# Set the following to `true' to make a debuggable build, and `false' for
# production builds.
DODEBUG = false

# Compiler warnings you want to see 
WARNINGS=-Wall

# Enable support for shared libraries?
HAVE_SHARED = true

# Note that the kernel source you use to compile with should be the same as the
# Linux kernel you run your apps on.  uClibc doesn't even try to achieve binary
# compatibility across kernel versions.  So don't expect, for example, uClibc
# compiled with Linux kernel 2.0.x to implement lchown properly, since 2.0.x
# can't do that. Similarly, if you compile uClibc vs Linux 2.4.x kernel headers,
# but then run on Linux 2.0.x, lchown will be compiled into uClibc, but won't
# work at all.  You have been warned.
KERNEL_SOURCE=/usr/src/linux

# Set this to `false' if your CPU doesn't have a memory management unit (MMU).
# Set it to `true' otherwise.
HAS_MMU = true

# Set this to `false' if you don't have/need basic floating point support
# support in libc (strtod, printf, scanf).  Set it to `true' otherwise.
# Note: If not true, Rules.mak disables libm as well.
HAS_FLOATING_POINT = true

# Set this to `false' if you don't have/need float functions in libm.
# Set it to `true' otherwise, and make sure HAS_FLOATING_POINT is true as well.
HAS_LIBM_FLOAT = true

# Set this to `false' if you don't have/need double functions in libm.
# Set it to `true' otherwise, and make sure HAS_FLOATING_POINT is true as well.
HAS_LIBM_DOUBLE = true

# Set this to `false' if you don't have/need long double functions in libm.
# Set it to `true' otherwise, and make sure HAS_FLOATING_POINT is true as well.
HAS_LIBM_LONG_DOUBLE = false

# Set this to `false' if you don't have/need "(unsigned) long long int" support.
# Set it to `true' otherwise.
# Affects *printf and *scanf functions.
# Also omits strto(u)ll, and (u)lltostr from the library if `false'.
HAS_LONG_LONG = true

# Set this to `false' if you don't have/need locale support; `true' otherwise.
# Note: Currently only affects the ctype functions.  You must also generate
# a locale file for anything but the C locale.  See directory extra/locale for
# a utility to do so.  Also see the following option.
HAS_LOCALE = false

# Set this to the path of your uClibc locale file directory.
# Warning!  This must be different than the glibc locale directory to avoid
# name conflicts, as the locale files are entirely different in format!

# This specifies which malloc implementation is used.
# "malloc-simple" is very, very small, but is also very, very dumb 
# and does not try to make good use of memory or clean up after itself.
#
# "malloc" on the other hand is a bit bigger, but is pretty smart thereby
# minimizing memory wastage and reusing already allocated memory.  This 
# can be lots faster and safer IMHO.
#
# "malloc-930716" is from libc-5.3.12 and was/is the standard gnu malloc.
# It is actually smaller than "malloc", at least on i386.  Right now, it
# only works on i386 (and maybe m68k) because it needs sbrk.
#MALLOC = malloc-simple
MALLOC = malloc 
#MALLOC = malloc-930716

# If you want to collect common syscall code into one function, set to this to
# `true'.  Set it to false otherwise.
# On i386 this saves about than 2.8k over all syscalls.
# The idea came from the implementation in dietlibc.
# At present, only affects i386.
UNIFIED_SYSCALL = false

# If you want large file summit support (greater then 2 Gib), 
# turn this on.  This has no effect unless your kernel supports 
# lfs.  This currently does nothing, but may someday...
DOLFS = false

# If you want to include RPC support, enable this.  RPC is almost never used 
# for anything except NFS support, so unless you plan to use NFS, leave this
# disabled.  This is off by default.
INCLUDE_RPC = false

# If you want to include support for the next version of the Internet
# Protocol: IP version 6, enable this.  This is off by default.

DOPIC = false

# PREFIX is the directory prefix that is applied to all installed
# files.  Typically, it is set to /usr or /usr/local, although it could
# also be /opt/vendor_name_here/some/random/path/.  The install_runtime
# makefile target installs a few symbolic links based on PREFIX, not
# DEVEL_PREFIX.
#
# DEVEL_PREFIX is the directory where the development environment will
# be installed.  The uClibc header files are installed into
# $(DEVEL_PREFIX)/include, static libraries are installed into
# $(DEVEL_PREFIX)/lib, etc.  This directory is compiled into the uclibc
# cross compiler spoofer.  Generally, DEVEL_PREFIX should be set to
# the same thing as $(PREFIX).  DEVEL_PREFIX is used by the Makefile install 
# targets install_gcc, install_dev, and install_runtime.
#
# TARGET_PREFIX is the directory into which the target runtime
# environment is installed.  The target runtime environment is what one
# would use for a embedded system where uclibc is the native libaray.
# This will typically be a staging area for creating a root filesystem
# for the target system, so the default is in the local directory.
# 
# If you want to install to a temporary directory before copying files
# to their final location, define DESTDIR during the install step,
# i.e., 'make install DESTDIR=/home/foo/uclibc/_install'.
