Hello, I'm new to C++ so I'm not sure if I did correctly. I followed your instruction and got this error Do I need to run autoconf before ./configure make Even so, I got another problem:

./configure make configure: WARNING: you should use --build, --host, --target ./configure: line 2246: syntax error near unexpected token ,' ./configure: line 2246: AX_CXX_COMPILE_STDCXX_11(, optional)'

I guess it is due to version incompatibility?

Try ./configure and make as separate commands, not as part of the same command. You should not need to run autoconf; if you do want to regenerate the configure script, use ./autogen.sh instead.
