/gocore

A go kernel

Primary LanguageGo

Gocore

setup

To compile gocore You need a gccgo cross-compiler

  1. build a target i386/i686 gcc cross-compiler with go enabled, follow the article http://wiki.osdev.org/GCC_Cross-Compiler

  2. install nasm from your repositories

  3. install qemu for test

compiler & run!

  1. compile: make GCC=i686-elf-gcc GCCGO=i686-elf-gccgo, replace GCC and GCCGO with your binary name

  2. run on qemu: make run-qemu QEMU=qemu-system-i386, replace QEMU with your target binary name

交叉编译

https://wiki.osdev.org/GCC_Cross-Compiler https://wiki.osdev.org/Go_Bare_Bones

我用的binutils-2.34和gcc-7.5.0，按照教程走就可以了，除了gcc configure这一步改成

../gcc-x.y.z/configure --target=$TARGET --prefix="$PREFIX" --disable-nls --enable-languages=c,c++,go --without-headers

源码安装高版本gcc如9.3.0时，可能会发生错误: gcc configure: error: Building GCC requires GMP 4.2+, MPFR 2.3.1+ and MPC 0.8.0+ 解决方法: 在gcc源码目录下, ./contrib/download_prerequisites, 会自动下载相关依赖.
