build log

I succeeded in building app-office/libreoffice-7.0.4.2[-clang,+vulkan], but got this warning "Building skia with gcc may lead to performance issues. Disable vulkan or enable clang."

So I tried to build app-office/libreoffice-7.0.4.2[+clang,+vulkan]. However, it fails at econf.

Comment 2 Ionen Wolkens gentoo-dev 2021-02-03 09:48:54 UTC 
This is because bashrc-mv is putting LDFLAGS inside your CXXFLAGS.

fails: CXXFLAGS='-O2 -pipe -pipe -march=native -Wl,-O1 -Wl,--as-needed'
works: CXXFLAGS='-O2 -pipe -march=native'

Not sure what else to do than closing this as invalid.
