I am trying to install DDD debugger on OS X Yosemite. There is no Hombrew package for ddd anymore and I tried with downloading the source code for DDD and then running:

./configure && make

but this didn't work. I got an error saying:

creating cache ./config.cache
checking host system type... configure: error: can not guess host type; you must specify one

Is there a solution for this?

  • Look in the `configure` script and the `config.log` to see how it wants to detect the host type and why it fails. – Jester Mar 20 '15 at 16:48
  • I somehow managed to install it with a homebrew but when I try to run it I get the following message: Error: Can't find display Even after editing sshd_config (x11Forwarding yes) – Ratko Mar 20 '15 at 17:26
  • Not sure how `ssh` is involved ... anyway, check the value of the `DISPLAY` environment variable. – Jester Mar 20 '15 at 17:40
  • running echo $DISPLAY shows a blank line. – Ratko Mar 20 '15 at 17:43
  • Set it to the correct value :) If you are logging in through ssh, then it should have been set automatically, but try a value of `:10.0`. For usual local display, try `:0.0`. Don't know how that works on OSX, though. – Jester Mar 20 '15 at 17:46
  • I already tried that but it just says "Can't open display: localhost:10.0" – Ratko Mar 20 '15 at 17:54
