Package: src:grub2 Version: 2.02~beta2 Severity: minor
Dear Maintainer, Hello, Using the rebuild infrastructure, your package fails to build with clang instead of gcc. Error message is: error: unknown warning option '-Wno-unused-but-set-variable'; did you mean '-Wno-unused-const-variable'? [-Werror,-Wunknown-warning-option] Full build log is available here: http://clang.debian.net/logs/2015-03-25/grub2_2.02~beta2-22_unstable_clang.log Thanks, Joseph -- System Information: Debian Release: stretch/sid APT prefers unstable APT policy: (500, 'unstable') Architecture: amd64 (x86_64) Kernel: Linux 4.0.4-2-ARCH (SMP w/8 CPU cores; PREEMPT) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) (ignored: LC_ALL set to en_US.UTF-8) Shell: /bin/sh linked to /bin/dash
