- 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.
