794153 [details] build.log build log and emerge --info
Error(s) that match a know pattern in addition to what has been reported in the summary: Checking for 'jackd1' : not found collect2: error: ld returned 1 exit status
Getting the same compile error, guitarix seems to build with flto on by default (-flto=auto) with fuse-linker-plugin /usr/lib/gcc/x86_64-pc-linux-gnu/13.2.1/../../../../x86_64-pc-linux-gnu/bin/ld: src/gx_head/gui/gx_main.cpp.1.o: plugin needed to handle lto object /usr/lib/gcc/x86_64-pc-linux-gnu/13.2.1/../../../../x86_64-pc-linux-gnu/bin/ld:../src/gx_head/guitarix.lds:1: undefined section `.rt.text' referenced in expression collect2: error: ld returned 1 exit status

This allows waf to do some magic and append -ffat-lto-objects to CXXFLAGS. Also unexport CXXFLAGS and LDFLAGS before waf configure to prevent duplicating flags.

Still getting an LTO-related error for this one. Should I open a new ticket? Output shows a number of these kinds of messages: /usr/lib/gcc/x86_64-pc-linux-gnu/13/../../../../x86_64-pc-linux-gnu/bin/ld: src/gx_head/engine/ladspaplugin.cpp.1.o: plugin needed to handle lto object And: /usr/lib/gcc/x86_64-pc-linux-gnu/13/../../../../x86_64-pc-linux-gnu/bin/ld:../src/gx_head/guitarix.lds:1: undefined section `.rt.text' referenced in expression collect2: error: ld returned 1 exit status
(In reply to Andrew Udvare from comment #5) > Still getting an LTO-related error for this one. Should I open a new ticket? Yes, please. This is probably a different issue. I tested with the same *FLAGS as @ago end everything worked fine on my system.
