桌面版qmake和交叉编译版qmake的切换_qmake arm

一、交叉编译版QT安装路径：/usr/local/qt-4.8.1-for-arm

1.  将/usr/local/qt-4.8.1-for-arm/bin/ 路径下的qmake 改名为armqmake

2. 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++

3. 使环境变量生效，执行source ~/.bashrc

4. 验证armqmake生效：

tangys@tysPC:~$ armqmake -v
QMake version 2.01a
Using Qt version 4.8.1 in /usr/local/qt-4.8.1-for-arm/lib

二、桌面版QT安装路径：/usr/local/Trolltech/Qt-4.8.4/

1. /usr/local/Trolltech/Qt-4.8.4/bin 路径下的qmake不改名，就用qmake

2. 修改环境变量，在~/.bashrc中添加以下语句

export QTDIR=/usr/local/Trolltech/Qt-4.8.4 
export PATH=$QTDIR/bin:$PATH  
export MANPATH=$QTDIR/man:$MANPATH  
export LD_LIBRARY_PATH=$QTDIR/lib:$LD_LIBRARY_PATH

3. 使环境变量生效，执行source ~/.bashrc

4. 验证qmake安装正确：

tangys@tysPC:~$ qmake -v
QMake version 2.01a
Using Qt version 4.8.4 in /usr/local/Trolltech/Qt-4.8.4/lib
