4 The Build Script

Rscons looks for instructions for what to build by reading a build script file called Rsconscript (or Rsconscript.rb). Here is a simple example Rsconscript file:

env do |env|
  env.Program("myprog.exe", glob("src/**/*.c"))
end

This Rsconscript file would instruct Rscons to produce a Program target called myprog.exe which is to be built from all C source files found (recursively) under the src directory.

The Rsconscript file is a Ruby script.
