Fixes #9576 When the path to a br2-external tree is relative, make enters an endless recursive loop (paths elided for brevity): $ make BR2_EXTERNAL=.. foo_defconfig make[1]: stat: ../configs/../configs/../configs[...]/toto_defconfig: Filename too long make[1]: *** No rule to make target '../configs/../configs/../configs[...]/toto_defconfig', needed by '../configs/../configs/../configs[...]/toto_defconfig'. Stop. Makefile:79: recipe for target '_all' failed make: *** [_all] Error 2 It is a bit complex to understand the actual technical reason for this never-ending expansion; it seems it happens in the code generated by the percent_defconfig macro. Not sure why, though... But the root cause is the relative path. Just use absolute, canonical paths to br2-external trees. Always.

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
