Ron,

Thank yoy very much for helping me. I really apreciate that.
At this time I am trying to compile your sources, but I found
some errors. Two of them I could fix, but about the third I am
not sure what to do exactly, I do not much about the sources,
perhaps you can help with this problem.



Bug report :

First:

In the makefile there is a little error. I think the two
lines beginning with C:\.... are there accidently.

......

radiositDEP =  $(SRCDIR)/radiosit.c \
C:\Cygnus\B19\H-i386-cygwin32\lib\gcc-lib\i386-cygwin32\egcs-2.91.57\..\..\..\..\i386-cygwin32\include\string.h
\
 C:\Cygnus\B19\H-i386-cygwin32\lib\gcc-lib\i386-cygwin32\egcs-2.91.57\..\..\..\..\i386-cygwin32\include\_ansi.h
\
 $(SRCDIR)/frame.h config.h $(SRCDIR)/lighting.h $(SRCDIR)/point.h
$(SRCDIR)/vlbuffer.h $(SRCDIR)/bbox.h $(SRCDIR)/vector.h \
 $(SRCDIR)/povray.h $(SRCDIR)/atmosph.h $(SRCDIR)/camera.h
$(SRCDIR)/media.h

.....


Second:

file f_func.c line 207

    //*(calc_stack_top)= pow(
ABS(*(calc_stack_top)),*(calc_stack_top+1));

An ansi C Compiler does not understand the // - comment and it is
confusing
because of the * after the // to. I changed it that way :

    /* *(calc_stack_top)= pow(
ABS(*(calc_stack_top)),*(calc_stack_top+1)); */

otherwise I had some errors


Third:

Here I don't know exactly what to do.

"../f_param.c", line 78: error(1164): argument of type "OBJECT *" is
          incompatible with parameter of type "PARAMETRIC *"
     if (! Intersect_Par_Box (Ray, Object, &Depth1, &Depth2, &Side1,
&Side2))
                                   ^

I put here a cast in like :

     if (! Intersect_Par_Box (Ray, (PARAMETRIC*)Object, &Depth1,
&Depth2, &Side1, &Side2))




"../f_param.c", line 501: error(1143): declaration is incompatible with
          "PRECOMP_PAR_DATA *Precompute_Parametric_Values(PARAMETRIC *,
char,
          int)" (declared at line 158 of "../isosrf.h")
  PRECOMP_PAR_DATA *Precompute_Parametric_Values (Par, flags, depth)
                    ^

This problem I think I fixed by changing the line from

PRECOMP_PAR_DATA *Precompute_Parametric_Values (Par, flags, depth)
PARAMETRIC *Par;
char flags;
int depth;

to

PRECOMP_PAR_DATA *Precompute_Parametric_Values (PARAMETRIC * Par, char
flags, int depth)

Now it finished compilation but I am not sure if the cast will do the
job
during runtime. What do you think about that?

I am looking forward to hearing from you.
