QT-embedded-4.5 for x86的安装和使用 [复制链接]

step1. 将qt-embedded-linux-opensource-src-4.5.1.tar.gz拷贝到Linux下，解压缩：

# tar zxvf qt-embedded-linux-opensource-src-4.5.1.tar.gz

# cd qt-embedded-linux-opensource-src-4.5.1

step2. 配置选项并安装,也可以下载安装脚本qte_for_x86.sh：

#./configure \

-release \

-shared \

-no-largefile \

-qt-sql-sqlite \

-plugin-sql-sqlite \

-xmlpatterns \

-exceptions \

-svg \

-webkit \

-qt-zlib \

-qt-gif \

-qt-libtiff \

-qt-libpng \

-no-libmng \

-qt-libjpeg \

-make libs \

-make tools \

-nomake examples \

-nomake docs \

-no-nis \

-no-cups \

-no-iconv \

-no-dbus \

-no-openssl \

-xplatform qws/linux-x86-g++ \

-embedded \

-qt-freetype \

-depths 16 \

-qt-gfx-qvfb \

-no-gfx-transformed \

-no-gfx-multiscreen \

-no-gfx-vnc \

-no-gfx-linuxfb \

-qt-kbd-tty \

-no-kbd-usb \

-qt-kbd-qvfb \

-qt-mouse-pc \

-qt-mouse-qvfb \

-no-glib \

-feature-THREAD \

-feature-CONCURRENT \

-feature-SOUND \

-feature-EFFECTS \

-feature-QWS_MULTIPROCESS \

-silent

#make >log_make 2>&1

#make install >log_install 2>&1

step3. 设置环境变量（两种方法）：

仅当前用户有效（其他用户无效）：修改$HOME/.bash_profile,加入：

PATH=/usr/local/Trolltech/QtEmbedded-4.5.1/bin:$PATH

立即生效：

#source $HOME/.bash_profile

所有用户有效（包括root和普通用户）： 修改/etc/profile,加入以下行（一般在最后一行添加）：

export PATH=/usr/local/Trolltech/ QtEmbedded-4.5.1/bin:$PATH

立即生效：

#source /etc/profile

step4. 在PC机上运行Qt-Embedded程序的方法为： 使用Qt-Embedded for x86的Qt库来编译Qt-Embedded程序，然后使用Qt-x11的qvfb工具仿真调试。下面以demo程序为例,确保qmake来自/usr/local/Trolltech/QtEmbedded-4.5.1/bin：

# qmake -project

# qmake

# make

# qvfb &

# ./demo -qws

我已经按楼上的一步步地做了

在编译 demos 出现了以下错误：


好慢啊，今天花了一个下午把  Qt -embedded 编译好了

在编译demos 时发现错误：

望楼主能看一下，非常感谢！
