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.

I have been following this guide to install gnuradio 3.8 onto my Ubuntu 22.04.1 LTS, but I missed the instruction where it said "Ensure the "gitbranch" is maint-3.8", and mine said maint-3.10. After trying to install gr-iqbal, it gave me an error. For whatever reason, I thought that simply deleting the directory it was built in would let me reinstall it. It didn't.
I have tried using pybombs install gnuradio which gives me CMake Error: The source directory "/home/aboigoe/sdr/src/gnuradio" does not appear to contain CMakeLists.txt.
I have tried using pybombs rebuild gnuradio, but that obtains Package gnuradio is not installed into current prefix. Aborting.
To fix that, I tried using pybombs fetch gnuradio, which runs fine, but doesn't fix the previous error.
Finally, I tried pybombs remove gnuradio, but it says Package gnuradio is not installed. Aborting.
So you're working with pybombs! That makes this particular task easier: just delete the whole prefix, and start anew. The main thing you needed to build in that prefix was GNU Radio, and you built 3.10, and wanted 3.8, so that's a complete rebuild, anyways.
I assume you're following that guide (which comes, kind of, out of nowhere – GNU Radio has installation guides on their wiki, https://wiki.gnuradio.org) because you want exactly GNU Radio 3.8, with gr-osmosdr and gr-iqbal.
If you just want a working GNU Radio that can talk to your SDR hardware, um, don't follow random guides from the internet :) Instead, your whole problem boils down to a simple
sudo apt install gnuradio
and that's it – GNU Radio 3.10, as Ubuntu 22.04 ships it, contains gr-soapy, and Ubuntu's apt will install many available hardware drivers (for RTL-SDR, hackrf, mirisdr, bladerf, audio-interfaced hardware, red pitaya,…) without any need to do anything yourself. It just works.
The thing that will be different is that the blocks to inteface with your hardware will not reside under the "osmosd" category in your GRC, but in "Soapy", but I guess you'll deal with that rather than going through the rather convoluted way of installing an old (and not updated anymore) version of GNU Radio, to include an old (and not updated anymore) version of gr-osmosdr :)
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.
I'm trying to understand why the easy_install of pyicu works and pip install doesn't (see below). also trying to understand "What is the difference between a PyPi project with a universal wheel and one without?" Will installs be "easier?". If so, will this merge request solve the problem of polyglot not installing on an Anaconda machine?
Need help/advice/solutions on how to best resolve python project install issue that is tied to underlying dependencies. I have two local fixes in GitHub Gists but would like to know the best way to have this fix "out there" so people like me can find it. What is the normal Python Community approach? The problem centers around three projects:
polyglot - a python multilingual NLP toolkit
pyicu - Python extension wrapping IBM's International Components for Unicode C++ library (ICU).
pycld2 - CLD (Compact Language Detection) library as maintained by Dick Sites
The goal:
Install polyglot on a MacOSX computer running Python Anaconda Distribution
Make the fix I found available to everyone; lots of issues published about the problem.
Here's the error trace:
The Problem (Lots of them):
Core polyglot dependency, pyicu, does not properly install when you use pip install. Discovered you must use easy_install for it build properly and work on MacOSX. If you don't use the easy_install, you get:
polyglot requires icu 54.1.1 to run in Anaconda, but...
Homebrew, the MacOSX tool to install icu, only installs version 58.1. That version is too new. Old stackoverflows advise brew install icu4c to fix problem, but Homebrew evolution makes that advice obsolete now.
pyicu does not have a universal wheel; but I created a merge request to add one to pyicu. Only way to fix this is with this channel's icu, https://anaconda.org/ccordoba12/icu. conda install icu will not work, but that's the normal conda way of doing things.
*pycld2 - CLD (Compact Language Detection) becomes a problem because after I build the wheel file locally, have to download the project and run setup.py install locally. There has to be a better way to do this right?
What I've Done to Solve the problem (should I do more, what should I do next?)
Created two Gists that can successfully install polyglot on a Mac running Anaconda for Python 2.7 or Python 3.5
Python 2.7 fix
Python 3.5 fix
created the merge request for pyicu
Both Gist fixes work. But, is this error in install tied to the wheel? If I installed pyicu with easy_install, the install works. But, with pip, it doesn't?
What are the steps to take in the Python community to fix it so people can find the solution or just pip install with no problems?
I did a test, and if the wheel file is built, the pip works with no issues.
I tried to install mono and monodevelop on centOS 6.3.
After many hours I was able to install mono but failed with monodevelop.
I'm really astonished how difficult and time consuming it is, to get a recent mono/monodevelop version on linux installed.
Is there nobody willing to write and maintain an install/compile tutorial to get the most recent mono/monodevelop/monodata/ASP.NET MVC/... version on the major linux distributions (Centos, Ubuntu, Suse, Debian) installed?
I think many people developing on Windows (with limited linux knowledge) would like to start using mono, if the boarding hurdle would be somehow lower.
It may be the most important to make Mono more used and more visible.
Please, write a tested tutorial (script) for compiling mono/monodevelop.
