With Microblaze Gcc version < 8.x the build hangs due to gcc bug 85180: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=85180. To avoid this problem, until now, ffmpeg could not be selected on Microblaze. However, this problem only happens due to optimization, and can worked around by forcing -O0. So, when BR2_TOOLCHAIN_HAS_GCC_BUG_85180=y, this commit: - adds --disable-optimizations to FFMPEG_CONF_OPTS - passes -O0 to CFLAGS in FFMPEG_CONF_ENV Then, we remove 'depends on !BR2_microblaze' from Config.in to re-enable the package. Note that the comment was talking about gcc bug 71124, but this gcc bug is a duplicate of 85180. Since all Buildroot packages now use the reference to gcc bug 85180 and the option is named BR2_TOOLCHAIN_HAS_GCC_BUG_85180, we use this naming as well for ffmpeg.

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.
