<camel__>Hi everyone - I'm using guile 2.1.1 and have an issue with threading; if I call scm_c_eval_string() from guile (same thread) then it works, but if I call a function which creates a new thread and then calls scm_c_eval_string(), it segfaults <camel__>(this is apparently independent of whether or not scm_init_guile() is called in the second thread) <rjmacready>camel__: you need to call the ...with_guile... function in every thread <rjmacready>and by hidden i mean section 5.4.5 Multi-Threading <camel__>rjmacready: ok, I'll give that a go - thanks! :) <camel__>rjmacready: think I found the issue :/ <camel__>not sure if it's a bug or that I have no idea about autoconf <camel__>but I built guile without threads (ok) <camel__>this updated gen-scmconfig but not scmconfig.h <rjmacready>camel__: ah, im using the guile that came with apt-get install :) <camel__>anyway, 99% sure this will fix it (even though i'm still waiting for the build...) <tj__>is there a symbolic computation module for guile? i want to solve equations <tj__>we shouldn't be coding on christmas eve, should we? : )) <davexunit>tj__: an early chapter in SICP makes a simple symbolic computation system <davexunit>there's definitely stuff for MIT/GNU Scheme for this <davexunit>I have finally got a working sprite batch implementation for Sly. now instead of the system struggling to render a couple hundred sprites, I can easily render a few thousand on my oldish laptop: http://i.imgur.com/k0S89Oe.png <tj__>davexunit: that's dope, i'm on it, i have the book downloaded somewhere, i don't know what spirte and sly are <davexunit>tj__: the sly and sprite stuff were unrelated project updates of mine <davexunit>does anyone remember ijp's "the night before M-xmas"? <davexunit>I'm trying to find it because I got a real kick out of it ***octo_ is now known as octophore
