Hi there,
in my quest to get lilypond working with GUILE 2+, I've hit another
stumbling block.
In order to make compilation with GUILE 2+ working, we have to move
away from runtime symbol definition (ie. module-define! calls).
In the code below, it looks like only one of the two definitions in
the body of my-macro-new takes effect. Is this expected, and if so,
why?
(defmacro-public my-macro-old (command-and-args . definition)
(module-define! (current-module) 'x1 "I am X1\n")
(module-define! (current-module) 'x2 "I am X2\n"))
(defmacro-public my-macro-new (command-and-args . definition)
`(define p "i am P\n")
`(define q "i am Q\n"))
(my-macro-old 1 2)
(my-macro-new 1 2)
(display x1)
(display x2)
(display q)
(display p)
thanks,
