[Jeff Harrington has been sharing a difficulty in running version 9
graphics programs on his Linux platform.]
In every case of failure, the program is not finding an important
argument. It's always a null while expecting an integer or procedure.
Seems like some kind of communication problem between the X-Windows
server and iconx?
No, you get this Icon error message when you are calling a procedure that
doesn't exist or wasn't linked in. From the line # and description in the
error message you should be able to tell us exactly what procedure was
being called.
>From your earlier messages we know you've built binaries with graphics
enabled, so my guess is you've got some funky problem with your Icon
procedure library.
Try the program
procedure main()
w := open("hello", "g") | stop("can't open window")
write(w, "hello, world")
Event(w)
end
to see if you have a working iconx and a valid DISPLAY environment variable.
There is tracing you can turn on, and other ways to find out more about
what is going on, if you need it.
