I added this to testmain.ly before the \book
 parserDefine =
#(define-void-function (name val)(symbol? not-null?)
    (ly:parser-define! name val))
and got this error:

F:/Meine Noten/EigeneNoten/WeihnachtsLieder/testmain.ly:17:2 <0>: error:
GUILE signaled an error for the expression beginning here

#

(define-void-function (name val)(symbol? not-null?)


Maybe some other requirement is missing.
