Nim enum issue

[Riku5543]

Hello! I just recently picked up Nim and wanted to use glad for opengl bindings. When I import the gl.nim file though, I get this error. (Generated OpenGL 3.3 Core with "Generate a loader" checked.)

gl.nim(107, 39) Error: -1 can't be converted to uint64

I peeked at the code, and it's in the section dealing with opengl enums.

In C, -1 as a 64-bit unsigned int is equal to the maximum value of a 64-bit unsigned int (it wraps around). That doesn't solve the problem, but I hope it gives it some context.

Thanks @Dav1dde

@Develon5543 Can you please give me some details? Which Nim version are you using, is it the latest 1.0.6? Can you give me the exact parameters you used for generating the GL file?

[Riku5543]

@johnnovak Yes, I'm currently using Nim 1.0.6. To generate the GL file, I went to the website and selected the language Nim. I kept the specification as OpenGL, set the gl api to 3.3, and picked the Core profile. I kept the other apis set to None, and didn't enable any extensions. The only option I checked was "Generate a loader". That gave me a zip file that only contains gl.nim which is what I was having issues with.

Thanks, I'll have a look today or tomorrow. I remember I had this issue before but I thought I fixed it. Anyway, I'll fix it better if it's still an issue :)

Ok, it turns out my memory is not so bad and I did fix this a while ago:

The problem is that the webservice is running a version earlier than this commit. This has been confirmed by comparing the output of the webservice with the output of the current master version running locally.

Solution: @Dav1dde please update the webservice to use the latest master version.

In the meantime, you can clone the repo, check out the master branch and run the following command locally to get what you need:

python -m glad --extensions , --spec gl --api gl=3.3 --profile core --generator nim --out-path out

Alternatively, you can just change the following two const values manually to this:

  GL_TIMEOUT_IGNORED*: uint64 = 0xFFFFFFFFFFFFFFFF'u64
  GL_TIMEOUT_IGNORED_APPLE*: uint64 = 0xFFFFFFFFFFFFFFFF'u64

Thank you so much, @johnnovak! I'll manually edit the files this time. Thank you for your help.

I updated it just now:

Sorry about that, I must have previously updated glad2 instead of glad on accident.

Thanks for looking into it @johnnovak
