This repository holds the recipe for skhep/manylinuxgcc-* images. These produce manylinux1 wheels with some caveats with a modern GCC.

GCC 10 is not compatible with RHEL 5, so this is capped at version 9.

Example build

This is an example build on a 24 core machine:

docker build -t skhep/manylinuxgcc-x86_64 . -f Dockerfile --build-arg CORES=48

Here is a 32-bit build:

docker build -t skhep/manylinuxgcc-i686 . -f Dockerfile --build-arg CORES=48 --build-arg ARCH=i686

Tags

Make sure you tag accordingly. Also, do not use the default "latest" tag if you are not building the latest GCC. Here are the current set of tags:

docker tag skhep/manylinuxgcc-i686:latest skhep/manylinuxgcc-i686:9
docker tag skhep/manylinuxgcc-i686:latest skhep/manylinuxgcc-i686:9.3
docker tag skhep/manylinuxgcc-x86_64:latest skhep/manylinuxgcc-x86_64:9
docker tag skhep/manylinuxgcc-x86_64:latest skhep/manylinuxgcc-x86_64:9.3
docker push skhep/manylinuxgcc-i686
