[Chicken-users] Egg example
Hi all, I've decided to try my hand a writing an egg. I'm one of those people who learn best by example. But when I try to download the mpeg3 example fromk SVN I'm told the URL does not exist. Am I doing something wrong or is the tutorial wrong?I have not yet started writing an egg - I just want to see an example of how it's done.

Re: [Chicken-users] Egg example
Christian, I tried release 4 and it did not work. I then tried 3 and it did. I'm fine now, but there may be a problem with release 4. Thanks for the help.

[Chicken-users] Clojure
Hi all, I'm curious. Has anyone in the Chicken community looked at Clojure - the new Lisp-like language that ties in to the JVM?I spent some time with it last week and found it not quite ready for prime time. (I think it's more Java than Lisp) It got me thinking, however.Java is a complex abomination, but it does have one thing in it's favor - the JVM and the endless libraries you'll find there.Whenever I tell people how great Chicken Scheme is they always come back to me with the same agrument they use against Lisp - it just doesn't have the breadth of libraries needed in the real world.There are a lot of eggs, but not some key ones (PNG and GTK for instance) How do we change this and compete with the ideas behind Clojure and Scala?Scheme is a much better language.

[Chicken-users] Imlib2 Egg Question
Hi, Quick question - is there any plan to add the imlib-context-set calls to the imlib2 egg? Or in other words, how do you connect the image to a X-window? Bill ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
[Chicken-users] Re: Trouble with easyffi
Hi,
I think we're talking at cross purposes here.I thought you meant
when I compiled (installed) easyffi.
I have two old programs that worked fine on Gentoo (with I believe
chicken 3.4). Both link into Gtk. I have recently tried running a
little app to test Cairo.
All of these give me no errors with I compile them. The only error
comes when I try to run them - the 'foreign parse' error.
On the Gtk programs most of the code is just calling scheme described
call to Gtk.For instance:
#?
GtkWidget *gtk_hpaned_new(void);
void gtk_widget_set_size_request(GtkWidget *widget, int width, int
height);
#
which are used thus in chicken:
(define hpane (gtk_hpaned_new))
(gtk_widget_set_size_request hpane 1200 650))
Some of the code is actual C code snippets that are defined as this:
#!
char *get_text(GtkTextBuffer *tbuffer)
{
GtkTextIter s_iter;
GtkTextIter e_iter;
gtk_text_buffer_get_start_iter(tbuffer, s_iter);
gtk_text_buffer_get_end_iter(tbuffer, e_iter);
return gtk_text_buffer_get_text(tbuffer, s_iter, e_iter, FALSE);
}
#
If this does not help, I can put together a small app that I can send
you.One of the failing programs is my own editor and a bit too big
to send - although I have no qualms in doing so.
Again, all of this worked before moving to Xubunto and Chicken 4.0.
Could some library be missing?
Bill

[Chicken-users] RE: Easyffi
Hi again, I don't believe the problem has anythning to do with Easyffi. I think the GTK+ development libraies are messed up somehow in Xubuntu.I can't get GTK to work in C either - I get a seg fault trying to open a simple top level window! I'm using the gtk+-2.0 package for the lib reference, but it doesn't work. Seaching the web seems to indicate that others are having a similar problem, but I haven't found a good account of how you set up GTK development in Xumbuntu.This is rediuculous since the whole system is based on Gnome/Gtk! Ah, the pleasures of programming. Bill ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
Re: [Chicken-users] Chicken-setup
Thanks, that's what I needed.

[Chicken-users] Easyffi
Hi again, I'm still trying to get back into run m ode with Xubuntu and now I'm finding a problem with easyffi. I use gtk+ in my user interface and access it through easyffi.This is an old program that's worked for a long time - including in Chicken-4.0.0 on Gentoo. It compiles fine, but now I get the following runtime error: Error: unbound variable: foreign-parse Call history: foreign-parse-- The offending lines are only in the c code - I don't use 'foreign-parse' anywhere in the scheme code. Any ideas on what could be wrong? I rather like the Xubuntu distribution and would hate to go back to Gentoo.

I thought Brad told me it was patched already. I haven't verified it, been too busy. I think you have to set CLEAN_DIRECT_OUTPUT to 1 as a target property for his change to work. Is there something you need to change in the CMakeLists.txt for chicken? The workarounds for CMake 2.4.3 are fine on both MinGW and Cygwin. It is straightforward to extend them to all OSs.
