1.更改pro文件:(参考:http://blog.csdn.net/derryzhang/article/details/6592229)
CONFIG+=debug_and_release
CONFIG(debug, debug|release){TARGET = ui_debug} else {TARGET = ui_release}
make 或make debug -------生成debug版
make release -------生成release版
make all -------两个版本都生成
2.另一种应用:(参考:http://blog.csdn.net/zqf_office/article/details/23928895)
CONFIG(debug, debug|release) {
LIBS += -L../lib1 -lhellod
} else {
LIBS += -L../lib2 -lhello
}
或
CONFIG(debug, debug|release):LIBS += -L../lib1 -lhellod
CONFIG(release, debug|release):LIBS += -L../lib2 -lhello
3.屏蔽release版本中所有QDebug()提示信息,可以在pro文件中添加DEFINES+=QT_NO_DEBUG_OUTPUT
