Summary

  • Use gcc-toolset-14 in build_vllm_s390x.sh for s390x builder dependencies.
  • Replace gcc with gcc-toolset-14 in the s390x runtime stage in Dockerfile.konflux.cpu
  • Enable gcc-toolset-14 during vLLM wheel build on s390x (required for torch 2.11.0+cpu).

Jira

RHOAIENG-70232

Background

Torch 2.11.0+cpu requires GCC 14 on s390x. The Konflux image previously had gcc 11.5.0, causing build/runtime issues.
