# Installing NDCTL

The `ndctl` utility is used to manage the libnvdimm (non-volatile memory device) sub-system in the Linux Kernel. It is required for several Persistent Memory Developer Kit (PMDK) features if compiling from source. If ndctl is not available, the PMDK may not build all components and features. 

Refer to the [installation instructions](https://docs.pmem.io/ndctl-user-guide/installing-ndctl) in the NDCTL User Guide for [installing prebuilt packages](https://docs.pmem.io/ndctl-user-guide/installing-ndctl/installing-ndctl-packages-on-linux) or [building ndctl from source](https://docs.pmem.io/ndctl-user-guide/installing-ndctl/installing-ndctl-from-source-on-linux).
