CUGL Bug Patches

CUGL is continually a work in progress. Every time we work on a lecture we either find some issue, or some way in which the engine can be improved. While we try to feature lock the engine at the start of the semester, that is not always possible.

This page is where we will post the mid-semester patches. For each file you should simply copy it to the correct directory. Source code files replace the appropriate file in cugl/source. Header files replace the appropriate file in cugl/include/cugl.

In addition, this semester we will always update the download link to CUGL after a patch. So you can get all the benefits of a patch simply by redownloading CUGL.

Patch 4.0.1 (February 4, 2026) Do Androids Dream of Electric Bugs?

In preparing the third individual assignment, we discovered several problems with the Android build system. These include

• Improper detection of SIMD support when integration WEBP
• Improper detection of OpenSSL when building the network package

Fixing these required extensive changes to the template folder, so there are no individual files to download. Instead you should just redownload the latest version of CUGL from the engine page.
