C++ compiler?

[operadude]

Just install build-essential if you need to build something. It's not on the ISO because it's not a dependency to any of the stuff that's there and not everybody compiles stuff and in general people who know how to compile stuff know how to install the compiler, it's really not hard, it takes a minute. If you really like it on the ISO, install it, take a snapshot and it will always be there.

Thanks for that!

I was also wondering why my C++ "Hello, World!" program was not working on MX-23, then I did this:

Code: Select all

$ which g++
opera-dude@GA-H270-HD3:~
$ apt policy g++
g++:
  Installed: (none)
  Candidate: 4:12.2.0-3
  Version table:
     4:12.2.0-3 500
        500 http://deb.debian.org/debian bookworm/main amd64 Packages

Questions:
For a learning C++, does one need "build-essential"?
And if only concerned about running C++ programs, does this suffice? :

Code: Select all

$ sudo apt install g++

The following additional packages will be installed:
  g++-12 libstdc++-12-dev
Suggested packages:
  g++-multilib g++-12-multilib gcc-12-doc libstdc++-12-doc

And if so, should one also install the suggested:

Code: Select all

g++-multilib
g++-12-multilib 

?

[Stevo]

build-essential will also install and configure essential tools, such as "make".

You don't need multilib packages unless you plan to cross-compile.

Last, is the output when I try to install the wifi driver:

Code: Select all

wyckyd@ucs:~/Downloads/88x2bu-20210702-main
$ sudo ./install-driver.sh
[sudo] password for wyckyd:
A required package is not installed.
Please install the following package: gcc
Once the package is installed, please run "sudo ./install-driver.sh"

Hope this helps. I still need to be able to install build-essential offline.

TIA,

build-essential will also install and configure essential tools, such as "make".

Great.

I tried the steps that they outlined on the link, but still nothing.
Thank you for your input though. It is very much appreciated. I am willing to try almost anything to get this working right.

These are links to the packages you would need to download to install build-essential:

You would download them and save all in the same folder. I think the Open With "Deb Installer" rightclick action will then install them for you if you right click on one of them.


edit: the links are only for MX23 (64bit) and may change in the future with package updates

edit 2: right click on the build-essential .deb file

I really would like to be able to install the drivers for my wifi adapter in MX 23.1 KDE AHS. I downloaded the MX 23.1 iso image and that is what I am using. I really like and enjoy MX! I have enjoyed MX linux since MX 18.

TIA

[WyCKyD]

I formatted and reinstalled MX 21.3 and then installed the wifi drivers without incident. I will try to upgrade to MX 23.1 later today.
It's a shame that the necessary files for compiling wifi drivers was left out of the MX 23.1 iso.
