[Radiance-general] X 11 trouble with OS X

[Dave Bosworth]

Hello -

I have been trying to get Radiance loaded to my OS X system (v. 10.4.11).  I am new to UNIX, so the process has been a bit rocky - but - makeall install and makeall library worked out (mostly) fine, and I changed the /etc/profile file to include RAYPATH, and everything seemed to be working fine.  Commands like genprism work and the .oct file built OK.  However, when I went to run rview I get this error:

rview: cannot open X-windows; DISPLAY variable set?
rview: fatal - cannot initialize x11

I have tried setting DISPLAY=0 and no effect.  I even went so far as to write this little ditty into  /etc/profile on  the advice of a radiance-general user:

if [ -z "${DISPLAY}" ];then echo -n
export DISPLAY=':0'
fi

also, no luck.  So, now I am begging the wisdom of more advanced users.

any advice?

thanks a million

Dave
