Building code for multiple architectures
GitLab CI enables you to build artifacts for multiple architectures at once. This can easily speed up software builds by two or three times since, with multiple architectures, you typically have to build the software multiple times for each architecture. Here, we’re going to use CI jobs and pipelines to execute a software build for multiple architectures at the same time.
When building software for multiple architectures, there are some special requirements. The first requirement is that you must have GitLab Runners installed and configured on a machine running each architecture. For this section, we’re going to use three platforms as an example: x86_64, arch64, and powerpc. In this case, the expectation would be that you have a machine for each of the three architectures, with a GitLab Runner installed on it. That GitLab Runner also needs to have a tag assigned to it for which architecture it is running on.
