在Delphi中编译工程的时候，经常会出现像 File not found ExceptionLog.dcu 的状况。

一、将ExceptionLog去掉或注释掉，再进行编译。

二、若第一种不行，则是Delphi的环境配置问题，也是该工程配置问题。解决办法：

在Project Manager中右击该工程，选择options,在弹出的对话框中选择Directories/Conditionals.在右边进行相应的设置，这里主要是设置，单元文件编译后生成的DCU文件所存放的位置。主要设置两项，一是Unit output directory将其浏览到你所要放置的目录中，然后下面的Search path与上面设置的路径一致。这样在编译的时候，Delphi环境就可以找到编译后的文件了。-In Delphi compiler works, it often appears as File not found　ExceptionLog.dcu　situation.

First, the ExceptionLog remove or comment, and then compile.

Second, if the first one does not work, it is a configuration problem Delphi environment, but also the project configuration problems. The solution:

Right-click on the project in the Project Manager,　the options, in the dialog box,　the Directories/Conditionals. The right of the appropriate settings, here is mainly set up after the unit file compiler generated DCU file storage location. Two main settings, one Unit output directory to browse to the directory where you want to place, and then the following path Search path consistent with the above settings. So at compile time, Delphi environment you can find the file compiled.
