[slime-devel] Problem loading the ASDF swank with cl-launch and sbcl-0.9.9.1
Hello, I'm experiencing a strange problem when I load the swank via ASDF and sbcl-0.9.9.1 in a cl-launch [1] session (backtrace attached). Basically, AFAIU it doesn't find the necessary *.lisp files in the ~/.cache folder. In fact, if I copy all the slime/*.lisp files into the corresponding ~/.cache folder, it works as expected. Is this a SLIME problem or a cl-launch one? I guess the latter, as without cl-launch, the swank is correctly loaded by ASDF. But I'd like to be 100% sure. Moreover, the problem seems to happen only with the swank and not with other CL software I tried, i.e. the dependencies of UCW [2] (like iterate, cl-ppcre, split-sequence and the BESE software suite [3]). Thx, bye, Gismo / Luca [1] http://www.cliki.net/cl-launch [2] http://common-lisp.net/project/ucw [3] http://common-lisp.net/project/bese

I should say that after some tests I think it's a SLIME problem. The Debian swank.asd [1] is heavily modified to bypass the load of swank-loader.lisp. And just rewriting the original swank.asd with the Debian one solves my problem :-) Now, I didn't try anything other than loading the swank by ASDF, so I don't know if with the above modification causes other problems. And I'm not a Lisp expert to completely understand the modification :-( Thx, bye, Gismo / Luca [1] http://cl-debian.alioth.debian.org/repository/pvaneynd/slime/debian/swank.as...

Ok, the root cause of the problem is that cl-launch wants to save the fasl files in a different folder than the default ~/.slime.
