monodevelop should depend on xterm

[Csipak Attila]

Steps to reproduce:
1. Lubuntu 12.04 clean install (it may work on an older install too, but if it doesn't, try a clean installation).
2. Install MonoDevelop from the Lubuntu Software Center.
3. Start MonoDevelop.
4. Start a new solution and a new C# console project within it.
5. MonoDevelop autogenerates a Hello World! program for you.
6. Try to run or debug (Ctrl+F5 or F5) the unmodified source code and experience the error:

File name has not been set

It seems that monodevelop uses xterm to run console projects, but xterm is not a dependency for monodevelop. Since xterm is not part of a default Lubuntu installation, MonoDevelop will throw an error at step 6.

The workaround is to install xterm manually via apt-get, synaptic, or Software Center.

I'd guess the bug can also be reproduced by simply uninstalling xterm from a working Ubuntu 12.04 installation (I didn't try this so far though).

This problem has been around on other distros & platforms, see this forum thread for an example: http://mono.1490590.n4.nabble.com/File-name-has-not-been-set-td1510697.html

AFAIK this is a simple packaging problem.

monodevelop already depends on xterm. Here it's the debian/control:

Paolo, I checked the package dependencies again and it looks like you are right. I wonder what happened last time, when I posted the bug?
Well, if no one else confirmed this bug then most likely it's a one in a lifetime problem or bears no importance. So I will just mark it Invalid.

Same problem using Monodevelop 3.0.3.2 in KUbuntu 13.10 "saucy salamander" beta 2
xterm is not included as monodevelop dependence

[Darren (darren-dcook)]

Had the same problem. Suspicious, I then completely purged mono and monodevelop from my system and did:

   apt-get install mono-complete monodevelop monodevelop-nunit monodevelop-debugger-gdb

But, still, when trying to run any program from within monodevelop I get "cannot execute" because "filename has not been set".

I then do `apt-get install xterm`, close monodevelop, re-open, and now it works.

Other sources to confirm this:

   http://stackoverflow.com/a/22060671/841830
   http://unix.stackexchange.com/a/126051/52393 (but I didn't need to do the extra steps there, just installing xterm was enough)

Reopened, since two other users are affected.

I just installed monodevelop on a fresh install of lubuntu 16.10. I could only run my program once i seperately installed XTerm... So i guess this problem ist still there!
