Running a Qt application in raspberry pi without installing the framework in the device.

Alvaro Denis

Hello I am currently able to build Qt for Raspberry Pi-3 following some internet tutorials(no matter which one):
configure -opengl es2 -eglfs -no-gtk -device linux-rasp-pi-g++ -device-option CROSS_COMPILE=$RPI_TOOLCHAIN -sysroot $RPI_SYSROOT -opensource -confirm-license -debug -make libs -prefix /opt/Qt4Pi -skip qtwebengine -no-use-gold-linker

,all of they "requiere" a -sysroot parameter to be used, so when I run make install, it install the framework in the pi file system, so I umount it and put the sd in the pi, now if I want to use the Qt4Pi framework I can not configure it because I was instaled it in the target system, not in the host(my working PC)

What I want:

Build Qt with -static linker flag, to run my qt App in the device without qt installed. Is it possible?
Install Qt4Pi in my host to configure it in qtcreator as another build set.
Some one can tell me why in recent qt versions I need to use -no-use-gold-linker
Know If is possible to use all QML features without qtwebengine.
Know if make sense(is possible) build Qt for Pi without a pi filesystem "reference"(-sysroot).

For a major question(install in my host), use -extprefix and -hostprefix, see more with configure --help or follow this link:

For other opinions, I keep the question open.
