Hello Hanno, Thanks for your thanks for you quickly replay.

I have an error compilation, I'm using nios2-linux-uclibc for my cross compilation and uclinux architecture,
the linux kernel is 2.60 but I have this error when I try to compile the library, I want to use the library as a simple client using TLS1.2
