host

The Pigweed host target is used for unit testing and some host side tooling.

Building

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.

Running Tests

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.

Example:

… code:: sh

$ ./out/host_[compiler]_debug/obj/pw_status/status_test

RPC server

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 server, use pw rpc -s localhost:33000 <protos>.
