我没有得到使用SCons更新项目的自动构建版本。首先，我在源文件中更改了一些内容，scons告诉我：如何在源文件更改时更新scons版本
scons: done reading SConscript files.
scons: Building targets ...
scons: `.' is up to date.
scons: done building targets.
如何更新自动构建？

有没有办法告诉SCons有关所有源代码和配置文件？我猜，它没有看到哪些文件被改变。另一种方法是每次运行EiffelStudio编译器，它足够聪明，可以在工作台模式下进行增量重新编译，但可能不适合构建最终化的应用程序。 –
是的，这是解决方案：EiffelStudio编译器'ec'检测到变化！ – Leder
好。我添加了一个答案，以便您可以将问题标记为已解决。 –
