Arch Install Issues

[Johny Why]

Hello, 

i'm attempting to install ns3 on arch linux. 

The following command gave errors:

$ sudo pacman -Syu --noconfirm g++ cmake ninja-build ccache python3 python3-dev gsl-bin libgsl-dev libgsl27 libboost-all-dev libgtk-3-dev libfl-dev libxml2 libxml2-dev libopenmpi-dev openmpi-bin openmpi-common openmpi-doc libsqlite3-dev sqlite3 libeigen3-dev qtbase5-dev qtchooser qt5-qmake qtbase5-dev-tools ssh git

can someone who knows what they're doing help out?

Your package names look like Debian/Ubuntu ones. 

Arch has a completely different naming scheme. 

You can find some of the equivalent packages in out gitlab-ci files. 

https://gitlab.com/nsnam/ns-3-dev/-/blob/master/utils/tests/gitlab-ci-daily.yml#L14

You can search for pacman packages with 

pacman -Ss package

Then install with

pacman -S full_package_name

The Syu part fetches a fresh package database (-Sy is equivalent to apt update), 

and upgrades existing packets (-Su is equivalent to apt upgrade).

Hello, as I posted, I did research the Arch names. Please see my post. 

Thx

@johnywhy: I can't stress how disturbing is your reply.

Gabriel did point out that ArchLinux packages are named differently than Ubuntu ones, and you did use the Ubuntu ones without any doubt.

Replying "I did research the Arch names. Please see my post." means that you didn't bother reading Gabriel's post, or you didn't understand it. Either way it is unsettling, at best. At worst it is insulting.

NOW, I could easily point out that the correct set of packages is "pacman -Syu --noconfirm base-devel ninja cmake python ccache gsl gtk3 boost openmpi openssh" (plus others if you want to build the documentation, but you could have found it yourself if you'd had read Gabriel's post, but I won't, because Gabriel already pointed you to the right file.

I could easily point out also that some of the Ubuntu packages that you did try to install are optional, like explained here: https://www.nsnam.org/docs/installation/html/linux.html, but I won't. You didn't read the file Gabriel did point you to, I doubt you'll read the documentation.

The thing I'll do is to give you a warm suggestion: do not upset the people that help others on a volunteer basis.

Hello, there may have been a misunderstanding. My apologies if the misunderstanding was mine. 

Gabriel did point out that ArchLinux packages are named differently than Ubuntu ones, and you did use the Ubuntu ones without any doubt.

Yes, i know that i used the Ubuntu names. I tried to explain that i understood that was the problem, and that's why my build failed. 

I attempted to research the Arch names AFTER my failed build. I posted above some of the Arch names that i found, and others which i couldn't find. 

Sorry if i was unclear. 

some of the Ubuntu packages that you did try to install are optional

I am too ignorant to know which of the optional packages would be need for my application. 

https://www.nsnam.org/docs/installation/html/linux.html

Thank you very much for sharing the Arch script at this link. I guess that's a YAML script? Do you recommend that i execute the entire script?

Thx

Mmm.... perhaps we're caught in a lost-in-translation effect here. Suggestion: explain yourself better next time.

You don't know which packages are needed for your application... solution: start small, add what you need when you discover you need it.
For most cases, I recommend the following:

• ccache (decreases dramatically compilation time after the 1st one)
  
• clang-format (helps fixing formatting mistakes)
  
• gdb (you WILL have a bug, and you WILL need to debug it)
• sqlite (you probably want to dump data into a database)
  
• gsl, boost (not mandatory, but increases the speed of some operations)
  
• libxml2 (to read and write config files in.a structured way)
  
• Wireshark (to read pcap files, but it's not needed for compiling and using ns-3)

everything else is specific to some models. If you need these models you can add libraries later, reconfigure ns-3, and rebuild it.If the libraries are not found, ns-3 will not build the model.

Using the full script in the yaml file is also possible but... mind that these scripts are focused on testing, so they contain the libraries needed for testing.

As an example, we include gtk3 openmpi, and openssh because we test MPI, but this feature is important only in very specific cases (read the MPI documentation).
