exception_ptr, nested_exception, and future from libstdc++ are not available for architectures not supporting always lock-free atomic ints before GCC 7. Bug report: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=64735 Fix available starting from GCC 7 (not yet released): https://gcc.gnu.org/viewcvs/gcc?view=revision&revision=244051 Signed-off-by: Jörg Krause <joerg.krause@embedded.rocks> [Thomas: - directly define the value where BR2_TOOLCHAIN_HAS_GCC_BUG_64735 rather than having additional patches touching affected architectures Config.in files - add a better comment above the Config.in option.] Signed-off-by: Thomas Petazzoni <thomas.petazzoni@free-electrons.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 Freenode IRC.
