CentOS 6 is pinned to glibc 2.12, but newer Android build-tools (like
aapt) require glibc 2.14. It's not possible to safely upgrade CentOS
6 distributions to glibc 2.14.
CentOS 7 is pinned to glibc 2.17, which is new enough for newer
Android build-tools. However, I had great difficulty bringing forward
our existing centos:6 Docker image to centos:7. In particular,
installing recent enough Mercurial, git, Python, and pip versions was
difficult enough that I elected to not pursue this approach.
Instead, I've elected to follow glandium's suggestion from
https://bugzilla.mozilla.org/show_bug.cgi?id=1370119#c5: base on
Debian with snapshots.debian.org for reproducibility.
The most significant changes here:
- using Debian's snapshots repository
- using Python and related tools provided by Debian and baked into the
build image
- using the JDK and JRE provided by Debian and baked into the build
image, rather than versions from tooltool (or eventually a toolchain
build)
Moving the builds over to use this image will follow in the patches
ahead.
