Recipe for a toolchain with static qt build

Recipe for a toolchain with static qt build

[Isaac Nickaein]

Hi,

I've successfully built a toolchain with Qt support using:

bitbake meta-toolchain-qte

And cross-compiled a Qt program. Thanks Yocto for that!


As the built Qt is static, I currently have to copy Qt library
dependencies (e.g. libQtGuiE.so) to the rootfs by hand (is there a
better way?)

Is there any meta-toolchain recipe for Qt static build? I hope that
help me to save a little more space, since the linker will remove
unnecessary codes from each library.

I am not following your view here. What are you intending to accomplish?

I am looking for a way to reduce size of my Qt application binary.
Statically compiling the program will result an overall smaller
output.

For instance, I have to copy the whole QtGui.so, QtNetwork.so, etc,
even when I am using very small part of them. However, in static
compilation the linker can eliminate unnecessary codes from the
output.

I am also curios that how it can/should be done to best honest,
