How to Install Mono on CentOS 5

I am a .NET developer, but for the need of my job, I am also familiar with CentOS 5 and OpenVZ. I have installed Mono on my Windows XP environment before, and want to have a try Mono under CentOS 5.
This time I use a CentOS 5.2 VPS(a clean VPS I just created)to install the last version Mono(v2.4.2.3).
First of all, I tried the easiest way to install Mono,
#yum groupinstall Mono
But I noticed the version of Mono I installed is 1.2.4, seems that the lastversion of mono ( is not in the CentOS package repositories.
Then I tried to find the last version distribution from Mono Home page and google, but no result, So I had to download the source code and compile it all by my self.
After some attempts, I got the following steps to compile and install the last version Mono on my CentOS 5.2 VPS host,
1.prepare the compile environment,
# yum install gcc bison pkgconfig glib2-devel gettext make

2.Go to this page and download the last version Mono(in my case, mono-,

3.Extract the downloaded file,
# tar jxvf mono-

4.Change to the newly created directory,
# cd mono-

5.I put my built packages in /opt so, run the following command to build mono,
# ./configure –prefix=/opt/mono; make; make install

6.Update ~/.bash_profile,

#echo export PKG_CONFIG_PATH=/opt/mono/lib/pkgconfig:$PKG_CONFIG_PATH>>~/.bash_profile
#echo export PATH=/opt/mono/bin:$PATH>>~/.bash_profile
#source ~/.bash_profile

7. Test it,
#mono -V
and I got the output:

Mono JIT compiler version (tarball Thu Oct 22 06:42:24 MSD 2009)

TLS: __thread
GC: Included Boehm (with typed GC)
SIGSEGV: altstack

Great, I got it.
I think I’d better put all script I used in one place,

mkdir ~/software
yum install gcc bison pkgconfig glib2-devel gettext make
tar jxvf mono-
cd mono-
./configure –prefix=/opt/mono; make; make install
echo export PKG_CONFIG_PATH=/opt/mono/lib/pkgconfig:$PKG_CONFIG_PATH>>~/.bash_profile
echo export PATH=/opt/mono/bin:$PATH>>~/.bash_profile
source ~/.bash_profile
mono -V
cd ..
rm -rf mono-

  1. Thank you for useful information. My question is how can you now execute C# exe file with user interface that was before prepared in Windows XP? I have problem to do this in CentOS, however I do it in Ubuntu in simple way, exactly as it is written in the Mono instruction.
    Thank you
