如何始终使用Eclipse编译cpp文件？ [英] How to always compile a cpp file with Eclipse?

问题描述

我在我的一个cpp源文件中包含了一个unix时间戳 __ DATE __ ，表示我的程序的生成日期。当然，使用默认设置，它只有当我改变它，但现在我想让它总是编译文件。我试图搜索项目设置，但似乎这将需要更深入的了解编译器。我使用Eclipse和g ++。

I have included a unix timestamp __DATE__ in one of my cpp source files to indicate the build date of my program. Naturally with default setups it compiles the file only when I change it but now I'd like to have it always compiled. I tried to search through the project settings but it seems that this would need deeper understanding of the compiler. I'm using Eclipse with g++.

我试图google并搜索一个答案，但我发现很难找到这个关键字。

I tried to google and search for an answer but I found it difficult to find good keywords for this.

还有一个可标记的差异，我做这个更改头文件而不是源文件？

Also is there a markable difference wether I do this change for a header file instead of the source file?

感谢您的答案。

推荐答案

您可以创建一个预构建步骤，触摸文件（因此时间戳已修改，并强制重新编译该文件）。

You may create a 'pre-build' step which touch the file (so the time stamp is modified and force to recompile the file).
