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.

My question is about whether if it would be possible to run a compiled perl 5.28.0 from source (with GCC 4.8.5 on CentOS 7) to be able to be used on RHEL 5.5 (Tikanga) where GCC version is lower and so would be the other libs like libc, glibc, etc.
Our production environment is running very old perl version (5.8.8) and due to security concerns, it is under heavy lock down, i.e. most of our servers lack make, gcc and related tools and there is no root access available to anyone
I was wondering if it would be possible to compile perl from source i.e. latest 5.28.0 with GCC 4.8.5 AND try to use this compiled version on our production servers (with GCC 4.8.2).
This will save me tonnes of headaches with slow bureaucracy and I can get going with my project with the new tools.
Have not been able to find any discussion or hint about this subject. Can anyone shed some light?
Thank you in advance.
Update after 2 days:
As it seems Perl 5.28 compiled on RHEL7 does not work on RHEL5.5. You will have to compile it on RHEL5.5 and make it relocatable for further usage on any server.
So I Downloaded the RHEL 5.5 and CentOS5.5 ISOs and ran into bootable iso related issues.
Couldn't make a suitable bootable disk for both rhel 5.5 and centos5.5.
rhel5.5 iso was a single dvd image and upon doing file rhel5.5.iso on command prompt, it showed bootable. tried unebootin, rufous iso creator, dd command and created ISOs and tried all of them one by one, but couldn't get it to show boot menu. tried FAT, NTFS FS while making boot disk. Stuck here now.
Centos5.5 iso came in 8 pieces of 600mb files. Had to create a single iso image out of it and found some online procedure to do it and made one ISO file. Got boot menu and looked like it worked. But then it got hung up on doing some sort of source media check test and couldn't proceed further. Found a fix related article that you imprint md5sum on iso and it should work but it didn't.
Just now found something on grokbase and it mentions a new technique, that could take me forward from the point of failure mentioned in point no.3 above.
Edit: static compilation bypasses the problems you are cautious about. You need to figure out whether the result is suitable for your intended purposes.
Otherwise you contend with traditional compilation like you had planned. If the libc is too different, it won't work. You could certainly just go ahead and try, then you'll know for certain.
The real solution is to set up a copy of your production environment (can be in a virtual machine) and compile stuff there.
You could try PerlApp + ActivePerl from ActiveState.com (maybe a part of PDK, Perl Development Kit). I've used it for many years. It compiles perl source and include modules (compiled modules also) into a .exe-program file on Windows and a binary executable file on Linux. There is a payed version and a free/demo version. The payed version allows for cross-compilation and more versions of Perl if I remember correctly.
You might run into trouble with differing versions of glibc/libc on dev vs prod computer, so try to use PerlApp on a CentOS 5.5 Linux (free) for compilation. CentOS5.5 resembles RHEL5.5 enough for most projects. Good luck.
Try perlbrew (is an admin-free perl installation management tool)
I'm trying to configure CLion with Cygwin, but I'm having trouble with CMake. The program says that the bundled version doesn't work in that environment and that the CMake from Cygwin is outdated (needs a newer version). However, I tried installing an independant CMake but then the program says it isn't compatible with Cygwin. How do I fix this?

