Hi all,

I'm trying to create a package to that contains a unit which defines a TShape descendant component following this example:

http://wiki.lazarus.freepascal.org/Lazarus_Packages#Adding_existing_components_to_a_Package

The problem that I'm having is that package overwrites the .pas file that I include with:

{ This file was automatically created by Lazarus. Do not edit! This source is only used to compile and install the package. }

unit pos_button;
interface
uses
   pos_button, LazarusPackageIntf;
implementation
procedure Register;
begin
   RegisterUnit( 'pos_button', at pos_button.Register) ;
end;
initialization
   RegisterPackage( 'pos_button', at Register) ;
end.

Before trying to save/compile the package this source file contains the source for the component. After save/compile the contents are replaced with the above source.

Try renaming (saving) your package to TPos_button.

Thanks, that got me a bit further, but now when I try to compile the package I get error saying that Graphics unit cannot be found located in my component's .pas file. Yet, if I compile the unit without the package, it compile fine (For instance, if I add it to an existing package).

Never mind, I thought LCL was implicitly added as a requirement.

Thanks,

You named the package the same as the unit.
The IDE should not allow this. Please create a bug report and explain how you did that. Did you create a new package, added the file and then saved the package?

Actually, I have yet to get my password from the bug tracker and I have been lazy in not creating a new profile which I'll do after writing this email :)

The unit source name is:

pos_button.pas

I named the .lpk file:

posbutton.lpk

I figured that the names should not be exact, but I suppose that the IDE somehow stripped the underscore ?

At any rate,

1. I created the source file first.

2. Create the packages and added through "Add Unit" tab.

3. Saved the lpk file as posbutton.lpk

4. Compiled it and that is when it overwrote my source file.

Here it works. That means, it does not strip the underscore. The only place where underscores are stripped are in the widgetsets for labels. I don't see any relationship.
Can you reproduce it?

I added a check in svn 15029 to forbid naming a package as a unit.

Mattias,

Is this included in snapshots? I have problems when trying to build from sources on Windows, but I'll download the latest snapshot this weekend and give it a go again and see if I can get it to replicate the problem or not.

Thanks a bunch for your help.

Any news?

Snapshots are built daily.

Mattias

It seems that page that hosts the snapshots
(http://www.hu.freepascal.org/lazarus/) is down right now, at least from where I am. I'll try to grab the latest later today/tonight and try.

Thanks,

Well the IDE allows it AFAIK. I encountered this bug a long time ago by creating a new package with a unit, and saving the package (Save or Save As??) with the same name as that of the unit. Hadn't I had a backup, I would have lost the unit altogether as the IDE happily replaced my unit without warning. The bug tracker was down then, and I forgot later on about the issue.

Downloading now. Thanks Damien.

I downloaded latest snapshot, Mattias. I was unable to get replicate the problem with using the underscore and it create the package as was expected.

However, I then tried to create a package with the same name as the unit that contained the component, "pos_button.pas" and "pos_button.lpk". Saved, the package, added "pos_button.pas" to the package. Saved, compiled and it did overwrite the "pos_button.pas" file.

I have downloaded and tried this with:
Lazarus-0.9.25-fpc-2.2.1-20080501-win32.exe

No need for the bug report. I already added a check to the IDE.

Mattias

Good.

It is not yet in the current snapshot. It will be in the next. Snapshots are only built daily.

Mattias

Ah, time difference misunderstanding here. I'll try it again with (my) tomorrow's snapshot. ;)
