Since Buildroot commitdcee99507cthat bumped package/icu to version 77-1, the build of cppcms with ICU support enabled fails. Indeed, ICU now requires C++17, and while cppcms.mk has some logic to get C++ flags using icu-config, the -std=c++17 gets ultimately overridden by the built-in -std=c++11 flag encoded in cppcms CMakeLists.txt. To fix this, we have submitted a patch upstream that ensures the CMAKE_CXX_FLAGS passed on the command line take precedence over the built-in flags defined in cppcms CMakeLists.txt.

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.
