We sanity-check the host executables that they have a correct RPATH pointing to the host libraries. This is currently done by looking for all files in $(HOST_DIR) that match the 'ELF executable' pattern (a bit more complex, but that's idea). However, when an executable is built with -fPIE of -fpie, it no longer appears to be an 'ELF executable', but it rather looks like an 'ELF sheard object' (like if it were an library. So, we miss those files. It turns out that the problem is a real one, because quite a few mainline distros, expecially those based on Debian for example, have already switched to generating PIE code by default, and thus we miss on a whole class of systems.. We fix that by simply looking if we can find an ELF interpreter in each file. If we there is one, this is an ELF executable; if not, it may be anything else: we don't care (not even about ELF libraries). 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 Freenode IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
