Qtopia2 编译

使用LTIB编译Qtopia2

在Qtopia 2中使用鼠标

编译Qtopia的时候配置了使用鼠标的选项：

[*] Use usb mouse instead of touchscreen in qtopia by default

同时内核使能了USB HID等，已经插入了USB光学鼠标，在内核中已经看到了鼠标：

[root@nxp root]# ls /dev/input/by-id/usb-15ca_USB_Optical_Mouse-event-mouse -la

lrwxrwxrwx 1 root root 9 Jan 1 00:18 /dev/input/by-id/usb-15ca_USB_Optical_Mouse-event-mouse -> ../event1

另外，使用cat命令读取/dev/input/event1，触动鼠标，能够看到有信息。

但是，在Qtopia 2下就是无法使用。进入Qtopia 欢迎界面，看不到鼠标，点击鼠标，屏幕没有任何反应。

问题

#!/bin/sh

export QTDIR=/opt/Qtopia

export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

export QPEDIR=/opt/Qtopia

export HOME=/root

export PATH=$QPEDIR/bin:$PATH

# export QWS_MOUSE_PROTO="USB:/dev/mouse0"

export QWS_MOUSE_PROTO="USB:/dev/input/event1"

export QWS_KEYBOARD="USB:/dev/event0"

export QWS_SIZE="320x240"

/opt/Qtopia/bin/qpe& >/dev/null 2>/dev/null

出现这样的警告，鼠标无法正常使用：

Warning: QServerSocket: failed to bind or listen to the socket

Warning: Failed to bind to port 4243

Warning: QServerSocket: failed to bind or listen to the socket

Warning: Failed to bind to port 4242

Warning: QServerSocket: failed to bind or listen to the socket

Warning: Failed to bind to port 4243

NXP 支持回复：

export QWS_MOUSE_PROTO="USB:/dev/input/mouse1"

U鼠可以工作，能正常运行Qtopia。你试试看。

触摸屏的在看。

在Qtopia 2中使用触摸屏

在编译Qtopia2的时候已经配置了数用触摸屏的选项：

[*] Use touchscreen

Linux系统启动后，也能够看到触摸屏的设备节点：

[root@nxp root]# ls /dev/input/by-path/platform-lpc32xx-ts-event- -la

lrwxrwxrwx 1 root root 9 Jan 1 00:35 /dev/input/by-path/platform-lpc32xx-ts-event- -> ../event0

同样，使用cat命令读取/dev/input/event0设备，点击触摸屏，也有数据显示。

但是，在Qtopia 2下还是无法使用触摸屏。进到Qtopia欢迎界面，点击屏幕没有任何反应。

问题解决

1：升级drivers/input/touchscreen/lpc32xx_ts.c文件；

2：修改dist/lfs-5.1/qtopia/qtopia.spec文件，在platform in中增加：

88 phy3250)

89 if [ -n "$PKG_QTOPIA_WANT_TSLIB" ]

90 then

91 export EXTRA_QTE_CONFIG="-tslib"

92 fi

93 # export QPE_EXTRA_CFG="-tslib"

94 ;;

3：修改/etc/rc.d/init.d/qtopia脚本，在其中增加/dev/input/event0 到 /dev/touchscreen/ucb1x00的软链接； //不添加链接，Qtopia的触摸屏可用，但ts_*系列函数无法使用。

mkdir /dev/touchscreen

ln -s /dev/input/event0 /dev/touchscreen/ucb1x00

4：设置触摸屏：

export TSLIB_TSDEVICE=/dev/input/event0

export TSLIB_PLUGINDIR=/usr/lib/ts

export TSLIB_CONFFILE=/usr/etc/ts.conf

export QWS_MOUSE_PROTO="TPanel:/dev/input/event0"

如果不设置到ucb1x00的软链接，手工输入export TSLIB_TSDEVICE=/dev/input/event0后，ts_*程序可用，但是在qtopia脚本中指定却不管用，奇怪了。

主机编译Qtopia2

单独编译Qtopia2，同样需要依赖于几个库：e2fsprogs jpeg-6b zlib libpng等。

需要首先交叉编译这些库，可以考虑添加到交叉编译器中，当然也可以指定链接路径。

编译e2fsprogs-1.41.4

需要先确认主机有没有e2fsprogs，如果没有再进行安装：

./configure

make

sudo make install

编译jpeg-6b

./configure --enable-shared

vi Makefile

prefix = /opt/nxp/gcc-4.3.2-glibc-2.7/arm-vfp-linux-gnu/

CC= arm-vfp-linux-gnu-gcc AR= arm-vfp-linux-gnu-ar rc AR2=arm-vfp-linux-gnu-ranlib

make

sudo make install

如果出现/opt/nxp/gcc-4.3.2-glibc-2.7/arm-vfp-linux-gnu//man/man1/cjpeg.1无法访问的错误，是因为系统没有/opt/nxp/gcc-4.3.2-glibc-2.7/arm-vfp-linux-gnu//man/man1目录，使用

sudo madir -p /opt/nxp/gcc-4.3.2-glibc-2.7/arm-vfp-linux-gnu//man/man1/创建后再次安装即可。

编译zlib

./configure --shared

vi Makefile
