曾经做的一个电气防火的项目

来源：互联网发布：华硕最优化设置编辑：程序博客网时间：2024/04/30 01:03

开发环境:

宿主机主机编译环境 winxp qdeveloper0.24 + gdb +MinGW

交叉编译环境 arm-linux-gcc-3.4.1
操作系统     redhat linux 9.0c
   触摸屏 tslib-1.4 (可选 )
   qte 环境 Qtopia coe 4.3.0

一.搭建开发环境

///////////////////////////////////////////////////////////////////
//
// 开启ftp,telnet服务 --root用户
//
///////////////////////////////////////////////////////////////////
关闭防火墙,关闭SELINUX
开启telent,Telnet root用户的登入
# mv /etc/securetty /etc/securetty.bak

///////////////////////////////////////////////////////////////////
//
// 开发主机安装ftp client端,及netterm工具
//
///////////////////////////////////////////////////////////////////

///////////////////////////////////////////////////////////////////
//
// 安装ELDK（Embedded Linux Development Tools）--root用户
//
///////////////////////////////////////////////////////////////////

1、挂载光驱
#mount -t iso9660 /dev/cdrom /mnt/cdrom
注：自动挂载可能权限不足，最好手动挂载。
2、更改光驱权限，增加执行权限
#chmod a+x /mnt/cdrom
3、进入光驱目录，安装
#cd /mnt/cdrom
#./install -d /opt/eldk arm
4.设置环境变量
#vi /etc/profile 中加入下面内容
CROSS_COMPILE=arm-linux-
PATH=$PATH:/opt/eldk/usr/bin:/opt/eldk/bin
#export CROSS_COMPILE PATH
保存。然后执行
#source profile
5. 设定 NFS 的挂载能力
#cd /opt/eldk/arm/dev
#sudo /mnt/cdrom/ELDK_MAKEDEV

#cd /opt/eldk/arm/eldk
#sudo /mnt/cdrom/ELDK_FIXOWNER -a arm

注意:linux内核文件 /opt/eldk/arm/usr/src/linux/

[additional platform specific options (see below)]

Installation options:

These are optional, but you may specify install directories.

-prefix <dir> ...... This will install everything relative to <dir>
(default /usr/local/Trolltech/Qt-4.3.0)

* -prefix-install .... Force a sandboxed "local" installation of
                         Qt. This will install into
                         /usr/local/Trolltech/Qt-4.3.0, if this option is
                         disabled then some platforms will attempt a
                         "system" install by placing default values to
                         be placed in a system location other than
                         PREFIX.

You may use these to separate different parts of the install:

    -bindir <dir> ......... Executables will be installed to <dir>
                            (default PREFIX/bin)
    -libdir <dir> ......... Libraries will be installed to <dir>
                            (default PREFIX/lib)
    -docdir <dir> ......... Documentation will be installed to <dir>
                            (default PREFIX/doc)
    -headerdir <dir> ...... Headers will be installed to <dir>
                            (default PREFIX/include)
    -plugindir <dir> ...... Plugins will be installed to <dir>
                            (default PREFIX/plugins)
    -datadir <dir> ........ Data used by Qt programs will be installed to <dir>
                            (default PREFIX)
    -translationdir <dir>.. Translations of Qt programs will be installed to <dir>
                            (default PREFIX/translations)
    -sysconfdir <dir> ..... Settings used by Qt programs will be looked for in <dir>
                            (default PREFIX/etc/settings)
    -examplesdir <dir> .... Examples will be installed to <dir>
                            (default PREFIX/examples)
    -demosdir <dir> ....... Demos will be installed to <dir>
                            (default PREFIX/demos)

You may use these options to turn on strict plugin loading.

    -buildkey <key> .... Build the Qt library and plugins using the specified
                         <key>. When the library loads plugins, it will only
                         load those that have a matching key.

Configure options:

The defaults (*) are usually acceptable. A plus (+) denotes a default value
that needs to be evaluated. If the evaluation succeeds, the feature is
included. Here is a short explanation of each option:

# ./configure -no-openssl //redhat9下make时ssl出错
# gmake
# gmake install 默认目标路径（/usr/local/Trolltech/Qt-4.3.0/）

gmake confclean 清除配置
./configure 上加上 ——release 参数。这样只编译一份release的，可以省下一半以上的时间。

可选

PATH=/usr/lib/qt4/bin：$PATH export PATH QTDIR=/usr/lib/qt4/ export QTDIR
执行以下命令：

    ln -s /usr/lib/qt4/bin/designer designer4
    ln -s /usr/lib/qt4/bin/assistant assistant4
    当然，以后如果使用了KDE4桌面就不会有这等麻烦事。

#vi /etc/profile
添加 export PATH=/usr/local/Trolltech/Qt-4.2.3/bin:$PATH

#source /etc/profile

装完qt-x11后还得编译tools、qvfb。
//////////////////////////////////////////////////////////////////
//
// 安装编译tools & qvfb
//
//////////////////////////////////////////////////////////////////

# cd tools //qvfb不包含在tools里
# make
# make install

# cd tools/qvfb
# make
# make install

装完qt-x11后还得编译qvfb。
cd qt/tools/qvfb后，make就能生成qvfb工具。所生成的qvfb工具不在当前目录，而失去了QTDIR，所以今后用的时候要将其拷贝到 QTEDIR中

问题一：执行qvfb时报“Qtopia Core data directory is not owned by user 0”的问题处理
目录的所有者改为普通用户，且将权限改为777也不起作用，不明白“Qtopia Core data directory”是什么意思。造成QTOPIA要用ROOT权限编译的假象。

处理方法:
是/tmp下生成的东西，你rm /tmp/qt* /tmp/.qt* -r

<可能出现的错误一>
为了防止出现“libtool: link: only absolute run-paths are allowed“的错误，在/tslib/plugins/Makefile里面找rpath，找到将其注释并加上绝对路径。
#LDFLAGS := $(LDFLAGS) -rpath $(PLUGIN_DIR)
LDFLAGS := $(LDFLAGS) -rpath `cd $(PLUGIN_DIR) && pwd`

# make
# make install

排除错误
1.ts_calibrate时总是出现一个错误：ts_open:Inappropriate ioctol for device. 可能是自己板子的触摸屏驱动不支持ioctl操作
./configure 时,添加 --enable-inputapi=no
