By default, cut prints the entire line if the specified delimiter is not present at all: $ printf "foo bar" | cut -d' ' -f2 bar $ printf "foobar" | cut -d' ' -f2 foobar In setlocalversion, cut is presented with the output of 'hg id' which has the format: "<revision> <tags-if-any>" If the current revision is not tagged, the output of 'hg id' does not contain the delimiter (space), cut prints the entire string, and setlocalversion thinks the version is the tag. As setlocalversion does not print anything for tagged versions, there is no output overall, and no correct indication of the mercurial revision. Fix by passing the extra cut option '--only-delimited', which suppresses output if no delimiter is found. This problem likely went unnoticed for so long, because the tag 'tip' (i.e. most recent revision of the branch) is treated specially: in this case the mercurial revision _is_ printed, i.e. the situation is treated as 'untagged'. The problem is only seen when you are _not_ at the most recent revision in your branch.

Buildroot is a simple, efficient and easy-to-use tool to generate embedded Linux systems through cross-compilation. The documentation can be found in docs/manual. You can generate a text document with 'make manual-text' and read output/docs/manual/manual.text. Online documentation can be found at http://buildroot.org/docs.html To build and use the buildroot stuff, do the following: 1) run 'make menuconfig' 2) select the target architecture and the packages you wish to compile 3) run 'make' 4) wait while it compiles 5) find the kernel, bootloader, root filesystem, etc. in output/images You do not need to be root to build or run buildroot. Have fun! Buildroot comes with a basic configuration for a number of boards. Run 'make list-defconfigs' to view the list of provided configurations. Please feed suggestions, bug reports, insults, and bribes back to the buildroot mailing list: buildroot@buildroot.org You can also find us on #buildroot on Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
