交叉编译qt4.8.4 for ARM

我的安装环境：

ubuntu12.04,

QT Library： 4.8.1 qt-everywhere-opensource-src-4.8.1.tar.gz

QT Creator：2.4.1 qt-creator-linux-x86-opensource-2.4.1.bin

1. 执行命令：

./configure -prefix /usr/local/qt-4.8.1-for-arm -embedded arm -host-little-endian -no-cups -no-3dnow -nomake examples -nomake demos -nomake docs -xplatform /qws/linux-arm-g++

输出：

.......

The target system byte order could not be detected!

Turn on verbose messaging (-v) to see the final report.

You can use the -little-endian or -big-endian switch to

./configure to continue.

解决办法：加入-little-endian

./configure -prefix /usr/local/qt-4.8.1-for-arm -embedded arm -host-little-endian -little-endian -no-cups -no-3dnow -nomake examples -nomake demos -nomake docs -xplatform /qws/linux-arm-g++

输出：

......

Qt is now configured for building ,just run 'make'

Once everything is built , you must run 'make install'

Qt will be installed into /usr/local/qt-4.8.1-for-arm

To reconfigure ,run 'make confclean' and 'configure'

2. 输入make, 得到下面的错误：

make[1]: arm-linux-g++：命令未找到

make[1]: *** [.obj/release-shared-emb-arm/qabstractanimation.o] 错误 127

make[1]:正在离开目录 `/home/tangys/qt-everywhere-opensource-src-4.8.1/src/corelib'

make: *** [sub-corelib-make_default-ordered] 错误 2

解决办法：-xplatform /qws/linux-arm-g++ 改为 -xplatform /qws/linux-arm-gnueabi-g++

先执行: make confclean ，

然后执行：

./configure -prefix /usr/local/qt-4.8.1-for-arm -embedded arm -host-little-endian-little-endian -no-cups -no-3dnow -nomake examples -nomake demos -nomake docs -xplatform /qws/linux-arm-gnueabi-g++

输出：

Qt is now configured for building ,just run 'make'

Once everything is built , you must run 'make install'

Qt will be installed into /usr/local/qt-4.8.1-for-arm

To reconfigure ,run 'make confclean' and 'configure'

3. 执行make

4. 执行make install （需要 sudo make install）

5. 修改环境变量，在~/.bashrc中添加以下语句

export ARMQTDIR=/usr/local/qt-4.8.1-for-arm
export PATH=$ARMQTDIR/bin:$PATH
export LD_LIBRARY_PATH=$ARMQTDIR/lib
export QMAKESPEC=/usr/local/qt-4.8.1-for-arm/mkspecs/qws/linux-arm-gnueabi-g++

　　重新加载~/.bashrc：

source ~/.bashrc

　

　检查是否成功：

qmake -v

QMake version 2.01a

Using Qt version 4.8.1 in /usr/local/qt-4.8.1-for-arm/lib

which qmake

/usr/local/qt-4.8.1-for-arm/bin/qmake
