= Building for ZeroTier Support
|
|
|
|
If you want to include support for the experimental ZeroTier
|
|
transport (`zt://` URLs), you should follow these directions.
|
|
|
|
Staysail has created a package that builds a clean CMake project
|
|
that you can import.
|
|
Download this from https://github.com/staysail/libzerotiercore[GitHub].
|
|
|
|
|
|
IMPORTANT: ZeroTierOne is licensed under different terms than NNG.
|
|
You are responsible for reading those license terms, and ensuring that
|
|
your use conforms to them.
|
|
|
|
IMPORTANT: The ZeroTier transport, and these build instructions,
|
|
are experimental.
|
|
We expect both to change over time as ZeroTier and the NNG `zt://` transport
|
|
both mature.
|
|
As always, _caveat emptor_.
|
|
|
|
== Building libzerotiercore
|
|
|
|
Using "CMake", you can build libzerotiercore
|
|
using any normal CMake generator.
|
|
You should install it as well.
|
|
Normally it will install into `/usr/local` on
|
|
Linux and UNIX systems.
|
|
|
|
== Configuring NNG with ZT
|
|
|
|
You will need to enable ZeroTier within NNG using the CMake option `NNG_TRANSPORT_ZEROTIER=ON`.
|
|
If you have installed the libzerotiercore in
|
|
one of the default locations, then that should be all
|
|
that is needed.
|
|
|
|
If you have specified a different location, you will
|
|
need to inform CMake of this by setting the CMake
|
|
variable `-Dzerotier_DIR=<where you installed it>`
|
|
|
|
== Example
|
|
|
|
The following example would work on either Linux or macOS, and assumes
|
|
that we have checked out github source trees into `$HOME/work`.
|
|
|
|
[source, sh]
