Mostly Ubuntu/Linux posts but here are some potentially helpful links:

- My [previous post](https://community.mrtrix.org/t/random-qt5-plugins-linking-issue/5875) on ensuring the Qt5 plugins path is available. TL;DR set an environment variable called `QT_PLUGIN_PATH` to the qt5/plugins filepath.
- In this [previous post](https://community.mrtrix.org/t/error-linking-qt-application/1690/15) where multiple people had the linking error reported, there are a few different things that fixed their issues:
  - Install the qt5/openGL libraries, including the dev versions
  - Make sure you don’t have a conflicting version of Eigen3 installed
  - Alternative library to install: `libglvnd-dev`
  - If you’re using an NVIDIA card, the person from that post found that there was a `libGL.so` linking issue related to their error - follow their steps to set the right symbolic link target at the correct location.

- Further debugging:
  - Paste the `configure.log` file which may have a better description of your error for people helping out.
  - Run `ldd` on `mrview` to understand where the libraries live.

- Mac-specific debugging: [Error during compilation: "error linking Qt application" - #11 by joely](https://community.mrtrix.org/t/error-during-compilation-error-linking-qt-application/1001/11)
