errors on amd64 debian unstable

Mark "Monty" Montague — 2008-10-21T07:38:02

Hi, stklos folks, I've installed stklos on debian unstable ("sid") on my amd64 laptop, and I'm seeing a few problems. It seems to work for simple things, but all the demos I tried fail with, e.g. s> ./grid1 **** Error while executing file "./grid1" Where: in try-load Reason: bad sharp syntax in `"#"' - try-load - %try-load - %load - #[closure cad3f0] - try-load - %try-load - eval EXIT make test works OK. I used the default result for ./configure, which said yes to everything except LDAP. I haven't really tried to track this, thinking you gurus may have a quick hint; I can try debugging further if it would be helpful. thanks! - M

[Announce] STklos-0.98 release

Erick Gallesio — 2008-05-18T18:21:17

This is an announce for the 0.98 release of STklos. STklos is a free Scheme System mostly conform to R5RS. The aim of this implementation is to be fast as well as light. The implementation is based on an ad-hoc Virtual Machine. STklos can also be compiled as a library, so that one can easily embeds it in an application. The salient points of STklos are: * efficient and powerful object system based on CLOS providing - Multiple Inheritance, - Generic Functions, - Multi-methods - an efficient MOP (Meta Object Protocol) * a simple to use module system * implements the full tower of numbers defined in R5RS * easy connection to the GTK+ toolkit * Perl compatible regular expressions thanks to the PCRE package. * tail recursive calls are properly implemented Changes in this release: * Replaced the C/invoke FFI library by libffi: Now GTk2 ScmPkg packages work on MacOs * Addded option --build-sync-file to ease personal ScmPkg repository maintenance * Bug fixes Homepage/Download: See http://www.stklos.net/

Two new packages

Erick Gallesio — 2008-04-18T15:26:39

Hi, I have added two packages for STklos which permits to make interfaces with GTK2. One is a simple wrapper to the GTK api, the other one permits to dynamically load XML files produced by the Glade interface builder. Files are packaged as ScmPkg and to install them you just have to do $ stklos-pkg -s $ stklos-pkg -i stklos-gtk-base $ stklos-pkg -i stklos-gtk-glade It seems to work on Linux. On MacOs, I had some problems that I cannot understand,but I'm not sure of my GTK installation. Any help on this platform would be greatly appreciated. NOTE: It will only work with the development release of STklos which is available at http://www.stklos.org/hgweb.cgi/archive/tip.tar.gz

STklos Wiki.

Erick Gallesio — 2008-04-18T15:32:20

Hi, There is now some more documentation (mainly for ScmPkg packages). It is in fact a simple Wiki which is available at http://www.stklos.org/Wiki

Extending STklos: how to deal with multible return values?

Heinrich Wolf — 2008-03-30T23:31:45

I recently implemented SRFI-25--- multidimensional arrays--- as an extension to STklos. (Has passed test suite, will be released under GPL as I find time.) The `share-array' procedure takes as third argument a procedure, which may return more than one value. To implement this I took a good look at Erick's implementation of `call-with-values' and soon arrived at a solution that seems to work--- but: I had to include `vm.h', as my code begins with: vm_thread_t *vm = STk_get_current_vm(); To me it seems an extension of STklos should not access things that are--- I suppose--- STklos internals. Did I miss something?

STklos Development tree

Erick Gallesio — 2007-09-24T12:34:57

The STklos development tree is now available at the following URL http://www.stklos.org/hgweb.cgi. The development tree is managed by Mercurial Source Control Management system. Having Mercurial on your box may help, but is not necessary if you don't plan to modify STklos distribution. In effect, the Web interface to Mercurial tree gives easy aceess to development versions in common archive formats. For instance, use the url http://www.stklos.org/hgweb.cgi?archive/tip.tar.gz always points to the last dev release in "tar.gz" format.

Is it possible to call shell script from stklos?

naruto canada — 2007-09-23T13:20:03

hi Is it possible to call shell script from stklos? Is would be quite useful, if stklos allows for calling shell script and then collect result like perl. I'm looking at Kommander, but it requires KDE, if stklos can do it, I will use stklos instead, thanks.

how to display "(quote (A B C))" instead of "'(A B C)"?

naruto canada — 2007-09-15T05:09:55

hi how to display "(quote (A B C))" instead of "'(A B C)"? I tried to look at the source code and find the following code, but it doesn't suggest an easy way to make changes. char *STk_quote2str(SCM symb) { if (symb == STk_sym_quote) return "\'"; if (symb == sym_quasiquote) return "`"; if (symb == sym_unquote) return ","; if (symb == sym_unquote_splicing) return ",< at >"; return NULL; } Thanks.

Multidimensional arrays in STklos--- or: Image Processing?

