Click the badge below to see the currently confirmed issues with QLC+. Perhaps you can find a solution?
Compilation guides and platform-specific instructions are available in our GitHub Wiki.
If you're regularly updating QLC+ sources with git pull, you may encounter compiler warnings, errors, or unresolved symbols. We strive to keep the master branch free of critical errors; however, dependencies between objects can sometimes cause issues, requiring a full package recompilation rather than just updating recent changes.
We welcome contributions from the community to help make QLC+ even better. If you're working on something major, start a thread in the Development Forum first. Make sure you read the CONTRIBUTING.md document for more.
If you're reading this we already appreciate you. If you're just getting started with lighting you have absolutely no obligation to give us money. When QLC+ opens up revenue opportunities for you, we'd be very thankful for your support. GitHub sponsors is the preferred option.
If you're interested, QLC+ also has an official store where you can purchase clothing, themes, the Raspberry Pi image or one-on-one consultation with an expert.
QLC+ owes its success to the dedication and expertise of numerous individuals who have generously contributed their time and skills. The following list recognizes those whose remarkable contributions have played a pivotal role in building QLC+.
