How to get Mono?

There are at least three different ways for getting Mono installed on your Cubietruck. All of them have their pros and cons:

Install it from the debian package repository

+ very easy to handle
+ fast installation
+ works with LogView Studio (LvCmd)

- mostly an old Mono release
- WinForms applications produce errors with some components (like a Textbox)

Compile it from a TAR package

+ works with LogView Studio (LvCmd)
+ sometimes the GIT version has compilation errors which the TAR version don't have

o mostly newer than the Raspbian package but older than the GIT version

- takes a long time to compile
- needs some extra packages for compiling
- WinForms applications produce errors with some components (like a Textbox)

Compile it from the GIT repository

+ works with LogView Studio
+ WinForms applications work from Mono 3.8.1
+ always the newest release

- takes a long time to compile
- needs some extra packages for compiling

Which method is the best?

For the Cubietruck the best choice is to to compile it from GIT.

Note
If the TAR package gets to a 3.8 version this would also be Ok. At the moment of writing this text there is only a 3.6.0 version available.

AOT

Ahead of Time Compilation or AOT is a feature of the Mono runtime code generator.
We don't need it to run LogView Studio and in some cases it results in compilation problems on ARM. So we just disable it.
