With gnuradio 3.10 boost/filesystem was replaced by std::filesystem. This feature was introduced with gcc 8 (requirering -lstdc++fs (with gcc 9 explicit -lstdc++fs is no more explicitely required)). With gcc < 8 build fails with error: In file included from /home/br-user/work/instance-0/output-1/host/aarch64_be-buildroot-linux-gnu/sysroot/usr/include/boost/dll/runtime_symbol_info.hpp:11:0, from /home/br-user/work/instance-0/output-1/build/gnuradio-3.10.4.0/buildroot-build/gnuradio-runtime/lib/constants.cc:16: /home/br-user/work/instance-0/output-1/host/aarch64_be-buildroot-linux-gnu/sysroot/usr/include/boost/dll/config.hpp:42:10: fatal error: filesystem: No such file or directory #include <filesystem> ^~~~~~~~~~~~ compilation terminated. Add a dependency to gcc >= 8. BR2_TOOLCHAIN_HAS_GCC_BUG_64735 only affects gcc <7, so we drop it. Adding this restriction on gcc >= 8 also covers the dependency for volk, which requires gcc >= 7, which was not propagated to gnuradio so far. Tested with bootlin toolchain 2020.02-2 (gcc 8.3.0) Fixes: - http://autobuild.buildroot.net/results/6a82605c58f9ef9eb6c14603777dd8523dd00aa5/ - http://autobuild.buildroot.net/results/c7c4ae76954e388ab639b39fd521d90acfe4edc9/ Signed-off-by: Gwenhael Goavec-Merou <gwenhael.goavec-merou@trabucayre.com> 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 OFTC IRC. If you would like to contribute patches, please read https://buildroot.org/manual.html#submitting-patches
