Android'de İnşa Etme (Build)
Create two genrules: One to generate the CXX header, and one to generate the CXX source file. These are then used as inputs to the cc_library_static
.
// Generate a C++ header containing the C++ bindings
// to the Rust exported functions in lib.rs.
genrule {
name: "libcxx_test_bridge_header",
tools: ["cxxbridge"],
cmd: "$(location cxxbridge) $(in) --header > $(out)",
srcs: ["lib.rs"],
out: ["lib.rs.h"],
}
// Generate the C++ code that Rust calls into.
genrule {
name: "libcxx_test_bridge_code",
tools: ["cxxbridge"],
cmd: "$(location cxxbridge) $(in) > $(out)",
srcs: ["lib.rs"],
out: ["lib.rs.cc"],
}
- The
cxxbridge
tool is a standalone tool that generates the C++ side of the bridge module. It is included in Android and available as a Soong tool. - By convention, if your Rust source file is
lib.rs
your header file will be namedlib.rs.h
and your source file will be namedlib.rs.cc
. This naming convention isn't enforced, though.
