Committer: Avi Kivity <avi@scylladb.com> Branch: next Switch to the the CMake-ified Seastar This change allows Scylla to be compiled against the `master` branch of Seastar. The necessary changes: - Add `-Wno-error` to prevent a Seastar warning from terminating the build - The new Seastar build system generates the pkg-config files (for example, `seastar.pc`) at configure time, so we don't need to invoke Ninja to generate them - The `-march` argument is no longer inherited from Seastar (correctly), so it needs to be provided independently - Define `SEASTAR_TESTING_MAIN` so that the definition of an entry point is included for all unit test compilation units - Independently link Scylla against Seastar's compiled copy of fmt in its build directory - All test files use the (now public) Seastar testing headers - Add some missing Seastar headers to source files [avi: regenerate frozen toolchain, adjust seastar submoule] Signed-off-by: Jesse Haber-Kucharsky <jhaberku@scylladb.com> Message-Id: <02141f2e1ecff5cbcd56b32768356c3bf62750c4.1548820547.git.jhaberku@scylladb.com>
Official toolchain for ScyllaDB
While we aim to build out-of-the-box on recent distributions, this isn't always possible and not everyone runs a recent distribution. For this reason a version-controlled toolchain is provided as a docker image.
Obtaining the current toolchain
The toolchain is stored in a file called tools/toolchain/image. To access
the toolchain, pull that image:
docker pull $(<tools/toolchain/image)
A helper script dbuild allows you to run command in that toolchain with
the working directory mounted:
./tools/toolchain/dbuild ./configure.py
./tools/toolchain/dbuild ninja
You can adjust the docker run command by adding more flags before the
command to be executed, separating the flags and the command with --.
This can be useful to attach more volumes (for data or ccache) and to
set environment variables:
./tools/toolchain/dbuild -v /var/cache/ccache:/var/cache/ccache -- ninja
Building the toolchain
Run the command
docker build --no-cache -f tools/toolchain/Dockerfile .
and use the resulting image.
Publishing an image
If you're a maintainer, you can tag the image and push it
using docker push. Tags follow the format
scylladb/scylla-toolchain:fedora-29-[branch-3.0-]20181128. After the
image is pushed, update tools/toolchain/image so new
builds can use it automatically.
For master toolchains, the branch designation is omitted. In a branch, if there is a need to update a toolchain, the branch designation is added to the tag to avoid ambiguity.
