The basic instructions for installing Mono are:

tar xzvf mono-X.XX.tar.gz; cd mono-X.XX ./configure --prefix=/usr/local; make; make install

So I've downloaded the latest version from http://download.mono-project.com/sources/mono/ and extracted it (but being that is a bz2, used the j option for tar).

The configure seems to work OK. When I run make, it plugs along for a good 40 minutes or so before this:

make[5]: Entering directory `/usr/local/src/mono-2.11.2/mcs'
make[6]: Entering directory `/usr/local/src/mono-2.11.2/mcs'
make[6]: gmcs: Command not found
make[6]: *** [build/deps/basic-profile-check.exe] Error 127
make[6]: Leaving directory `/usr/local/src/mono-2.11.2/mcs'

make[8]: *** [do-profile-check-monolite] Error 1
make[8]: Leaving directory `/usr/local/src/mono-2.11.2/mcs'
make[7]: *** [do-profile-check] Error 2

A few lines later it exits.

I'm at wits end. Endless Googles haven't really got me anywhere except a few people saying that this happens when you overwrite dll's with daily builds.

This is a brand new CentOS 6.2 install with PHP, Apache, Mysql, Webmin and now attempting Mono. I've downloaded the latest mono version (2.11.2), but the same thing happened with the last version (2.11.1).

I'm close to giving up and switching to Debian for our web server, maybe this is the way to go?

Any help appreciated. Cheers

  • I had problems installing mono 2.11.1 on CentOs 6.0. The make just stopped at a different place place each time, and the installation never ended. So I did the make folder by folder, and it worked. – Miguel Marques Oct 11 '12 at 09:22
  • @MiguelMarques: check out the instructions here: http://wiki.phonicuk.com/Installing-Mono-in-CentOS-5-x.ashx they mention bumping the ulimit -v for more virtual memory. maybe that's why you needed to 'divide-and-conquer' it? – Cpt. Senkfuss Feb 11 '14 at 14:13

Running: 

make get-monolite-latest

resolved the problem for me (as your error log suggets)

I just installed mono-2.11.3 on Centos 6.3. 2.11.3 has an updated monolight version of 104. Try getting it from this link https://wrench.mono-project.com/Wrench/ViewLane.aspx?lane_id=4&host_id=14&revision_id=12176

The updated monolight is there too, however the package was broken so I just grabbed the full mono package and installed that no problem.

I was having this same problem. The links in the answer don't work anymore.

A URL that worked for me is: http://download.mono-project.com/sources/mono/mono-2.11.3.tar.bz2
