Extensions to build when installing the gem, specifically the paths to extconf.rb-style files used to compile extensions.

These files will be run when the gem is installed, causing the C (or whatever) code to be compiled on the user’s machine.

Usage:

Example

spec.extensions << 'ext/rmagic/extconf.rb'

See Gem::Ext::Builder for information about writing extensions for gems.
