Error when loading forms in Lazarus - Unknown property: "LCLVersion"

I've found the LCL Version thing too... And it frustrates me... Because I have one PC I have SVN on, and one old 0.9.24 version. If I want to edit a project after I've worked on the SVN, I've got to reopen all my .lfm's and remove it.
Can we make that it doesn't add it to EXISTING forms, and only add it to new forms?
Regards,

The version information was added with 0.9.25. The 0.9.24 does not know
the
property.
It means you created/edited the form with a 0.9.25 IDE and opened them in a
0.9.24 IDE.
To use a 0.9.24 IDE you must remove the LCLVersion line from the lfm files.

The version information was added with 0.9.25. <http://0.9.25.>
The 0.9.24 does not know the
property.
It means you created/edited the form with a 0.9.25 IDE and opened
them in a
0.9.24 IDE.

It should be better to have a config option:
(X) Add version info to all LFM (default)
( ) Add version info to new LFM
( ) Do not add version info to LFM files

It is not an option!
The same would happen if we had published a property in SVN.

It means you created/edited the form with a 0.9.25 IDE and opened them in a
0.9.24 IDE.
To use a 0.9.24 IDE you must remove the LCLVersion line from the lfm files.
And strictly speaking, the fact that forms are not forward compatible is of course Delphi compatibility :-)

I agree that it is definitely a good attribute to have. It's just a little bit irritating at the moment. But it will all be ironed out if 0.9.26 ships. Then we can just say, Upgrade! :-)

There are some tipps how to use newer forms on old IDE's.

> forms?
No. Because:
It can only be omitted if no component class was used on the form, that
added/renamed/deleted/changed its published properties between your old IDE
version and your new IDE version. But to find this out, you need the
version
number, which is contradictory.
I know that the LCLVersion creates a break for something that it wants to
fix.
But for all future versions 0.9.26,28,... it will help to reduce the
problems of
changed properties.

Hi Mattias,
I've just spent about 2 hours (approx or even more!!!) using Lazarus to try to sort out this problem!
I think that a major problem (for me anyway!) is that I don't understand the concepts of the difference between "Lazarus project (*.lpi)" and "Lazarus Project source (*.lpr)". In my confusion I've actually created BOTH in the same folder and using the same units and forms and resources. THIS IS A NIGHTMARE!!!! { But I'm trying to smile about it }
Can someone please or .lpr file(s) and help me to compile and run them?!? E.g. I would like to send them as an attachment to a person who would be kind enough to help me sort out this f*cking mess!!!
Mattias, in the past has been kind enough to receive the files as an attachment... and I would be happy if he would like to do that again. HINT HINT ;-)))
This is really not very good for my mental health... and I have schizophrenia and take medication regularly (and that really works well... at least most of the time)... What I'm saying it that sometime having a programming issue like this can drive me off the deep end! :-( Computing and programming are just hobbies for me. I use Lazarus because I come from a background where I used to use M$ Windowz and Delphi 5 and 7... And Lazarus appeals to me because it's sort-of a Delphi clone. (Now I've given M$ Windowz the flick and my desktop pc is totally Linux Kubuntu -- and its a very good and recent machine e.g. good specs!)
And I think I'll stop this message here.
Best Wishes and Hoping that someone will take pity on me and decide to help me Fond Regards,
PEW
