How to install mono?

Has anyone ever successfully install this?

I'm trying to install it but pulling my hair out.

It keeps saying it wants this libexif.so.9 file yet it EXISTS. It refuses to go further. Isin't yum suppose to take care of that? I don't understand why it's giving met this trouble.

If I try to install libgdiplus I get the same error. Whats going on? I thought yum was supose to automatically resolve dependencies.

Try reinstalling the package which owns libexif.so.9.

Or, from here: http://www.centos.org/modules/newbb/...11944&forum=38

"Just make sure that the extras repository is enabled and do a 'yum install mono-core'. "

I tried all of that, no go. Though I'm using FC7, would I have better luck with centOS?

A bit strange it didn't install a dependacy, maybe the mono installer is out of shift for FC7 since FCs tend to come out like every 6 months. might be worth a try on a newer version of FC first if you are unable to install the dependancies via yum. CentOS is great for servers but not so great for desktops, can still work for desktops but setting up simple things like mp3 codecs are quite alot harder on CentOS for example, it's more geared towards being a server since it's a direct RHEL clone.

Trying FC9, the one I downloaded was actually made for FC9. This will be a server.

Just tried with CentOS 5.2 x86. Still no go, exact same error.

Code:

[root@destard runuo]# yum install mono

I even tried "yum install libexif" and "yum instal libexif-devel" which both install, but its still telling me they don't exist.

I also checked this post: http://www.centos.org/modules/newbb/...11944&forum=38

Tried everything there, no go. I'm really at loss. IS there another distro I could try? I'm open to any distro as this box will be pretty much dedicated to running a .net application.

Or should I just rewrite the application in C++? Would that be easier? (about 500k lines of code or so)

Ok got it working, I was actually suppose to NOT use the mono provided repository.

Not sure if this is mono specific or specific to the app I'm compiling but I get this error:

Could someone point me in right direction as to where I should look to try and debug this? No line errors or anything make it rather hard.

This would probably be better posted at the mono forums but their forums are broken. Can't register there for some reason. Keeps saying the auth code is wrong even though I type it in exactly.
