Hello, i found a bug with zeos and foweb (cgi application),  the link
of that bug is

http://zeosbugs.firmos.at/view.php?id=270

the problem is that some developers dosnt know enough of fpc
architecture. If somebody can help would be nice.

 his last post is :
========
I must admit i don't know enough about the FPC architecture. All the
errormessages do point me to used controls of the TZUpdateSQLEditor
Forms or something like this. May i ask you for more expierences on
this domain?

With delphi we use different Packages for each Layer: Core, Plain,
ParseSQL, Dbc, Component, ComponentDesign.

Annoying for me is that the messages are less helpfull. They do only
point me to for CGI inavailable functions but i must admit i'm
currently not really able determine the Unit which directly points to
this issue.

Any ideas or suggestions?
========

I'm not sure how this error as, but you can try creating controls at
runtime? maybe this would help to avoid the error.

Add Interfaces to the .lpr's uses clause. Use NoGUI interface for web
application.

While the proposed solution should work, is not optimal.

Try removing the unit zcomponent from the uses clause of your main
project file (.lpr). It worked here

The reason is that zcomponent is a package file (not necessary to work
at all) that depends of LCL controls. This forces the requirement of a
LCL interface, so adding NoGUI interface works but with a huge, and
not needed, dependency. Compare the file size of the  compiled program
with Interfaces unit plus NoGUI and as a proposed.

i tried but no compiled. same error. it needs interfaces

Somehow you still have a dependency to LCL in your project

Attached a cgi program with zeos that compiles fine
