lldpd | implementation of IEEE 8021ab (LLDP) | TCP library

For general instructions prefer the website, including building from released tarballs.
You can use Docker to run lldpd:. In place of latest which provides you with the latest stable version, you may use 1, 1.0, 1.0.12 to match specific versions, or master to get the development version.
The same procedure as above applies for macOS. However, there are simpler alternatives:. If you don't follow the above procedures, you will have to create the user/group _lldpd. Have a look at how this is done in osx/scripts/postinstall.
Use Homebrew: brew install lldpd # Or, for the latest version: brew install https://raw.github.com/lldpd/lldpd/master/osx/lldpd.rb
Build an macOS installer package which should work on the same version of macOS: mkdir build && cd build ../configure --prefix=/usr/local --localstatedir=/var --sysconfdir=/private/etc --with-embedded-libevent \ --without-snmp make -C osx pkg If you want to compile for an older version of macOS, you need to find the right SDK and issues commands like those: SDK=/Developer/SDKs/MacOSX10.6.sdk mkdir build && cd build ../configure --prefix=/usr/local --localstatedir=/var --sysconfdir=/private/etc --with-embedded-libevent \ --without-snmp \ CFLAGS="-mmacosx-version-min=10.6 -isysroot $SDK" \ LDFLAGS="-mmacosx-version-min=10.6 -isysroot $SDK" make -C osx pkg With recent SDK, you don't need to specify an alternate SDK. They are organized in a way that should enable compatibility with older versions of OSX: mkdir build && cd build ../configure --prefix=/usr/local --localstatedir=/var --sysconfdir=/private/etc --with-embedded-libevent \ --without-snmp \ CFLAGS="-mmacosx-version-min=10.9" \ LDFLAGS="-mmacosx-version-min=10.9" make -C osx pkg You can check with otool -l that you got what you expected in term of supported versions.
Don't clone the repo or download the master branch from GitHub. Instead, download the official release from the website https://lldpd.github.io/. Unpack into a working directory. Download the Android NDK (version 22 or later). Unpack into a working directory next to the lldpd directory. Install automake, libtool, and pkg-config. (sudo apt-get install automake libtool pkg-config).

In the root of the lldpd directory, make a compile.sh file containing this script:
In the Android NDK directory, locate the toolchains/llvm/prebuilt/linux-x86_64 directory and change the TOOLCHAIN variable of the above script to match the path where the linux-x86_64 directory resides.
Determine the CPU architecture target (adb shell getprop ro.product.cpu.abi). Change the TARGET variable in the above script to match the target architecture. The target name will not exactly match the output of the adb command as there will be a trailing suffix to the target name, so look in the linux-x86_64/bin directory for the clang file that starts with the CPU architecture target. Don't include the API version in the target name.
Set the API variable in the script above to your target API version. Check in the same linux-x86_64/bin to ensure the API you are targeting has a supported clang file for that CPU architecture and version. As of this writing, there is support for API 21-30 included for all architectures and some CPU architectures supported back to version 16.
Run the compile script (./compile.sh).
Copy the ./bin/* and ./lib/*.so files from lldpd/build/install/system to the target system (./bin/* to /system/bin, ./lib/*.so to /system/lib64):
