Other stuff

examples

are small examples of how to use github.com/csaf-poc/csaf_distribution as an API. Currently this is a work in progress, as usage of this repository as a library to access is not officially supported, e.g. see https://github.com/csaf-poc/csaf_distribution/issues/367 .

Setup

Binaries for the server side are only available and tested for GNU/Linux-Systems, e.g. Ubuntu LTS. They are likely to run on similar systems when build from sources.

The windows binary package only includes csaf_downloader, csaf_validator, csaf_checker and csaf_uploader.

The MacOS binary archives come with the same set of client tools and are community supported. Which means: while they are expected to run fine, they are not at the same level of testing and maintenance as the Windows and GNU/Linux binaries.

Prebuild binaries

Download the binaries from the most recent release assets on Github.

Build from sources

• A recent version of Go (1.21+) should be installed. Go installation

• Clone the repository git clone https://github.com/csaf-poc/csaf_distribution.git

• Build Go components Makefile supplies the following targets:

  • Build for GNU/Linux system: make build_linux
  • Build for Windows system (cross build): make build_win
  • Build for macOS system on Intel Processor (AMD64) (cross build): make build_mac_amd64
  • Build for macOS system on Apple Silicon (ARM64) (cross build): make build_mac_arm64
  • Build For GNU/Linux, macOS and Windows: make build
  • Build from a specific git tag by passing the intended tag to the BUILDTAG variable. E.g. make BUILDTAG=v1.0.0 build or make BUILDTAG=1 build_linux. The special value 1 means checking out the highest git tag for the build.
  • Remove the generated binaries und their directories: make mostlyclean

Binaries will be placed in directories named like bin-linux-amd64/ and bin-windows-amd64/.