Heinrich Wolf — 2007-07-22T19:05:41

Dear STklos friends, perhaps I should just calm down. OTOH I feel I could do usefull work; so wy not make use of the energy released by ``discovering'' a deficiency in some system other than STklos. The short question is: Is anybody working on an implementation of SRFI 25, ``Multi-dimensional Array Primitives''? If so, please drop a note in this list. If you want to learn why I ask this question, please read on--- at the risk of getting bored. STk has been and is my favorite Scheme system. I interfaced it to C and did various extensions of the interpreter on a GNU/Linux system. But I am ready to move on to STklos. Less than a year ago I was looking for a way to interface various C libraries related to image- or digital signal processing (DSP) from Lisp or Scheme. Examples of such libraries are FFTW (Fouriertransform), OpenCV (Intel's open source computer vision library), or ImageMagick (A library and set of programs for dealing with images in various file formats). After some searching on the Net I came up with Lush Lisp {http://lush.sourceforge.net}. This is a Lisp with dynamic binding and a very easy-to-use interface to C--- and which has already interfaces or native procedures for image processing and DSP. But this simplicity seems to come at a cost, which shys me away from Lush. Lush has a native data type called IDX--- derived from ``index''--- which is similar to ``array'' as proposed in SRFI 25. The IDX is essential for image processing, where you deal with ``huge'', multidimensional, arrays; for example a RGB (color) image would be represented by an IDX of three dimensions. Of course, for efficency in space and time, the single array elements must be primitive C datums, such as chars or floats, not Scheme objects. So far about the background of my question. I also appreciate very much any comments, suggestions, pointers on using Scheme or Lisp for image processing or DSP. My goal is to use some Lisp derivative for studying and prototyping image processing and DSP.

stklos-ssax package release

Erick Gallesio — 2007-07-17T09:42:41

Hello Schemers, A port of SSAX, the Oleg Kiselyov's XML parser, is available as a ScmPkg package. SSAX defines itself as a full-featured, algorithmically optimal, pure-functional parser, which can act as a stream processor. SSAX is an efficient SAX parser that is easy to use. As I'm not using myself SSAX, it is very possible that I have been too much restrictive on the symbols exported by the package. Please tell me if you have problems with the current export list or if you have problem to install this package.

stklos-fuse package release

Erick Gallesio — 2007-07-13T10:47:49

Hi Schemers, A new release of the stklos-fuse package is available through ScmPkg. This new release can be installed with the stklos-pkg command. This package permits to implement a fully functional filesystem in a Scheme program thanks to the FUSE package. Two exemples of Scheme file systems are provided with the distribution: * a simple filesystem which only contain one file named "hello", and whose content is of course "Hello, world!" * a more realistic filesystem, where all the files are stored in Scheme hash tables (a directory being a hash-table whose entries are the files of this directory. The program which implements this filesystem is about 250 lines long). Since the support of ScmPkg is new, a simple session showing how to install this package is given below: % mkdir /tmp/X# create a temporary dir % cd /tmp/X % stklos-pkg --sync# Sync with servers ... % stklos-pkg -e stklos-fuse# download package stklos-fuse % make ... % make install# Install in ~/.stklos/pkg ... install done Let's use now the package % cd stklos-fuse/examples % mkdir /tmp/HASH# create mountpoint for the hashfs % hashfs /tmp/HASH# mount it % cd /tmp/HASH# An now manipulate files in our filesystem % echo Hello > foo % ls -l total 1 -rw-r--r-- 1 eg stklos 6 Jul 12 17:53 foo % cat foo Hello % mkdir bar % cp foo bar % ls -l total 1 drwxr-xr-x 2 eg stklos 0 Jul 12 17:53 bar -rw-r--r-- 1 eg stklos 6 Jul 12 17:53 foo % cat bar/foo Hello I have tested it only on Arch Linux, but I would be happy to ear that it works on other distributions. Enjoy

Stklos 0.95 install comments and fuse no compile

Matthew Welland — 2007-06-09T04:55:27

A comment: It would be helpful for Debian/[UK]buntu users to have a concise list of packages to install to enable building stklos. Since I'm sure it won't be too long before stklos 0.95 is available as a package perhaps it doesn't matter. Anyhow here is what I installed to build stklos. This is a lazy approach, install everything that has gtk, gnome and lib or dev - worked for me but I'm sure there are plenty of unneeded packages in the list. sudo apt-get install libwxgtk2.4-dev libguilegtk-1.2-dev \ libgtk-canvas1-dev libart-dev libxaw7-dev libgtkhtml2-dev \ libgtk2.0-dev libglut3-dev freeglut3-dev \ libgnome-dev libdianewcanvas2-dev \ gnome-core glade-2 glade-gnome-2 libgtkxmhtml-dev \ libzvt-dev gnome-common libgdk-pixbuf-dev \ libgdk-pixbuf-gnome-dev libgfcui-dev \ For fuse: sudo apt-get install fuse-utils libfuse-dev =============fuse============= Error that I get when I attempt to build fuse: checking fuse/fuse.h usability... yes checking fuse/fuse.h presence... no configure: WARNING: fuse/fuse.h: accepted by the compiler, rejected by the preprocessor! configure: WARNING: fuse/fuse.h: proceeding with the compiler's result checking for fuse/fuse.h... yes checking for main in -lfuse... yes /usr/local/bin/stklos-config: 30: Syntax error: "(" unexpected /usr/local/bin/stklos-config: 30: Syntax error: "(" unexpected /usr/local/bin/stklos-config: 30: Syntax error: "(" unexpected configure: creating ./config.status config.status: creating Makefile config.status: creating doc/Makefile config.status: creating doc/version.stk config.status: creating examples/Makefile **** Make package ... g -O2 -D_REENTRANT=1 -DGC_LINUX_THREADS=1 -DFUSE_USE_VERSION=22 -D_FILE_OFFSET_BITS=64 -c fuse.c make: g: Command not found make: [fuse.o] Error 127 (ignored) fuse. -lfuse fuse.o make: fuse.: Command not found make: *** [fuse.] Error 127

Sourceforge problem

Erick Gallesio — 2007-06-08T10:27:58

The 0.95 release is not available from Sourceforge as usual (but it is accessible from the STklos Web site) There was a transmission problem of the tarball and it is impossible to upload a new one for 24 hours.
