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.

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.

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.
