delphi 7 port gives 'error while linking'

[mezeb40]

hello, I am trying to port a delphi 7  application i wrote to Lazarus.it seems to compile ok with the dcu being created but then stops with a 'error while linking' ..I can compile and run test programs made in lazarus ok so  i am wondering why the error appears for the delphi port.
Any info appreciated.
thanks.

Well it could be many things, depending on the components used, how much WinAPI, how much Delphi specific syntax, i wold start converting small pieces of the program and see where the problem is.

What is the exact error message you get

[mezeb40]

Lots of hints/notes  with 'parameter variable/ sender not used'
.
finally an 'error:error while linking'

thanks

You can safely ignore the hints about 'Sender' not being used. It is of course quite common that this parameter isn't used in an event handler, but you can't avoid having it there

so i am left with the link error..some sort of path problem maybe?

[jesusr]

the given information is not enough.

try to copy and paste some of the last lines of the compile process, the last 10-20 lines would be fine.

Error: Error while linking

Looks like a linker error, can you compile simple programs ?

[mezeb40]

yes ,i can compile and run simple programs from lazarus ide. ie. lazarus works fine, its the port from delphi giving the error.

[Lightning]

I would try to convert small portions

[jesusr]

I don't know why, but before Lightning post of Feb 22, 2005 - 07:15 PM, I replied to mezeb40, but my reply ended in another thread. Anyway the intended response can be found in

[Lightning]

Maybe you replied just after me and the server didn't know what to do with your post

[marmin]

I also get 'error while linking' , compiling a Delphi code to Lazarus. Could it be that any of the compiler swithes is set wrongly.


I've set all Delphi-related swithes to 'on'.
I've tried anything: smart-linking on/off, etc.

Another question: is the order of units in the 'uses' list any influence on this? There has to be a simple explanation.

[marmin]

Aah.. I think I've found a solution.

If one has these problems, try this:

- make a new Lazarus unit into your Lazarus Project.
- copy and paste you old Delphi unit contents in this new Lazarus Unit.
- name and save the unit the same way you'd save a Delphi unit (but in a different folder than de Delphi unit of course).
- save your Lazarus project.

- If u don't have a Form connected with it, please remove :
{$R *.dfm} after implementation.

(this is what caused my error)
