# ChinOS

#### 介绍
ChinOS是为了研究SeL4微内核自己魔改的微内核操作系统，仅供学习使用。

#### 构建环境
* 主机：Ubuntu18.04LTS
* 编译器：ARM-GCC
* 编译工具：GN + Ninja
* 内核配置工具：Kconfig(menuconfig)

#### 软件架构
软件架构说明


#### 编译流程

* ./configure.sh sun8iw11p
* make menuconfig
* make

固件最后生成在out/image/文件夹里

#### 环境构建
##### Ninja构建
安装依赖
```shell
sudo apt install re2c
re2c --version
```

下载Ninja
```shell
git clone https://github.com/ninja-build/ninja.git
```

编译安装

```shell
./configure.py --bootstrap
sudo cp ninja /usr/bin
ninja --version
```

##### GN构建
安装依赖
```shell
sudo apt-get install clang-7
```

修改软连接
```shell
cd /usr/bin
sudo ln -s clang-7 clang
sudo ln -s clang++-7 clang++
sudo ln -s clang-cpp-7 clang-cpp
clang++ --version
```
下载GN
```shell
git clone https://github.com/timniederhausen/gn.git
```

编译安装
```shell
./build/gen.py
ninja -C out
sudo cp ./out/gn /usr/bin
gn --version
```

##### Kconfig构建
依赖安装
```shell
sudo apt install \
bison flex gettext texinfo libncurses5-dev libncursesw5-dev \
gperf automake libtool pkg-config build-essential gperf genromfs \
libgmp-dev libmpc-dev libmpfr-dev libisl-dev binutils-dev libelf-dev \
libexpat-dev gcc-multilib g++-multilib picocom u-boot-tools util-linux
```

下载Kconfig
```shell
git clone https://bitbucket.org/nuttx/tools.git
```

编译安装
```shell
cd tools/kconfig-frontends
./configure --enable-mconf --disable-nconf --disable-gconf --disable-qconf
make
# make isntall must use sudo
sudo make isntall
```

添加环境变量
```shell
vim ~/.bashrc
export LD_LIBRARY_PATH=/usr/local/lib:$LD_LIBRARY_PATH
source ~/.bashrc
```
##### Toolchain构建
编译链下载
```shell
# Download url
https://developer.arm.com/tools-and-software/open-source-software/developer-tools/gnu-toolchain/gnu-rm/downloads
# Linux x86_64 Tarball
gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2
```
编译链安装
```shell
tar xvf gcc-arm-none-eabi-10.3-2021.10-x86_64-linux.tar.bz2
```
添加环境变量
