grpc.grpc

// Behavioral test for the mcpplibs.grpc package, driven entirely through
// `import grpc;` — there is no <grpcpp/...> include in this file. Every call
// reaches a real symbol in the linked gRPC, so a package that resolved and
// "built" but linked nothing could not pass.
//
// Note the ORDER: textual #includes first, `import grpc;` last. The module
// carries the standard library in its BMI, so a std header included after the
// import arrives twice and GCC fails on std::string's operator==.
// HAVE_GRPC comes from this project's own cfg-gated cxxflags — the package is
// linux/macOS-only (see mcpp.toml), so elsewhere this file is an empty main().
