PROBLEM

I was trying to install Helix-OS on my Arch Linux at 2019 with ZSH and GCC 8.1 and because it is quite old it recommends OpenFOAM-4.1.

Naturally, there is no package for older OpenFOAM on AUR, so it need to be built from the sources and of course we have to solve some compatibility issues and here is a collection of fixes found on the internet :)

Get the sources

Note that using the folder names with sufix 4.1 for version 4.1 would help some of the scripts.

mkdir -p $HOME/OpenFOAM

Ctrl + Alt + Space

What is squashing?

Squashing is a process in which we squeeze multiple commits into one pretending it is only a single commit.

Basically squashing commits means we are rewriting the history of commits to make them look like single commit.

Why squashing commits is necessary?

Renew GPG key

Given that your key has expired.

$ gpg --list-keys
$ gpg --edit-key KEYID

Use the expire command to set a new expire date:

Setup github project so that after any change to master branch doxygen documentation is generated and pushed to gh-pages by Travis CI

Add clean gh-pages branch to your repository

git checkout --orphan gh-pages
git rm -rf .
echo "my gh-pages branch" > README.md
git add .
git commit -a -m "clean gh-pages branch"
git push origin gh-pages

Start a new one

git clone ssh://[email protected]/package_name.git

	# To fix the " gpg: WARNING: unsafe permissions on homedir '/home/path/to/user/.gnupg' " error

	chown -R $(whoami) ~/.gnupg/

	# Also correct the permissions and access rights on the directory
