## 一、Taichi编译环境搭建 ##

### 1.1、软件要求： ###

以下是在虚拟机中安装Ubuntu的步骤。

下载虚拟机软件VirtualBox：https://www.virtualbox.org/

下载Ubuntu系统（中科大镜像站）：https://mirrors.ustc.edu.cn/ 版本：20.04（amd64, desktop LiveCD）

### 1.2、安装虚拟机就是按照步骤来就行 ###

### 1.3、安装Ubuntu也是按照步骤来就行 ###

### 1.4、更换清华镜像： ###

更改etc/apt/sources.list文件： `sudo gedit sources.list`

在\[https://mirrors.tuna.tsinghu a.edu.cn/help/ubuntu/\](https://mirrors.tuna.tsinghu a.edu.cn/help/ubuntu/)中根据Ubuntu的不同版本添加不同配置

20.04版本如下：

# 默认注释了源码镜像以提高 apt update 速度，如有需要可自行取消注释
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
    # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal main restricted universe multiverse
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
    # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-updates main restricted universe multiverse
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
    # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-backports main restricted universe multiverse
    deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
    # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-security main restricted universe multiverse
    
    # 预发布软件源，不建议启用
    # deb https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse
    # deb-src https://mirrors.tuna.tsinghua.edu.cn/ubuntu/ focal-proposed main restricted universe multiverse

更改配置后需要更新：`sudo apt-get update`

### 2、Taichi基础环境配置 ###

#### 2.1、Python以及Python依赖的安装 ####

python3 -m pip install --user setuptools astpretty astor pybind11 Pillow dill 
    python3 -m pip install --user pytest pytest-rerunfailures pytest-xdist yapf 
    python3 -m pip install --user numpy GitPython coverage colorama autograd

#### 2.2、安装并更换编译器为clang（version>7） ####

#安裝
    sudo apt install libtinfo-dev clang-81
    #更改編譯器
    sudo update-alternatives --config c++ 
    sudo update-alternatives --config cc

#### 2.3、构建LLVM ####

#下载LLVM文件 
    wget https://github.com/llvm/llvm-project/releases/download/llvmorg10.0.0/llvm-10.0.0.src.tar.xz 
    #解压 
    tar xvJf llvm-10.0.0.src.tar.xz
    cd llvm-10.0.0.src 
    #新建build文件夹 
    mkdir build 
    cd build
    cmake .. -DLLVM_ENABLE_RTTI:BOOL=ON -DBUILD_SHARED_LIBS:BOOL=OFF DCMAKE_BUILD_TYPE=Release -DLLVM_TARGETS_TO_BUILD="X86;NVPTX" DLLVM_ENABLE_ASSERTIONS=ON 
    # If you are building on NVIDIA Jetson TX2, use DLLVM_TARGETS_TO_BUILD="ARM;NVPTX"
    make -j 8  (构建时长大约为30分钟)
    sudo make install
    # Check your LLVM installation 
    llvm-config --version  
    # You should get 10.0.0

### 3、开发者配置 ###

#### 3.1、给配置文件末尾添加Taichi路径（vim ~/.bashrc） ####

// 下载Taichi源码存放的位置 
    export TAICHI_REPO_DIR=/path/to/taichi  
    # Path to your taichi repository 
    export PYTHONPATH=$TAICHI_REPO_DIR/python:$PYTHONPATH 
    export PATH=$TAICHI_REPO_DIR/bin:$PATH 
    # export CXX=/path/to/clang 
    # Uncomment if you encounter issue about compiler in the next step. 
    # export PATH=/opt/llvm/bin:$PATH 
    # Uncomment if your llvm or clang is installed in /opt

#### 3.2、加载配置文件 ####

source ~/.bashrc

#### 3.3、编译Taichi,在build文件夹下执行’‘python3 -m taichi test’’（约5分钟） ####

git clone https://github.com/taichi-dev/taichi --depth=1 --branch=master 
    #Taichi源码存放的位置要与.bashrc指定的位置相同 
    cd taichi 
    git submodule update --init --recursive --depth=1   # 必不可少
    mkdir build 
    cd build 
    cmake .. 
    # On Linux / OS X, if you do not set clang as the default compiler 
    # use the line below: 
    # cmake .. -DCMAKE_CXX_COMPILER=clang 
    # 
    # Alternatively, if you would like to set clang as the default compiler # On Unix CMake honors environment variables $CC and $CXX upon deciding which C and C++ compilers to use 
    
    make -j 8     
    
    #修改源码后需要重新cmake、make即可生效，至此Taichi的编译环境安装成功。
