Hi,
I believe the code modifications I described were for SunOS 5.5
I think for SunOS 5.6 it is sufficient to add a define to the
makefile -D__SunOS_5_6. (At least for root_v.2.20) This solves the
sunmath problem as well. Strangely my linker could find the sunmath
library but when I looked in all the places the linker *should* have
been looking for this file... it was not there... nor could I
find the include file.
Cheers,
Jon.
