Without std=c++11, mutex is not always correctly detected with gcc 4.7, 4.8 or even 5.x. As a result, boost_thread is wrongly selected by boost_context. mutex is available on gcc 4.7.x, the issue is that boost does not correctly detect it because -std=c++11 was missing. Keep thread select for gcc version lower or equal to 4.6. mutex is available since gcc 4.4 (with std=c++0x) but common buildroot practice for C++11 packages is to have a dependency on gcc 4.7, 4.8 or 4.9 depending on the requested C++11 features.

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
