Unable to compile with Monodevelop

Scripting C# & .NET
1

I am editing my scripts with Monodevelop. Until recently everything worked great, I could just press “Compile” and I saw all errors right in Monodevelop without the need to go back to Unity. Now I get some weird error message when compiling stuff:

Exception caught by the compiler while compiling:
   Block that caused the problem begin at: /Users/kork/devel/unity/minijump/Assets/Scripts/Controller/GameController.cs(16,21):

So for some odd reason it is missing Boo. Has anyone of you had that issue yet? If so, how did you fix it?

2

you likely added in JS which relies on Boo too

3

You mean I have some JavaScripts in my project - I just checked there seem to be no JavaScripts in there. Or did you mean something else?

4

Thats what I meant yes if you added a Boo or JS script anywhere in the project (including the Standard assets, pro assets, plugins folder)

5

Hmm, i checked again, there is no such thing in there. I don’t use any of the provided assets in there and there are only C# scripts… Any other reason why this could occur? Or, how I could fix it… e.g. by adding some assembly references?

6

All C# classes, but like you I do use the character controller, and maybe that pulls in something. I haven’t tried compiling my project with VS, to see if it is a mono develop thing or whatever.

In case you have this problem, add the following dll to your Monodevelop project referencelist:

/Applications/Unity/Unity.app/Contents/Frameworks/Mono.framework/Boo.Lang.dll

8

Yup that did the trick for me. Thank you :slight_smile:

I managed to solve this by installing .net framework version 4.5.
