QT 交叉 编译问题整理( ing )

解压缩

tar -vxf qt-everywhere-src-5.12.4.tar.xz
cd qt-everywhere-src-5.12.4

修改 qmake 版本

/etc/profile

/Qt5.12.4/5.12.4/gcc_64/bin:$PATH

// 创建文件 设置权限

touch autoConfigure.sh
chmod 777 autoConfigure.sh

// 编辑文件

gedit autoConfigure.sh

// 加入内容
-prefix是安装目录；
-xplatform是arm编译器类型，在qtbase/mkspecs目录下，根据自己交叉编译工具进行相应的替换

配置 指令 备用

1. ./configure -prefix ~/Qt5.12.4 -confirm-license -opensource -static -release -xplatform linux-arm-gnueabi-g++ -qt-libjpeg -no-xcb
   -no-largefile -no-accessibility -no-sse2 -nomake tests -nomake examples -nomake tools -no-openssl -no-nis -no-cups -no-dbus -no-sql-sqlite -skip qt3d -skip qtactiveqt -sk ip qtandroidextras -skip qtcanvas3d -skip qtcharts
   -skip qtconnectivity -skip qtdatavis3d -skip qtdeclarative -skip qtdo c -skip qtgamepad

./configure
-prefix ~/Qt5.12.4 \

错误统计

/home/hello/qt-everywhere-opensource-src-5.4.0/qtbase/src'
make[1]: *** [sub-src-make_first] 错误 2
make[1]:正在离开目录
/home/hello/qt-everywhere-opensource-src-5.4.0/qtbase'
make: *** [module-qtbase-make_first] 错误 2

主要原因是它依赖的dbus目录没有编译，解决方法如下：
#cd /home/hello/qt-everywhere-opensource-src-5.4.0/qtbase/src/dbus执行下面的
如没有Makefile,执行下面的命令
#../../bin/qmake dbus.pro
然后执行Make.
#make
编译成功后，再切换到/home/hello/qt-everywhere-opensource-src-5.4.0目录下，执行
#make
