Trouble compiling cpp to exe

[MSLewis522]

I am using visual code studio to try to run the real-time-hand-tracker.cpp
I have downloaded all of the folders from git and then I tried to build the .exe file with g++ compiler from mingw64. however this failed with a very very long list of errors and attempts to fix - after reading through the messages from the failed build, I think it is having trouble locating the right find_json() function frequently throughout the program.

I will paste the entire message below. Any help would be very much appreciated ! Thanks so much !

Update: I have similar issues whenever I try to build anything from these folders. (openvr demo, synthetic hand tracker, etc)

[melax]

Errors like that certainly aren't obvious. One possibility... microsoft visual c++ (msvc) tends to be more forgiving about the ordering of overloaded template function. trying msvc with stricter conformance mode (/permissive- flag), attempts to compile generate similar error messages. To fix... Moving the serialization support for the linalg types (float3, int2, etc) to put them right inside of the json.h, to solved this problem.

can you try grabbing the two json related header files in the attached zip and replacing the existing versions in the hand_tracking_samples/third_party/ subdirectory?

Ah ! You're a complete lifesaver!
But.... different errors now </3
looks like its having trouble with the temp files created while trying to run the .exe version of the realtime-hand-tracker.cpp

Wait sorry not run the .exe, these are the errors when trying to build the exe from the cpp

[melax]

These look like link-time errors, and seem to indicate it is not finding the opengl library. I'm not as familiar with g++. Perhaps you need to add -lGL on the command line so it will link with the opengl library. Start first with trying to compile and run the synthetic hand tracker demo program. other than opengl, it doesn't have additional dependencies. It doesn't need the realsense camera (and associated library) since it creates a fake depth map from rendering to the z-buffer, so For all the programs, in an effort to hopefully compile out of the box on PCs and maximize compatibility, the source code only uses opengl version 1.1 (opengl red book) function calls. Also, when compiling the source, you may want to add a flag to optimize the code, -O, so it isn't painfully slow.

An alternative suggestion... From the filenames in the error message above, it looks like your on a PC Windows system. Have you tried just using visual studio (such as visual studio community 2019 free version), which uses the Microsoft visual c++ (MSVC) compiler? Is that an option? then the project files ( .sln and .vcxproj files) include any library dependencies.
