Compiling Qt 5 without X11 nor Wayland

[yuvalt]

Hi,

I'm trying to build Qt 5 on an embedded linux system which does not have X11 nor Wayland. It has OpenGL ES 2.0 and EGL and I was hoping to use the eglfs platform. However, when I try to run configure I get notified that I have neither xcb nor wayland and that I may disable both but it will disable graphics. So.... how can I use Qt 5 with OpenGL ES 2.0 + EGL using eglfs?

Thanks, and hope it's not a repeat question... (I did search :-))

Anyone? :-)

I've never done it myself, but I'm sure it's possible. Maybe check out the code for lighthouse-android at: http://gitorious.org/~taipan/qt/android-lighthouse Sorry I can't be of more help.

I saw this just now. I am not sure if you have already compiled. use this for configuring:

@ ./configure -prefix $PWD/install -xplatform linux-arm -opensource -confirm-license -no-xcb -eglfs -opengl es2 @

I was able to compile and run with this.

I have a question which might apply to this thread. I am trying to configure Qt5.3.2 to enable egl, eglfs, but have all X11 parts disabled.

However, for an linux open-embedded arm device, the EGL-X11 auto-detection ... () is enabling EGL-X11, but I do not want this enabled.

Do you know how do disable EGL-X11 as a configuration option?

egl-x11 is irrelevant if you are not using the xcb platform plugin. In your case xcb is disabled completely so the fact that EGL support under X11 is reported as available has no consequences whatsoever.
