> Could someone running 10.4 check out http://autoconf-gl-
macros.googlecode.com/svn/trunk and test the patch I've just attached
here?
I don't think that the patch works, because the compiler error
{{{
ISO C requires a named argument before '...'
}}}
means that there must be a named argument in the definition of {{{func}}},
not in the arguments of {{{gluTessCallback}}}. The patched configure check
gives the same error on 10.5. If I try to compile something like
{{{
GLvoid (*func)(int, ...); gluTessCallback(0, 0, func);
}}}
I get the correct error
{{{
warning: passing argument 3 of ‘gluTessCallback’ from incompatible pointer
type
}}}
I checked the definition of {{{glueTessCallback}}} in
{{{/System/Library/Frameworks/OpenGL.framework/Headers/glu.h}}}, which is
{{{
void gluTessCallback (GLUtesselator* tess, GLenum which, GLvoid
(*CallBackFunc)());
}}}
both on 10.5.5 and 10.4.11 (I had access to a 10.4 machine, but couldn't
compile OpenVRML because of too little memory.).
So, our problem is not the header in the OpenGL framework. I think the
problem is the X11 header in {{{/usr/X11R6/include/GL/glu.h}}}. On 10.5 it
says:
{{{
typedef void (GLAPIENTRYP _GLUfuncptr)();
}}}
whereas on 10.4.11 it says:
{{{
/* Internal convenience typedefs */
#ifdef __cplusplus
typedef GLvoid (*_GLUfuncptr)();
#else
typedef GLvoid (*_GLUfuncptr)(GLvoid);
#endif
}}}
So, it seems that {{{...}}} in the compiler error message really means
{{{GLvoid}}} (not a variadic function) and that the problem is that
{{{configure}}} uses the OpenGL framework headers, but later, during the
compilation of OpenVRML, the X11 GLX headers are used.
