Constructor must be init - how to get rid of this?
lazarus / 65-FV-Textmode IDE

I have a Linux console/framebuffer/non-x project so why using X and
Lazarus to develop while I don't want any X to be there? I tried to
move the project to fp

Then I got "Constructor name must be init" compiler error... and I
didn't find where fp keeps fpc command line parameters to to change
this behavior. Where I should search for this?

This is Raspberry Pi OS, 64-bit ARM.

i thinked what this error is for "Object" types only... anyway, this
is next FPC option:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i -Ss      
 Constructor name must be init (destructor must be done)

Yes, I know, this is -Ss, but where fp keeps this so I can remove this
option from there?

Either {$mode delphi} or {$mode objfpc} will solve the issue.
Other modes, like {$mode tp} or {$mode fpc}, the default, will trigger
it. That's because in these modes the objpas unit is not loaded. That
is documented.
It is a bit strange, since the objfpc unit pulls in classes, but old
school objects do not need it, provided constructor /destructor are
named init/done.

No, the -Ss switch is independent of the mode. The {$mode ...}
directive will not reset it.

The message only shows up if objpas is not included.

There is {$mode objfpc}  at start of the main program and the unit
which has the error. If not, this thing doesnt even accept a class.

You're wrong. This message only shows up if the -Ss option is given to
the compiler, cause that's how it's implemented in the source. Just
search for cs_constructor_name and you'll see that it's only changed
with the option (or with -S-, but that's only for disabling it).

The text mode IDE keeps the settings in a fp.cfg file, though I don't
know right now which locations the IDE looks for (one at least is the
current directory from which the IDE is started).
