2.根据官网教程,编译gcc的所需环境依赖m4,gmp,mfpr,mpc

GNU Multiple Precision Library (GMP) version 4.3.2 (or later)
Necessary to build GCC. If a GMP source distribution is found in a subdirectory of your GCC sources named gmp, it will be built together with GCC. Alternatively, if GMP is already installed but it is not in your library search path, you will have to configure with the--with-gmp configure option. See also --with-gmp-liband --with-gmp-include.
MPFR Library version 2.4.2 (or later)
Necessary to build GCC. It can be downloaded fromhttp://www.mpfr.org/. If an MPFR source distribution is found in a subdirectory of your GCC sources named mpfr, it will be built together with GCC. Alternatively, if MPFR is already installed but it is not in your default library search path, the--with-mpfr configure option should be used. See also--with-mpfr-lib and --with-mpfr-include.
MPC Library version 0.8.1 (or later)
Necessary to build GCC. It can be downloaded fromhttp://www.multiprecision.org/. If an MPC source distribution is found in a subdirectory of your GCC sources named mpc, it will be built together with GCC. Alternatively, if MPC is already installed but it is not in your default library search path, the--with-mpc configure option should be used. See also--with-mpc-lib and --with-mpc-include.
