Configuring the Build System
|
|
Update: 04 May 2006
|
|
|
|
|
|
1. Overview
|
|
|
|
The "configure" script in pjproject root directory is not an autoconf script,
|
|
but it's just a custom script to generate "build.mak" for the build system.
|
|
The "build.mak" file declares the following global Makefile variables:
|
|
|
|
MACHINE_NAME
|
|
The processor and hardware platform of the target. For each MACHINE_NAME,
|
|
there must be matching "m-*.mak" entry in "build/" subdirectory. For
|
|
example, when MACHINE_NAME is declared as "i386", then there must be
|
|
"m-i386.mak" file in "build/" subdirectory.
|
|
|
|
OS_NAME
|
|
Operating system name, determines which "os-*.mak" in "build/" dir to use.
|
|
|
|
HOST_NAME
|
|
Build host name, determines which "host-*.mak" to use.
|
|
|
|
CC_NAME
|
|
Compiler name, determines which "cc-*.mak" to use.
|
|
|
|
TARGET_NAME
|
|
Determines suffix to be added to output files (for example,
|
|
"libpjsip-i386-linux-gcc.a"). The value normally is equal to
|
|
$(MACHINE_NAME)-$(OS_NAME)-$(CC_NAME), but it can contain any value.
|
|
|
|
CROSS_COMPILE
|
|
Determine the prefix to be applied when invoking build tools (for
|
|
example, "powerpc-rtems-"). The default is empty.
|
|
|
|
|
|
At present, the configure script CAN NOT be used for configuring cross
|
|
compilation. For cross compiling, you must create the "build.mak" file
|
|
manually.
|
|
|
|
|
|
2. Supported Hosts and Targets
|
|
|
|
The number of supported hosts and targets will (hopefully) increase over time.
|
|
See "build/" subdirectory for list of supported machines, OSes, hosts, and
|
|
compilers.
