[SOLVED] RequireDerivedFormResource problems
lazarus / 31-LCL

Hi there everyone,

Once in a while I run into a problem with Lazarus that reminds me of
its rough edges & drives me up the wall. I'm working on an application
that has been working fine for some years now. All of a sudden, when I
start the application after compilation, I get an error saying

Form resource TfrmProject1 not found. For resourceless forms,
CreateNew constructor must be used. See the global variable
RequireDerivedFormResource.

and the application terminates!!!! 

I had already addressed this problem when the transition to using
RequireDerivedFormResource first appeared. RequireDerivedFormResoure
:= True in my project's lpr file.

The project's resource file is in the same directory as the executable
so I don't know what Lazarus is complaining about!

Any advice on how to get around this problem?

Thanks,

JD

You are probably missing the
Code: [Select]{$R *.lfm}

in the forms unit.
This can haenn if you switch from "old style" (*.lrs) to "new style"
resources in an existing program (Lazarus does not add it
automatically).

Thanks a million Bart. That was it. I may have deleted it by mistake
because it was there before. Must be due to too many coffee fueled
late nights coding.
