MikanOSのビルド手順を復習
この一連の手順を自動化する
6
ブートローダのビルドをシェルスクリプト化（build_boot_loader.sh）
7
#!/bin/bash
source edksetup.sh
cd Conf
sed -i "s/^ACTIVE_PLATFORM[\t ]*=[\t ]*.*$/ACTIVE_PLATFORM = MikanLoaderPkg\/MikanLoaderPkg.dsc/" target.txt
sed -i "s/^TARGET[\t ]*=[\t ]*.*$/TARGET = DEBUG/" target.txt
sed -i "s/^TARGET_ARCH[\t ]*=[\t ]*.*$/TARGET_ARCH = X64/" target.txt
sed -i "s/^TOOL_CHAIN_TAG[\t ]*=[\t ]*.*$/TOOL_CHAIN_TAG = CLANG38/" target.txt
build
MikanOS本体のビルドをシェルスクリプト化（build_mikanos.sh）
8
#!/bin/bash
source ../osbook/devenv/buildenv.sh
./build.sh
ビルドのための環境構築部分も自動化したい

Dockerを使おう！

ENV DEBIAN_FRONTEND=noninteractive
RUN apt update
RUN apt upgrade -y
RUN apt install -y ansible

makeでビルドできるようにする
