1. Cffi-devel Lisp With Cffi For Mac

I'm trying to install cffi package into sbcl. First, I tried clbuild that is recommended on the cffi installation page. When I tried to run: clbuild quickload cffi I was given an error saying: The function ASDF::SOURCE-REGISTRY is undefined. I then tried asdf-install, it end up complaining about Component 'cffi-examples' not found Any help on this would be appreciated. UPDATE For asdf-install, I'm running sbcl with slime.

It seems that whenever it complains about a component that is missing, that component is actually installed. I just have to abort the debugger and restart Emacs, start slime, and do that install again, and it will finish successfully. If I don't run it with slime, just running it inside sbcl prompt in terminal, it will keep complaining about the component missing nonstop. So to get cffi installed with asdf-install, I had to restart Emacs for about 4-5 times. I'm not sure if there is configuration issue with sbcl? I suppose I should ask this question in different thread.

Here are the exact steps for manual installation under Windows 7: First, download and install SBCL from: Then download and untar ( tar xzf.),. Then, start SBCL, load ASDF, and add the paths to these systems to asdf:.central-registry.: C: Program Files Steel Bank Common Lisp 1.0.49sbcl.exe -core sbcl.core This is SBCL 1.0.49, an implementation of ANSI Common Lisp.

» » CL-PNG CL-PNG CL-PNG is a Common Lisp library for reading and writing PNG (Portable Network Graphics) files. It is currently maintained by, and new versions can be found at the CL-PNG homepage,.

This manual is in the public domain. Table of contents:. CL-PNG 0.6 has been verified to work on the following platforms. SBCL on Linux (x8664), Mac OS X (i386 and x8664), and Windows (i386). Clozure CL on Mac OS X (ppc and x8664). CLISP on Linux (x8664).

Allegro CL on Mac OS X (i386 and ppc). LispWorks on Mac OS X (i386) Please success/failure on other platforms. Since version 0.5, CL-PNG uses a foreign function interface to call, the official PNG reference library.

As a result, it benefits from all the effort that has been put into that library: CL-PNG is much faster than before, and better able to handle corner cases. The interface is likely to change in future versions. Please on your experience with the current interface. The current version has the following limitation:.

Alpha channels and metadata (such as timestamps and comments) cannot be included when writing an image. They are silently ignored when reading an image.

Cffi-devel Lisp With Cffi For Mac

News in version 0.6:. Can now read from and write to Lisp streams, even those without file descriptors. Fixed bug causing crash on 64-bit platforms. Can now read, write, and represent 16-bit images. (Previously downscaled to 8 bits on read.).

Fixed bug in reading of 1, 2, and 4-bit images on CCL DarwinPPC. The easiest way to download and install CL-PNG is using QuickLisp: (ql:quickload 'png'). Version 0.6:. on GitHub. CL-PNG depends on (your operating system distribution may have a separate package, called libpng-dev or something similar, that contains the required png.h header file). CFFI in turn depends on,. The easiest way to download and install CL-PNG and the Lisp libraries that it depends on is using: (ql:quickload 'png') If you do not want to use QuickLisp, install the dependencies, then symlink png.asd (and, if you'd like to run the unit tests, png-test.asd) to one of the directories in.

Then, evaluate (asdf:oos 'asdf:load-op '#:png) in order to compile and load CL-PNG. On Mac OS X 10.4, you may discover that the C compiler does not accept the -m32 option that attempts to pass to it. You will need to work around this, for instance by setting cffi-grovel::.cpu-word-size-flags. to the empty string. If you would like to run the unit tests, evaluate (asdf:oos 'asdf:load-op '#:png-test) followed by (lisp-unit:run-all-tests #:png-test). ( rotate ( input-pathname output-pathname) 'Read a PNG image, rotate it 90 degrees, and write it to a new file.' ( ( ( old ( ( input input-pathname:element-type ' ( 8)) ( input))) ( new ( ( old) ( old) ( old) ( old))) ( m ( old))) ( ( i ( new)) ( ( j ( new)) ( ( k ( new)) ( ( new i j k) ( old j ( m i 1) k))))) ( ( output output-pathname:element-type ' ( 8):direction:output:if-exists:supersede) ( new output)))).
