- | [[http://automon.donaloconnor.net/installing-tslib-and-calibrating-it/83/|Installing TSLib and Calibrating it]] | + | ===== Tslib compilation on a host ===== |
+ | //Tested on a Ubuntu 12.04 host// | ||
+ | |||
+ | Download the tslib sources: | ||
+ | <code> | ||
+ | git clone git://github.com/kergoth/tslib.git | ||
+ | </code> | ||
+ | Cross-compile them and install to default destinations as per tslib configuration: | ||
+ | <code> | ||
+ | ./autogen.sh | ||
+ | ./configure --host=arm-linux-gnueabihf | ||
+ | make && sudo make install | ||
+ | </code> | ||
+ | From now you can link your application or libraries agains the tslib but it is not possible to run ts_ - utilites like ts_calibrate because they are arm-binaries, not for x86 architecture. | ||
+ | |||
+ | Default destinations are: | ||
+ | * include folder for gcc include path -I<path> is '/usr/local/include' | ||
+ | * lib folder for gcc link path -L<path> is '/usr/local/lib' | ||
+ | ===== Tslib compilation on a target ===== | ||
+ | This tutorial was tested on a Ubuntu ARM Core distribution installed on a Somiqboard. | ||
+ | |||
+ | 1) download sources to a host as described in the previous paragraph and upload them to the target | ||
+ | |||
+ | 2) compile sources by a native gcc compiler installed on the ARM Ubuntu distribution: | ||
+ | <code> | ||
+ | ./autogen.sh | ||
+ | ./configure | ||
+ | make && make install | ||
+ | </code> | ||
+ | |||
+ | You can now run ts_* utilities like ts_calibrate or ts_test. | ||
+ | |||
+ | Default destinations are: | ||
+ | * ts.conf is in '/usr/local/etc' | ||
+ | * pointercal file is in '/usr/local/etc' | ||
+ | |||
+ | If you want to use a calibrated touchscreen with your Qt application you need to specify where Tslib files are: | ||
+ | <code> | ||
+ | export QWS_MOUSE_PROTO=tslib:/dev/input/event0 | ||
+ | export TSLIB_CALIBFILE=/usr/local/etc/pointercal | ||
+ | export TSLIB_CONFFILE=/usr/local/etc/ts.conf | ||
+ | export TSLIB_PLUGINDIR=/usr/local/lib/ts | ||
+ | </code> | ||
