[slime-devel] problems with kawa + slime

Tue Dec 9 07:30:29 UTC 2008

Hi,

It's great to see some support for kawa in slime.. I wanted to give it
a go today but ran in a few showstoppers. With the latest kawa
compiler I ran into an error which might be a compiler bug, when
issuing the compile command:
(compile-file "swank-kawa.scm" "swank-kawa") I get a stack trace:

java.lang.Error: popType called with empty stack

After going back a few versions (to revision 6150) the swank-kawa
compiles but I get the following error when starting slime in emacs:

Any ideas how to fix these? (Running on OS X Leopard, Java 1.6.0_07)
