如何让qmake生成的Makefie不链接Qt库

如何让qmake生成的Makefie不链接Qt库
在CSDN上搜索了一下，大部分关于qmake的实例都是链接到Qt库，包括QtCore和Q tGui。

如果只是想写一个普通的C++命令行程序，链接Qt库显然是使得最终生成的程序尺寸变得臃肿，而且必须要安装庞大的Qt包。

那么如何让qmake不链接到Qt库呢？
默认情况下，qmake是要链接QtCore和QtGui两个库的。

即使你什么也不做，因为这是默认行为。

通过以下配置可以解除这种配置。

1.#qmake 命令行
2.#qmake -makefile -spec linux-g++ TcpServer.pro TARGET = TcpServe
r.bin TEMPLATE = app
3.#不需要QT
4.CONFIG -= qt
5.#编译debug模式
6.CONFIG += debug
7.#指定中间文件目录
下面一栏是qmake默认配置下生成的Makefile。

可以清晰的看出，默认生成的Makefile 增加了Qt宏定义、头文件路径、QtGui和QtCore链接库。

而上面一栏是增加了”CON FIG –= qt “配置的生成的Makefile，显然清爽了很多。

只有我们指定的库文件。

顺带提一下，qmake中访问环境变量的方法是$$(env_var)，env_var是变量名。

注意是两个美元符加小括号包围哦^_^
qmake生成的makefile尺寸还是很精简的，可以清晰看懂。

我把上面完整的Makefile 贴出来。
