Created attachment 687918 [details] build log This is my first ebuild attempted with the lto useflag so I imagine this applies to 1.46.0 as well. Build is successful with USE="-lto". I see that sys-devel/gcc has an "zstd" useflag: I surmise that were this enabled, the e2fsprogs build would also succeed? (This is on an old machine and I do not rebuild gcc on a whim, especially with lto) Error message and preamble: /usr/bin/gcc-ar rc libe2p.a feature.o fgetflags.o fsetflags.o fgetversion.o

My guess is that you used to have a gcc with USE=zstd enabled before (it was an implicit flag) and ccache cached object files with zstd compression. Now your gcc only supports zlib compressed lto files. ccache is very tricky to get right when underlying compiler changes. I generally suggest using setup similar to https://wiki.gentoo.org /wiki/Ccache#Configuration # Preserve cache across GCC rebuilds and # introspect GCC changes through GCC wrapper. compiler_check = %compiler% -v Where very detailed compiler version seeds ccache key instead of a wrapper you might use.
OK, I see now. One of my distcc helpers (non-Gentoo) is built with zstd, so when I excluded that host the LTO build of e2fsprogs was successful. That helper is prebuilt, so I guess I'll go ahead and enable zstd on my Gentoo gcc's. Thanks for the tip.
