That project produces container (e.g., Docker) images, hosted on a dedicated public Docker Cloud site. Those container images are intended to bring Linux-based ready-to-use environment for C++ and Python developers. Both programming languages are indeed related, as Python is built on top of C++ (e.g., a few Python modules need to be compiled with C++). Some basic support for R is also provided.
The supported Linux distributions are Rocky Linux 9, CentOS 10 Stream (not officially released, as of end 2024; see also CentOS Stream 10 compose artifacts), CentOS 9 Stream, CentOS 8 Stream, Fedora 41, Fedora 40, Ubuntu 24.04 LTS (Noble Numbat), Ubuntu 22.04 LTS (Jammy Jellyfish), Ubuntu 20.04 LTS (Focal Fossa), Debian 12 (Bookworm), and Debian 11 (Bullseye).
Every time some changes are committed on the project's GitHub repository, the container images are automatically rebuilt and pushed onto Docker Cloud.
When some more components are needed, which may be of interest to other
C++ and Python developers, the Docker image may be amended so as to add
those extra components.
The preferred way to propose amendment of the Docker image is through
pull requests on the GitHub project.
Once the pull request has been merged, i.e., once the Dockerfile amendment
has been
committed in GitHub,
Docker Cloud then rebuilds the corresponding container images, which become
available for every one to use.
- Start the Docker container featuring the target Linux distribution
(
<linux-distrib>may be one ofrocky9,centos9,centos8,fedora41,fedora40,debian12,debian11,ubuntu2404,ubuntu2204, orubuntu2004):
$ docker pull infrahelpers/cpppython:<linux-distrib>
$ docker run --rm -v ~/.ssh/id_rsa:/home/build/.ssh/id_rsa -v ~/.ssh/id_rsa.pub:/home/build/.ssh/id_rsa.pub -it infrahelpers/cpppython:<linux-distrib>
[[email protected] dev]$ - Setup the user names and email addresses as environment variables for subsequent settings. If you intend to contribute to Fedora/CentOS/RedHat packaging, they should match as much as possible with Pagure, the Fedora Git repository(otherwise, just ignore the RPM packaging part):
[[email protected] dev]$ export FULLNAME="Firstname Lastname"
[[email protected] dev]$ export EMAIL="[email protected]"- Setup the user name and email address for Git:
[[email protected] dev]$ git config --global user.name "$FULLNAME"
[[email protected] dev]$ git config --global user.email "$EMAIL"- Setup the user names and email address for the RPM packaging:
[[email protected] dev]$ sed -i -e "s/Firstname Lastname/$FULLNAME/g" ~/.rpmmacros
[[email protected] dev]$ sed -i -e "s/[email protected]/$EMAIL/g" ~/.rpmmacros- Clone some C++-based project (e.g., OpenTREP is used as an example here):
[[email protected] dev]$ git clone https://github.com/trep/opentrep.git
