Well, you can not use it in a CGI application. Interfaces is for GUI
support. A CGI by definition has no GUI.
But in Windows works perfectly, the error is only in Linux (Ubuntu). :(
That's just a coincidence. Don't use unit interfaces in non GUI
applications.
It makes no sense to use it. Why would you need that ?
Hm..., I need of Interfaces to use my new function (LSStreamToBase64Str
[http://code.google.com/p/lazsolutions/source/browse/trunk/Core/LSUtils.pas#546]).
For a better explanation, see the simple project in attached (rename
from "LSStreamToBase64Str_CGITeste.zip_" to
"LSStreamToBase64Str_CGITeste.zip"). If possible, test the TestWithLRS
demo.
I've looked at that method. It does not rely on any visual code, so I'd
suggest you to move those methods that don't use any GUI related code
(e.g. dialogs, etc) to another unit where only units from RTL and FCL
are included. This unit can then be used within your CGI application
without problems.
I've looked at your unit again:
The only functions that rely on GUI seem to be LSOpenDialog and
LSGetWorkAreaRect. You should move those to a LSGUIUtils unit (or
however you want to name it) and remove the units Classes, Dialogs,
ExtDlgs and Forms from the uses clause of LSUtils.
Another note on one of your functions:
You are aware that LSCurrentUserName will return the user who COMPILED
the unit, not the one that is running the application?
If you want to get the environment variable at runtime you should use
GetEnvironmentVariable (for documentation see here:
http://www.freepascal.org/docs-html/rtl/sysutils/getenvironmentvariable.html
). You also don't need to use the "%...%" when using that function.

Sven
