ubuntu24.04编译GCC

GCC基础设施

获取GCC的依赖组件

ftp://gcc.gnu.org/pub/gcc/infrastructure/

1. 下载文件到你想要的目录~/Downloads，或者/tmp/gcc。
2. 用静态库来配置make脚本。

$ ./configure --disable-shared --enable-static --prefix=/tmp/gcc

--disable-shared这个选项值得走进看看。如果需要纯粹的二进制执行包，不依赖于任何动态库，这个选项就是你所需要的。

Versions

确认这些依赖库的版本，就是编译的GCC所要求的。怎么看？那就直接跑configure里面会有提醒。

GMP

GNU Multiple Percision Arithmetric Library

$ wget ftp://gcc.gnu.org/pub/gcc/infrastructure/gmp-4.3.2.tar.bz2
$ bunzip2 gmp-4.3.2.tar.bz2
$ tar xvf gmp-4.3.2.tar
$ cd gmp-4.3.2
$ ./configure --disable-shared --enable-static --prefix=/tmp/gcc
$ make && make check && make install

MPFR

GNU Multiple-precision floating-point rounding library. 依赖GMP.

$ wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpfr-2.4.2.tar.bz2
$ bunzip2 mpfr-2.4.2.tar.bz2
$ tar xvf mpfr-2.4.2.tar
$ cd mpfr-2.4.2
$ ./configure --disable-shared --enable-static --prefix=/tmp/gcc --with-gmp=/tmp/gcc
$ make && make check && make install

MPC

GNU Multiple-precision C library. 依赖于GMP和MPFR.

wget ftp://gcc.gnu.org/pub/gcc/infrastructure/mpc-0.8.1.tar.gz
tar zxvf mpc-0.8.1.tar.gz
cd mpc-0.8.1
./configure --disable-shared --enable-static --prefix=/tmp/gcc --with-gmp=/tmp/gcc --with-mpfr=/tmp/gcc
make && make check && make install

ELF

ELF stands for Executable and Linkable Format. This library provides architecture-independent size and endian support.

wget http://www.mr511.de/software/libelf-0.8.13.tar.gz
tar zxvf libelf-0.8.13.tar.gz
cd libelf-0.8.13
./configure --disable-shared --enable-static --prefix=/tmp/gcc
make && make check && make install
