Compilation Error

[PhKindermann]

Hey,

I tried to compile your program, but I'm getting errors. First, I got a huge list of errors (I have a 800kb file that I can send you, if you want). I got rid of most of them by setting CMAKE_CXX_STANDARD to 17 in CMakeLists.txt, but one error remains:

[ 83%] Building CXX object CMakeFiles/OCM.dir/home/philipp/2024-pace-submissions/heuristic/13-kongqi/pace-2024-pace-2024/Test/TestCoreOCM.cpp.o

Do you have any idea what I can do to fix this error? I'm using Ubuntu 22.04 LTS.

OK, I got it to work, following this issue of another project that had the same problem: rizsotto/Bear#566

In GOAL/ThirdParty/Protobuf.h, I replaced line 37

options.always_print_primitive_fields = true;

by

#if GOOGLE_PROTOBUF_VERSION < 5026000
    options.always_print_primitive_fields = true;
#endif

Together with the change in CMakeLists.txt outlined above, I could now compile the code.
