[Chicken-users] Problem with sqlite3 egg

Hello. I've been having some problems getting the sqlite3:for-each-row procedure from the sqlite3 egg to play along nicely with the iterator->stream procedure from the stream-ext egg. The iterator->stream procedure uses continuations to turn an iteration inside out: to build a lazy (srfi-40) stre

The sqlite3 egg 1.5.6+ requires the synch egg 1.0+. (At some point the .setup files for the eggs will be changed to state the required versions but for now you must do it manually.) Sorry, Kon Unfortunately, I couldn't figure out how to do this, and it seems I've made it worse :-/ I added (re

[Chicken-users] Problem with -DPIC When Building with MinGw

I have a question about building chicken 2.3 with mingw. Why does -DPIC cause mingw to fail while linking the dll? Everything works fine without -DPIC except for the dynamic extensions.

Felix, Thanks for the quick response, I still have a few questions, however, I can wait a few days. I expect that the example will probably answer most of my questions. Don't put yourself out to much though. I only worked on this particular problem to learn about static compilation with chicken

I am having a problem trying to get a small example program to compile statically. This seems to follow the what is shown in the wiki. This is just a simple test program, I am more interested in how to statically compile a program that makes use of eggs. Following is the output from my attempts.

[Chicken-users] Problem with Syntax Case in 2.0

I have been experimenting with the implementation of srfi-57 which uses syntax-case and its module system. Under Chicken-1.89 I had added (at toplevel) a procedure definition to srfi-57.scm that was used in most of the modules. To be precise it was the following: (define symbolic-identifier=

Hmm, I am getting strange behaviour in string-match: (string-match "a|b" "ax") is evaluating to ("a") (rather than #f). Interestingly, (string-match "a|b" "xb") evaluates to ("b"). However, using "(a|b)" as the regular expression fixes things. It seems string-match turns regexp into (string-app

Hi! As John pointed out, you should try a newer version (darcs repo or the latest snapshot). There still seems to be a problem when finalizers are created faster than they can be processed. Try setting C_MAX_PENDING_FINALIZERS in chicken.h to a higher value (and touch runtime.c and library.c) -
