Just "csc -s cackle-base.scm".
I uploaded the relevant files to http://beza1e1.tuxen.de/files/cackle/
Thanks - I could reproduce the problem.
This is caused by several things working in conjunction here:
syntax-case expands each toplevel-expression completely before it is passed to
the evaluator/compiler. The "include" forms in cackle-base.scm are toplevel-
expressions and when they include the code of the other files, the
"(use syntax-case)"
in cackle-dispatch.scm will replace the (toplevel-) macro-expander by a new
one, but that will only be in effect when the next toplevel expression is
expanded. The current one is still expanded by the low-level/define-macro
expander, which handles "declare" differently than syntax-case.
A solution is to put the "(use syntax-case)" into cackle-base.scm (for example
right at the start). It also emphasizes that all included files use the same
language (i.e. chicken + syntax-case).
cheers,
felix
