My advice is just live with it - at least when compiling the example code.
To get rid of the warning you can go into the code and do some ugly hacking,
eg:
pfStringMat(GSetStrings[EXTRUDED], *((const pfMatrix *)&mat));
Don't ask me why you can't just cast to (const pfMatrix) - some weirdness
with the compiler. There's probably a more elegant way to do it. In any
case, this generates exactly the same code as the original. What you need
to ask yourself is whether a compile with no warnings is more important than
being able to read the code.
If it's just the warning that bugs you though, you can add 1164 to the -woff
list. Or use C++, which handles this stuff much more cleanly.
Have fun,

Subject: Compiler warnings
Hallo,
I've just started using Performer and decided to compile the examples in
/usr/share/Performer/src/pguide/libpf/C
They compiled OK but I got a lot of compiler warnings of the following type:
/usr/bin/cc -DN32 -DIRIX6_5 -I/usr/include -fullwarn -nostdinc
-I/usr/include -mips3 -n32 -O --MDupdate Makedepend -woff
1685,515,608,658,799,803,852,1048,1233,1499 -c ../text3D.c
cc-1164 cc: WARNING File = ../text3D.c, Line = 96
Argument of type "float (*)[4]" is incompatible with parameter of type
"const float (*)[4]".
pfStringMat(GSetStrings[EXTRUDED], mat);
^^^
This is true for many other function calls with pfMatrix as an argument
e.g.:
pfPostTransMat(), pfLoadMatrix(), pfMultMatrix().
I guess removing -fullwarn would hide this problem, but like the writers of
the original Makefile in the pguide directory, I like to use this feature.
Is there some way of eradicating this warning rather than ignoring it.
Many thanks,
Guy
