# Vendored Dependencies
|
|
|
|
Dependencies are almost all vendored in at the standard Go `/vendor` path. This allows
|
|
people to build go-ethereum using the standard toolchain without any particular package
|
|
manager. It also plays nicely with `go get`, not requiring external code to be relied on.
|
|
|
|
The one single dependent package missing from `vendor` is `golang.org/x/net/context`. As
|
|
this is a package exposed via public library APIs, it must not be vendored as dependent
|
|
code woulnd't be able to instantiate.
|
|
|
|
To allow reproducible builds of go-ethereum nonetheless that don't need network access
|
|
during build time to fetch `golang.org/x/net/context`, a version was copied into our repo
|
|
at the very specific `/build/_vendor` path, which is added automatically by all CI build
|
|
scripts and the makefile too.

# Debian Packaging
|
|
|
|
Tagged releases and develop branch commits are available as installable Debian packages
|
|
for Ubuntu. Packages are built for the all Ubuntu versions which are supported by
|
|
Canonical:
|
|
|
|
- Trusty Tahr (14.04 LTS)
|
|
- Wily Werewolf (15.10)
|
|
- Xenial Xerus (16.04 LTS)
|
|
- Yakkety Yak (16.10)
|
|
|
|
Packages of develop branch commits have suffix -unstable and cannot be installed alongside
|
|
the stable version. Switching between release streams requires user intervention.
|
|
|
|
The packages are built and served by launchpad.net. We generate a Debian source package
|
|
for each distribution and upload it. Their builder picks up the source package, builds it
|
|
and installs the new version into the PPA repository. Launchpad requires a valid signature
|
|
by a team member for source package uploads. The signing key is stored in an environment
|
|
variable which Travis CI makes available to certain builds.
|
|
|
|
We want to build go-ethereum with the most recent version of Go, irrespective of the Go
|
|
version that is available in the main Ubuntu repository. In order to make this possible,
|
|
our PPA depends on the ~gophers/ubuntu/archive PPA. Our source package build-depends on
|
|
golang-1.7, which is co-installable alongside the regular golang package. PPA dependencies
|
|
can be edited at https://launchpad.net/%7Eethereum/+archive/ubuntu/ethereum/+edit-dependencies
|
|
|
|
## Building Packages Locally (for testing)
|
|
|
|
You need to run Ubuntu to do test packaging.
|
|
|
|
Add the gophers PPA and install Go 1.7 and Debian packaging tools:
|
|
|
|
$ sudo apt-add-repository ppa:gophers/ubuntu/archive
|
|
$ sudo apt-get update
|
|
$ sudo apt-get install build-essential golang-1.7 devscripts debhelper
|
|
|
|
Create the source packages:
|
|
|
|
$ go run build/ci.go debsrc -workdir dist
|
|
|
|
Then go into the source package directory for your running distribution and build the package:
|
|
|
|
$ cd dist/ethereum-unstable-1.5.0+xenial
|
|
$ dpkg-buildpackage
|
|
|
|
Built packages are placed in the dist/ directory.
|
|
|
|
$ cd ..
|
|
$ dpkg-deb -c geth-unstable_1.5.0+xenial_amd64.deb
|
