Error while building ZephyrOS-Firmeware with CMake/Ninja and CPLUSPLUS C++ #builds #ninja #c++ #nrf52840 #bootstrap #builds #ninja #zephyr
But there is a problem with programs that need C++, which support is activated with "CONFIG_CPLUSPLUS=y" in Config-File (https://docs.zephyrproject.org/latest/reference/kconfig/CONFIG_CPLUSPLUS.html).
When I try to build the sample ("echo_server" sample vom samples/net/socket/echo_server) with "cmake -GNinja -DBOARD=nrf52840_pca10056 -DCONF_FILE="prj.conf overlay-ot.conf" .." eveything seams to work so far:
But, when I then run "ninja" to create .hex-File I get an error:
"FAILED: zephyr/ext_proj/STamp/ot/ot-bootstrap The command ".\bootstrap" can not be found or is written wrong No patch step for 'ot'" "
I think it has something to do with my Complier and/or C++ because when I change to "CONFIG_CPLUSPLUS=n" in the .conf-File, it builds the binaries without any errors. The problem is that without C++-support I can not use some features I want to use (Openthread) because they depend on C++.
I'm using Windows 10, GNU_ARM_Embedded_Toolchain (7-2018q2) and with other Tools from the Getting Started Guide from Zephyr (Python3, pip, west, Ninja, CMake). (https://docs.zephyrproject.org/latest/getting_started/index.html)
Hope you have some ideas, thanks for your help! With best regards
