Unable to compile external/solver about deepcut HOT 3 OPEN

This particular error is caused by using a wrong version of the GCC compiler. I believe this has to do with the ABI interface changing with later versions of C++.

The Gurobi website lists gcc-4.6 as the latest supported[0], though the solver library clearly needs a newer version because it specifies the -std=c++11 option in CMake, and not -std=c++0x which is what gcc-4.6 supports. The gcc-4.8.1 compiler is first that supports the -std=c++11 option[1], and will get rid of the above linker error.

Assuming you run Ubuntu, you can sudo apt-get install g++-4.8 to get the latest 4.8 compiler. Following that, you must adjust your CMake invocation to:
cmake . -DGUROBI_ROOT_DIR=/home/gerjo/gurobi603/linux64 -DGUROBI_VERSION=60 -DCMAKE_CXX_COMPILER=/usr/bin/g++-4.8 -DCMAKE_C_COMPILER=/usr/bin/gcc-4.8

Setting -DGUROBI_ROOT_DIR to your installation.

I also hasten to add, that I'm using Gurobi 6.0.3 which you can acquire here (requires login). Not sure if that makes a difference, but the version number seems to match the one given in the build instructions under step 4.

Perhaps the repository maintainer, @eldar, can comment on which GCC version to use exactly?

Thank you, Gerjo. I had the exact same problem. Your solution worked for me.

@Gerjo Thank you Gerjo for your nice advice! Really works for me using default gcc and g++ 5.4.0 in Ubuntu16.04. I installed g++ 4.8.0 and it really helps a lot!
