dyncomp enables to create C function in gauche.cgen.cise (C in S expression). This function is compiled to native code with Tiny C Compiler, so you can create a fast function.
(use dyncomp)
(define-cproc add (x::<int> y::<int>)
(let* ((z :: int))
(set! z (+ x y))
(return (SCM_MAKE_INT z))))
(define-cproc sub (x::<double> y::<double>)
(let* ((z :: double (- x y)))
(return (Scm_MakeFlonum z))))
(define-cproc print-number (x::<double>)
(printf "%f\n" x)
(return SCM_UNDEFINED))
(print (add 1 2))
(print-number (sub 3 2))
(print (map (clambda (x::<int>)
(return (SCM_MAKE_INT (+ x 1))))
'(1 2 3)))
dyncomp requires Gauche 0.8.14 or later. I have checked the environments below.
In MacOSX, Linux and FreeBSD, use gauche-package to install.
% gauche-package install --install-as=root dyncomp-0.2.0.tgz
In Windows, use build-dyncomp.cmd in the archive.
