51 # Compiler warnings you want to see
54 # Note that the kernel source you use to compile with should be the same as the
55 # Linux kernel you run your apps on. uClibc doesn't even try to achieve binary
56 # compatibility across kernel versions. So don't expect, for example, uClibc
57 # compiled with Linux kernel 2.0.x to implement lchown properly, since 2.0.x
58 # can't do that. Similarly, if you compile uClibc vs Linux 2.4.x kernel headers,
59 # but then run on Linux 2.0.x, lchown will be compiled into uClibc, but won't
60 # work at all. You have been warned.

63 # Set this to `false' if your CPU doesn't have a memory management unit (MMU).
64 # Set it to `true' otherwise.
67 # Set this to `false' if you don't have/need basic floating point support
68 # support in libc (strtod, printf, scanf). Set it to `true' otherwise.
69 # If this is not true, then libm will not be built.
70 HAS_FLOATING_POINT = true
72 # Set to `true' if you want the math library to contain the full set
73 # of C99 math library features. Costs an extra 35k or so on x86.
76 # Set this to `false' if you don't have/need "(unsigned) long long int" support.
77 # Set it to `true' otherwise.
78 # Affects *printf and *scanf functions.
79 # Also omits strto(u)ll, and (u)lltostr from the library if `false'.
82 # Set this to `false' if you don't have/need locale support; `true' otherwise.
83 # Note: Currently only affects the ctype functions. You must also generate
84 # a locale file for anything but the C locale. See directory extra/locale for
85 # a utility to do so. Also see the following option.
88 # Set this to the path of your uClibc locale file directory.

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

106 #MALLOC = malloc-930716
108 # If you want to collect common syscall code into one function, set to this to
109 # `true'. Set it to false otherwise.
110 # On i386 this saves about than 2.8k over all syscalls.
111 # The idea came from the implementation in dietlibc.
112 # At present, only affects i386.

115 # If you want large file summit support (greater then 2 Gib),
116 # turn this on. This has no effect unless your kernel supports
117 # lfs. This currently does nothing, but may someday...
120 # If you want to include RPC support, enable this. RPC is almost never used
121 # for anything except NFS support, so unless you plan to use NFS, leave this
122 # disabled. This is off by default.
125 # If you want to include support for the next version of the Internet
126 # Protocol: IP version 6, enable this. This is off by default.
