What is detect-libc?

The detect-libc npm package is a simple utility for detecting the C standard library version on a system. It is primarily used in node-gyp and prebuild-install to ensure binary compatibility with the host system's libc when compiling native addons.

What are detect-libc's main functionalities?

Detecting the system's C library

This feature allows you to detect the C library family (e.g., glibc, musl) and version used by the system. This is useful for determining binary compatibility for native modules.

const detectLibc = require('detect-libc');

const libcFamily = detectLibc.family;
const libcVersion = detectLibc.version;

console.log(`Libc Family: ${libcFamily}`);
console.log(`Libc Version: ${libcVersion}`);

Checking if the system uses a specific C library

This feature provides a boolean check to determine if the system is using a non-glibc C library, which can be important for certain build processes and compatibility checks.

const detectLibc = require('detect-libc');

if (detectLibc.isNonGlibcLinux) {
  console.log('The system uses a non-glibc C library.');
} else {
  console.log('The system uses glibc.');
}
