Project fails to build due to "Failed to find mbedtls, cannot build security libraries"

[Rob Nuttall]

Hi, i am using ncs version 1.6.1. I am able to build the project on my windows computer. A few months ago i set up a CI build on a Linux machine which also worked. However i have come to use the Linux machine again to run a CI build and run into the error when trying to build "Failed to find mbedtls, cannot build security libraries". It still works on my windows machine. It should be noted that ncs is downloaded each time before a CI build. I have also tried setting the ARM_MBEDTLS_PATH variable to the correct mbedtls path but this also doesn't work. Any idea as to what config might be wrong?

Hello, 

The technical support team will be out due to Easter Holiday until Tuesday April 19. We're sorry for the inconvenience.

How have you installed the nRF Connecct SDK on you Windows machine? Can you please provide full log output from when you receive the error in Linux?

Thanks. 

Kind regards,
Øyvind

          make gcc gcc-multilib g++-multilib libsdl2-dev
