Our codebase is triggering this bug:
https://sourceware.org/bugzilla/show_bug.cgi?id=13669
Therefore I need to compile GDB with the workaround hack, Unfortunately, I can't seem to find a list of configure options, or some kind of "enable all" flag.
I am using the CentOS 7 distro. The gdb included is version "Red Hat Enterprise Linux 7.6.1-100.el7" It seems to be installed to /usr/bin/gdb
The features I need is python pretty printing, as well as anything else eclipse might need under the hood.
This is my last attempt, but it still doesn't seem to have what i need.:
CC=gcc ./configure --with-python=yes --with-zlib
Specifically, eclipse still can't display pretty printed values.
Also, is there any way to overwrite the package installed version so that it "inherits" the configuration?
---edit---
Also, is there a good way to turn this into a yum installable package? Once i get this to work i need to distribute it to about 50 developer machines.
FYI the issue has been fixed: https://sourceware.org/ml/gdb-patches/2017-10/msg00836.html

I installed ghcup and:
Stack 2.9.1
HLS 1.8.0
cabal 3.6.2
GHC 9.2.5
All of them are the recommended versions(I verified it using ghcup tui). Then I installed the Haskell extension in VSCode. Unfortunately, it doesn't work. I get syntax highlighting (from the Haskell Syntax Highlighting extension, which seems to be automatically installed alongside the Haskell extension) but there is no Intellisense, no code completion, no error detection and no interactive mode (-->>> evaluation). I experimented with different folders and haskell files. The filetype is correct, because every time I open a .hs file, the Haskell extension checks for updates. I even installed Codium, because I suspected a fault in VSCode, but it was the same there as well.
The hsl language server doesn't seem to be working in Neovim, either. I uninstalled ghcup (ghcup nuke) and reinstalled again. The result is exactly the same. I prepended the PATH and chose vanilla and non-vanilla Stack integration in either installations.
Am I doing something wrong?
OS: Linux Mint on Ubuntu 20.04.1, kernel 5.15.0-56.
After around 10 tries, I managed to fix the problem. It turned out I had three problems:
I had only 12 GB free on my Linux partition, but it seems more are needed. I realised it, when it turned out some haskell-language-server files were missing. I enlarged my Linux partition (something I should have done months ago). The new installation installed all files
The Haskell Language Server HLS was not added to the PATH. I solved it by putting this snippet in ~/.ghcup/config.yaml:
"haskell.serverEnvironment": {
"PATH": "${HOME}/.ghcup/bin:$PATH"
}
The server was now discovered by the Haskell VS Code extension but crashed 5 times and gave up on trying. Restarting it manually didn't help. I opened the logs: View->Output->Haskell and saw the error:
haskell-language-server-wrapper: /lib/x86_64-linux-gnu/libc.so.6: version `GLIBC_2.32' not found (required by haskell-language-server-wrapper)
It turns out, my Linux Mint distribution uses GLIBC_2.31, not 2.32. This is a very important library, which most applications on the system use. If you are a newbie, it is strongly advised that you DO NOT update it manually.
Instead, what I did, was install a version of the HLS, which used GLIBC_2.31. This problem occured in September and was "fixed" but apparently not very well. There are two options:
download the HLS deb10 version manually (didn't work for me):
ghcup install hls -u https://downloads.haskell.org/~hls/haskell-language-server-1.8.0.0/h
download using ghcup tui HLS version 1.7.0.0 (or whatever newest, which uses your glibc version) and a GHC, which supports that particular version of the HLS (in my case 9.0.2).
I think it's a good idea to preemptively reinstall the extension, in case it used the PATH to configure the HLS, so that its settings are restored to default. It takes up to 20 seconds to initialize the server, so be patient. You can see what's happening in the Output window and verify there are no more errors.
I hope this helps.
I need to install SUMO 0.30.0 to be used with the VEINS_INET subproject in veins 4.6. I have tried following the instructions here and suggestions from forums but haven't had any luck being able to install sumo. I run ./configure (trying various tool/library options) then run sudo make but all I get is target marouter failed or nothing to be done for 'install-exec-am' 'install-data-am'.
Does anyone know how to install sumo-0.30.0 from source and/or make the veins_inet subproject work with the latest version of sumo-0.32.0?
Don't run sudo make.
Don't run sudo make.
Your problem is probably related to a dependency/packaging change in 16.04, which is explicitly pointed out in the veins tutorial:
Note that Ubuntu 16.04 no longer includes libproj0; this can be worked around by temporarily adding the packet repository of, e.g., Ubuntu Vivid when installing this package.
Short answer: Unfortunately this means that long-term, you're going to either have to package SUMO yourself, use the versions someone else compiled (see this launchpad for example) or rely on an old version.
Long answer:
In general, I would recommend building SUMO from source by building its' dependencies from source, since I've encountered this problem on various distributions. In particular, the fox, proj and gdal libraries tend to be packaged in different versions, and along with changes in the SUMO source code. I currently use this script (with the package versions downloaded) to compile SUMO -- but this is for 0.30.0, and it breaks if any of the referenced source packages are moved (which happens quite often). My general recommendation would be to either use a completely isolated version of SUMO (i.e., compiling by hand as much as possible) or relying on a pre-packaged version (see above), as long as that version is recent enough to work with VEINS.
I'm a RHEL newbie. I'm used to a non-Linux Unix, which has a fundamentally different way of dealing with packages.
I want to install ipython for a user on a vanilla RHEL7 system with yum as the package manager.
