Re: [MacPerl] Troubles using GD examples

["John C. Potter" <jcp@flash.net>]

Paul,

Thanks for the reply. One of the more obvious things I was missing was the
fact that all I have installed is the appl (See MacPERL README of the
install).

I needed to pick among bigappl or appl_cfm68k.  I believe the other choices
dealt with MPW which I don't currently have running.  I chose bigappl.

So, I am getting closer to running the GD demos.  The DynaLoader now recognizes
the GD module.

BUT.....it now bombs after executing the following lines, especially the
last line (in other words, the script executes all the way up to printing
out the gif image!!  Instead of an image, garbage is printed to a console
window.:

.
.
.
binmode STDOUT;

# print the image to stdout
print $im->gif;


I took the first assumption that binmode was not functioning on my machine.
I tried commenting out the binmode line.  This doesn't work either.
Is there something else I am missing?

Thanks,
John
