Homebrew Citro3D and the new updates

[MadClaw]

I'm working on a project with Citro3D and I'm having trouble compiling when I run into tex3ds from the recent library updates.

Specifically the first error to show up is:

source/citro3d/include/tex3ds.h:79:92: error: unknown type name 'decompressCallback'; did you mean 'ndspAuxCallback'?

This should be easy to fix, missing dependency?

Any ideas welcome

It is not obvious from your post that you are trying to build citro3d rather than your own project. This appears to be an issue with the master branch on the citro3d repository. Either use the version of citro3d that comes with the devkitpro installer or create an issue on the citro3d repository about the build process. It looks like an include is missing in tex3ds.h to pull in the decompressCallback definition from ctrulib when building citro3d. I am not sure that the master branch is guaranteed to be build able so you may be on your own trying to build from source.

Ah, I wasn't sure. I noticed the examples were updated to run under the new changes and I assumed it was ready. Thanks for the reply!

There's no need for you to compile citro3d from source and in fact it's better if you don't.

Please use pacman to obtain updates.
