Inno Setup IDE和ISCC / ISPP传递定义 [英] Inno Setup IDE and ISCC/ISPP passing define

问题描述

我想同时使用InnoIDE和ISCC / ISPP，不同之处在于我想传递一个参数，该参数将覆盖脚本中的#define。

I would like to use both the InnoIDE and ISCC/ISPP, the difference being that I would like to pass in a parameter, which will override a #define in the script.

在命令行中，我可以传递/ Dmyarg = myvalue。与脚本中的 #define myarg myvalue相同。

In the command line I can pass /Dmyarg=myvalue. That is the same as "#define myarg myvalue" in the script.

遗憾的是，脚本的优先级高于命令行值。我知道，就像我尝试过的那样。我显然可以注释掉脚本中的#define，并且命令行定义可以使用，但是然后我将无法使用IDE进行构建。

Sadly, the script takes precedence over the command line value. I know, as I tried. I can obviously comment out the #define in the script and the command line define will work, however then I will not be able to use the IDE to build.

是吗可以在InnoIDE中为项目的某个地方设置#define还是有某种方法让命令行#define优先？

Is it possible to set a #define inside InnoIDE somewhere for the project or is there some means to have the command line #define take precedence?

推荐答案

在您的脚本中，执行以下操作：

In your script, do something like this:

#ifndef myarg
# define myarg "mydefault"
#endif

现在，如果您在IDE中进行编译或使用命令行而不指定/ Dmyarg = something，则它将使用脚本中指定的默认值。否则，如果您确实在命令行上指定了某些内容，则它将使用该内容。

Now, if you compile in the IDE or if you use the command line without specifying /Dmyarg="something", then it will use the default specified in the script. Otherwise, if you do specify something on the command line then it will use that instead.
