@aha_1980 said in Project ERROR: Cannot run compiler 'clang++': You usually get *.pro.user.16fe832 files if you copy the project to another machine and open it there without deleting the .pro.user first. ...yes. I suppose that's a missing piece of information. The machine I developed on couldn't properly report to github, so I copied it to a flash drive.

@jsulm got it got it . Thanks .

@Avec Oh duh.. I should have thought of that as a potential reason. I just assumed that you were in the directory with the files as your current dir. Glad it's all solved. :)

Thanks a lot. :) @raven-worx @giupigna. Problem solved.

@beginMyCoding Did you tried the at() ? you can get the particular element at a specific position from QStringList using at() for example , in your code images.at(index) will give the element

@Ratzz Did you use a relative path. And I've solved another way thanks

Hi, From a quick look at the setting up page, are you including the sources of QCustomPlot in your project ?

@SGaist Thank you once again! Now, I can manage to display the folder list inside the stacked widget page using QTreeView + QFileSystemModel combo!
