How to restrict linking of X server libraries with an application compiled for framebuffer

[Kart]

I have build a Qt 5.9.1 kit for x86 in my host Ubuntu 16.04. My target system only have frame buffer and i am running it using libqlinuxfb plugin.

ldd myapplication gives

I want to avoid X server based library linking with my application. Can anyone help me with a way out ?

Thank you for you time.

Hi,

What options did you pass to configure ?

[Kart]

@SGaist Default configurations by the qtcreator

qmake firstx86/firstx86.pro -spec linux-g++ CONFIG+=debug CONFIG+=qml_debug && /usr/bin/make qmake_all

Edited :
Are you asking about the options passed on to the build of Qt 5.9.1 ?

[SGaist]

Yes, the one you used to build your custom version of Qt.

[Kart]

@SGaist This is my configuration

./configure -opensource -confirm-license -skip wayland -no-egl -c++std c++11 -proprietary-codecs -v -I/opt/qt/qt5.9.1x86/include -L/opt/qt/qt5.9.1x86/lib -prefix /opt/qt/qt5.9.1x86

[SGaist]

From your options I don't see anywhere that you are disabling the xcb backend.

[Kart]

@SGaist Yes i have not disbaled xcb backend. But is it possible to build an application specifically for framebuffer ? Or the build will happen for all the plugins available ?

[SGaist]

The application stays generic, it’s just the backend plugin loaded that changes.
