# Compiler warnings you want to see
WARNINGS=-Wall
# 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.

# 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.
# If this is not true, then libm will not be built.

# of C99 math library features. Costs an extra 35k or so on x86.

# Set this to `false' if you don't have/need locale support; `true' otherwise.
# NOTE: Currently does not affect collation.
# You must also generate the locale data and associated .h file.

# This specifies which malloc implementation is used.
#
# "malloc" use mmap for all allocations and so works very well on MMU-less
# systems that do not support the brk() system call. It is pretty smart
# about reusing already allocated memory, and minimizing memory wastage.
#
# "malloc-930716" is derived from libc-5.3.12 and uses the brk() system call
# for all memory allocations. This makes it very fast. It is also pretty

# Because this uses brk() it will not work on uClinux MMU-less systems.
