As shown recently by the firejail example, it is easy to miss that a package builds and installs binaries without actually cross-compiling them: they are built for the host architecture instead of the target architecture. This commit adds a small helper script, check-bin-arch, called as a GLOBAL_INSTRUMENTATION_HOOKS at the end of the target installation of each package, to verify that the files installed by this package have been built for the correct architecture. Being called as a GLOBAL_INSTRUMENTATION_HOOKS allows the build to error out right after the installation of the faulty package, and therefore get autobuilder error detection properly assigned to this specific package. Example output with the firejail package enabled, when building for an ARM target: ERROR: architecture for ./usr/lib/firejail/libconnect.so is Advanced Micro Devices X86-64, should be ARM ERROR: architecture for ./usr/bin/firejail is Advanced Micro Devices X86-64, should be ARM ERROR: architecture for ./usr/lib/firejail/libtrace.so is Advanced Micro Devices X86-64, should be ARM ERROR: architecture for ./usr/lib/firejail/libtracelog.so is Advanced Micro Devices X86-64, should be ARM ERROR: architecture for ./usr/lib/firejail/ftee is Advanced Micro Devices X86-64, should be ARM ERROR: architecture for ./usr/lib/firejail/faudit is Advanced Micro Devices X86-64, should be ARM ERROR: architecture for ./usr/bin/firemon is Advanced Micro Devices X86-64, should be ARM ERROR: architecture for ./usr/bin/firecfg is Advanced Micro Devices X86-64, should be ARM Many thanks to 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
