Hi,
Is it possible to use preprocessor declarations in scheme code? If say:
(c-declare #<<c-declare-end
#define ABC 1000 c-declare-end )
Is there a way to use ABC when passing a value to a c-lambda?

You must create a variable in Scheme-land too:
(define *ABC* ((c-lambda () int "___result = ABC;")))
Cheers,

I have a few header files that have quite a few of these declarations. I was wondering whether there was any easy way out, instead of going through the header files and writing a c-lambda for each one.

I think that James Long was working on some automatic ffi generating code. Maybe you can take a look at his code and see what he is doing and extract things relevant to you. Or just use what he has.

Yeah, I worked on it. So did Jeremie and Christian, and a few others. I wrote "autoffi" which is just a prototype which tries to use SILex to parse C code. This code isn't maintained but hopefully still works. Pulling out definitions should be achievable.
http://github.com/jlongster/autoffi
Jeremie wrote a different program which I think used SWIG to parse C code.
http://github.com/jlongster/gambit-ffi-generator
Pulling out definitions is probably the easiest job for automatic FFI generation. Hopefully you can get something to work from either of these projects.

Sorry I did not mean to discredit anyone. I just noticed once before on your site under software autoffi or some such.
