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 -- http://galinha.ucpel.tche.br:8081/blog/blog.ssp ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
[Chicken-users] unbound variable: export
I'm trying to build an egg, but can't get a working shared library: csi cackle-base.so Version 2, Build 3 - linux-unix-gnu-x86 - [ dload ptables ] (c)2000-2005 Felix L. Winkelmann ; loading cackle-base.so ... ; loading /usr/lib/chicken/http-server.so ... ; loading library regex ... ; loading /usr/lib/chicken/http-utils.so ... Error: unbound variable: export csi Version 2, Build 3 - linux-unix-gnu-x86 - [ dload ptables ] (c)2000-2005 Felix L. Winkelmann #;1 (load-library 'cackle-base) ; loading library cackle-base ... Error: (load-library) unable to load library cackle-base #f The library cackle-base is a base file, which includes three other files. All these files have their own use and declare export statements. Is that a problem? The unbound variable error seems to occur, when it comes to the second included file. -- Gottes Segen!

Re: [Chicken-users] unbound variable: export
How exactly are you using export? $ cat cackle-base.scm (define-extension cackle-base) (include cackle-server.scm) [...] $ cat cackle-server.scm (use http-server http-utils) (declare (export cackle:server)) [...] If you compiled cackle-base.scm with the -shared option, load-library will not work, BTW. I'm confused about load-library now, because i thought, this is exactly what it is used for?? -- Gottes Segen!
