@yago, When I run it, it connects successfully and says it logged in, but then says "Illegal instruction (core dumped)" and exits. Would you know why?
I have tried:
make CFLAGS="-O3 -march=native"
make CFLAGS="-O3 -march=corei7"
make CFLAGS="-O3 -march=generic"
make CFLAGS="-O3"
All create a binary that gives the same error.
