Trying to convert a project from Delphi
lazarus / 13-General

Hello,

I'm just another Lazarus newbie trying to convert a project from
Delphi.
My first trouble comes when I Lazarus told me it aborted the
conversion of the .dpr file:

Hint: * Conversion du fichier C:\cygwin64\home\root\Proj01\serverz.dpr
*
Hint: Codage modifié de utf8bom en "UTF-8"
Hint: Conversion abandonnée.

How can I help Lazarus to complete the conversion ?

Thanks in advance

Is there no error message?
Can you copy the whole project here?
Lazarus version?

I haven't seen any error messages.
Lazarus version is 1.6.4, fpc 3.02

The whole .dpr file:

That is NOT a dpr file.... That's an msbuild project.

It was a .dproj file I renamed to .dpr...

I suppose I have to create by hand a Lazarus project...

Thanks for your answer

No, you should not have opened the msbuild project, but the main dpr
file. There's nothing to rename. There's always a dpr in a Delphi
project. And it contains pascal code, not xml.

Ergo, you started with the wrong file. Don't rename anything. Lazarus
will create an lpr (lazarus main project file) and an lpi, (its
buildscript)

Best to copy the original Delphi project to a new empty directory. As
Thaddy says, don't rename anything. Delete everything in the previous
directory where you renamed files etc. and remove that directory.

Then you want Tools > Delphi Conversion > Convert Delphi Project to
Lazarus Project.
In the Open dialog that appears navigate to find the .dpr file of the
Delphi project you want converted. Accept all the defaults offered and
Lazarus does a good job of conversion.
Any glitches, come back here, but 9 times out of 10 the converter
works better than you might expect, given the complexity of the
hurdles it has to overcome in translating Delphi code and .dfms from
so many possible Delphi versions. Only if the code is severely
Windows-dependent with lots of API calls and the like (or depends on
lots of third party components for which the source is unavailable)
will the conversion sometimes fail to give you a compilable result
that needs tweaking by hand (or rewriting from scratch to be cross-
platform).

One finally send me the missing .dpr file, and Lazarus converted it!
Many thanks for the explanations!
