Commit1187c34d88(support/scripts: move merged-usr errors message into check-merged-usr.sh) introduced the use of getopt to parse its options; doing so allowed to use long option (with two leading dashes), which is more descriptive than the usual one-character options. However, getopt is part of util-linux; it is not a shell built-in. util-linux is not a prerequisite of Buildroot, so we may end up running on a system where it is missing. We could add host-util-linux as a dependency when the system does not provide getopt, but that's not very nice; even though host-skeleton does not need to check for merged-bin for now, it does not need getopt, and thus we could add host-util-linux (which depends on host-skeleton) as a dependency of skeleton-custom. But that will not be tenable over the long run, especially if/when we do a merged-bin in host dir. Requiring that util-linux be installed system-wide is not nice either; it's an additional requirement on the host. We can do like we do in the oter scripts, though: use the shell built-in getopts. Its usage is slightly different, and does not support long options. As it's just for use in an internal script, we can live with the less descriptive options, though. Switch to using getopts, it removes the need for a new host dependency. Fixes:1187c34d88Reported-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com> Signed-off-by: Yann E.

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 OFTC IRC.