Thank you!
I have created a project on Open Build Service, which produces builds of the latest MonoDevelop 4.0.10 for Debian, Ubuntu, CentOS, and Fedora.
see https://build.opensuse.org/project/show/home:tpokorra:mono
For installation instructions with apt-get or yum, see:
http://software.opensuse.org/download/package?project=home:tpokorra:mono&package=monodevelop-opt
I hope this will increase the usage of MonoDevelop on Linux Desktop environments.
Monodevelop 4.
If you use any *buntu. Check this.
"You can open up the terminal and install it via the following:
1. sudo add-apt-repository ppa:keks9n/monodevelop-latest
2. sudo apt-get update
3. sudo apt-get install monodevelop-latest"

Xamarin should be doing a better job at publishing the linux packages in a one-click manner. I don't care what linux distro (SuSE, RHEL, CentOS, Ubuntu etc) - just pick any one as the supported one and publish for it. It seemed that it used to be SuSE but even that has old packages as seen within Zypper/YaST.
Update Mono framework
Having said that, to update the Mono framework itself, without letting go of the package managers try this. This will work as long as the project dutifully publishes the RPMs. You don't want to build from source since it's a more fickle process and the setup distracts from your real objective (i.e. develop).
Obviously, please replace the URL below to what will be latest by the time you're reading this.
mkdir mono-rpms
cd mono-rpms
wget --reject "index.html*" -nd -r -e robots=off --no-parent http://download.mono-project.com/archive/3.2.3/linux/x64/
sudo zypper install *rpm
Update MonoDevelop (the IDE)
Timotheus Pokorra's answer indicates he's filling in some of the usability void left by Xamarin (Thanks Timotheus!!). You can install MonoDevelop via
http://software.opensuse.org/download/package?project=home:tpokorra:mono&package=monodevelop-opt
Note that on SuSE I get the error
Problem: nothing provides liberation-mono-fonts needed by mono-libgdiplus-opt-3.0.12-7.1.x86_64
Solution 1: do not install monodevelop-opt-4.0.12-5.2.x86_64
Solution 2: break mono-libgdiplus-opt-3.0.12-7.1.x86_64 by ignoring some of its dependencies
I (very reluctantly) selected to break the dependency. Note that I already had liberation-fonts (via sudo zypper install liberation-fonts). I don't know if its the same/different as liberation-mono-fonts. Anyway, hope Timotheus fixes it when he has a moment.
I'm not sure if you've already seen this, but this may help:
http://www.mono-project.com/Parallel_Mono_Environments
The most common problem that new developers have when coming to Linux from systems like Windows is not properly setting up their environment variables and so when they do the standard ./configure && make && make install routine, when it involves a number of source packages (like Mono does), any package that depends on the core package won't pick up the correct location for that base package.
Your question really doesn't explain what parts you found confusing or difficult so it's hard to address those issues.
For people unfamiliar with setting up Linux systems, it may be easier if you just go with a system like Ubuntu which has fairly recent pre-built packages (although not the latest - I don't think any Linux system keeps up with Mono releases) rather than wrestling with the learning curve of how to build everything yourself.
It is confirmed that in the near future Xamarin will support Linux and provide binaries (mono and mainline applications) for Debian and Centos derivatives, and their are already packages for Debian and Centos derivatives for technical preview. So cheers and no more pain of compiling and even parallel mono installaions.It can not get more easy than this. Check here
I have:
Ubuntu 8.04
python 2.5.2 installed on this Ubuntu
matplotlib 0.92.0 installed
I want to upgrade to (atleast) matplotlib 0.99
so that I can do 3d plotting.
The synaptic package (also the command line apt-get)
tells me that whatever I have is the latest matplotlib (which is not true).
How can I install matplotlib 0.99 or matplotlib 1.0.1 ?
You have the latest available package version for your operating system. Given that Ubuntu is at version 11 now and you are using 8.04, the version difference in the matplotlib package might not come as very surprising.
As for installing the newest version, I'd suggest reading:
http://matplotlib.sourceforge.net/faq/installing_faq.html
...if all fails, you can always install from source.
Note that support for Desktop versions of 8.04 LTS is due to expire shortly -- if this is a desktop machine, perhaps the easiest answer is to upgrade to 10.04 LTS, 10.10, or the very-soon-upcoming 11.04 release (or whatever they'll call the next release). Maybe not "the easiest answer", but an answer that includes security updates for Mozilla, Adobe Flash, the Kernel, and so forth.
Many newer versions of packages are supported via the Ubuntu Backports facility, but I didn't spot python-matplotlib in the list of available packages. Perhaps they would provide it if you asked nicely, perhaps it would be too much work.
You can always try installing newer versions from newer releases, but newer versions of python and libraries might introduce worse problems. (But probably will work fine.) See the apt_preferences(5) manpage for details on how to configure multiple APT sources and select some specific packages from a newer distribution (pinning), and rely on the older distribution for all the other packages.
Jim's answer of building the version you need from source is probably your best second option, if installing a newer version of the distribution is too daunting / otherwise impossible at this point.
