I've been trying over the months to use mono on Debian 7 x64 but try after try it never works. I've installed it on several different machines only to come to the same end:
mono program.exe
The assembly mscorlib.dll was not found or could not be loaded.
It should have been installed in the `/usr/local/lib/mono/4.5/mscorlib.dll' directory.
I've tried to install it on every way possible. In fact the only time I could see mono working was on a Ubuntu host but changing distro is not a option now. I dont believe this is a issue with my program because it worked on ubuntu.
This is how I proceed to install it (worked on Ubuntu, on debian never)
sudo apt-get update
sudo apt-get install libpng3 libpng3-dev libtool libtiff4 libtiff4-dev libexif12 libexif-dev libgif4 libgif-dev libpango1.0-dev libatk1.0-dev bison automake autoconf make gcc gtk-sharp2 build-essential xorg-dev libfreetype6 libfontconfig libfontconfig-dev gettext libglib2.0-dev git mono-complete libjpeg-dev
git clone git://github.com/mono/mono.git
cd mono
./autogen.sh --prefix=/usr/local
make
sudo make install
mono -V

I've searched this problem extensively and no proposed solution worked. I wonder how can anyone get mono to work on debian ?
Thanks.

Small dump question: Are you sure the application you try to run is a CLI application? – ju.kreber – 2014-04-20T10:19:58.517
Yes it is. I was able to run it on Ubuntu, and several other people seem to run it just fine. Its just this "thing" with debian that makes no sense. – Sharp – 2014-04-20T14:39:37.113
Okay. Have you checked the "missing" dll? is it there and can't be loaded for some reason or is it really missing? In this case I would try to download it manually. – ju.kreber – 2014-04-20T15:38:07.190
/usr/local/lib/mono does not exist. It makes me think it is probably somewhere else and pointing to the wrong path. And I'm not sure where I should download it from – Sharp – 2014-04-20T17:39:29.137
Mhm this is possible of course. Can't you find any mono-lib folders? For me it's under /usr/lib/. What about checking the scripts? What does this autogen.sh do? I suppose it's setting up a makefile your you.. What is then written in this makefile? Are the folders there correct? Compare the paths there and look if files have been copied correctly. – ju.kreber – 2014-04-20T20:33:00.520
It found mine under /usr/lib/ as well but no 4.5 subdir, only for 2.0, 3.5 and 4.0. I copied /usr/lib/ to /usr/local/lib/mono. After trying to run I now get a "Native stacktrace (...) Got a SIGSEGV while executing native code (...)". I suspected that the curlpit is "--prefix=/usr/local". I reinstalled using "--prefix=/usr". Same result. – Sharp – 2014-04-20T23:17:31.397
Okay. Funny thing is i got the same error yesterday. Just a question: Is the program you try to run a .NET windows application? It was the case for me. My missing mscorlib.dll should be in the 2.0 folder, i only had a 4.0 one. symlinked this one to 2.0 (just to try :D) - bunch of errors. I had to run the application through wine, with the dotnet extension. Maybe this could be the issue for you too? – ju.kreber – 2014-04-21T17:30:56.813
