Qt unable to locate image formats plugin?
-
I'm try ing to display .tif files for a project so I need to make use of the image formats plugin. Qt won't let me do this however, and it seems like it can't find the plugin on my computer. I have verified that the imageformats dir exists so I believe the problem might have to do with my environment variables. I only have the Qt installation dir added to path and nothing else. Chat GPT tells me I need to have a QT_PLUGIN_PATH variable somewhere but I'm unsure where. If anyone could show me their environment variables related to Qt or maybe think of another possible fix I would really appreciate that!

Deploying and running Qt applications should not involve changing environment variables.
You can temporarily set environment variables for troubleshooting, however. To investigate further:
- Set the environment variable
QT_DEBUG_PLUGINS=1 - (If you're on Windows and you're not running your application from Qt Creator) Run DebugView: https://docs.microsoft.com/en-us/sysinternals/downloads/debugview
- Launch your application
- Look at your debug output to see where it's trying to load plugins from
- Set the environment variable
