[SOLVED] Statically linked Qt and gfx-transformed driver
-
I'm developing an Arm cross-compiled application that is linked to Qt4.8 + Qwt statically and uses gfx-transformed drivers to rotate the screen. App is built without errors, but when I try to launch it, that's what happens:
- #/usr/bin/app -qws -display transformed:Rot270
- #transformed: driver not found
Few key points to mention:
- Qt is configured with -plugin-gfx-transformed, -static and -release flags among others (I'm using BitBake/Yocto to build it along with the whole filesystem image)
- When Qt is used as shared libraries, everything works fine.
- If I launch statically linked app without rotation, everything works fine too (except, obviously, the screen is not rotated).
I suspect the problem might be in my .pro file as I don't include gfx-transformed drivers in any way (don't know if/how to do it and can't google any related info). Any help would be appreciated, thank you in advance.

Hi,
IIRC, since you do a static build, you should rather build with qt-gfx-transformed so it's builtin your library
-
SGaist, I'll try that too, thanks. Meanwhile, I have solved my problem as described in Qt manual[1] by adding following line to project's .pro file:
QTPLUGIN += qgfxtransformed
and this above main() function:
Q_IMPORT_PLUGIN(qgfxtransformed)Not sure how I've missed that page while been googling for a solution earlier..
-
That's the question I wanted to ask first but I've only thought of writing it :-D
Don't worry, it's one of the useful document that's always missed when dealing with a static build of Qt
Since you found out how to make it work, please update the thread title prepending solved so other forum users may know a solution has been found :)
