Common scripts to build BiscuitOS

BiscuitOS

BiscuitOS is a Linux-Distro that base on legacy or newest Linux kernel (such as Linux 0.11, 1.x, 2.x, 3.x, 4.x, 5.x 6.x and more). BiscuitOS is an open and free operating system that developers can use under the GNU General Public License.

The target of BiscuitOS is to create an operating system debugging and running environment that makes developers focus on CODE and doesn't waste time on how to build or port an operating system to different hardware.

This project is named BiscuitOS that is a specific builtroot for BiscuitOS. All developers can configure various kernel/rootfs features and create a full harddisk-image. The BiscuitOS works on Intel-x86 family CPU (such as i386, i486 ...)/ ARM32 or ARM64, and the project offers an emulate to run BiscuitOS without hardware. So, don't stop, and play Linux with BiscuitOS.

1. To Prepare

At first, Install basic toolchain, such as Ubuntu or Centos:

# Ubuntu/Debian
sudo apt-get update
sudo apt-get install git make figlet gawk flex bison
# CentOS
yum update
# ArchLinux

2. Donwload Project

Download BiscuitOS Source Code from Github/Gitee:

git clone https://github.com/BiscuitOS/BiscuitOS.git --depth=1
or
git clone https://gitee.com/BiscuitOS_team/BiscuitOS.git --depth=1

And then change direct into BiscuitOS, install full toolchains:

make defconfig
make install

3. To Start

Simple to Start BiscuitOS, e.g. linux 0.11:

cd */BiscuitOS
make linux-0.11_defconfig
make

Then, Output README.md information, See README.md and follow command to build, e.g.

编译到最后报错 EXT4 是什么意思

/home/weiling/BiscuitOS/scripts/fs/rootfs.sh: 行 450: figlet：未找到命令
make: *** [/home/weiling/BiscuitOS/fs/ext4/Makefile:34：/home/weiling/BiscuitOS/fs/ext4/build] 错误 127

运行Linux0.12的时候，虚拟机会反复重启

编译正常，运行make start命令后，虚拟机反复重启，但是Linux0.11就没有这个问题，很正常

BiscuitOS 博客图片无法显示

很多小伙伴都反馈使用手机或者网页的时候，打开 BiscuitOS 博客图片显示不了，如下图：

BiscuitOS 博客的图片基于 Gitee 构建，Gitee 对图片的引用有限制，当图片的大小超过一定体积之后，只有登陆了 Gitee 才能看到图片，因此为了解决这个问题，有 Gitee 的小伙伴可以在手机浏览器起登陆 Gitee，如果没有的 Gitee 的小伙伴需要注册一个 Gitee 账号并登陆。

由于这个问题目前只有这个解法，给大家带来不便请谅解。

git clone之后第一步make出错

[RISCV32] Fail to make linux-5.6-riscv32_defconfig

make x86_64 可以工作

但是 make riscv32 报 工具链不存在

test website

【编译错误】mount: /opt/BiscuitOS/output/linux-5.0-x86_64/rootfs/tmpfs/: mount failed: Operation not permitted.

【背景】

为了方便开发环境能够在不同机器上进行实验，希望使用dock搭建开发环境，提升跨平台性.

【问题】

使用dockerfile搭建编译环境后按照 BiscuitOS Linux 5.0 x86_64 Usermanual来编译，出现mount: /opt/BiscuitOS/output/linux-5.0-x86_64/rootfs/tmpfs/: mount failed: Operation not permitted.

【复现步骤】

docker build -t BiscuitOS:1.0 -f Dockerfile.cpp-env-ubuntu .
docker run -it -v /data/BiscuitOs/opt/BiscuitOs BiscuitOS:1.0  /bin/bash
cd BiscuitOS
make linux-5.0-x86_64_defconfig

uboot的gdb环境

Hi， @BuddyZhang1 ，BiscuitOS项目太棒了。

能否增加uboot的gdb环境，感谢！

When compiling a 32 core machine, -j4 in the script can be replaced with -j$(nproc) to provide compilation speed.

which you can try

Ubuntu 20.04 如何支持 BiscuitOS

有不少小伙伴将 Ubuntu 升级到 Ubuntu 20.04，但发现在部署 BiscuitOS 时发现 qemu 编译出错。面对这个问题，小伙伴们只需修改 qemu 的版本即可。具体做法有好几种，效果版自行参考：

方法零

2022-06 BiscuitOS 开始对 Ubuntu 22/20 进行了适配，因此可以参考 BiscuitOS 源码目录下的 README

方法 一

例如你使用 BiscuitOS 部署一个 linux 5.0 的 x86_64 开发环境，那么你会从 BiscuitOS/configs/linux-5.0-x86_64_defconfig, 此时只需修改 linux-5.0-x86_64_defconfig 里面的 CONFIG_QEMU_SYSTEM_VERSION="", 修改为 "5.0.0"， 然后重新执行如下命令部署：

cd BiscuitOS/
make linux-5.0-x86_64_defconfig
make

方法 二

可以通过 make menuconfig 进行配置，在 BiscuitOS 目录下执行如下命令：

cd BiscuitOS/
make linux-5.0-x86_64_defconfig
make menuconfig

     [*] Package  --->
          [*]   qemu-system  --->
                 (5.0.0) qemu-system verstion

make

方法 san

直接修改 ".config" 文件，该文件位于 BiscuitOS 目录下，修改该文件里面的 CONFIG_QEMU_SYSTEM_VERSION="", 修改为 "5.0.0"， 然后重新执行如下命令部署：

cd BiscuitOS/
vi .config
make
