Re: [Chicken-users] libsvm egg install problem
Sorry about not having a good error handling. And not having a nice document. You are always welcome to write one. I could try any easy solution.

[Chicken-users] libsvm egg
Hi all! I made an wrapper egg for libsvm. http://www.csie.ntu.edu.tw/~cjlin/libsvm It's pretty straightforward based on SWIG, but it would be really nice if someone could review it, especially around set-finalizer!. I'm also sure some objects are not properly freed when an error occurs. The code is in a svn repo. Thanks, Daishi ___ Chicken-users mailing list Chicken-users@nongnu.org http://lists.nongnu.org/mailman/listinfo/chicken-users
