What is the latest version of Mono that can be run on Raspberry Pi 2? - mono

I am currently working from Mono Version 3.2.8 and am running into trouble finding any documentation on this version. I have no idea what code will run until after I get the exceptions. Either a compatibility list to what works or an idea of what version I can compile that works would be great. Any one have experience with this?

You can manually install the latest version. I was easily able to install
Mono version 4.6.2 on Raspbian.
The http://www.mono-project.com/docs/ site gives a general answer for which major libraries work. Letting you know when there isn't full compatibility but doesn't give specifics.

How to upgrade gcc compiler to latest version

I have gcc 6.3.0 and to run tensorflow 2.11.0 along with cuda 11.2, I require gcc version 9.3.1, but I just cannot find a simple and straightforward way to do that. Some people say install mysys, other sites point to sourceforge download link, while download links on mingw site point to github repos, I just don't understand how to upgrade this thing.
It would be really helpful if someone could explain it like you are explaining it to complete newbie, step by step.
Last time, I downloaded mysys2 because someone told that it will automatically upgrade gcc to latest version, mysys2 came with a python 3.10, and I was working with python 3.9, and it created a lot of issues, later I had to reset my pc. That's way I just want to know the direct way to upgrade this thing instead of upgrading other software. I also tried by downloading mingw, but the installer available on sourceforge gives gcc 6.3.0 and not the latest gcc.
And what is this cygwin which gives unix like environment, why do i require unix like environment. Even if cygwin can do it easily, I am hesitant to download cygwin, cause i don't want another repeat of tragedy that happened due to mysys2, afterall, installing a complete set of programs that i don't know anything about and will probably never use will only create additional errors.

Installing mono on raspberry without precompilation

When installing mono on raspberry, using the official way described on mono website, i get a bunch of precompilation
example:
Mono precompiling /usr/lib/mono/4.5/mcs.exe for arm...
It takes lot of time, and i also got some raspberry rebooting during the task :(
is there a way to install mono without this precompilation stage ?
According to the person in charge of Mono packaging in Microsoft, this problem is fixed in the preview (not stable) channel which brings you Mono 5.18: https://www.mono-project.com/download/preview/.

Pharo 2.0 not running on CentOS 6.6

I am trying to run my pharo2.0 application on CentoOS which was previously been installed in a mac. The original version is pharo2.0 so I need to run the same image CentoOS too, but I get an error which says this below :
/lib/libc.so.6: version `GLIBC_2.15' not found (required by xxxxx)
Should I be trying to upgrade the CentoOS and see if pharo2.0 works or port my whole application to a later version of pharo?
There is now a VM build especially for systems with an older libc version. In fact there is a build for Centos specifically (which has a slight variation in linkages from Debian), the latest version of which is permalinked here. See http://pharo.org/download#custom for more info.

Why does brew doctor say XCode 6.0.1 isn't the latest version?

Just installed Yosemite and when I run brew doctor I get:
Warning: Your Xcode (6.0.1) is outdated
Please update to Xcode 6.1.
Xcode can be updated from the App Store.
But in the AppStore it looks like XCode 6.0.1 is the latest version. What's the best way to correct this?
Tis that slight lag between 10.10 being Avail and xcode getting updated. If you read the top of brew doctor output it says
Please note that these warnings are just used to help the Homebrew maintainers
with debugging if you file an issue. If everything you use Homebrew for is
working fine: please don't worry and just ignore them. Thanks!
So if everything is working, then you should do what it suggests and ignore it. The command line tools / compilers where updated for 10.10 (software update should have picked them up for you). Are you running into any issues with compiling? or just that warning.
pulling up from the comments. Your ruby and postgresql issues are from the upgrade, but it isn't really brews fault, or that compiler error warning.
with rvm just reinstall your ruby. My main dev is done with ruby-2.1.3 so
rvm reinstall ruby-2.1.3
rebuilt ruby and all my gems. The problem is that the ssl libs (maybe others) that ruby was linked to were removed / replaced in the upgrade to 10.10. The reinstall will rebuild and relink to the newer correct libs.
postgresql is slightly different. Apparently during the upgrade a couple of empty directories in /usr/local/var/postgres get removed. No idea why.
see this SO answer for how to fix that.
`pg_tblspc` missing after installation of latest version of OS X (Yosemite or El Capitan)
also if you are use pow (http://pow.cx) you will need to upgrade it to the latest version as 10.10 removed ipfw completely and only leaves pf as the firewall. so you will need to the new version which uses pf anchors.
The above steps where all I needed to do it in order to get my dev back to working.
Looks like developer.apple.com does show an XCode 6.1 as "Available Shortly" as of Fri, Oct 17, at 10pm central time. Not yet available from the AppStore. I guess I'm just too eager for an update.
