Hi,
I'm trying to use the mbedtls library on my application. When I add the needed header files, my application can not build due to "undefined reference" errors. I have developed my application on my Linux host system, but I do not know how to compile the libraries for the XDK. There is a printscreen of my application on attachment. Can someone guide me into compiling with this library? Thanks in advance.
