Master "Core Components" macros for getting the OS architecture

defines these symbols:

64BIT_TAG

OS_ARCH (from uname -r)

OS_TEST (from uname -m)

OS_RELEASE (from uname -v and/or -r)

OS_TARGET User defined, or set to OS_ARCH

CPU_ARCH (from unmame -m or -p, ONLY on WINNT)

OS_CONFIG OS_TARGET + OS_RELEASE

OBJDIR_TAG

OBJDIR_NAME

Master "Core Components" macros for getting the OS target

Note: OS_TARGET should be specified on the command line for gmake.

When OS_TARGET=WIN95 is specified, then a Windows 95 target is built.

The difference between the Win95 target and the WinNT target is that

the WinNT target uses Windows NT specific features not available

in Windows 95. The Win95 target will run on Windows NT, but (supposedly)

at lesser performance (the Win95 target uses threads; the WinNT target

uses fibers).

If OS_TARGET is not specified, it defaults to $(OS_ARCH), i.e., no

cross-compilation, except on Windows, where it defaults to WIN95.

On WIN32, we also define the variable CPU_ARCH, if it isn't already.

ifndef CPU_ARCH ifeq ($(OS_ARCH), WINNT) CPU_ARCH := $(shell uname -p) ifeq ($(CPU_ARCH),I386) CPU_ARCH = x386 endif endif endif

If uname -s returns "Windows_NT", we assume that we are using

the uname.exe in MKS toolkit.

The -r option of MKS uname only returns the major version number.

So we need to use its -v option to get the minor version number.

Moreover, it doesn't have the -p option, so we need to use uname -m.

ifeq ($(OS_ARCH), Windows_NT) OS_ARCH = WINNT OS_MINOR_RELEASE := $(shell uname -v) # strip leading 0 OS_MINOR_RELEASE := $(patsubst 0%,%,$(OS_MINOR_RELEASE)) OS_RELEASE := $(OS_RELEASE).$(OS_MINOR_RELEASE) ifndef CPU_ARCH CPU_ARCH := $(shell uname -m) # # MKS's uname -m returns "586" on a Pentium machine. # ifneq (,$(findstring 86,$(CPU_ARCH))) CPU_ARCH = x386 endif endif endif

If uname -s returns "CYGWIN_NT-*", we assume that we are using

the uname.exe in the Cygwin tools.

ifeq (CYGWIN_NT,$(findstring CYGWIN_NT,$(OS_ARCH))) OS_RELEASE := $(patsubst CYGWIN_NT-%,%,$(OS_ARCH)) OS_ARCH = WINNT ifndef CPU_ARCH ifeq (WOW64,$(findstring WOW64,$(OS_RELEASE))) OS_RELEASE := $(patsubst %-WOW64,%,$(OS_RELEASE)) endif
CPU_ARCH := $(shell uname -m) # # Cygwin's uname -m returns "i686" on a Pentium Pro machine. # ifneq (,$(findstring 86,$(CPU_ARCH))) CPU_ARCH = x386 endif endif endif

If uname -s returns "MINGW32_NT-*", we assume that we are using

the uname.exe in the MSYS toolkit.

ifeq (MINGW32_NT,$(findstring MINGW32_NT,$(OS_ARCH))) OS_RELEASE := $(patsubst MINGW32_NT-%,%,$(OS_ARCH)) OS_ARCH = WINNT USE_MSYS = 1 ifndef CPU_ARCH CPU_ARCH := $(shell uname -m) # # MSYS's uname -m returns "i686" on a Pentium Pro machine. # ifneq (,$(findstring 86,$(CPU_ARCH))) CPU_ARCH = x386 endif endif endif

ifeq ($(OS_TARGET),Android)

this should be configurable from the user

OS_TEST := arm OS_ARCH = Android ifndef OS_TARGET_RELEASE OS_TARGET_RELEASE := 8 endif endif

ifndef OS_TARGET ifeq ($(OS_ARCH), WINNT) OS_TARGET = WIN95 else OS_TARGET = $(OS_ARCH) endif endif

ifeq ($(OS_TARGET), WIN95) OS_RELEASE = 4.0 endif

ifdef OS_TARGET_RELEASE OS_RELEASE = $(OS_TARGET_RELEASE) endif

This variable is used to get OS_CONFIG.mk.

OS_CONFIG = $(OS_TARGET)$(OS_RELEASE)

OBJDIR_TAG depends on the predefined variable BUILD_OPT,

to distinguish between debug and release builds.

ifdef BUILD_OPT OBJDIR_TAG = $(64BIT_TAG)_OPT else ifdef BUILD_IDG OBJDIR_TAG = $(64BIT_TAG)_IDG else OBJDIR_TAG = $(64BIT_TAG)_DBG endif endif

The following flags are defined in the individual $(OS_CONFIG).mk

files.

CPU_TAG is defined if the CPU is not the most common CPU.

COMPILER_TAG is defined if the compiler is not the default compiler.

IMPL_STRATEGY may be defined too.

OBJDIR_NAME = $(OS_TARGET)$(OS_RELEASE)$(CPU_TAG)$(COMPILER_TAG)$(LIBC_TAG)$(IMPL_STRATEGY)$(OBJDIR_TAG).OBJ

ifeq (,$(filter-out WIN%,$(OS_TARGET))) ifndef BUILD_OPT

Define USE_DEBUG_RTL if you want to use the debug runtime library

(RTL) in the debug build

ifdef USE_DEBUG_RTL OBJDIR_NAME = $(OS_TARGET)$(OS_RELEASE)$(CPU_TAG)$(COMPILER_TAG)$(IMPL_STRATEGY)$(OBJDIR_TAG).OBJD endif endif endif

MK_ARCH = included
