I must be a c++ header.
If you want to use these in functions in an objective-C code use
the file ending of .mm for the Objective-C++.
Thanks,

Unfortunately, ProjectBuilder refuses to compile the header
file because
it has multiple declarations of the same function. These functions have
different arguments, however.
Here's a snippet:
//Function #1
extern void sgMakeCoordMat4 ( sgMat4 dst, const SGfloat x,
const SGfloat
y, const SGfloat z,
const SGfloat h,
const SGfloat
p, const SGfloat r ) ;
//Function #2
inline void sgMakeCoordMat4( sgMat4 dst, const sgVec3 xyz, const sgVec3
hpr )
{
sgMakeCoordMat4 ( dst, xyz[0], xyz[1], xyz[2],
hpr[0], hpr[1], hpr[2] ) ;
}
Here are some of the errors:
/Users/jmorris/Documents/L3D/SG Library for OS X/sg.h:135: conflicting
types for `sgMakeCoordMat4'
/Users/jmorris/Documents/L3D/SG Library for OS X/sg.h:132: previous
declaration of `sgMakeCoordMat4'
/Users/jmorris/Documents/L3D/SG Library for OS X/sg.h: In function
`sgMakeCoordMat4':
/Users/jmorris/Documents/L3D/SG Library for OS X/sg.h:137: incompatible
type for argument 2 of `sgMakeCoordMat4'
/Users/jmorris/Documents/L3D/SG Library for OS X/sg.h:137: incompatible
type for argument 3 of `sgMakeCoordMat4'
I would guess that this has something to do with the namespace not
wanting to allow two same names. I thought that you were supposed to be
able to do this in C, provided there were different arguments.
Is this a
build setting or something? I thought you could use Obj-C and C in the
same project. :/
Thanks for any help.
