Example applications

Run commands from the repository root. These small deterministic apps consume public SDK targets through the CMake consumer templates.

Build and run

cmake -S examples/fetch_content_consumer -B build-example \
  -DA2A_EXAMPLE_APP=hello_agent -DA2A_CPP_GIT_TAG=v0.5.2
cmake --build build-example --parallel
./build-example/a2a_example

Replace hello_agent with an app below. For an installed SDK, configure examples/installed_package_consumer with -DCMAKE_PREFIX_PATH=<install-prefix>. Multi-configuration Windows builds place the executable under RelWithDebInfo/.

Each app links a2a::client, a2a::server and a2a::core through the consumer templates, prints concise task/status/event or delivery output, and exits nonzero on an SDK error. Network streaming examples have their own client and server guides.
