Creating a Cross Compiler


To cross-compile, you need three packages
binutils (assembler, linker)
gcc (the compiler proper)
glibc or another libc implementation
As a minimal fallback, you can use "newlib"

The steps to build the compiler are:
compiling binutils
compiling the bootstrap gcc
compiling libc
compiling the final gcc (with C++, Java etc)


Most embedded distributions nowadays build the compiler first

Still, you can build your own, especially for uC targets
