If you are not going to use C++, just compile the src/onion/ directory, and install only that (do make when at build/src/onion/). If you are going to use C++, you can use jus teh C library, or try to fix the library. Quite probably the errors are because your compiler does not support C++11 (or C++14, I dont remember which one was I aiming for). Let us know what works for you. Regards, David.

Hi,David
Yes, only compile the c file to complete the compilation process; whether you can add the compile option (-std=c++11/14), complete the compilation of cpp, if so, where to set it.

[zacharygrafton]

What version of gcc are you using? You may be able to pass the -std=c++14 option through the CFLAGS environment variable to cmake, but it's a moot point if you c++ compiler doesn't support enough of C++11.
