Yes, they look okay. What I don't understand is that the flag -std=c++0x is defined in DOLFIN_CXX_FLAGS in DOLFINConfig.cmake and DOLFIN_CXX_FLAGS is added to CMAKE_CXX_FLAGS in the CMakeLists.txt for the demo, but still the flag is not added when compiling the demo. Just to be sure, can you run the following commands in the C++ poisson demo directory?
rm -rf build mkdir build cd build cmake .. make VERBOSE=1 Then post the output from the make command here.
