And unfortunately the build failure still happens with that version. In the mean time, there is a separate bug report for this issue for SeaBIOS that it fails to build from source in Debian [4]. I successfully build SeaBIOS with GCC 6-20161020, so it’s a Debian packaging issue. Probably due to the change below. > * Configure with --enable-default-pie and pass -z now when pie is enabled; > on amd64 arm64 armel armhf i386 mips mipsel mips64el ppc64el s390x. > Closes: #835148 [6]. I added `no-pic` to the COMMON_CFLAGS, and that fixed the build issue for me. I don’t understand, what that has to do with PIE though.
