I am trying to move an application from Windows -> Linux and the graphics part seems to be the most difficult. I hope that ltk can help me along. Under ubuntu 8.10 and SBCL 1.0.23 I have downloaded ltk-0.91.tgz and extracted it into its own directory. SBCL happily compiled ltk.lisp and ltk.fasl loaded too. When I tried to run (ltktest) SBCL became unhappy: Couldn't write to #<SB-SYS:FD-STREAM for "descriptor 6" {B98E79}>: Broken pipe. Perhaps I have put ltk in the wrong place ? Perhaps there is something which I have failed to set up correctly. I see from the troubleshooting file that some web connections/applications can cause difficulty. I am running firefox - from which I retrieve ltk! Any and all advice/comments gratefully received Cheers /Greg Bennett