I'm teaching a C++ programming class this semester. All of my students were able to successfully install/configure CLion without too much trouble. Most of them are on Windows boxes, Win7 and Win10.
In my instructions, I referred them to this video, which was the best I could find: https://www.youtube.com/watch?v=i2h_976SpV0
Some of the students were missing the debugger the first time they tried this. In the cygwin installer, the number of check boxes is enormous and many of the names are remarkably similar. When we went back through and re-ran the installer, in each case we were able to find a place where they had checked the wrong box.
So my recommendation would be re-run your cygwin installation after watching the video once through. Then go back to the frame in the video where he shows all his checked install options and very carefully compare your checked boxes against the presenter's.
Good luck!
I'm trying to install/update my clang from Apple clang version 1.7 (tags/Apple/clang-77) (based on LLVM 2.9svn) to clang version 3.3. I've downloaded the pre-compiled binaries into usr/bin/, as suggested by other posts (How can I update clang to 3.3 on Mac OS X 10.6).
The point of this installation/update is to be able to use C++ code (not written by me, and written for a newer machine OS 10.8.x) on my mac. I would preferentially use Xcode to update this, but unfortunately, Apple has not made the necessary version of Xcode available for free without a developer's subscription.
I've edited my PATH and LD_LIBRARY_PATH to include clang3.3/bin/ and clang3.3/lib, but I get an "Illegal Instruction" error and it's not clear to me why this is.
What I'd really like is to try the whole process again from the beginning with a step-by-step outline of the process, like is seen here (How to install clang pre-built binaries ubuntu 12.04), except for Mac OSX system, not Ubuntu.
I realize there are some previous threads that ask almost the same question, but I am asking specifically for these versions (and from a standpoint that includes very little experience installing via terminal/understanding pathways/etc.).
Thanks for any help.
I have been using RapidSVN on a Linux machine for the past few years - it has become an excellent tool for managing my source.
Yesterday my trusty Linux laptop had a couple of strokes so I decided it was time to replace it. Today I went out and purchased a new Mac Book Pro with the flashy display and solid state drives.
Then I went hunting for an SVN tool to run on Mac. I found that RapidSVN will run on a Mac as it was developed using wxWidgets (cross platform windowing).
So, I needed to install wxWidgets, however this doesn't come as an executable so I had to download the tar ball. To compile I realised I don't have a compiler installed yet... so, install Xcode 4.4, then learn that doesn't install a compiler either... find the Xcode preference to install the command line tools (compiler).
So, now I have Xcode installed, a gcc compiler, and tracking back up it comes to wxWidgets. It takes a little working out but I manage to extract the files into a directory in my home folder, (following instructions of course), and from the 'build' folder I run the ../configure command (which seems to work) and then the 'make' command which fails:
In file included from ../include/wx/mac/private.h:4,
from ../src/common/dynlib.cpp:48:
../include/wx/mac/carbon/private.h:1459: error: ‘Cursor’ does not name a type
../include/wx/mac/carbon/private.h:1488: error: ‘ClassicCursor’ does not name a type
make: *** [baselib_dynlib.o] Error 1
So I go hunting for a solution only to find this bug: http://trac.wxwidgets.org/ticket/14536 which unfortunately indicates this is not going to be fixed.

A dismal day in the land of computers. I am now stuck for the next 5-6 years on a computer that will never be able to compile anything using wxWidgets - I rather feel like taking it back to Apple and getting my money back.
So where to from here? Is there a binary version of wxWidgets available? Is there a binary version of RapidSVN available? Should I downgrade to OSX 10.x something less than I am currently on? Should I upgrade to unstable wxWidgets?
This is an interesting but not very understandable read. What exactly are you trying to achieve? If you're looking to use the best available version of wxWidgets under OS X, get 2.9.4 or the current svn version and build it using the Xcode version you have already with Cocoa support. If you absolutely need to continue to use Carbon (why?), either install Xcode 3, available from Apple, or get 10.6 (or 10.5) SDK in some other way and pass it as the SDK to use to configure using --with-macosx-sdk option as explained in the documentation.
VZ is right. If you need to use wxWidgets 2.8 on OS X (and there are legitimate reasons for needing to do so), get the 10.6 SDK. Copy it alongside the already installed 10.7 and/or 10.8 , and select it in the project/target's build settings.
From here I have given up trying to compile anything on my current OSX. I am not going to downgrade or install multiple versions of different libraries in order to satisfy the lack of support for the latest current stable versions.
From here I will download and install binaries only.
I have Mac OSX Lion and just did this:
brew install wxmac
and was able to get through the install with no issues.
I have a bit of a problem. I need to use the strace utility to figure out why a command is crashing on an older Linux system. Unfortunately, I don't have strace nor do I have gcc/binutils on that system.
I tried building the app statically on a current Debian system, but calls to getpwnam require a dynamic load of the version of libc that was used at compile time. That would be fine, but being that the utilities on the older system were all built using an ancient version of libc, putting a newer libc on that system breaks everything else.
Short of downloading and installing an old distribution of Linux and then doing the build, is there an easier way around this problem? The original distribution on this system is currently unknown and the more I research it, it's getting to seem like a huge chicken vs egg problem. Any tips would be much appreciated.
Using an outdated Linux system is never wise... can it be upgraded? If not, why not? What is failing, and how? Any chance of updating that?
There should be a file named /etc/release or similar, that should give you an idea of the distribution and version. Or uname -a might give a clue on the distribution. If it doesn't work, try to see if commands like rpm, apt-get, or one of the other package management commands are available, that will narrow down the distribution. A Google search for some of the installed packages with versions might help narrow down the version of the distribution.
Knowing distribution and version you may be able to get strace (and perhaps other needed packages). Many distributions keep archival versions (at least of the original installation media for old versions) around.
