Overview
This page is about one of the most prominent errors of pascal: unit not found. This error has a lot of reasons and this page tries to gather most of the reasons, how to find out, which problem it is, and how to solve it.
Step 1: Compiler or IDE
Although the compiler and the IDE are using quite similar search algorithms to find a unit, there are some differences.
Common:
- Both search units in the search path.
- Both search first for pascal sources (.pas, .pp) files. Under MacPAS mode: search for .p files too.
- Both search for several cases: normal case, lower case, upper case. For example: if the uses section contains 'Unit1', then it searches:
1. Unit1.pp 2. unit1.pp 3. UNIT1.PP 4. Unit1.pas 5. unit1.pas 6. UNIT1.PAS
They are searched in every directory of the search path.