"yum install python" was fairly straightforward, but given that I'm new to the OS and I don't completely understand what ipython is, I am stumped as to how to proceed.
"yum install ipython" obviously doesn't work and every possible solution seems to require the installation of something else that I don't know how to install in a reasonable manner.
I am trying to keep things as generic as possible so it will be obvious how to update/remove software in the future, so anything that can be done with yum, would be probably preferable.
Installation instructions refer to pip, which I don't have. I possibly need setuptools to run pip, but I can't figure out the appropriate way to get that either. Maybe I can get one or either by installation the EPEL bundle of packages, but I can't find those for RHEL7, at least not in a way that doesn't seem like a "download and install this random file, trust us" method, which seems irresponsible.
Another option is anaconda. Again, there doesn't seem to be a yum-related way to install this, and anaconda itself is only a means to an end to download ipython, so that'd be two levels of abstraction away from the goal.
Additionally, do I even want "ipython" these days, or do I want "jupyter"?
All I care about is that the user should be able to type in "ipython" at the prompt and get the thing he is expecting.
Also, the python installed by yum is 2.7.5-48.el7, which does not seem to be current. I don't care about using the current version unless that prevents me from successfully installing ipython in some other manner, but I thought it might be relevant.
Any suggestions for how to install this thing is the most easily maintainable way? Do I not want the yum version of python?
Thanks for your patience.
Install python-pip from EPEL repository first ( https://fedoraproject.org/wiki/EPEL - it's compatible with all Red Hat entrprise Linux distros - be it CentOS, RHEL, Oracl, ScientificLinux or whatever), (or if you don't trust EPEL repo providers you can use get-pip.py ( https://bootstrap.pypa.io/get-pip.py ) script, but then you have to trust its providers instead) then install via
pip install ipython
I was using ubuntu 12.04 until 12.10 was released. I used ubuntu for software development and after installing 12.10, i noticed that the perl version (5.14) shipped with 12.10 does not include the Switch.pm module needed while building WebKiT-GTK.
Looking around on the internet i found few suggestions indicating that i should install something call p5-switch from something called ports. I have looked around and was not able to get this done. I am not a perl guy and have no idea where i can get this package.
Can someone please help me as to
1. Where to download the package for ubuntu 12.10
2. In case it is not a .deb, How do i install it.
OR
1. At least be able to downgrade the perl installation to something lower than 5.14
Thanks and Regards

sudo apt-get install libswitch-perl
will install it for you.
"ports" is a *BSD packaging system of sorts, not what you should be looking for.
You can find what package has a particular perl module by going to packages.ubuntu.com, entering Module/Name.pm (in this case, Switch.pm) in the "Search the contents of packages" form and checking "packages that contain files whose names end with the keyword" and selecting the desired distribution, then making sure you ignore false hits like CGI/Switch.pm in the results. Debian has the identical search for its packages at packages.debian.org.
(Note that Switch.pm has serious limitations, was never really intended to be used in production, and should certainly not be used in new code.)
Do make sure you've checked properly that there isn't the Switch module available via apt. If it is available, that's the one you want.
No, then you've two options the longer, correct way and a shorter way that's not quite as clean.
1. Longer
Install cpanm and perlbrew with apt. The perlbrew tool lets you install a complete version of Perl from scratch in a separate directory. Set up a user for your webkit building, run perlbrew as that user, install your perl. Then, use cpanm to install required modules and you are done. A bit of googling will get you step-by-step examples of how to use these tools. If anything goes badly wrong, you can just delete all the files in that user's home directory and start again - all you waste is a little time.
The reason experienced Perl people prefer this is that it keeps the perl you want for webkit-gtk separate from your system perl that ubuntu's packages will expect to be unchanged from the one they ship.
2. Shorter
Install cpanm with apt. As root, run "cpanm Switch" and it will install the Switch.pm package and any dependencies. It will also upgrade any already installed packages it thinks it needs to. This last step is why this option isn't ideal. In the (rare) case when the update isn't compatible with something else on your system uninstalling is fiddly.
The instructions how to install GoClipse have been followed.
I'm not getting any autocomplete stuff happening at all, either for local packages that I write, for built in stuff, or for GAE stuff (I have downloaded Go src to the SDK folder as the wiki states).
Are there any settings that I can check to ensure it is set up correctly? Is autocomplete supposed to work in the current version?
As the GoClipse with AppEngine article you linked to says:
We assume the reader has a working copy of GoClipse running in their Eclipse environment.
so that’s not the article you want to refer to. Instead, check for GoClipse.
The auto completion is named content assist in eclipse. The GoClipse features state:
Now delivered with content assist via Gocode for Windows, OS X 64bit, and Linux 64bit.
Gocode is an auto-completion daemon. So you will also have to install and run that one besides your eclipse + GoClipse.
There is a bug in the current version of Goclipse for the Linux platform. It currently delivers a prebuilt version of gocode for Windows, 64 bit OS X, and 64 bit Linux. I have only been able to test it locally with limited resources, so I really depend on users to report the problems they find at:
http://code.google.com/p/goclipse/issues/list
If you are having problems, I urge you to download and install gocode into your $GOROOT/bin directory and see if that helps. Otherwise, the fix will come in the next release in a few days.
Also, sorry for causing you any trouble and thank you for trying Goclipse.
If you are not using a gocode upstream (but the one shipped with Eclipse) on Linux you are also no be able to build your application with CRTL+F11, although just clicking in Run->Run is going to work.
So, I strongly recommend to update your gocode on Linux, as simple as:
$ sudo GOPATH=/opt/go/ go get -u github.com/nsf/gocode
