问题
I would like to use Gurobi in a C++ project I have in Eclipse. I tried multiple manuals/tutorials (including THIS on how to do the same in Visual Studio) to add the hook up the Gurobi files with Eclipse/GCC, but I just couldn't make it work. I feel like I don't understand enough how these things should work in the first place.
In my Gurobi folder I have 3 folders, that in my opinion are important: include (with .h files), lib (with .lib files and NO .so or .a files) and src (with .cpp & .h files).
include: I added the path to this folder to C/C++ Build -> Settings -> GCC C++ Compiler -> Includes -> Include paths, I guess this is for the compiler to see the .h files. I also added it to C/C++ General -> Paths and Symbols -> Includes -> Include directories, I guess this is for the linker to see the .h files.
lib: I first added the folder path to C/C++ Build -> Settings -> MinGW C++ Linker -> Libraries -> Libraries (-l), however after searching online it seems to me this option only works for libraries with standard names and extensions. It also gave me the error ld.exe: cannot find -lc:/gurobi900/win64/lib/, so I deleted it and added the two .lib file paths separately to Miscellanous -> Other objects.
I got to the point where #include "gurobi_c++.h" works, however, already Eclipse underlines a line where I am defining a GRBEnv() object, that is declared in include/gurobi_c++.h, but defined in src/cpp/Env.cpp. Also if I try to compile, I get undefined reference errors. This means neither the Linker nor the Compiler can see the definition of GRBEnv().
Is there a way to tell the linker/compiler where the .cpp files are? Is it happening automatically, based on the path of the include folder? Am I supposed to link the .lib or the .cpp files?
I would greatly appreciate even if someone just pointed out mistakes in my understanding.
