compilation of nx-libs fails on OpenBSD clang compiler

[sandeep-gh]

Using OpenBSD clang version 11.1.0 compiler for Target: aarch64-unknown-openbsd7. to compile nx-libs. It fails to compile due to type mismatch I guess. Is there a workaround/easy fix.

  if (bind(newFD, addr, addrlen) == -1)

Hmm, we are successfully compiling using clang in GitHub actions. In what file do see this line?

My bad, didn't copy the file name error message. Its in nxcomp/src/Loop.cpp.

Loop.cpp:4224:34: error: invalid operands to binary expression ('__bind<int &, sockaddr *&, unsigned int &>' and 'int')
