Custom Query (1030 matches)

I have a shiny new Linux box running Ubuntu 11.10.

On installing CCL, everything appears OK when I do the rebuild-ccl step. However, in the resulting Lisp image, all math functions (i.e. log and trig functions) are no longer available: all attempts to use such give a "Can't resolve foreign symbol" error.

I've discovered that a 'workaround' is to manually load libm using open-shared-library; the load is remembered through invocations of save-application. However, I'm pretty sure this shouldn't be necessary.

I've found that this behaviour occurs with the latest versions of both CCL 1.6 and 1.7.

Terje Norderhaug reports:

Returning from backtrace fails if the Restarts dialog has been closed.

The reason is that ui-object-exit-backtrace-context attempts to #/close the (car (ccl::bt.restarts context)) even if that is a closed restarts sequence-window-controller.

See attached file.

I think this is a compiler bug.

(defun test-func ()
;;  (declare (optimize (speed 0) (safety 2)))           ;-> success
  (declare (optimize (speed 0) (safety 3)))             ;-> error
  (dotimes (i 10000)
    (remove-if-not #'(lambda (e)
		       (eql i e))
		   '(a))))

(loop for i from 1 to 50000 do
     (format t "i=~A~%" i)
     (let ((t1 (ccl:process-run-function "t1" #'test-func))
	   (t2 (ccl:process-run-function "t2" #'test-func)))
       (ccl:join-process t1)
       (ccl:join-process t2)))
