I installed QCad on Crunchbang Linux, Waldorf using synaptic. Now when I check in terminal, it is installed

$ sudo apt-get install qcad
Reading package lists... Done
Building dependency tree

qcad is already the newest version.
0 upgraded, 0 newly installed, 0 to remove and 256 not upgraded.

But when I try to run it, this is what I get:

$ qcad
bash: qcad: command not found

Any thoughts what the problem might be?

Debian replaced QCad by LibreCAD, a fork that's fully free software. The qcad package in Debian wheezy (which Crunchbang is based on — it's getting really old) is a basically empty package that depends on librecad, it's just there to facilitate upgrades. The real software is in the librecad package and it's called librecad.

You can list the files in the qcad package with

dpkg -L qcad

You'll see that there are very few files, and /usr/share/doc/qcad/NEWS.Debian.gz will tell you what's going on.

The information is also present in the description of the qcad package which you can see with

dpkg -s qcad

or apt-cache show qcad (which works even if qcad isn't installed).

  • I see. Good point, thanks for explaining.
