hello, i have problem i do not understand when inserting a file in a module, things i never done before:
(define-module (matrix) #:use-module (oop goops) #:use-module ((guile) #:select (*) #:prefix orig:) #:export (<matrix> matrix matrix-v) ) (define scheme-plus-path "/Users/mattei/Dropbox/git/Scheme-PLUS-for-Guile") (include (string-append scheme-plus-path "/Scheme+.scm")) ... i get this error: scheme@(guile-user)> (use-modules (matrix)) ;;; note: source file /usr/local/share/guile/site/3.0/matrix.scm ;;; newer than compiled /Users/mattei/.cache/guile/ccache/3.0-LE-8-4.6/usr/local/share/guile/site/3.0/matrix.scm.go ;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0 ;;; or pass the --no-auto-compile argument to disable. ;;; compiling /usr/local/share/guile/site/3.0/matrix.scm ;;; WARNING: compilation of /usr/local/share/guile/site/3.0/matrix.scm failed: ;;; In procedure string-prefix?: Wrong type argument in position 2 (expecting string): (string-append scheme-plus-path "/Scheme+.scm") While compiling expression: In procedure string-prefix?: Wrong type argument in position 2 (expecting string): (string-append scheme-plus-path "/Scheme+.scm") but it works if i replace the string-append by the string already appended : (include "/Users/mattei/Dropbox/git/Scheme-PLUS-for-Guile/Scheme+.scm")
