[Radiance-general] Problem with avlmemi

[John de Valpine]

Hi:

Ambient value sorting, sortambvals(), can be turned of
at compile time (rather than messing with the source
code) with the following addition to rmake in the
MACH= line:

-Dtracktime=0


for example (for compilation on a linux box):

#!/bin/sh
exec make "SPECIAL=" \
        "OPT=-O2 -DSPEED=40" \
        "MACH=-DBSD -Dlinux -DDCL_ATOF
-L/usr/X11R6/lib -I/usr/include/X11 -DNOSTEREO
-Dtracktime=0 -DMAXOBJBLK=131071 -DBIGMEM" \
        ARCH=IBMPC "COMPAT=bmalloc.o erf.o
getpagesize.o" \
        INSTDIR=/usr/local/bin \
        LIBDIR=/usr/local/lib/ray \
        CC=gcc "$@" -f Rmakefile   

Regards,

-Jack de Valpine

I circumvented it by
