3. Build LAMMPS

LAMMPS is built as a library and an executable from source code using either traditional makefiles for use with GNU make (which may require manual editing), or using a build environment generated by CMake (Unix Makefiles, Ninja, Xcode, Visual Studio, KDevelop, CodeBlocks and more).

As an alternative you can download a package with pre-built executables or automated build trees as described on the Install doc page.
