Using SLIME on windows revisited

A little over a year ago I posted about problems with using sbcl with  
SLIME on windows. I did get some help, but was still not able to get  
our system working then, so I gave up and have just recently turned to  
it.

The problem seems to be with sb-bsd-sockets and save-lisp-and-die. I  
give a transcript below that loads sb-bsd-sockets and everything is  
working fine, but after save-lisp-and-die and running the saved  
executable, get-protocol-by-name now fails. I checked that this works  
on Mac OS X. It also works if sb-bsd-sockets is loaded after  
restarting a saved executable, but we really want to deliver  
executables that don't have to load anything.

Is there something that needs to be reinitialized after starting a  
saved executable? Any suggestions?

Thanks,

Just a guess - try funcalling sockint::*wsa-startup-call* when  
starting your saved core.  I don't see this being called anywhere in  
sb-bsd-sockets itself, but calling WSAStartup is necessary for using  
sockets on win32 iianm.

Cheers,

Rudi

Re: Using SLIME on windows revisited

Thanks Rudi,
That was close, and I have it working now. In win32-sockets.lisp I  
changed

(defvar *wsa-startup-call*
   (wsa-startup (make-wsa-version 2 2)))

to

(defun wsa-init ()
   (wsa-startup (make-wsa-version 2 2)))

(push 'swa-init sb-ext:*init-hooks*)

(defvar *wsa-startup-call*
   (wsa-init))

foreign function from a static library

Hi,

  I'm wondering whether SBCL has provision for calling
a foreign function from a static library archive.
Thanks in advance,

No. IIRC that functionality existed in CMUCL, but was removed due to
maintainability concerns.

Why not just compile the static archive into a dynamic library?

For libraries whose source files I have access to, yes that is what I do.
On the system I'm using there are some libraries that are installed
only in static archive form.  I wish all systems where like solaris.

I *think* that with sufficient linker magic you should be able to
produce a .so that exports all symbols from your .a. I think.

How can this work if the code in the library was not compiled -fPIC?
