DCU file not found in Delphi FAQ

DCU cannot be found frequently during Delphi development.

This problem is a headache and people do not know how to solve it. Now I will summarize several problems and solutions.

First: openglox1.dcu cannot be found.

The solution is to add the environment variable to the system and add the binfile path under the Delphi directory.

The second is to use SVN to update and then runProgramError.

Go to the DCU directory to findCodeThe physical path shows this file, but the program cannot be found.

At first, I thought there was a problem with the Code Update, so I went to update it again. As a result, SVN prompts that it was locked. The program cannot run.

After consultation, it turns out that the svn update was interrupted, resulting in a code update problem. Therefore, this error occurs. Now, you only need to clear it in SVN.

Then update the code to run the program.
