/usr/local/lib/gcc49/include/c++/bits/c++0x_warning.h:32:2: error: #error This file requires compiler and library support for the ISO C++ 2011 standard. This support is
currently experimental, and must be enabled with the -std=c++11 or -std=gnu++11 compiler options.

Anyone know what it wants?

Doesn't the error message say that already?

In what context do you see this?

./configure CFLAGS="-march=native" --with-crypto --with-curl

cpuminer-opt is a fork of cpuminer-multi is a fork of cpuminer that supports much more algorithms. I also tried to compile it on FreeBSD but to no avail (with another error tough). You would have to go though the code to make it work.

Read the source code. Exactly which C++-11 features does it need? I'm going to bet that those are available in CLANG, since that also supports C++-14.
