I'm trying to compile CGIWebSession demo, but errors as in the
attached file appear at Linking stage. What would be possible reason?

The errors are gone when I commented out SQLDBLaz from uses clause of
program file. They are not declared in the units eigher.

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 program
cgisession; {$mode objfpc}{$H+} uses  lresources,lazweb,fpWeb,fpCGI,
wmsession, sqldbsession{, SQLDBLaz}; begin 
 Application.Title:='Session Support Demo'; 
 Application.LegacyRouting:= True;  Application.Initialize; 
Application.CreateForm(TSessionModule,SessionModule); 
Application.Run;end.

Without knowing the details of what you're trying to do, I can see
that WSRegisterMenuItem etc. are defined in lcl/aliases... what
project are you trying to compile and where did you get it?

Quotewhat project are you trying to compile and where did you get it?
This is a sample file from following page. There is a title named
web2, and I downloaded the source.

That's a rather old example, and it might be better treated as a
/conceptual/ example rather than something that will still go through
the compiler. I'm particularly bothered about the way that it appears
to being in interface stuff from the LCL for some reason.

Noting that the other example doesn't import SQLDBLaz, what happens if
you try that one?

SQLDBLaz is the package unit of the SQLDBLaz package which allows you
to use the SQLDB components in the form designer. It's marked as a
runtime and design time package as such you should not add its package
unit to your program as it will pull in parts of the IDE as well and
thus in turn pull in parts of the LCL.

In fairness, he was using the example as downloaded and my very rapid
scan over the paper didn't throw light on what was going on... after
finding where those symbols were declared I was expecting it to be
some form of IDE addon.

By removing SQLDBLaz, I can run it successfully (it was originally in
the example). Probably the errors happened becuase SQLDBLaz tried to
register components to the Lazarus IDE.
I just use the sqldbsession unit. I'm looking for methods to overwrite
its initsession and initresponse procedures using helpers to fit for
my purposes.
