Gurobi with C++

Question

This is not the right question to be posting here, but is anywhere a video tutorial/ written on how to link C++ header files with Gurobi?

Answer 1

On macOS, you can find a Makefile inside /Library/gurobi950/macos_universal2/examples/build to compile all examples. Open the Terminal.app and enter the following:

# change the directory
cd /Library/gurobi950/macos_universal2/examples/build

# compile and run all c++ examples
make run_c++

This will compile and run all c++ examples. If you want to compile a specific c++ example, you only need to include the gurobi header and link to the gurobi library. Let's take mip1_c++.cpp as an example and let's take the clang++ compiler:

# define bash variable for Gurobi's path
GUROBI_HOME="/Library/gurobi950/macos_universal2/"

# change the directory
cd $GUROBI_HOME/examples/c++

# Compile the program
clang++ mip1_c++.cpp -I${GUROBI_HOME}/include/ -L${GUROBI_HOME}/lib -lgurobi_c++ -lgurobi95 -o mip1_c++

Then you can execute the program inside the Terminal.app by ./mip1_c++. Last but not least, if you're working with C++, it's highly recommended to make yourself familiar with Makefile-Generator tools like CMake.

Answer 2

There is a dedicated section about C++ programming with Gurobi in the official documentation.

There is also a CMake example in the Gurobi Knowledge Base.
