Irrlicht Engine

Posted: **Thu Nov 29, 2007 6:53 am**

Hi all...

Unfortunatly I am a n00b when it comes to C++ I am a java dev, but am forcing myself to learn C++ just for a project I'm working on that will need Irrlicht....

when I try to compile the CDemo (in the examples directory) I get the error

Code: Select all

CDemo.h:65: error: ‘audio’ has not been declared

I have downloaded the IrrKlang engine, and I have added this to the Cdemo makefile:

Code: Select all

CPPFLAGS = -I/home/guardian/src/irrKlang-1.0.2/include -I../../include -I/usr/X11R6/include

I am using Linux...

I have seen this error in another post, but that mentions a missing header file... my error does not mention that.

I've spent 2 full days (8 hours a day) working on this, but nothign I try seem to get it to work, and I know its because of my lack of C++

Full output:

Code: Select all

I think the namespaces etc. have changed. You wither have to use an older irrKlang version or update to the very latest SVN revisions of the 1.4 branch where Niko made some changes to the Demo:

If you are a Java dev, use jIrr, the Java wrapper for Irrlicht.

Thanks for the info.. I'll give that a shot tonight!

ultran00b, I did have a think about the java wrapper, but it just adds another layer of complication... when reading howtos etc I'd have to figure out how to "translate" everything....

good idea tho
