GnuPG 2.2.x Build Instructions

Below are my build instructions for GnuPG 2.2.9, released on July 12th, 2018. These instructions are built for a headless Centos 7 LTS server (specificaly the openshift/base-centos7 docker image).

You use the below install script to install GnuPG 2.2.x by running the following commands:

# if you are root in a docker image:
curl -OL "https://gist.githubusercontent.com/simbo1905/ba3e8af9a45435db6093aea35c6150e8/raw/83561e214e36f6556fd6b1ec0a384cf28cb2debf/install-gnupg22.sh" && bash ./install-gnupg22.sh
# else if you need to sudo to do the installs:
curl -OL "https://gist.githubusercontent.com/simbo1905/ba3e8af9a45435db6093aea35c6150e8/raw/83561e214e36f6556fd6b1ec0a384cf28cb2debf/install-gnupg22.sh" && sudo -H bash ./install-gnupg22.sh

echo "Complete!!!"

Is ~/.gnugp a typo?

I have gpg 2.0.22 installed on my machine after running this script everything seems to work and message Complete!!! is printed however I'm not able to find gpg 2.2.9 anywhere in my filesystem. (I have checked /usr/bin and /usr/local/bin). Where can I find installed binaries?

Here is some code which maybe helpful for you in inserting versions if you wanted different ones.

export libgpg_error_version="1.47"
export libgcrypt_version="1.10.3"
export libassuan_version="2.5.6"
export libksba_version="1.6.5"
export npth_version="1.6"
export pinentry_version="1.2.1"
export gnupg_version="2.4.4"
