Configure QtCreator in RPi3

[Pavel_47]

Have you any idea where can I find this mkspec.

[SGaist]

Under the mkspecs folder in your Qt installation.

@SGaist
I installed Qt quite a while ago and don't remember how I proceeded at that time. I can identify QtCreator location using which qtcreator, but for framework it doesn't work. Do you have any idea how to find it ?
Thanks.

[SGaist]

Go to the preferences -> build and run -> Qt Versions.

[Pavel_47]

There is no build and run in preferences.

[SGaist]

It's Build & Run, but some stuff has changed, so depending on your Qt Creator version, it's under Kits.

[Pavel_47]

Well, I'm not sure I understood you correctly.
I've found QtCreator in Programming section of Application menu.
But neither section in Application menu mentions Qt framework itself.
The location of QtCreator executive I can check with
"which qtcreator" command.
It's located in /usr/bin. But there is no any folder named mkspec.

Please start Qt Creator, go to menu Tools > Options > Kits (or Build & Run if you have an older Qt Creator version) > Qt Versions:

There you have all your Qt versions listed and the path to qmake

Yes, I've located it. Thanks.
What about -lGLESv2 option ? I didn't find any makefile in mkspecs directory.
Only qconfig.pri, qfeatures.pri, qmodule.pri. Should I check any of them for -lGLESv2 option ?

[SGaist]

No, it's in the devices subfolder. The one dedicated to RPi3.

[Pavel_47]

There are 4 subfolders in devices subfolder that are in relation with RPi:

• linux-rasp-pi2-g++
• linux-rasp-pi-g++
• linux-rpi3-g++
• linux-rasp-vc-g++
  Inside of all these subfolder there are filses qmake.conf
  In every there are settings:

QMAKE_LIBS_EGL = -lEGL -lGLESv2
QMAKE_LIBS_OPENVG = -lEGL -lOpenVG -lGLESv2

I replaced GLESv2 with brcmGLESv2 in all qmake.conf files (i.e. in 4 folders).
Didn't help: when compiling project in QtCreator, I still see the same error message:
cannot find -lGLESv2

[SGaist]

Might be a silly question but are you sure you are modifying the one from your self-built Qt ?

[Pavel_47]

I modify those, found in the location, specified in QtCreator: Tools->Options->Kits->Qt Versions

[SGaist]

Did you check what your Kits are using as mkspecs ?
