Link to glew

[issalig]

On Ubuntu 16.04 I need to add a a link to libglew.

clang++ -O2 --std=c++14 pkg-config --cflags glfw3 view.cpp mymath.cpp -oview pkg-config --static --libs glfw3 glew

Thank you.

I must upgrade my Linux test VM to 16.04 !

Also I had to call glewExperimental and glewInit in view.cpp to make it work. It seems to be sth related to my glew version (Ubuntu 16.04, GLEW version 1.13.0, OpenGL version 3.0 Mesa 11.2.0 is supported)

    glfwSetKeyCallback(window, key_callback);
    glfwSetInputMode(window, GLFW_STICKY_KEYS, 1);
   //PATCH STARTS HERE  
   //just after creating context and before using OpenGL
   //https://stackoverflow.com/questions/8302625/segmentation-fault-at-glgenvertexarrays-1-vao
   glewExperimental = GL_TRUE; 
   glewInit();
   //PATCH ENDS HERE 
    //set gl settings
    glGetError();
    glClearColor(0.0, 0.0, 0.0, 0.0);

I've been thinking of porting over to use SDL2 rather than glfw3. I'm using that, SDL2, for other projects, and I think that would open the door to an easy Windows version of the PCB solver.

Just as issalig commented on Feb 9, 2017, my compile failed on Linux version 4.14.34-1-MANJARO
I also had to add a a link to libglew.

clang++ -O2 --std=c++14 pkg-config --cflags glfw3 view.cpp mymath.cpp -oview pkg-config --static --libs glfw3 glew

I got things to build on an Ubuntu VM after installing the libglew-dev and libglfw3-dev packages. And yes on that platforms it does SEGFAULT. So somthing to look at.

I wonder how others have managed to run it on Linux. I've never tried before myself as this was a Mac OSX project initially.

However, this makes me think I need to switch over to useing SDL rather than glfw3 as I'm not happy with glw3 even on the Mac platform.

Adding the:

glewExperimental = GL_TRUE;
glewInit();

Does make it work.

I still think I'll switch over to SDL.
