Has anyone else problems with SLIME when using Lispworks on Windows (XP) and its FLI? I've run into a (reproducable but complicated) situation where SLIME simply hung while there were no problems from the LW IDE or from the command line. I'm sitting at my Linux laptop now but I can try to create a simple test case - I just wanted to check if this is a known problem.
OK, it took me a while but here it is... :) SLIME: From CVS, updated today. OS: Windows XP SP 2. Lisp: Xanalys LispWorks 4.3.7. Emacs: FSF 21.3 Take a /very/ simple C program like this one: int __declspec(dllexport) foo (int x) { return 2 * x; } Compile it with VS cl /LD /Gd /TC test.c /link /OUT:test.dll or download the DLL from <http://zappa.agharta.de/test.dll>. Now, in the LW IDE: CL-USER 1 > (fli:define-foreign-function foo ((x :int)) :result-type :int :module "c:/home/test.dll") FOO CL-USER 2 > (foo 21) 42 No problem, obviously. If I do the same in SLIME, however, SLIME hangs indefinitely after (FOO 21) and doesn't show the result. The funny thing is that LW is still there. If I now change to the inferior-lisp buffer and evaluate some arbitrary form there then the SLIME REPL buffer suddenly shows the 42 and is alive and well again. Unfortunately, I have /no/ idea what's the cause for this is but it's fully reproducible for me and currently a real show-stopper. Thanks in advance for your help, Edi.
