You have mentioned below in your linked post,
older compilers only issued a warning for that condition my gcc is version 7.3

Also there is a CAELINUX iso that can be run in a VM or livecd, it has elmer and many other fea tools.

what above means.

My Purpose is I want to Install ELmer. Will you give correct command line.

CAElinux - from where to download.

CAELINUX is a operating system that is pre-loaded with FEA tools including elmer. They have a web site.

VM is virtual machine, a VM can run another operating system within yours. Elmer provides a VM that has all of the Elmer tools installed.

Hi,

I think you could try the following (not 100% sure however since I don't use lubuntu):

* open a terminal
* type (or copy-paste), one by one, the following commands (each followed by the RETURN key ;) )

sudo apt-add-repository ppa:elmer-csc-ubuntu/elmer-csc-ppa
sudo apt-get --allow-unauthenticated upgrade
sudo apt-get install elmerfem-csc-eg

Then it might work.

HTH,
Matthias

OK, I didn't see that mentioned in his posts.
Then I don't know how he can install Elmer.
