The problem about GCC's version

[Caramello]

Hi，Mihai!
yeah..It's me.I get the new dataset and continue to build my project.But,when I go to the last step,"make -j4" in the fold named"build" in dynamicfusion. Get this Error:
/usr/include/c++/5/bits/stl_tree.h(1440):error:identifier "_Compare" is undefined.

First i make ,find that need my GCC'version>5. so, i update my gcc.Then, the cuda send that need my gcc <4.9......I ask my friend and comment out the Error config.h of cuda to use gcc5.Finally,i get this ERROR and don't know how to do....Can you help me again?......Thankyou!

This is highly dependent on your cuda version and what compilers it accepts (e.g now I'm using cuda 9.2 with gcc-6 as a host compiler but gcc-8 for the rest)
What you can do however is set your compiler to gcc-5 or what you are using at the moment and then set the CUDA host compiler in your main CMakeLists.txt like so:
set(CUDA_HOST_COMPILER "/usr/bin/gcc-4.9") # change gcc version and path as appropriate

Hope this helps!
