Using another unit

[B4R]

Created a new project.
Added another unit to the project and defined a class Utility in it. Saved the unit as 'utility.pas'.

Now, I want to use that unit in the 'unit1.pas' unit. So, I add its name to the 'uses' section under 'interface'.

This does not build: Error: Cannot find utility used by Unit1 of the Project Inspector.
Tried to add 'uses' section to 'implementation': no dice.
Tried to use 'Utility in 'utility.pas'', capitalized, all lowercase: no dice.

I know that my Delphi is rusty and I ran out of ideas.
I looked at examples, for instance at C:\lazarus\examples\dropfiles\unit2.pas and found that it simply does that which fails in my project: uses Unit1;
What am I doing wrong?

hello B4R,
not clear what you mean:

Added another unit to the project and defined a class Utility in it. Saved the unit as 'utility.pas'.

does it mean that you have a file named utility.pas with internally declared

Code: Pascal  [Select][+][-]

1. Utility = class
2. end;
3.  

this combination does not compile. (Duplicate identifier)

However, If you added utility to uses and the compiler said:

Error: Cannot find utility used by Unit1 of the Project Inspector.

then your utility.pas is not in the search path of projects. where is utility.pas ?
(I suggest also to change the name of such unit in something more unique)

Simply keeping conventions would solve this:

Code: Pascal  [Select][+][-]

1. TUtility = class
2. end;

The convention for all user types is a T as prefix, although the language does not enforce it. And then the class name and the unit name do not clash anymore.

It's like this:

You have a typo in your unit name (see your screenshot)
utility <> uitlity

But you wrote wrong file name!!!!

[Thaddy]

With units it is also important that the file name on disk matches the unit name exactly, except for the pas or pp extension.

Bingo!
Thank you, sir!
