The Mesa project has updated its Docker-based build infrastructure to include 32-bit libraries in the x86_64 LLVM SDK container images. The change enables multilib builds within Mesa's CI pipeline, allowing 32-bit Mesa drivers to be compiled alongside their 64-bit counterparts in the same container environment.
32-bit Mesa builds remain important for Linux gaming, where Proton and Wine frequently need 32-bit Vulkan ICDs and OpenGL drivers to run older and 32-bit Windows titles. Projects like LLVMpipe and other LLVM-dependent Mesa drivers rely on these SDK containers for continuous integration and testing. Previously, building 32-bit variants required separate container images or manual library installation, adding friction to the development workflow.
The infrastructure-level fix is a small but practical improvement for Mesa contributors working on multilib support, and it should help keep 32-bit driver builds from falling behind their 64-bit equivalents as Mesa's LLVM-based drivers continue to evolve.
