arm-linux-gcc:4.5.1
1.下载Qt源码并解压
我下载的为:qt-everywhere-opensource-src-4.7.2.tar.gz
mkdir /root/build_qt
cd /root/build_qt
tar zxvf qt-everywhere-opensource-src-4.7.2.tar.gz
mv qt-everywhere-opensource-src-4.7.2 qte
cd qte
2.设置安装环境变量,编写install.sh
vim install.sh
export PATH=/usr/local/arm/4.5.1/bin:$PATH export CPLUS_INCLUDE_PATH=/usr/local/arm/4.5.1/arm-none-linux-gnueabi/include/c /4.5.1:/usr/local/arm/4.5.1/arm-none-linux-gnueabi/include/c /4.5.1/arm-none-linux-gnueabi/:/usr/local/arm/4.5.1/arm-none-eabi/include/c /4.5.1:/usr/local/arm/4.5.1/arm-none-eabi/include/c /4.5.1/arm-none-eabi:$CPLUS_INCLUDE_PATH
source install.sh
3.修改QTE源码目录中的src/gui/embedded/qmouselinuxtp_qws.cpp文件,添加触摸屏支持
vim src/gui/embedded/qmouselinuxtp_qws.cpp
QString mousedev;
if (device.isEmpty()) {
mousedev =QLatin1String("/dev/event0");
/*
#ifdefined(QT_QWS_IPAQ)
# ifdefQT_QWS_IPAQ_RAW
mousedev =QLatin1String("/dev/h3600_tsraw");
# else
mousedev =QLatin1String("/dev/h3600_ts");
# endif
#else
mousedev =QLatin1String("/dev/ts");
#endif
*/
4.需要安装tslib的需要先将tslib库解压好,我的不需要,故不要了,跳过
5.配置编译QTE
vim arm_build.sh
echo yes | ./configure -opensource -embedded arm -xplatform qws/linux-arm-g -webkit -qt-libtiff -qt-libmng -qt-mouse-pc -no-mouse-linuxtp -no-neon -depths 4,8,16,32 -qvfb 2>&1 | tee ./qteconfig.log
source arm_build.sh
便开始进行配置了,其中我删除了有关tslib选项,有需要的要加上
接着会出错:
/root/built_qt/qte/src/corelib/tools/qlocale.cpp: In function ‘char* qdtoa(double, int, int, int*, int*, char**, char**)’: /root/built_qt/qte/src/corelib/tools/qlocale.cpp:6639: 错误:‘fenv_t’ 在此作用域中尚未声明 /root/built_qt/qte/src/corelib/tools/qlocale.cpp:6639: 错误:expected `;' before ‘envp’ /root/built_qt/qte/src/corelib/tools/qlocale.cpp:6640: 错误:‘envp’ 在此作用域中尚未声明 /root/built_qt/qte/src/corelib/tools/qlocale.cpp:6640: 错误:‘feholdexcept’ 在此作用域中尚未声明 /root/built_qt/qte/src/corelib/tools/qlocale.cpp:6655: 错误:‘fesetenv’ 在此作用域中尚未声明
目前解决方法:把/usr/include中的fenv.h 复制到qlocale.cpp所在目录 并修改#include <fenv.h>为#include "fenv.h" cp /usr/include/fenv.h /root/build_qt/qte/src/corelib/tools/ #vim /root/build_qt/qte/src/corelib/tools/qlocale.cpp 81 将#include <fenv.h>改成#include "fenv.h" 再source arm_build.sh
没有出错,继续下一步
6.make&& make install 2>&1 | tee ./qtemake.log
便是长时间的编译了......等待
还以为中间会有出错的,但是很给力,一直到结束都没错。好了,一切就绪,接下来就开始做界面了!
