Doxygen-latex dependency should be optional

Confirm on Ubuntu 11.10 Beta 1:

$ apt-get install -s doxygen
NOTE: This is only a simulation!
      apt-get needs root privileges for real execution.
      Keep also in mind that locking is deactivated,
      so don't depend on the relevance to the real current situation!

So to install doxygen, I must download 370 MB and I need 571 MB of free space on my hard disk.

I'm not sure quite how this is okay dependency-wise but it seems you can install the "doxygen" package alone with Synaptic:

1. Open Synaptic Package Manager (assuming you have installed this)
2. Mark "doxygen" (marking its many unnecessary Latex dependants)
3. Go to "Custom Filters", "Marked Changes"
4. Select all the packages except "doxygen", right-click and "Unmark"
5. Click "Apply"

Will report back if I hit any issues but initial tests show it works. Haven't figured out how to do the same with apt-get but perhaps someone else can jump in.

Workaround: sudo apt-get --no-install-recommends install doxygen

apt-get may still decide to download the "recommended" 417MB during Ubuntu upgrade ;)

I think most people create HTML docs, so the latex stuff should not be installed automatically.

Aww come on its frigging 2013 !

1G for doxygen ??

I'm using some custom software that heavily relies on the latest version of LaTeX, which I did not install from the standard repos. Thus I have installed LaTeX (the TeX Live flavour) into /usr/local/texlive/2012/.

Installing LaTeX twice on the same machine is definitely a waste of space. If this dependency can be removed, that would be superb.

I use this Workaround: sudo apt-get --no-install-recommends install doxygen
and it works under Ubuntu 12.04.
