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.

AWK
Command to process awk commands.

CHMOD
Command to set the permissions of files.

CP Command used to copy files.
CRELIB
?

DLLMODE
Permissions to set for generated shared library files.

DLL_AS_LIB
Platform flag indicating that when linking the platform treats shared libraries as link libraries when linking. Notably Win32 type platforms.

DOT
Representation of current directory in a path.

DOTDOT
Represetation of parent directory in a path.

EXEMODE
Permissions to set for generated executable files.

FILEMODE
Permissions to set for generated regular files.

FORTRAN
Command to compile Fortran source files.

FORTRANFLAGS
Flags to pass to FORTRAN command.

HDRS
Default list of directories of platform headers.

HDRPATTERN
Regex pattern used to match the file part of CPP include directives.

JAMFILE
File to read build instructions/descriptions from.
Default is "Jamfile".
JAMRULES
File to read for global rules and variable.
Default is "Jamrules".

PRELIB
Prefix for generated link library files.

RANLIB
Command to post-process archives or link libraries.
