cf_gen.cc is compiled by host compiler and unconditionally uses auto since bump to version 6.6 in commitc13199c932and09835feb25resulting in the following build failure with host gcc < 8: /usr/bin/g++ -O2 -I/home/buildroot/autobuild/run/instance-1/output-1/host/include -o cf_gen ./cf_gen.cc -I. -I../include/ -I../src ./cf_gen.cc: In function 'int main(int, char**)': ./cf_gen.cc:268:63: error: forming reference to void auto &newEntry = entries.emplace_back(name); ^ So add a dependency on host gcc >= 8 and gcc >= 8 as advocated by upstream in9d3433c4ac/doc/release-notes/release-6.sgml.in: This release adds a dependency on C++17 support in any compiler used to build Squid. GCC 8+ and Clang 8+ support C++17. While at it, drop BR2_TOOLCHAIN_HAS_GCC_BUG_64735 which is always false with gcc >= 7 Fixes:c13199c932- http://autobuild.buildroot.org/results/f1766d1a3b2ce7745fa23cdeae1101806cd97aea Signed-off-by: Fabrice Fontaine <fontaine.fabrice@gmail.com> Signed-off-by: Peter Korsgaard <peter@korsgaard.com> (cherry picked from commitb8db5c4660) Signed-off-by: Peter Korsgaard <peter@korsgaard.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 OFTC IRC.
