Can't start a new solutin in MonoDevelop

LizardGamer · 2011-12-30 05:07:25

I'm new and I'm using the 64-bit version of Arch, OK so when I go to create/start a new solution and select whatever type of project I want (e.g empty C project, empty C# project etc.) I get this error:
-----------------------------------------------------

When I reinstall the package I get the same error, and I'm not to sure what the problem is.

Moderator edit: I put [ code ] tags around your listing for you to get this mess readable.

Not sure what you are after. Moving this from "Applications & Desktop Environments" to "Programming & Scripting" for now.

I just tried MonoDevelop on my Arch 64 and hit the same problem. I can't see any solution for it at all at the moment, except I found that if you select "Other" and then any of the options such as "Blank Solution" you can at least create a project which you could then add to.

I want to be able to create projects in MonoDevelop without this error occuring

Seems that the new update of monodevelop (2.8.5-1) is the culprit... Downgrade to the previous one (2.8.4.2-1) and report the problem to the package maintainer.

Problem is that I can't downgrade the package because I usually clear the pacman cache and so it isn't there anymore

Not a good idea unless you have tested that all updates are ok

Anyway, try this URL : http://delta.archlinux.fr/pool-backup/

PS: i've reported this problem

Can't reproduce this problem. Have you selected a path for the project and a title? What I can see from this line:

  at System.IO.Path.Combine (System.String path1, System.String path2) [0x000c6] in /build/src/mono-2.10.8/mcs/class/corlib/System.IO/Path.cs:126

Try the following:
- Click on "Start new solution"
- Don't type a name in the field, just click on C# and then GTK# 2.0 Project
- now type a project name and click "Forward"

Does it work now?

EDIT:
I can reproduce yout problem if I enter a project name before I select a project type. But the steps described above are working for me.

Just tried... Same error...

Okay, the bug is reported upstream already: http://bugzilla.xamarin.com/show_bug.cgi?id=2515

Strange that it doesn't happen if I create a solution.

As mentionned in the Stackoverflow link i sent you, this bug seems appear randomly on some environments but always on others...

Yeah, I have read it. I have add a comment to their bugtracker. Hope there will be an answer soon. As long as this happen, try to downgrade to previous monodevelop version.

With a small difference this method works for me.
At step 2, before select the solution type, i don't type a name but i select a location. Without a location the same exception is raised.

Create a blank work space and then create the solution inside of that workspace. It apparently can't figure out where the default location is and needs to check if path1 is valid or not. When you create a workspace, you provide it a default location to start a solution inside of which is why this works.
