tar -xvf zint-2.6.7.tar.gz
cd zint-2.6.7/backend_qt/
若不依赖png,则编辑backend_qt.pro
DEFINES += ZINT_VERSION="\\\"2.6.7\\\""
改成
DEFINES += NO_PNG ZINT_VERSION="\\\"2.6.7\\\""
默认编译的是静态库，若要编译动态库 则编辑backend_qt.pro
CONFIG += staticlib
#CONFIG += dll
改成
#CONFIG += staticlib
CONFIG += dll
生成Makefile
交叉编译，则调用交叉编译出的qt工具
/usr/local/qt5-arm/bin/qmake
若是pc编译，则调用系统工具
qmake
编译
make
静态编译生成libQtZint.a，动态编译生成libQtZint.so.2.6.7 libQtZint.so.2 libQtZint.so.2.6 libQtZint.so把字符串转成条形码并显示在label上
