C++ Boost

Boost.Build

variables

Introduction

Boost.Build's behaviour can be controlled by setting of variables either from the shell environment or using the "-sVARIABLE_NAME=value" Jam command line option. Most of these variables are used internally and don't need to be manipulated by the user.

Variables

 
Variable Name Semantics Notes
AS
 Command to compile assermbler source files.
ASFLAGS
 Flags to pass to As command.
