Hi, This is new in grep 2.23 (see NEWS). Unfortunately, it breaks our package submission process for packagers with UTF-8 chars in their PACKAGER var. The issue happen in makechrootpkg when it uses grep to load variables from makepkg.conf. Example 1: $ extra-x86_64-build ... ==> Building in chroot for [extra] (x86_64)... /usr/bin/makechrootpkg: line 319: Binary: command not found ==> Creating clean working copy [seblu]...done Example 2: $ LANG=C grep '^PACKAGER=' /home/seblu/.makepkg.conf Binary file /home/seblu/.makepkg.conf matches Example 3: $ LANG=en_US.UTF8 grep '^PACKAGER=' /home/seblu/.makepkg.conf PACKAGER='Sébastien Luttringer <seblu@seblu.net>' I see these way of fixing this: - add --text to grep calls in devtools - replace LANG=C by LANG=en_US.UTF8 in lib/common.sh What's do you thinK?
