I would be happy to try to resolve any issues or add any extensions that may be required for easy integration with gambit if the gambit developers are interested. The published version of the library system does indeed work with gambit (along with some 10 other implementations that I used for testing it), but it does not provide any of the extensions that these implementations provide. It's also quite old. The current version used in ikarus provides more functionality (e.g., separate compilation), more robust error reporting, and is substantially faster; but it needs to be cleaned up before publishing. Anyways, if you guys are interested, let me know. Aziz,,,

I have some experience using both those libraries. Ghuloum's library is written in R6 scheme. It works fine out of the box, but I had some difficulty in modifying it to export some of Gambit's extensions. As for Andre's, his will not work out of the box with Gambit. I worked with him on creating a compat-gambit.scm so that it will work with Gambit. I've put it all up as a tarball at http://smyles.com/gambit-r6rs.tgz if you want to give it a go. I have a bit of documentation on how it works if you search for "R6RS" on Gambit's wiki. I think you'll find Andre's design very interesting for your project since it's written in R5 and is built out of a simpler core. His website has more details and you should check out his comments on comp.lang.scheme. As far as the state of R6 on Gambit, it works great but the system is still rough. I've not only exposed Gambit's extensions as libraries, but I'm also able to create my own libraries, including libraries that use Gambit's ffi. There still plenty to do so if any of you are interested in hacking on it let me know. I plan on making an update to the tarball in a couple of days.

I have added it to the GSoC ideas list (http://dynamo.iro.umontreal.ca/~gambit/wiki/index.php/GSoC_ideas_list ). A few other ideas were suggested to the Snow and Gambit lists. Could the authors please go to the ideas list page and add those suggestions in the second section? Marc

Compiling with C libraries?
by David St-Hilaire 18 Mar '08

Hello! I'm trying to compile a simple file which uses a bit of math and list functions. As far as I can remember, I never used other libraries than -lgambit when compiling the generated .c files, but now, it seems that I need to add also -lm to include the C math library... If I don't I get something like: gcc -I/opt/gambit-c/current/include -o question3 scm-lib.c Question3.c Question3_.c -lgambc -lutil -L/opt/gambit-c/current/lib /tmp/ccitDGGo.o: In function `___H_standard_2d_deviation': scm-lib.c:(.text+0xcfa4): undefined reference to `sqrt' /tmp/cc7ItBpa.o: In function `___H_standard_2d_deviation': Question3.c:(.text+0xd1c3): undefined reference to `sqrt' /opt/gambit-c/current/lib/libgambc.a(setup.o): In function `___setup': setup.c:(.text+0x199d): undefined reference to `fabs' setup.c:(.text+0x19bd): undefined reference to `floor' setup.c:(.text+0x19e7): undefined reference to `ceil' setup.c:(.text+0x1a11): undefined reference to `exp' ... os_dyn.c:(.text+0x80): undefined reference to `dlclose' /opt/gambit-c/current/lib/libgambc.a(os_dyn.o): In function `___dynamic_load': os_dyn.c:(.text+0x296): undefined reference to `dlopen' os_dyn.c:(.text+0x2ad): undefined reference to `dlsym' os_dyn.c:(.text+0x2c6): undefined reference to `dlerror' os_dyn.c:(.text+0x2f8): undefined reference to `dlclose' ... /opt/gambit-c/current/lib/libgambc.a(_num.o): In function `___H__20___num': _num.c:(.text+0x1d7bb): undefined reference to `exp' _num.c:(.text+0x1d820): undefined reference to `exp' _num.c:(.text+0x1d9c2): undefined reference to `exp' _num.c:(.text+0x1de92): undefined reference to `log' _num.c:(.text+0x1e0fb): undefined reference to `log' _num.c:(.text+0x1e2bd): undefined reference to `log' _num.c:(.text+0x1e4af): undefined reference to `sin' ... collect2: ld returned 1 exit status make: *** [question3] Error 1 As you can see, there is also some other missing library (using dlopen, etc...) which I don't know of... If I add -lm on my compilation line, then I remove all the math related errors, but I still get those related to dlopen, etc... What's going on? Is this normal? I'm pretty sure that I never had to compile with -lm before. I also compile with -lutil because Marc told me to, but I'm not sure I understand why either... Thanks! ^_^ David

