Have you verified that the ACL2 authors would appreciate this change? You could ask the ASDF developers about the feasibility of porting this Makefile. Subscribe to the ASDF mailing list by sending an email to asdf-devel+subscribe at common-lisp.net. After subscribing, tell them what you are interes...

It sounds like you are asking for something like (maplist (lambda (x) (included x lof-l)) list) or maybe with mapl or mapcon . Another useful pattern is to write an entry function that takes the primary arguments in a simple form and does some simple work before calling the recursive core. In your c...

Hi Milky, The procedure you describe sounds right, but the results you describe are clearly wrong. The "q" to exit a restart prompt, and the REPL ",cd" to change directories are written on the Emacs side of Slime and should be portable across all CL implementations. 2011 is rathe...

Hi Damien, This looks like a possible CFFI problem on Win7. You appear to be running the latest CFFI. What version of SBCL are you using? You will probably get the best help by sending this problem report to the CFFI mailing list. To join the CFFI mailing list, send an email to cffi-devel+subscribe@...

Welcome to the fun of network sockets. There are a few options for this. Keep the socket around for multiple connections (generally preferred), set SO_REUSEADDR, or close the socket after the connection. Regardless of your primary strategy, I almost always set SO_REUSEADDR so an abnormal exit doesn'...

It looks your lisp impl is trying to parse the image into a string of UTF-8 characters.
Inevitably, some pixel doesn't parse correctly...
Pixels should stay as an array of bytes.

I suspect this function is the problem: cffi:foreign-string-to-lisp

It sounds like you have a lot of reading and practice to do.

This might help you get started, though its a proper matrix, not a list of lists.

In order for the "->" function to work, you would need to wrap the pointer in a structure that also contained the type. Something like the following untested code. (defstruct wrapped-pointer :pointer :type) (defun -> (wp field) "Get the specified field from the wrapped pointer." ...

When dealing with foreign memory, you often have to use the full foreign API.

Is there a reason you are not wrapping "cvSet3D" and using that in CFFI?
