Newer toolchains silently fail during configure step. After some investigation, it is because -Wimplicit-int is returned for one of the simplest test from the in-package configure file and thus fail the configure step early, when checking if the compiler can produce an executable. Let's fix this by simply regenerating the configure file, similarly to what Debian is doing, c.f. debian/rules. Fixes: https://autobuild.buildroot.net/results/ff7a9c3c42f11a2ab71fb04ff0f6d593ac9ee327/ (but there are more build failures later, fixed in a follow-up commit) Signed-off-by: Quentin Schulz <quentin.schulz@cherry.de> Signed-off-by: Thomas Petazzoni <thomas.petazzoni@bootlin.com>
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.
