Debugging Lisp & SLIME, error "Cannot find source location"

开发者_JS百科I am wrote the code with bugs.

Example:

(print (/ 1 0))

I am trying compile with C-c C-c. And catch the error with stack frame.

I want see line in the code where an error occured. Clicked 'v' on line in stack frame and catched error.

Error: Cannot find source location for: #<COMPILED-CODE-LOCATION 
(SB-C::VARARGS-ENTRY /)>  

How can I go to the line in my code?

As you can see from the error, the line you want to jump to, is somewhere in package SB-C, which is part of SBCL. If you don't have SBCL sources (you've installed a binary or deleted them), you should get them (relevant to your current SBCL version) and then link them up in .sbclrc like this (according to http://www.cliki.net/SLIME%20Features):

(setf (logical-pathname-translations "SYS") 
      '(("SYS:SRC;**;*.*.*" #P"/opt/sbcl/src/**/*.*")
        ("SYS:CONTRIB;**;*.*.*" #P"/opt/sbcl/contrib/**/*.*")))

Or just compile SBCL from source and it will know, where they are.

Do you have (proclaim '(optimize debug)) above that line somewhere? This function will ensure that your system has all the debugging data it can get.
