Welcome to the wolfSSL Forums!

Sorry for the late response, Kareem. Thank you. Its a non-commercial, research-oriented project. My intention is to experiment with wolfSSL TLS1.3. I'm also interested in using wolfMQTT.

" It looks like in this case it is trying to execute the static library directly, which is not valid." -- Yes! This was the case.

"I do see that you've commented out $(SIZE) in the build_static rule, can you elaborate on why you've done this?" -- I commented out the size because my arm-none-eabi/bin/ does not have it, as shown in the attached image, but failed to realize it would cause a problem. The issue was solved by installing arm-none-eabi-binutils (which includes arm-none-eabi-size), then setting its path and uncommenting the lines in Makefile.common. After this, my output was:

Again, thank you so much for your response, and I'm sorry for the trouble.

Hello, hope to find you well. I'm new to embedded development, so I'm sorry if what I'm asking is out of place. I'm trying to build wolfSSL targetting the Nordic NRF52840 microcontroller.

However, after I run make, at the final stage I get the following error:
