pcapplusplus-sys

Compile PcapPlusPlus and make its library and header files available.

Two environment variables will be made available to build.rs of dependent crates:

• DEP_PCAPPLUSPLUS_INCLUDE contains the path to PcapPlusPlus header files
• DEP_PCAPPLUSPLUS_LIB contains the path to the compiled PcapPlusPlus libraries

To use PcapPlusPlus with cxx, use something like this in your build.rs:

let mut cpp = cxx_build::bridge("src/bridge.rs");

// Set include path for PcapPlusPlus
let pcpp_include = env::var_os("DEP_PCAPPLUSPLUS_INCLUDE")
    .expect("Environment variable DEP_PCAPPLUSPLUS_INCLUDE should have been set");
cpp.include(pcpp_include);

// ...

You also need to link to the PcapPlusPlus libraries and possibly libpcap:

// Link to PcapPlusPlus libraries
let pcpp_lib = env::var("DEP_PCAPPLUSPLUS_LIB")
    .expect("Environment variable DEP_PCAPPLUSPLUS_LIB should have been set");
println!("cargo:rustc-link-search=native={}", pcpp_lib);
println!("cargo:rustc-link-lib=static=Common++");
println!("cargo:rustc-link-lib=static=Packet++");
println!("cargo:rustc-link-lib=static=Pcap++");

// Link to libpcap
println!("cargo:rustc-link-lib=dylib=pcap");
