Issue with Cmake for the edge-impulse-standalone

I have been following the instructions for https://docs.edgeimpulse.com/docs/running-your-impulse-ecm3532 intending to eventually deploy other (non-impulse) C++ libraries on the ETA compute ecm3532 AI Sensor Board.

After running the cmake .. command I am met with the following error:

is not able to compile a simple test program.

It fails with the following output:

Any help is welcome, the issue seems to be that msvc is used as the linker/compiler, I have installed gcc and g++ and set them to be used as the CC= and CXX= environment variables, but the msvc is still used.

I have included screenshots of my environment variables targeting the CC= and CXX= variables and my path variable. Any help with this issue would be very welcome

@ando20 Could you try setting the paths in the CMakeLists.txt file? Maybe this:

set(CMAKE_C_COMPILER C:\path\to\arm-none-eabi-gcc)
set(CMAKE_CXX_COMPILER C:\path\to\arm-none-eabi-g++)

Not too well versed with CMake on Windows, but this at least is how you can always override on Linux.

Hi @janjongboom thank you for the quick reply, I have tried that method but it has not worked, I edited the line below the comment:

#Below line should point to CMakeList of project base directory(freeertos directory)
to point to the \Platform\ECM3532\M3 directory is this necessary?

Ah, so I’ve been diving into this a bit more, and the ECM3532 does not allow you to override the compiler like this, as this is later overwritten by Platform/ECM3532/M3/ECM35xx_toolchain.cmake. The best option would be to make sure C:/Program Files (x86)/GNU Arm Embedded Toolchain/10 2020-q4-major/bin is in your PATH, and from everything I can see it will then find the compiler…
