Compiling Meroon objects and initializers
by Roger Wilson 10 Jul '11

10 Jul '11

Hi, I have a basic Scheme question. The following works as intended from my Swank REPL. How do I make it work with a compiled file? I'm trying to create a Meroon object that has an automatically created unique id each time one is created. (define *global-id* 0) (define (get-next-global-id) (let ((current-global-id *global-id*)) (set! *global-id* (+ *global-id* 1)) current-global-id)) (define-class my-object Object ((= object-id :initializer get-next-global-id))) When the Gambit setup function runs I get the error.... *** ERROR IN | object| -- (Argument 1) NUMBER expected (= #!unbound #!unbound 'get-next-global-id) Roger.

Adding multiple gsc generated C files to a project
by Roger Wilson 07 Jul '11

07 Jul '11

Hi, I'm a total scheme novice so apologies in advance for dumb questions, but can anyone give me any advice on adding multiple Gambit generated C files to a (XCode) project? I'm generating the files with 'gsc -link filename.scm', but in the setup code within the app I can only specify one module to the ___setup_params_struct passed to the setup call to Gambit. The functions from the other modules linked in are unavailable. What I'd like to do is be able to generate multiple C files and then have access to all the functions define in them from the app. i.e. the code in my app that initiates Gambit looks like the standard.... ___setup_params_reset (&setup_params); setup_params.version = ___VERSION; setup_params.linker = LINKER; // <------- Can only specify one module here setup_params.debug_settings = debug_settings; ___setup(&setup_params); What I'm actually I'm trying to do is compile Meroon in to my app. I've been developing interactively using Swank with Meroon 'included' in to it at the start of every session, but the app is running too slow (spending all it's time calling eval) so I'm trying to compile it. I can load Meroon into an interactive gsi according to Bradley Lucier's instructions and then generate a _meroon.c file, but have no way to build it into my app. Any advice on achieving that or something equivalent will be most welcome. Roger.

Gambit-C and multi-core devices
by Alex Queiroz 06 Jul '11

Hallo, Now that even smartphones get dual-core processors, I am wondering how can we use Gambit-C in a way to take advantage of that. Desktop machines with eight cores will be in widespread use soon. I know there is Termite but AFAIK it works by exchaging messages between different processes, not threads in the same process. Is anybody working on some solution for this? Cheers, -- -alex http://www.artisancoder.com/
