Is "libegl warning: dri2: failed to authenticate" error significant in QtCreator?

[Injunear]

I have QtCreator installed on a Raspberry Pi 3 and I am developing on it directly. When I start QtCreator from a terminal on the R_Pi desktop I get "libegl warning: dri2: failed to authenticate" and "No tool chain set from kit R_Pi_Desktop" and then QtCreator starts up and runs as expected.

I can edit my GUI in QtCreator but am unable to build and run the edited version. It runs a previous version instead.

Can I ignore the warnings listed when QtCreator starts up or are they significant. Are those errors causing my inability to build and run GUIs, or are they unrelated?

I have searched for possible solutions but nothing appears relevant.

Thank you for your help.

Hi and welcome to devnet,

What distribution are you running ?
Did you compile Qt / Qt Creator yourself ?

[Injunear]

I am using the 2017-01-11-raspbian-jessie image.

I got qtcreator on the R_Pi 3 by typing:
sudo apt-get install qt5-default
sudo apt-get install qtcreator

I suppose this means I did not compile qt Creator myself.
To run qtcreator, I open a terminal from the R_Pi desktop and type qtcreator.

Indeed, you didn't build anything.

Then what error are you getting when trying to build your application ?

[Injunear]

The compile output has no errors. When I try to run the GUI I get the libEGL warning again then a previous version of the GUI shows up.

What do you mean by previous ?

[Injunear]

I have figured out the issue with running the previous version of the GUI. I wasn't setting things up correctly. That just leaves the question in the title. Thank you for your help so far.

I'd say that if everything is running correctly, keep an eye on it but continue developing :)
