Re: Compilation issue ( v1.1.1 )

OCIO 1.1.1 does not support C++ 11. The RB-1.1 branch _can_ compile with C++ 11, but it is not officially supported. It was mostly updated to support linking against OIIO 2. OCIO 1.1.1 ships with a supported version of yaml-cpp, which should be built and linked automatically unless you're passing the  USE_EXTERNAL_YAML CMake option, but you will need to use the C++ 98. OCIO v2 supports C++ 11 and 14.

Okay, I found out what is wrong.  The YAML library is getting compiled
with std::cxx11 strings and libOpenColorIO is not. However I don't yet
know how to force either of one to compile in the same abi as the
other.   I've so far tried:

export CXXFLAGS=-std=cxx11
export LDFLAGS=-std=cxx++11

export CXXFLAGS=-std=gnu++11
export LDFLAGS=-std=gnu++11

export CXXFLAGS=-D_GLIBCXX_USE_CXX11_ABI=1

all with no success.
