How do I fix Delphi Prism ASP.NET error: "Parser Error Message: 'Oxygene' is not a supported language"

Question

I have written an ASP.NET web application (not site) in Delphi Prism. Everything works fine on my devlopment machine, but when I install it on a test server I get the following error:

Server Error in '/MyApp' Application.
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.

Parser Error Message: 'Oxygene' is not a supported language.

Source Error:

Line 1:  <%@ Application CodeBehind="Global.asax.pas" Inherits="MyApp.Global_asax" Language="Oxygene" %>


Source File: /MyApp/global.asax    Line: 1

I've read everything I can find on the web. Several articles mention a RemObjects page (http://devcenter.remobjects.com/articles/?id={B549AFB8-04C8-4574-B185-30DE14369E66}) which unfortunately, no longer exists.

Some links suggest that you can just change Language="Oxygene" to Language="C#". Trying this produces a different error:

Compiler Error Message: CS1061: 'ASP.login_aspx' does not contain a definition for 'ForgottenUsernameLinkButton_Click' and no extension method 'ForgottenUsernameLinkButton_Click' accepting a first argument of type 'ASP.login_aspx' could be found (are you missing a using directive or an assembly reference?)

Anybody else experienced these problems?

This has been discussed in Delphi.Prism newsgroups, accessible via NNTP and also via web interface. Namely, the link to discussion is https://forums.codegear.com/message.jspa?messageID=51211 — Eugene Mayevski 'Callback, Jan 10 '11 at 22:02
@Eugene - I've seen the thread, but it doesn't contain a solution to this problem. I'm using ASP.NET web application, not a web site. — norgepaul, Jan 10 '11 at 22:07
there were more discussions on the topic during Autumn, that is the thing I remember for sure. I.e. you probably will have more success asking in newsgroup - the authors (Marc and other guys from RemObjects) answer in newsgroups quite actively. — Eugene Mayevski 'Callback, Jan 10 '11 at 22:11

There are several ways to solve this issue. The easiest way: If you control the server is by installing the command line edition.
Another way is precompiling, it: You'll need the Web deployment Project to do this. When you do this, make sure to uncheck the updatable option.
With the august 2010 build you can copy the .compiler, .codemodel, .pdb, .cirrus to Bin/, then to your web.config add something like:

<system.codedom> <compilers> <compiler language="Chrome" extension=".pas" type="RemObjects.Oxygene.CodeDom.OxygeneCodeProvider, RemObjects.Oxygene.CodeModel, Version=4.0.0.800, Culture=neutral, PublicKeyToken=3df3cad1b7aa5098" /> <compiler language="Oxygene" extension=".pas" type="RemObjects.Oxygene.CodeDom.OxygeneCodeProvider, RemObjects.Oxygene.CodeModel, Version=4.0.0.800, Culture=neutral, PublicKeyToken=3df3cad1b7aa5098" /> </compilers> </system.codedom>

Note that in this requires that the version number (4.0.0.800) has to match the dll version of the CodeModel dll you have.

Excellent answer Ck. I went with #2 and it seems to work fine so far. — norgepaul, Jan 19 '11 at 14:50
Do you really need the .pdb? I thought this is just debug information? — Sebastian P.R. Gingter, Feb 12 '11 at 12:03
You'd only need the .PDB dll id you wanna compile your ASP.NET site with debug info. which might be useful. That said, Oxygene 5 iirc eliminates that dll, so the point is moot for newer versions of the compiler. — marc hoffman, Dec 12 '11 at 14:22
