NATIVE_CC = gcc CROSS = #i386-linux- CC = $(CROSS)gcc AR = $(CROSS)ar LD = $(CROSS)ld NM = $(CROSS)nm STRIPTOOL = $(CROSS)strip #STRIPTOOL = /bin/true # 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 # 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 = false # 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. # 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! LOCALE_DIR = "/usr/share/uClibc-locale/" # 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'.

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 # ROOT_DIR is the base directory which will be compiled into the uClibc # runtime environment.
