How can I install the latest release of Mono in Ubuntu Saucy?

In order to develop in a free OS, I need to setup Mono (that now supports .NET 4.5). This is what I did:

  1. Download and uncompress mono-mono-3.2.5
  2. Run ./autogen.sh --prefix=/usr/local (finished ok)
  3. Run make, but it exit with error checking dependencies:


mkdir -p -- build/deps
make[6]: gmcs: Command not found
make[6]: *** [build/deps/basic-profile-check.exe] Error 127
*** The compiler 'gmcs' doesn't appear to be usable.
*** You need Mono version 2.4 or better installed to build MCS
*** Check mono README for information on how to bootstrap a Mono installation.
make[5]: *** [do-profile-check] Error 1
make[4]: *** [profile-do--basic--all] Error 2
make[3]: *** [profiles-do--all] Error 2
make[2]: *** [all-local] Error 2
make[2]: Leaving directory `/home/hogar/Software/mono-mono-3.2.5/runtime'
make[1]: *** [all-recursive] Error 1
make[1]: Leaving directory `/home/hogar/Software/mono-mono-3.2.5'
make: *** [all] Error 2

But to install mono-gmcs, Ubuntu will also install mono-runtime v2.10.8.1-5ubuntu2. And that is exactly what I'm trying to not install, an old version of mono.

This is confusing me, what should I do?


It needed to have another instance of mono already installed, so apt-get install mono-gmcs did the job. Then, a new error appeared, and the only solution seemed to be using the GitHub package:

git clone git://github.com/mono/mono.git
cd mono
./autogen.sh --prefix=/usr/local
make install

Now I have installed the latest version of mono.

NOTE: now I am not able to run any mono program, e.g. monodevelop. I couldn't find the solution to the exception, so now I'm downgrading mono to an old & compatible version.

PS: If you find the solution, please leave a comment :)
