@Tim Edwards are the install instructions for Xcircuit up-to-date on the opencircuitdesign website? I tried installing it but after running

./configure

(without any options, I am guessing it takes the default values then) and then running

make

, I am getting this missing file/directory error

Did you follow the installation instructions on the website? Under "prerequisites", it has:

sudo apt-get install build-essential tcl-dev tk-dev libx11-dev libcairo-dev

From the error message, it looks like you don't have

libx11-dev

.

yep, when I run this command, I get

0 upgraded, 0 newly installed, 0 to remove and 18 not upgraded

Apparently there is also:

sudo apt-get install libxt-dev

I thought that this was part of

libx11-dev

but apparently not.
