Managed to install and run everything on eOS Juno on my Razer Blade laptop with QT Creator
just realised maybe a bit more details would help. installed of_v0.10.1_linux64gcc6_release with QT Creator version 4.6.1 cause i was told to. I do however want to check if later versions of QT run just as well. I followed this https://www.youtube.com/watch?v=1jdjcF7rUDU for installing QT in the first place (ignore bits of the video that dont seem relevant). Happy to help.
Thanks for the info which Razer Blade laptop are you using may i ask ?
