Irrlicht Tutorial 15 .irr load file code Error->PLEASE HE

hey

I am trying to load a .irr file using the 15th tutorial available.

I have used the exact same code given but have chosen a different .irr file.

However i have one strange error that I'm not really sure why I am getting it. the error is this:

: fatal error C1021: invalid preprocessor command 'def'

here is the piece of code it's referring to:

#def _MSC_VER
#pragma comment(lib, "irrlicht.lib")
#endif

any help or guidance to solving this issue would be great!

thanks

this should be #ifdef _MSC_VER

EDIT:

If you're having problems with preprocessor directives, this page gives a nice overview http://www.cplusplus.com/doc/tutorial/preprocessor/

Actually, that whole site is excellent as a C++ reference

you could set something in your ide's options to disable read-only file.

in MSVC
Tools->Options->Environment->Documents->Allow editing of....

What are you talking about?

Code: Select all

#ifndef __analysis_assume
#ifdef _PREFAST
#define __analysis_assume(expr) __assume(expr)
#else
#define __analysis_assume(expr) 
#endif
#endif

wouldn't it be crap if this has happend while debugging and some file opened and you didn't noticed you have changed something. Especially when the file has been saved (yeah got to love the automisation nowadays) and you shutdown your system due to whatever. That options is just to prevent (not 100% secure) that.

never noticed the #ifdefs in the tutorials so I thought it was changed in an included header. Thus I thought I could help here just a little bit.
