Problem with ZephyrOS build and CMake (CPLUSPLUS C++)

[gabbas1]

Hello,

I want to build firmware with ZephyrOS for nRF52840. I set up the toolchain (on Windows) and everything works so far (Pyhton, West, CMake..). I can even build the most programs with "cmake -GNinja -DBOARD=nrf52840_pca10056".

But there is a problem with programs who need C++ (CONFIG_CPLUSPLUS=y). When I try to build the "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:

"The command ".\bootstrap" can not be found or is written wrong"

 

I thing it has something to do with my Complier and C++ because wenn I change "CONFIG_CPLUSPLUS" to "n" in the .conf-File for CMake it builds the binarys with no errors. The problem is, that without C++-support I can not use some features I wanna use (Openthread), because they depent on C++.

I'm using GNU_ARM_Embedded_Toolchain. I set Environment variables like this:

I also tried to install C++ runtimes but nothing happened.

I work with Windows 10 and with Tools like in the Getting Started Guide from Zephyr (Python3, pip, west, Ninja, CMake).

Hope you have some ideas, thanks for your help!

 

With best regards

Sebastian

The issue seems to be related to the command ".\bootstrap", and more specifically ".\". I did some testing and this command is not supported in the standard cmd. Try using Powershell, where it is supported.

Hello Simon,

thanks for your help.

In the meantime i set up a Linux-System (Ubuntu) and installed the toolchain for it. When building the same sample (/sample/net/sockets/echo_server)  with Ninja in the the terminal I get an similar error:

(other samples like the hello_world work with no errors)

So I think it has nothing todo with my installation since the error occures on windows and Ubuntu. Nevertheless I try out powershell later and will report.

Best regards,

Sebastian
