Can't figure out how to install a C++ library (GLUI) on linux Mint

Question

I have been trying forever to install this: https://github.com/libglui/glui on my Linux mint distribution. I usually install stuff with the command line, and am a novice at manually installing libraries. Basically, I download the Github repo, ran the make file, and was not sure where to go from there. They don't really provide any instructions that I can find.

Basically I ran make and it generated a .a file. I moved this .a file into my /usr/lib/x86_64-linux-gnu folder. Now when I run this:

g++ -o test test.cpp /usr/lib/x86_64-linux-gnu/libOpenCL.so -lGL -lGLU -lglut -lglui -lm -fopenmp

instead of getting my previous error (/usr/bin/ld cannot find -lgui) I get this wall of doom:

/usr/bin/ld: /tmp/ccvdD4zb.o: in function `InitGlui()':
sample.cpp:(.text+0x10d4): undefined reference to `GLUI_Master_Object::create_glui(char*, long, int, int)'

collect2: error: ld returned 1 exit status

Obviously I need to do something else with that repo I downloaded and ran the make file for, I just have no idea what and can't seem to find an answer anywhere, please help!

Try `-lOpenCL` instead of `/usr/lib/x86_64-linux-gnu/libOpenCL.so` — kiner_shah, Jun 01 '22 at 05:44
Also, try putting the options before the .cpp source file, sometimes that causes these undefined reference issues. — kiner_shah, Jun 01 '22 at 05:45

If you look at the project history, commit 936b3d7e6a42c6eab0eecc191861b0a98fa7fc30 (30 Jun 2017) replaced all the mentioned functions with functions that take a const GLUI_String&.

You have apparently picked up a glui.h file somewhere that references the old interface. You should instead copy the glui.h file from the repo to /usr/local/include/GL/glui.h and add -I/usr/local/include to your compile flags. That will make sure the header matching the library is selected and you do not get these errors.
