Hi Andreas,

On SuSe 6.3 I found:
/usr/include/malloc.h:extern int mallopt __MALLOC_P ((int __param, int __val)); 

Here is seems to be defined. No idea for you, sorry.

Mhh, once we had such ifdefs in Gmakefile. But they caused
problems on several machines.

What do you suggest for me?

I have added it. Currently hard-coded, this needs to be finished
in "configure".

I added $(PNGLIB) to the CC line.

Fixed.

Added.

Fixed.

This is not possible in a lib. So I added in main.c:

#include <math.h>

Does this help for you?

I corrected in main.c:
# include <math.h>
to
#include <math.h>

Maybe this helps?

I added in linegraph.c

#include <math.h>

I added these paths to the search path in NVIZ2.2/configure

Thanks for your comments,
