Building Wasmer is bit of a pain, because it requires Rust nightly, and
bunch of OS specific packages.
To make building easier, this adds a "build" script at the top-level
directory, which can be used to build Wasmer within a Docker sandbox
that has all the necessary dependencies installed. The build environment
is based on latest Ubuntu 19.04.
You first need to build a Docker image of the sandbox:
docker build --file Dockerfile.build --tag wasmer-build .
Then, to build Wasmer, run:
./build make
To test Wasmer, run:
./build make test
and so on.
You can also drop into a shell within the Docker with:
./build
The "build" script bind mounts current directory as "/wasmer" in the
Docker container, which allows inspecting the build contents like you
had built them on your local machine.
For future improvements, we should consider:
- Consolidation with existing Dockerfile (that is used for Circle CI)
- Publishing the build sandbox image on Docker Hub so that people
don't have to build it themselves
- Moving dependency installation to separate script, which can be
reused outside of the Docker sandbox.
The work has been inspired by "devtool" in the Firecracker project:
https://github.com/firecracker-microvm/firecracker/blob/master/tools/devtool
and "dbuild" in the Scylla project:
https://github.com/scylladb/scylla/blob/master/tools/toolchain/dbuild

|
|
# This is a script to build Wasmer in a Docker sandbox.
|
|
#
|
|
# To use the script, first make sure Docker is installed. Then build the
|
|
# sandbox image with:
|
|
#
|
|
# docker build --file Dockerfile.build --tag wasmer-build .
|
|
#
|
|
# After the sandbox image is built successfully, you can run commands in it
|
|
# with this script.
|
|
#
|
|
# For example, to build Wasmer, run:
|
|
#
|
|
# ./build make
|
|
#
|
|
# To test Wasmer, run:
|
|
#
|
|
# ./build make test
|
|
#
|
|
# and so on.
