Hello, you're receiving this canned bug because the package in summary uses the flag -Werror during build, which transforms warnings in errors, and is prone to break software when new GCC releases are added to Gentoo. Please make sure your package does not use -Werror during build, so that it can be more future-proof for the new GCC releases. Thanks, Diego
The flag can be removed by putting the following line into src_unpack(): sed -i 's/-Werror//' {tpmd_dev,tpm_dev,tddl,tpmd}/Makefile I'll try to contact upstream and see if I can separate devel and end-user build targets.
No longer relevant with 0.5.1, as it was fixed upstream.
