When using BR2_ROOTFS_DEVICE_TABLE to change ownership of /etc, like so: /etc r -1 root wheel - - - - - makedevs fails due to trying to chown() a dangling symlink: makedevs: chown failed for /src/myLinux/output/build/buildroot-fs/ext2/target/etc/mtab: No such file or directory makedevs: line 25: recursive failed for /src/myLinux/output/build/buildroot-fs/ext2/target/etc: No such file or directory make[2]: *** [fs/ext2/ext2.mk:63: /src/myLinux/output/images/rootfs.ext2] Error 1 make[1]: *** [Makefile:84: _all] Error 2 make[1]: Leaving directory '/src/myLinux/buildroot' This patch changes chown() to lchown() in two cases in makedevs.c when the argument can be a symlink, dangling or not. In case the recursive operation includes a chmod() as well, explicitly exclude symlinks that are dangling, because chmod() always operates on the link target.

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.
