Packaging scripts to prebuild libvips and its dependencies - you're probably looking for https://github.com/lovell/sharp

Packaging scripts

libvips and its dependencies are provided as pre-compiled shared libraries for the most common operating systems and CPU architectures.

During npm install, these binaries are fetched as tarballs from this repository via HTTPS and stored locally within node_modules/sharp/vendor.

The base URL can be overridden using the SHARP_DIST_BASE_URL environment variable.

Creating a tarball

Most people will not need to do this; proceed with caution.

Run the top-level build script without parameters for help.

Linux

One build script is used to (cross-)compile the same shared libraries within multiple containers.

• x64 glibc
• x64 musl
• ARMv6
• ARMv7-A
• ARMv8-A

Windows

The output of libvips' build-win64 "web" target is post-processed within a container.

OS X

See package-libvips-darwin.
