Re: Help: How to determine big/little endian?

The problem with this approach is that it works fine for situations
where the output of the compiler is directly runable. If you use a
cross compiler, you have to run the test program on the target. For
example, in my current job, I develop big endian PowerPC compilers
(GCC) on Linux running on a little endian Pentium. In fact, when you
get to the embedded world, it is often times the case that the target
doesn't run an OS (or you have to down load it via a serial line or
flash EPROM).
