Error division-by-zero in first example from tutorial #6
Comments

Hello Artyom, thank you very much for your interest in the Lisp binding to GTK+. If I see it correctly, you are using a 64-bit Ubuntu 12.04. I am working with a 32-bit Ubuntu 12.04. You can use the library function cl-cffi-gtk-build-info to get more information about the installation. On my notebook I get:
cl-cffi-gtk version: 0.0.0 At this time I have no idea what is going wrong. It seems to me that the error originates from the library Bordeaux Threads, which might not work correctly on a 64-bit system. But perhaps I am completely wrong. Remark: I am working now about 6 month on the cl-cffi-gtk library. At this moment I update the complete library to GTK+ 3.4. To get the implementation complete I have to implement even more functionality of the libraries Cairo, Pango and GIO. All examples of the tutorial work correctly with GTK+ 3.4 on my Ubuntu 12.04 32 bit with SBCL 1.0.56. Every help to solve the reported problem is appreciated. Dieter Kaiser |

Today I'm going to try it on my second Ubuntu 12.04 x86. |

Same problem here. Linux ubuntu 3.2.0-23-generic-pae #36-Ubuntu SMP Tue Apr 10 22:19:09 UTC 2012 i686 i686 i386 GNU/Linux cl-cffi-gtk version: 0.0.0 Should I try with latest bordeaux-threads? |

I see the same, but randomly. Sometimes it works, sometimes I get the same error and backtrace. cl-cffi-gtk version: 1.0.0 |

The problem seems to be in the library Bordeaux Threads. I can not reproduce the issue. I use the library version 0.8.2. I have not done an asdf-install, but I have downloaded and installed the release bordeaux-threads-0.8.2.tar.gz which is available from http://common-lisp.net/project/bordeaux-threads/releases/ . With this version of bordeaux threads, SBCL 1.0.57 and earlier versions of SBCL I never had a problem. Perhaps I can get your version of Bordeaux Threads to reproduce the issue on my system. This is the build info on my system. I am working with SBCL 1.0.57 on an Ubuntu Linux 1.0.4 (32bit). You get the build info with the command (cl-cffi-gtk-build-info). cl-cffi-gtk version: 1.0.0 Dieter Kaiser |

I have mine installed via quicliksp, but I did a diff vs the tar.gz release and it's identical (0.8.2). I just realised I should mention that I am testing in slime, which spawns some additional threads itself. Simply running sbcl --load tutorial.lisp with some sample code does not appear to trigger the issue (ran it 10 times, happens more often when in slime). |
Empty window appears but then error signalled.
