Hi Folks I am trying to build up my toolchain for 5.x. Unfortunately the build process fails with
..... buildtool Version 0.7 starting Fri Oct 11 14:17:22 2013 checking build environment trace support not enabled in configfile make: Entering directory `/data/leaf/devel/leaf.new/bering-uclibc/source/i486-unknown-linux-uclibc/linux' /data/leaf/devel/leaf.new/bering-uclibc/tools/setup-builddir -v linux-3.4.tar.xz /data/leaf/devel/leaf.new/bering-uclibc/tools/setup-builddir: line 134: ${filetype,,}: bad substitution Error: unable to read the top-level directory of 'linux-3.4.tar.xz' make: *** [.source] Error 1 make: Leaving directory `/data/leaf/devel/leaf.new/bering-uclibc/source/i486-unknown-linux-uclibc/linux' looking at the corresponding shell code I find case ${filetype,,} in # convert to lowercase My shell appears not to recognize the {$xxx,,} notation (neither do I) Removing the offending construct leads to Unrecognized file format of 'linux-3.4.tar.xz' Well that is pretty obvious, as the file utility just returns linux-3.4.tar.xz: data So the finding of the file utility is not really satisfying. I am not a friend of determining a file type by suffix, I don't know how the file utility does it. Anyway, kernel.org has in their great wisdom decided to use a new format, shame on them. It breaks compatibility in many places. cheers Erich
