Summary0017896: Special handling for libraries
DescriptionI'm mass-converting several libraries and I am constantly facing one problem, that shouldn't be there IMHO.

In case of a library an icon is added to the project, which is not needed (e.g. never displayed in any of the platforms I checked).

Can you please explain "In case of a library an icon is added to the project". Which project? You are converting a library, right?

Yes, I'm converting dozens of libraries (*.dll in Windows). Each of these are plugins and thus have only little todo with each other.

I noticed that such libraries are not well supported by Lazarus. In fact these are rather treated as executables (which they are more or less). Thus using the libraries as plugins (with LCL forms) will create a task bar handler containing an icon.

IMO an icon for a library does not make sense nor will does it make sense to show the task bar handler, but that's another story.

Ok, it looks like this is not a converter bug but applies to any such library made with Lazarus. Can you please verify it by creating a new test package (instead of converting an existing package). Then we can classify this issue better.

When do you see the icon on taskbar? Is it always when calling the lib from you program?

I made a test library project and clicked "Run". Lazarus really tried to run it which is a bug for sure. Then:
"Ooops, the debugger entered the error state..."

I also found out once that it is possible to run a library which might indeed be a bug.

In regards of this problem I also created another bug report with the ID 17965, which you might want to check. It also presents a patch to omit the use of icons for a library. In general this needs to be discussed whether libraries do need an icon at all (and on all platforms), but IMHO they do not and I can't imagine a reason for this right now.

So maybe this is the wrong report (or simply the wrong time to report this issue, but it was the first I ran into).

I created a new issue 0017974 about running a library.
Your 0017965 covers the icon issue.
Is there anything left that relates to converter? If not, I will close this issue.

There are some issues left, but they do not belong in this bug report. I will create some new bug reports for each and every issue I found.

The problems were not related to converter and are reported as separate issues.

One of these other issue I mentioned is reported under the ID 17982.

Furthermore, I am getting sporadic problems converting some of the dfm files, but these problems are not reproducable.
