Re: GOOPS question

[Damien Mattei]

i use now the good way to loadmodule:

scheme@(guile-user)> (set! %load-path (reverse (cons "." (reverse
%load-path))))

scheme@(guile-user)> %load-path

$1 = ("/usr/local/Cellar/guile/2.2.6/share/guile/2.2"
"/usr/local/Cellar/guile/2.2.6/share/guile/site/2.2"
"/usr/local/Cellar/guile/2.2.6/share/guile/site"
"/usr/local/Cellar/guile/2.2.6/share/guile" ".")

scheme@(guile-user)> (use-modules (gvector))

;;; note: source file ./gvector.scm

;;;       newer than compiled
/Users/mattei/.cache/guile/ccache/2.2-LE-8-3.A/Volumes/Mojave/Users/mattei/Dropbox/git/library-FunctProg/gvector.scm.go

;;; note: auto-compilation is enabled, set GUILE_AUTO_COMPILE=0

;;;       or pass the --no-auto-compile argument to disable.

;;; compiling ./gvector.scm

;;; compiled
/Users/mattei/.cache/guile/ccache/2.2-LE-8-3.A/Volumes/Mojave/Users/mattei/Dropbox/git/library-FunctProg/gvector.scm.go

scheme@(guile-user)> (define c2 (make <gvector>))

;;; <stdin>:4:11: warning: possibly unbound variable `make'

<unnamed port>:4:0: In procedure module-lookup: Unbound variable: make


Entering a new prompt.  Type `,bt' for a backtrace or `,q' to continue.

scheme@(guile-user) [1]>

module <gvector> was not in %load-path
but yet another problem that does not exist outside module when simply
including files....
