I closed and re-opened since I found It was indeed my own mistake. I was not initializing globjects properly with globjects::init(...glfwGetProcAddress...) Now I've got another segfault on Object::id(), which probably is my own mistake again. Sorry for the pollution, maybe I'll save some other newcomers the headache once I'm done!

Ok it's working, maybe it's worth keeping this issue as some noobs like myself might get confused on how to use this library. Conclusion:

• I was doing things wrong.
• This codebase is awesome.
• I must read the examples thoroughly the next time before I start coding based on a glance at a readme Sorry and thank you!

Thanks for using globjects. Although you found and presumably fixed the issue yourself, I think we can learn from this issue nonetheless:

• improve readme, especially a quick-starting guide
• Add more assertions and checks for internal state validation (only enabled in debug mode)
