GCC 9 and 10 seem to be installed

[AcsPrime]

Hello,

I installed Linux Lite 1h ago and in the package manager I can see gcc 9 and gcc 10:

I really only need the latest and greatest not sure how or why I have two gcc.
I did try to search for gcc 10 in my system but I can only find gcc 9.

How can I just have gcc 10 and not mess anything up?

"Image not found" That img you uploaded, is not there. Use imgur https://imgur.com/ or imgBB https://imgbb.com/  https://www.freecinema2022.gq/forums/intro...uidelines/

You can keep both, and make one the default, just type in a terminal

Code:

sudo update-alternatives --config gcc

You'll see something like

Code:

There are 3 choices for the alternative gcc (providing /usr/bin/gcc).

  Selection    Path            Priority   Status
------------------------------------------------------------
* 0            /usr/bin/gcc-8    90        auto mode
  1            /usr/bin/gcc-9    70        manual mode
  2            /usr/bin/gcc-10  80        manual mode
 
Press <enter> to keep the current choice[*], or type selection number:

Select the one you want to use and that's it.

Hope this helps!

Hey,

This is the image: https://pasteboard.co/JPdQnzZ.png

It seems that I don't have an extra gcc even though I am seeing one there.
Thanks for your help

so gcc is set to gcc9 how to I get rid of gcc9 or at least just switch gcc to gcc10 (and hopefully not cause conflicts on anything)

They may both be there for a reason. You can test your option in a VM first.

The reason is that I installed gcc10, but I was hoping that gcc10 would then be set as default

[Valtam]

Did you read reply #1?

[AcsPrime]

I did! This is what I get:

Code:

~ sudo update-alternatives --config gcc
update-alternatives: error: no alternatives for gcc

Did you read my reply???
The accepted answer talks about update-alternatives which I've already shown says there are no alternatives.

But if this is as simple as just changing the symlink and there will be no issues sure, I'll change.
