[Sbcl-devel] shared library reload on restart

[Robert B. <rob...@gm...>]

Today, I used SBCL to compile and load matlisp.  Matlisp requires a shared
library that's loaded as follows:

  (sb-alien:load-shared-object "matlisp:lib;libmatlisp.so")

After Matlisp is loaded up, one dumps SBCL's state with a function that
calls SB-EXT:SAVE-LISP-AND-DIE.  Before dumping SBCL, however, I changed th=
e
logical pathname translation for MATLISP, hopeful that SBCL would, upon
restart, load the Matlisp library from the new location.  Unfortunately for
me, it looks like SBCL caches the Unix file name associated with the shared
object, not the logical pathname, so that when SBCL is run again, it tries
to load the library from the exact same spot, even though MATLISP now point=
s
elsewhere.

Does this sound like the Right Thing or should SBCL cache the argument of
LOAD-SHARED-LIBRARY instead of the result of calling SB-INT:UNIX-PATHNAME o=
n
the argument?
