modjo756

today i have make another progress ! i downloaded qt creator 3.4.1 (before i take master branch). Replace botan.c and header and after many hours hours qt creator build successful !!!
New problem, now when i launch qtcreator since terminal i have this message :

pi@raspberrypi ~/opt/qt-creator-opensource-src-3.4.1/bin $ ./qtcreator
[9;0]Unable to query physical screen size, defaulting to 100 dpi.
To override, set QT_QPA_EGLFS_PHYSICAL_WIDTH and QT_QPA_EGLFS_PHYSICAL_HEIGHT (in millimeters).
No tool chain set from kit "Desktop".
No tool chain set from kit "Desktop".
EGLFS: OpenGL windows cannot be mixed with others.
Aborted

Same question, do you have a solution ? Do i need to use qtwayland to use qt app (like qt creator)

Are you running an X server on your raspberry pi 2 ?

I don't know, i had just downloaded the last debian image last week and no modification for the desktop ! If i understand i can't use more than one windows with eglfs, and it must full screen ? If i want to use X11, i need xcb plugin but i don't know if i have it, and there is no opengl support on it ? Perhaps the better solution is to use wayland ? Do you know lxQt (but for the moment no support for arm platform ...) ?

If you are running a desktop on your Pi 2 then you're likely running an X server. For the eglfs part, you can only have one top level window and the first one is forced to be fullscreen, then you can have several non-toplevel widgets. What you can't have is several GUI application running at the same time.

I can't tell if you have the xcb plugin, I don't know the configure options you used.

It depends on your application needs.

I've heard of it but it's been some times since I last read about it

Thank's for your help. i also tried to launch qtcreator with no desktop start (startx) at the login but i have the same error ... How i can set QT_QPA_EGLFS_PHYSICAL_WIDTH and Height ? For this error : No tool chain set from kit "Desktop", it's important to correct it or it's just a warning that i can resolve later ?

SGaist

export QT_QPA_EGLFS_PHYSICAL_WIDTH=XXX

The no tool chain error means that either you don't have a compiler installed, or Qt Creator didn't find one, in any case, it doesn't influence the startup of Qt Creator.

If i do this : ./qtcreator -platform xcb i can launch qt creator and use it !!! It just have a problem when i am on welcome index, i have this error, i don't know if i can resolve it. But for the rest, all is fine !!!

version
kit
designer

Now i can make my app directly on my raspberry2 !!!

SGaist

You can disable the welcome plugin when starting Qt Creator

to my experience you not only have to manually make and make install the lib folder in qt5/qttools/src/designer/src/ but also the components folder, as the content of this folder generates libQt5DesignerComponents library
