qmake：如何通过命令行提供多个变量？

发布于 2024-08-28 11:37:54 字数 322 浏览 7 评论 0原文

qmake 允许通过命令行界面提供变量，如下所示：

qmake "CONFIG += release" "MY_VAR = hello"

因此我可以在 .pro 文件中使用 $$MY_VAR 。但是否有可能以这种方式提供多个变量呢？我已经尝试过

qmake "CONFIG += release" "MY_VAR = hello" "MY_ANOTHER_VAR = hi"

但它不起作用（引发错误）。有什么提示吗？

原文

qmake allows to supply a variables via a command-line interface like this:

qmake "CONFIG += release" "MY_VAR = hello"

So i can use $$MY_VAR inside a .pro file. But is it possible to suply more than one variable such way? I have tried

qmake "CONFIG += release" "MY_VAR = hello" "MY_ANOTHER_VAR = hi"

But it did not work (raises error). Any hints?

这个问题具有误导性。您可以提供任意数量的变量。

.pro 文件：

....
message($VAR1)
message($VAR2)

qmake 运行：

qmake ... "VAR1=VALUE1" "VAR2=VALUE2"

编译器输出：


09:40:13: Running build steps for project test...
09:40:13: Starting: "c:\qtsdk\desktop\qt\4.8.1\mingw\bin\qmake.exe" D:\tmp\test\test.pro -r -spec win32-g++ "CONFIG+=declarative_debug" "VAR1=VALUE1" "VAR2=VALUE2"
Project MESSAGE: VALUE1
Project MESSAGE: VALUE2
Project MESSAGE: VALUE1
Project MESSAGE: VALUE2
Project MESSAGE: VALUE1
Project MESSAGE: VALUE2
09:40:14: The process "c:\qtsdk\desktop\qt\4.8.1\mingw\bin\qmake.exe" exited normally.

The question is misleading. You CAN supply any number of variables.

.pro file:

....
message($VAR1)
message($VAR2)

qmake run:

qmake ... "VAR1=VALUE1" "VAR2=VALUE2"

compiler output:


09:40:13: Running build steps for project test...
09:40:13: Starting: "c:\qtsdk\desktop\qt\4.8.1\mingw\bin\qmake.exe" D:\tmp\test\test.pro -r -spec win32-g++ "CONFIG+=declarative_debug" "VAR1=VALUE1" "VAR2=VALUE2"
Project MESSAGE: VALUE1
Project MESSAGE: VALUE2
Project MESSAGE: VALUE1
Project MESSAGE: VALUE2
Project MESSAGE: VALUE1
Project MESSAGE: VALUE2
09:40:14: The process "c:\qtsdk\desktop\qt\4.8.1\mingw\bin\qmake.exe" exited normally.
