I previously compiled webkit-qt on kubuntu 11.10 from their svn sources. I remember that it worked well with the kubuntu konqueror and rekonq packages, while their webkit packages are useless (very unstable). I had to export QTDIR and to pick an older svn revision because the current one didn't compile. Now I have to reinstall webkit but I do not remember which svn revision I used. Which of their svn revisions compile with --qt?
The current svn revision (114036) of webkit compiles on ubuntu 11.10 with kde 4.8 and all current updates from the backport ppa.
It is sufficient to checkout the Source and Tools subdirectories (the overall repository is very large)
Compilation is with
./Tools/Scripts/build-webkit --qt
sudo make install
Segmentation faults may be due to lack of RAM. Possibly the option --no-svg to drop the support can save memory compilation time.
Note that this will install in the default directories replacing present installations. On my system rekonq and konqueror run well with (while the outdated ubuntu webkit packages cause frequent crashes).

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.
sudo apt install capnproto
This installs v0.7.0 in my ubuntu 20.04. However, i require v0.8.0 to be installed.
Also, i need v0.6.1 to be installed additionally for backward compatibility.
Any solution for these two cases ?
You will probably need to install from source rather than use a distro package. Unfortunately, it sounds like the Ubuntu distro package hasn't been updated in a while.
Instructions for building and installing from source can be found here: https://capnproto.org/install.html
Old versions are available by changing the version number in the download URL to whichever version you need.
Note that all versions of Cap'n Proto are backwards-compatible, so there should be no need to install older versions, unless you need to run a specific complied binary that was linked against a specific old version.
Today I tried to upgrade the "icu" pacman package, because I need it for NodeJS to work.
After I installed the newest version my system completely broke, I can't even start it up anymore.
Does anybody know how to fix the problem with Node or how to correctly upgrade the "icu" package?
You shouldn't upgrade individual packages. Instead, you should upgrade the entire system. The reason for this is that the dependencies that exist between packages will break sooner or later if you perform partial upgrades.
If you can't boot your system any more, try booting on the installation media, mount the installed disk, arch-chroot into it and run pacman -Syu.

I am unable to successfully utilize the pdf-tools package.
Environment:
macOS Monterey 12.0.1
Emacs 27.2
To the best of my understanding, I have followed the installation instructions as outline on https://github.com/politza/pdf-tools:
I've installed and confirmed that the installations of poppler and automake are up-to-date
Though it doesn't seem to be required for the MacOS install, I've installed and confirmed that the installations of gcc and glib are up-to-date.
I've set the PKG_CONFIG_PATH in the init.el file using setenv and confirmed its settings using getenv
(setenv "PKG_CONFIG_PATH" "/usr/local/Cellar/zlib/1.2.8/lib/pkgconfig:/usr/local/lib/pkgconfig:/opt/X11/lib/pkgconfig")
When I try to execute pdf-tools-install and select y in response to the question "Need to (re)build the epdfinfo program, do it now?" I get a compilation error which reads:
mode: compilation; default-directory: "~/.emacs.d/elpa/pdf-tools-20211110.513/build/server/"

For a long while, I had a working pdf-tools setup on my Mac (thank you Andreas Politz and all the other contributors for such a fabulous tool). Suddenly, I don´t really know how or why, it stopped working. I also deleted my homebrew HEAD version of pdf-tools, which made things worse, because I have never again managed to install pdf-tools from Homebrew.
I tried many tweaks, until, finally, I believe the trick that really got things running again was setting the PKG_CONFIG_PATH to everything that mattered inside the init.el file (and downloading XQuartz to get a X11 environment, with the only purpose of having renderproto in the system; it may have been available in an easier way, but it was only like this that I managed to do it).
Here are all the key steps involved in getting pdf-tools back to work in my MacOS Monterey 12.5 running Emacs 28.1 :-)
Download and install XQuartz to get X11 in your Mac (this might be unnecessary, but it helped me).
In case you haven't already, install other dependencies through homebrew:
brew install poppler automake pkg-config
Through M-x list-packages, install pdf-tools.
In your init.el file, set the PKG_CONFIG_PATH using setenv:
(setenv "PKG_CONFIG_PATH" "/usr/local/Cellar/zlib/1.2.12/lib/pkgconfig:/usr/local/lib/pkgconfig:/usr/X11/lib/pkgconfig:/usr/local/Cellar/poppler/22.06.0_1/lib/pkgconfig:/opt/x11/share/pkgconfig")
Of course, you will have to use your own version numbers and update them every time you upgrade zlib and poppler. (zlib now ships with mac OS. If like me you're on mac OS 12.6 or later--and most probably even earlier--you can use /usr/local/opt/zlib/lib/pkgconfig:, which won't have to be updated manually).
Personally, I did all this through the use-package configuration macro that helps organize the init.el file:
(use-package pdf-tools
:ensure t
:config
(setenv "PKG_CONFIG_PATH" "/usr/local/Cellar/zlib/1.2.12/lib/pkgconfig:/usr/local/lib/pkgconfig:/usr/X11/lib/pkgconfig:/usr/local/Cellar/poppler/22.06.0_1/lib/pkgconfig:/opt/x11/share/pkgconfig")
(pdf-tools-install)
(custom-set-variables
'(pdf-tools-handle-upgrades t)))
Close Emacs and and re open it in the Terminal and, type y when prompted to "(re)build the epdfinfo program". (For some reason, rebuilding the epdfinfo program seems to work better in the Terminal than in the GUI version of Emacs).
That's all it should take to get pdf-tools to work. It did for me, anyway.
try installing the package 'autoconf' the same way you installed 'automake'.
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.
