hi all, i am a newbie to lazarus.
    i download the newst extpascal from
svn:http://extpascal.googlecode.com/svn/trunk/ extpascal-read-only
    i install the packages from folder ExtP_Toolkit, and built
fmtoextp succesfully,but when i built the example
hello_example\myproject1.lpi,the lazarus output message:
Code: [Select]D:\0laz_project\extpascal\svn_extPascal\ExtJSWrapper\Ext
.pas(7524,34) Error: Type identifier expected

the source code is:
Code: [Select]    function IsExcluded(ElseJS : TExtObjectList; X :
Integer; Y : Integer) : TExtFunction; overload;
    function IsExcluded(ElseJS : ; X : Integer; Y : Integer) :
TExtFunction; overload;
    function IsExcluded(ElseJS : TExtObjectList; X : Integer; Y :
Integer) : TExtFunction; overload;
    function IsExcluded(ElseJS : ; X : Integer; Y : Integer) :
TExtFunction; overload;
    function IsExcluded(ElseJS : TExtObjectList; X : Integer; Y :
Integer) : TExtFunction; overload;     i change it:
Code: [Select]    function IsExcluded(ElseJS : TExtObjectList; X :
Integer; Y : Integer) : TExtFunction; overload;
    //function IsExcluded(ElseJS : ; X : Integer; Y : Integer) :
TExtFunction; overload;
    //function IsExcluded(ElseJS : TExtObjectList; X : Integer; Y :
Integer) : TExtFunction; overload;
    //function IsExcluded(ElseJS : ; X : Integer; Y : Integer) :
TExtFunction; overload;
    //function IsExcluded(ElseJS : TExtObjectList; X : Integer; Y :
Integer) : TExtFunction; overload;     and rebuillt,then output
message:
Code: [Select]D:\0laz_project\extpascal\svn_extPascal\ExtJSWrapper\Ext
.pas(9831,44) Error: Identifier not found "TVarMe"
    the source code is:
Code: [Select]function GetLegendColor(ElseJS : TVarMe) :
TExtFunction;    what can i do? thanks.

I would report those bugs here:

In the meantime, you could also look at this tool for creating Web
apps:

http://web.fastermac.net/~MacPgmr/qxotica/QxoticaStatus.html

This tool uses the FCGI units from ExtPascal and they do work okay.

Thanks.

thank u Phil very much.
i have download the qooxdoo, and i'm studing its doc.
but im not sure the difference between qooxdoo and extpascal.
extpascal seams not to be updated,but if qooxdoo can quick dev web
app?

Very good question.

ExtPascal consists of auto-generated Pascal classes that wrap the Ext
JS framework. When called from browser client via Ajax, these classes
(in compiled app on server) emit JS code that is then sent to browser
and executed.

qooxdoo is analogous to Ext JS, but with the qxotica tools we're using
it to create standalone JavaScript client apps that can optionally be
used with a server-side app, for example an FCGI app written in
Pascal. Another feature of qooxdoo is that since the client is
standalone (not generated dynamically by server), it can easily be
wrapped in a PhoneGap native app. So the same JavaScript codebase can
be used both for a Web app and a native iOS or Android app.

Thanks.
