So by the time you get done pleasing everybody, which is what needs to happen for projects to become standardized, stable, well supported, and widely adopted, it's not lightweight anymore. At best it's middleweight and more typically it becomes heavyweight. The problem is the pleasing everybody part. I've read that GUI thread and realised that a consensus was not achieved by the Elder Ones. My need for a GUI is urgent (I almost switched to PLT). So, instead of jumping into that endless discussion, I started hacking my own egg, which primarily address my needs. The IUP API is so small I had a working egg in a couple of days, and since I need just a few widgets besides an OpenGL canvas, it's perfect for me.

[Chicken-users] Problems with chicken-setup in MinGW
Hallo, I tried to install the crunch egg. It requires the format-modular egg, which tries to install an object file (format-modular.o). Chicken-setup, unfortunately, translates the file name to format-modular.obj, which does not work with MinGW. So I guess this is a bug. :-) Cheers, -- -alex http://www.ventonegro.org/ ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users

Hallo, On 4/2/07, Graham Fawcett [EMAIL PROTECTED] wrote: I guess there are so many ffi choices because it must be a pain to write pure C extensions, judged by what I've seen from chicken's output. No, I don't think it follows that there are many FFI choices because writing pure C extensions is a pain. It was just a thought. Don't judge the complexity of pure C modules by the scary appearance of CSC-generated, CPS-mangled C code. Instead, write a pure C module or two, in a natural style, and find out for yourself that it's not that hard at all. But I still have to sum up the sizes of everything I'm gonna need to call C_alloca, then to set bit types in the right places of the allocated memory, the functions have a variable number of arguments etc., etc. I'm not saying that this is a design flaw or something. It's just that I'm used to write Lua extension modules, and it's even fun! But of course Lua is only interpreted and was designed from the beginning to be easily embeddable and extended. And chicken has lots of FFI features that ameliorates this problem if one mixes C and Scheme. It's just a different way of doing things.
