Predefined macros,
Compilers usually provide different predefined macros for compiled programs based on different platforms and compilation options,
For example, Win32 win64 Linux, such as debug and release.
1. When using the GCC/g ++ compiler, you can run the following command to print the macros pre-compiled by the compiler.

contains only C compilers and public parts, while support packages for other languages such as "C + +, ADA, etc." need to be installed separately, which is why GCC is so powerful. "It relies on binutils and can refer to installing GCC"3. GLIBC: Contains the main C library, which provides basic routines for allocating memory, searching directories, reading and writing files, string processing, and so on. "T

Update Linux GCC to GCC 4.4.2
First need to prepare required materials: gcc4.4.2 version need to install gmp4.2.0 + and mpfr2.3.0 +, to the site of GMP (http://gmplib.org/fuse download gmp-4.3.1.tar.gz and MPRF sites (http://www.mpfr.org/fuse download mpfr-2.4.2.tar.gz)
1.Install GMP# Wget ftp://ftp.gmplib.org/pub/gmp-5.0.0/gmp-5.0.0.tar.bz2# Tar-zxvf gmp-4.3.2.
In the development of ARM-based embedded systems, there are usually two types of GCC tool chains that use cross-Compilation: Arm-Linux-* andArm-elf-*, the main difference between the two lies in the use of different C library files. Arm-Linux-* uses GNU glibc, while arm-elf-* generally usesUclibc/UC-libc or newlib. glibc, a C Library specially developed for embed
