Ok. I did the above (modifying "sndlin" to "sndlib", and the last
"premake4" to "premake4 --jack"
It seemed to compile fine, with just a few warnings. The full compile
log is here:
Then, when I ran Grace, in my terminal I saw the following errors:
When I ran either the code I posted in my original message or your
suggested modification with "format" instead of "print", Grace reported
replied "syntax-error" when I executed the "(sprout (foo))" line, though
no complaints when executing the definition of foo.
Also, at the same time it reported the syntax-error in the Grace window,
on my terminal I saw Grace output:
;sprout: unbound variable
; (sprout (foo))
This is definitely better than going in to an infinite loop and hanging
my machine, but now I think I'm a bit at a loss as far as understanding
what's going on here. Which variable does Grace think is unbound? And
what is the source of the syntax-error?
