Build GCC

Posted on Edited on In ,

Today, let's try to build the MOST RECENT GCC 9.1. We strictly follow the TERRIFIC blog How to Build a GCC Cross-Compiler with trivial modifications for my x86_64 desktop instead of aarch64 cross compile.

Preparations

Packages Required on HOST

Some packages are required to install on the host computer, including: * g++ * make * gawk * bison * flex * expect * gnat etc.

Get ALL Packages for Building GCC

A wget-list.txt file is provided to download ALL required packages up-to-date. After having downloaded this single text file, the UNIQUE command to download all files is as follows:

1
➜  gcc ✗ wget -i wget-list.txt

You can of course download the files one by one. All concerned files are listed below: * https://gnu.freemirror.org/gnu/binutils/binutils-2.32.tar.gz * https://gnu.freemirror.org/gnu//gcc/gcc-9.1.0/gcc-9.1.0.tar.gz * https://mirrors.edge.kernel.org/pub/linux/kernel/v5.x/linux-5.1.12.tar.gz * https://ftp.gnu.org/glibc/glibc-2.29.tar.xz * https://ftp.gnu.org/mpfr/mpfr-4.0.2.tar.xz * https://ftp.gnu.org/gmp/gmp-6.1.2.tar.xz * https://ftp.gnu.org/mpc/mpc-1.1.0.tar.gz * ftp://gcc.gnu.org/pub/gcc/infrastructure/isl-0.18.tar.bz2 * ftp://gcc.gnu.org/pub/gcc/infrastructure/cloog-0.18.1.tar.gz

Then, we extract all .tar files in whatever way you prefer.

➜  gcc mkdir -p /opt/native
