libresolvconf is a C library that parses resolv.conf files and can load ENVIRONMENTAL variables into a predefined structure. It uses Ragel to build FSM that parse and validate the input, while striving for performance and reliability. It also comes with utility resolvconf-checker, that check syntax of resolv.conf file.

It supports multiple resolv.conf file standards and is syntax compatible under Linux and OpenBSD. Tested platrofms are Ubuntu and MacOS.

Uses the CMake build system.

1. Before building, install the cmake, C compiler(gcc, clang, ...), libcriterion-dev and ragel dependencies.

2. Access the working directory and download the source code from the repository

cd <working directory>
git clone https://github.com/Payne-X6/libresolvconf.git

3. Create a build directory

cd libresolvconf
mkdir build

4. Build from source

cd build
cmake ..
make -j`nproc`

5. Optionally, you can install the library

sudo make install