Bradley Lucier wrote: > It should be > > configure > make bootstrap > hg pull > make update <<<<<<<<<<<<<<<<<< not hg update > > I'm trying it now. Thank you Bradley, it worked out! I think the process is a little confusing because after doing the hg pull, hg is telling us to do "hg update" which seemed to broke my gambit sources hehe. Could it be possible for make update to include the hg pull statement, which would simplify the update process and avoid confusion? Thanks again! David

problem building gambit

Hi all! I wanted to install snow, but the installation failed. I then remembered that I saw messages about it on the snow user's list and found out that some changes to gambit were made to fix the problem. I then wanted to update my current gambit version (4.2.2) to the newest mercury version. He is what I did: $ make bootstrap blablabla... $ hg pull pulling from http://www.iro.umontreal.ca/~gambit/repo/gambit/ searching for changes adding changesets adding manifests adding file changes added 21 changesets with 87 changes to 37 files (run 'hg update' to get a working copy) $ hg update 37 files updated, 0 files merged, 0 files removed, 0 files unresolved $ make It then started the re ./configure gambit so I stopped it and did it manually. $ ./configure --prefix=/opt/gambit-c --enable-single-host blablabla $ make making all in include make[1]: Entering directory

that maybe I screwed up something by stopping the 1st build in the middle of the process so, I tried anew: $ ./make clean $ ./configure --prefix=/opt/gambit-c --enable-single-host $ make Same thing.. Is it something I forgot or wrongly did, or is this a reproductible problem? Thanks! David

passing floats in Gambit-C's FFI
by Edward Tate 16 Mar '08

16 Mar '08

I have this code in file "gl-object.ss": (c-define-type float-ptr (pointer float)) (c-define-type gl-obj (struct "GLObject")) (c-define-type gl-obj-ptr (pointer gl-obj)) (c-declare "extern void gl_obj_set_pos();") (define gl-obj-set-pos (c-lambda (gl-obj-ptr float float float) void "gl_obj_set_pos")) which calls this C code in "gl_object.c": void gl_obj_set_pos(struct GLObject *pobj, float x, float y, float z) { printf("got x: %1.1f, y: %1.1f, z: %1.1f\n", x, y, z); gl_obj_mx_set(pobj, 3, 0, x); gl_obj_mx_set(pobj, 3, 1, y); gl_obj_mx_set(pobj, 3, 2, z); } using this code in "gl-object-test.ss": (define (gl-object-test) (let ((new-quad (dynamic-gl-obj-alloc))) (gl-obj-set-id new-quad 1) (gl-obj-set-pos new-quad 0.5 0.0 0.0) <<-- relevant function (gl-obj-set-col new-quad 1.0 1.0 1.0 0.5f0) (gl-obj-print new-quad) (dynamic-gl-obj-free new-quad))) (gl-object-test) the result when the object is printed via the print function: (print function) void gl_obj_print(struct GLObject *pobj) { printf("object id: %d\n", pobj->_id); printf("object mx:\n"); int i, j; for(i = 0; i < 4; i++) { for(j = 0; j < 4; j++) printf("%3.1f ", gl_obj_mx_aref(pobj, i, j)); printf("\n"); } printf("object col: "); for(i = 0; i < 4; i++) printf("%3.1f ", pobj->_col[i]); } (result) object id: 1 object mx: 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 0.0 1.8 0.0 0.0 object col: 0.0 1.9 0.0 1.9 is not as expected. :( Is there a reason why the floats are getting borked? I've tried with float32, float64 but this didn't seem to make a difference. Any help would be greatly appreciated.

Autoconf
by jadamson＠partners.org 15 Mar '08

Dear Gambitizers, Does anyone use Autoconf? One of the supposed advantages of compiling Scheme->C is that the C is portable and therefore "compilable" by anyone with a C compiler. Autoconf seems to be the most familiar routine (I mean typing ./configure && make && make install), so it would be good to know how to set up such a distribution. For example, "make dist" would compile scheme modules in such a way that all the work left is for the C compiler. I realize this raises some questions about linking with Gambit, so I'm a little confused. Does anyone have a schema for using Autoconf that I could see? Thanks, Joel -- Joel J.

Also, in favor of an XMPP-based project... that's what Google talk uses, so it should be in their interest as well.

I don't think there is widespread of demand or interest in AMQP, not to mention awareness. Before investing much effort there, I'd look for more popular protocols such as HTTP and/or XMPP, either client or server. Given there are at least two good open source XMPP servers (ejabberd/erlang and openfire/java) the best place to begin may be with a Scheme-based XMPP client.
