The Pigweed host target is used for unit testing and some host side tooling.
To build for this target, invoke ninja with the top-level “host” group as the target to build.
$ ninja -C out host
There are two host toolchains, and both of them can be manually invoked by replacing host with host_clang or host_gcc. Not all toolchains are supported on all platforms. Unless working specifically on one toolchain, it is recommended to leave this to the default.
Tests are automatically run as part of the host build, but if you desire to manually run tests, you may invoke them from a shell directly.
… code:: sh
The host target implements a system RPC server that runs over a local socket,
defaulting to port 33000. To communicate with a process running the host RPC
pw rpc -s localhost:33000 <protos>.
The host target exposes a few options that may be used to change the host build behavior.
Pigweed includes a number of host-only tooling that may be built as part of the host build. These tools are included as part of the bootstrap, so it’s only necessary to enable this setting when modifying host tooling. This is disabled by default.
