1. Download gcc suitable version from the website, http://gcc.gnu.org, Since it does not support 4.5 and above, I chose the highest version of the 4.4.6 4.5, gcc-4.4.6.tar.gz and gcc-4.4.6.tar.bz2 two kinds of bags, according to personal preference of the first;
2. Unpack #tar ZXFV gcc-4.4.6
In ARM-based embedded system development, there are two GCC tool chains that often use cross-Compilation:The main difference between ARM-Linux-* and arm-elf-* is that they use different C-library files. Arm-Linux-* useWhile arm-elf-* generally uses uclibc/UC-libc or RedHat for embedded systems.Newlib. glibc. Both uclibc, UC-libc, and newlib are C language library files.Glibc is developed for PC, and uclibc/UC-libc is a small size compatible with glibc

Preface
GCC (GNU Compiler Collection, GNU Compiler Collection) is an open-source project on Linux and other UNIX-like platforms, software development and other essential tool chains (other members of the tool chain include binutils, glibc, libstdc ++, etc)
In addition, programmers and System Administrators often need to manually compile and install the software source code, whether it is a configure script or make tool/MAKEFILE file, in the end,
