The autofs configure script does a number of weird things. First, instead of using the default search path for AC_CHECK_PROGS(), it overrides it its own search path, ignoring the PATH environment variable. Due to this, autofs fails to find flex even though flex is available in the PATH. Fortunately, the authors provided a --with-path configure option which allows to override this search path. In addition, the configure script is checking on the build machine that a number of programs are available, while those programs are in fact only needed on the target. The one causing build issues is modprobe, because it may not necessarily be installed on build machines, so we explicitly tell autofs that modprobe is located in /sbin/modprobe. It might be necessary to provide additional values for other programs, as we discover other problems.

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.
