Hello, I have encountered an issue where libcoap cannot be compiled using the minGW compiler on Windows 10 system! My minGW compiler was downloaded and installed through MSYS.
Does libcoap not support compilation with minGW on Windows?
I used the mvsc compiler and it worked, it passed.
I need help, I need help, thanks a lot!
