Ah yeah, I forgot to turn that off. I have an env file that switches to |
| 18 |
gcc-6.4.0 for use with old standalone packages that don't support 7.2.0 |
| 19 |
yet (I really don't use it anymore nowadays though). |

Anyways, this leads to the exact same error, so I'm inclined to think it |
| 24 |
has nothing to do with gcc versions. I was however concerned about Qt versions |
| 25 |
clashing (4 vs 5?). |

In fact, I just double-checked qtchooser, and this is the output: |
| 28 |
|
| 29 |
$ qtchooser -l |

qt4-i686-pc-linux-gnu |
| 34 |
qt4-x86_64-pc-linux-gnu |
| 35 |
qt4 |
| 36 |
qt5-x86_64-pc-linux-gnu |
| 37 |
qt5 |
| 38 |
|

Does this mean Qt4 is prioritized over Qt5? That would be a problem in |
| 40 |
this case, right? |
