Here''s the deal, in a nutshell... When I build my project, which is very small and I just started, I get 3 errors... d:\ms visual studio\vc98\include\math.h(310) : error C2143: syntax error : missing '')'' before ''constant'' d:\ms visual studio\vc98\include\math.h(310) : error C2143: syntax error : missing '';'' before ''constant'' d:\ms visual studio\vc98\include\math.h(310) : fatal error C1004: unexpected end of file found I thought it may be a syntax error, elsewhere, but when I remove math.h and all references to the very few objects that use it so far, it compiles and runs fine. Anyone ever had a similar problem? Running VC++ 6.0 on WinXP Pro.

I already checked all of the syntax...

I did find it though... it was indeed a #define. Apparantly _X, _Y, and _Z are already defined in math.h... sucks, huh?

Generally you shouldn''t begin your custom defines with an underscore as (IIRC) underscored defines are reserved for either standard usage or for implimentation specific defines.

Actually, _X and _Y are used for arguments in a lot of the inline functions in math.h. My having it defined as 0, 1, 2 for _X, _Y, and _Z was causing some problems.

#ifndef
#define
#elseif
But you should check if everything went the first branch .............

Underscores followed by a capital letter are reserved for the implementation. A pedantic compiler sh/would reject all such user code.

_z is technically OK to use, but doesn''t fit the MACRO rule. Does you project have a prefix? Use PREFIX_Z etc...
