Hi,

I am using matlab compiler to launch matlab code through CGI. I am testing locally only, for the moment (MAMP on MacOSX snow leopard).

When the script is launched through CGI but, I am getting this warning :

"Warning: No display specified. You will not be able to display graphics on the screen."

whereas all is fine when I run it from the console. I tried to set the DISPLAY environment variable in the bash script calling my matlab program, but no success.

Can anyone help?

thx

G.

What is your goal? To display graphics on the screen even though the program 
has been triggered by a CGI script (which in theory could be from anywhere, 
perhaps even several simultaneously) ? Or to get rid of the warning? If you 
want to get rid of the warning include -nodisplay in the matlab options (for 
Unix.) If you want to display on to the screen, use -display followed by the 
display name in the command-line options (for Unix), and set your X 
authorization to accept connections from the web server (not generally a good 
idea.)
