qt-embedded2.3.10移植记录

Tslib移植：

export TSLIB_TSEVENTTYPE=event0

export TSLIB_FBDEVICE=/dev/fb0   //可以不要

export TSLIB_TSDEVICE=/dev/input/event0

export TSLIB_CONFFILE=/mnt/nfs/etc/ts.conf

export TSLIB_CONSOLEDEVICE=none

export TSLIB_CALIBFILE=/tmp/pointercal

export TSLIB_PLUGINDIR=/mnt/nfs/share/ts/plugins

export LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/mnt/nfs/lib

 

ts_read_raw.c函数中要定义：

#define USE_INPUT_API 1

选择

#ifdef USE_INPUT_API

       struct input_event ev;//和驱动里结构一样的

#else

Ucb1x00触摸屏驱动通过event0时间来控制的。

 

触摸屏分辨率默认640x480，修改成400x480可以完成校准。

屏大小为800x480

 

./autogen.sh

./configure CC=arm-linux-gcc --prefix=/root/tslib --host=arm-linux

修改/tslib/plugins/Makefile里面找rpath

将LDFLAGS :=$(LDFLAGS) -rpath $(PLUGIN_DIR)

修改为：

LDFLAGS :=$(LDFLAGS) -rpath `cd $(PLUGIN_DIR) && pwd`（这个可是顿号）

make

make install

 

qt-x11-2.3.2移植

修改一个头文件错误：

qvalue…….h  中：

加入：this->

 

qt-embedded2.3.10移植

[root@~qte_arm]#cp -a src/.libs/*  /qte_arm/qte-2.3.7/lib/

[root@~qte_arm]#cp -a plugins/.libs/*.so  /qte_arm/qte-2.3.7/lib/

[root@~qte_arm]#cp -f src/*.h  /qte_arm/qte-2.3.7/include/

Copy tslib中的一些lib和include到qte-2.3.7中

修改qte-2.3.7交叉编译环境参数文件使其增加对触摸屏的支持；

       用vi编辑/qte_arm/qte-2.3.7/configs/linux-arm-g++-shared文件,将SYSCONF_LIBS    = -lm 修改为SYSCONF_LIBS = -lm －lts，然后保存修改后的文件。在编译qte-2.3.7源代码过程中使用触摸屏共享库。

 

会提示错误

undefined reference to `operator new[](unsigned int)'

之类的错误提示

就是改一下对应的Makefile里的arm-linux-gcc 为arm-linux-g++

或者make sub-src，不编译例子

 

 

编译QT应用程序

1、QTdesiger生成ledtest.ui工程文件

2、

$QTDIR/bin/uic -o ledtest.h ledtest.ui

$QTDIR/bin/uic -o ledtest.cpp -impl ledtest.h ledtest.ui

3、vi main.cpp

4、progen –t app.t –o ledtest.pro

注意：修改ledtest.pro文件，把INTERFACES= ledtest.uic 修改为：INTERFACES=

否则提示：

5、export TMAKEPATH=/tmake 的安装路径（如$TMAKEDIR）/lib/qws/linux-arm-g++

6、tmake –o makefile ledtest.pro

注意：LIBS    =       $(SUBLIBS) -L/root/arm_qt/qt-2.3.10/lib -lm -lqte –lts

加入-lts表示动态连接tslib库，支持触摸屏。

7、make
