Hi,

I am very new to wolfSSL and security in general. Currently I am trying to integrate version 5.5.4 of wolfSSL into proprietary 32 Bit Embedded OS. This is more of a feasibility check of wolfSSL compatibility with our OS before we move on to adopting it. I have tried integrating root wolfSSL directory and did all the basic configurations as needed. I have also enabled WOLFSSL_LWIP. Looks like there is no issue with the compilation but I am facing some linker errors. I do see the file inclusions happening as expected and not sure why this is happening. Can you help me undertstand what is going wrong over here? I will share the build log.

Also will I be able to use your client /server example projects directly? What kind of modifications are expected to make it work with my proprietary OS? Any documents or guidance will be appreciated.
