gcc 4.8 on ubuntu 14.04 does some broken optimization at link-time which causes grpc to create a grpc_cpp_plugin which quits because of a failing assertion. The created plugin is itself used during compilation which lets the build fail. With the added -Wl,--no-as-needed flag the LTO is disabled and grpc compiles successfully. fixes: - http://autobuild.buildroot.net/results/b554f6f2fb66892273f7520ad6e36923557b229e - http://autobuild.buildroot.net/results/3ebb2880b9b3fd5154979016391dde897e2c039c - http://autobuild.buildroot.net/results/c2078e821e0728fe980be2c849c25d82e791a4c2 Signed-off-by: Michael Nosthoff <buildroot@heine.tech> [yann.morin.1998@free.fr: rewrap the comment] Signed-off-by: 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.
