.pro 文件的问题
--------------------编程问答-------------------- 定义变量$$获取变量的指 --------------------编程问答--------------------
怎么定义变量? 这上面的没有的都要挨个定义? --------------------编程问答-------------------- qmake自带一些变量。除此之外的,就是用户定义的变量。 --------------------编程问答-------------------- target=lib
就行了,你上面的指定错了。呵呵,小伙子给分吧。 --------------------编程问答-------------------- $$+变量,代表的是取前面你定义的变量值。 --------------------编程问答-------------------- include(../qxmpp.pri)
你包含了这个东西,.pro文件中用的一些变量可以统一在这里面定义。然后在.pro文件里面$$+变量名就是取值的意思,比如说你在.pri中声明LOCAL_PATH=$$PWD,然后在.pro文件中使用$$LOCAL_PATH代表的是当前路径。 --------------------编程问答--------------------
qmake 自带的变量,能举个简单的例子吗,用户定义的变量 指的是什么? 环境变量? 还是在pro文件中定义的? --------------------编程问答--------------------

这个是比特币Qt源码自带的pro。定义变量的好处是修改方便。另外可以通过命令行传进去。针对于多处使用有意义。如果使用的地方较少。可以直接替换。
