Hello,

Here on Ubuntu 14.04 Indigo with g2o (ros-indigo-libg2o), I have only this warning when building Graph.cpp:

[  8%] Building CXX object corelib/src/CMakeFiles/rtabmap_core.dir/Graph.cpp.o

You have errors about "std" namespace not found. What s your GCC version? Here mine:

$ gcc --version
gcc (Ubuntu 4.8.2-19ubuntu1) 4.8.2
