btAssert user-defined literal operator not found

[slr_555]

Hi, I am new to Bullet and trying to work my way through this tutorial https://www.reddit.com/r/ludobots/wiki/core05

It compiles without errors but when I try to run it I get a breakpoint with "user-defined literal operator not found" underlining btAssert in all dependent files. I started with the RagdollDemo App and modified it. Here is my code:

Hi,

Cool thing you are working yourself through the ludobots tutorials! They are very great and I even created an upcoming bullet physics browser example inspired by them (here: https://github.com/bulletphysics/bullet3/pull/723).

1) First some basic questions: Did the example browser work before you started to modify it?
2) Are you using anything from C++11? Because the compiler apparently thinks you are. http://en.cppreference.com/w/cpp/language/user_literal
Bullet itself does not use anything from there, so it must be you who triggered it. Also I never heard of btAsset, did you implement this? I can not find btAsset in the bullet repository. Do you by chance mean btAssert?

Cheers

Thanks benelot but I got it working, and yes I did mean assert haha. I have a new problem though, maybe you could help me with it instead?

Great that you could fix this. What was the issue that caused the strange error message? I will look into the other thing.
