TSLIB plugin compilation
defrag last edited by A Former User
Hi to all,
I would to know how to add the TSLIB plugin in an existing Qt 5 setup, without recompile everything from the sources.
I tried several guides to natively compile QT5 on RPI2 , like https://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi, without success. Currently I'm using the lib downloaded from https://twolife.be/raspbian/, but they do not provide tslib plugin, theoretically a "plugin" should be added without library recompilation.
Do you know if there is a guide that works or an image available with Qt 5 with eglfs + tslib for rpi2?
Thank you in advance
Hi and welcome to devnet,
One thing you can do is build it by hand. If you did an insource build, just go to the
qtbase/src/plugins/generic/tslib/folder and call qmake + make/make install. Depending on where your TSLib files can be found, you may have to give some additional informations to find them, but basically it should work.

Thank you for the reply, I managed to compile the tsib plugin in Qt5.3.2 but I have another problem, at the first touch event the application crashes without give me any information (i.e. segmentation fault or whatever). Nonetheless the tslib tool such as ts_calibrate & ts_test work without problem.
Just to make a brief overview, I compiled natively the tslib plugin, then I downloaded the kergoth tslib, compiled it and configured as described in https://wiki.qt.io/Native_Build_of_Qt_5.4.1_on_a_Raspberry_Pi.
I would like to get some information about the application crash, just to understand what I did wrong. I think that soon I will try to cross compile the new Qt5,6 lib, following the relative guide.
You should run your application through the debugger to see where it fails exactly

@SGaist I'm getting "Project ERROR: Library 'tslib' is not defined." during this step.
