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.

# 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.

# 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 = false
# Set this to `false' if you don't have/need long double functions in libm.

HAS_LIBM_LONG_DOUBLE = false
# Set this to `false' if you don't have/need "(unsigned) long long int" support.

# 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.

# turn this on. This has no effect unless your kernel supports
# lfs. This currently does nothing, but may someday...

# for anything except NFS support, so unless you plan to use NFS, leave this
# disabled. This is off by default.

# ROOT_DIR is the base directory which will be compiled into the uClibc
# runtime environment. When compiled as a shared library, the shared
# library loader will look in <ROOT_DIR>/lib and <ROOT_DIR>/usr/lib
# for shared libraries.
#
# DEVEL_PREFIX is the base directory which will be compiled into the uClibc
# development environment. The uClibc development environment will
# look for the uClibc header files under <DEVEL_PREFIX><ROOT_DIR>/usr/include,
# and for static libs and crt0.o in <DEVEL_PREFIX><ROOT_DIR>/usr/lib.
# Also, 'make install' will install the compiler tools to
# <DEVEL_PREFIX><ROOT_DIR>/bin and <DEVEL_PREFIX><ROOT_DIR>/usr/bin.
#
# TARGET_PREFIX is the directory under which 'make install' will install the
# uClibc runtime environment. This path does not get compiled into anything,
# and is provided simply to make it easier to build standalone target systems.
# Note: This doesn't do anything if there are no shared libs.
