安裝步驟程式碼：

1.Install Clang and libc++, run:
sudo apt-get update
sudo apt-get install -y build-essential autoconf automake libtool curl make g++ unzip pkg-config wget clang-3.9

輸入命令過程中可能會出現以下錯誤：E: 無法獲得鎖 /var/lib/dpkg/lock-frontend - open (11: 資源暫時不可用)；解決方法：參考連線

sudo update-alternatives --install /usr/bin/clang clang /usr/bin/clang-3.9 1
sudo update-alternatives --install /usr/bin/clang++ clang++ /usr/bin/clang++-3.9 1
sudo apt-get install -y libc++-dev libc++abi-dev libtbb-dev

2.安裝cmake

wget https://cmake.org/files/v3.9/cmake-3.9.4-Linux-x86_64.tar.gz
tar xvzf cmake-3.9.4-Linux-x86_64.tar.gz
sudo mv cmake-3.9.4-Linux-x86_64 /usr/bin/cmake
export PATH=$PATH:/usr/bin/cmake/bin
rm cmake-3.9.4-Linux-x86_64.tar.gz
 

3.Install protobuf: after cloning the protobuf repo, run:

sudo apt-get install autoconf automake libtool curl make g++ unzip
git clone https://github.com/google/protobuf.git
cd protobuf
git submodule update --init --recursive
./autogen.sh
./configure CXX=clang++ CXXFLAGS='-std=c++11 -stdlib=libc++ -O3 -g'
make
make check
sudo make install
ldconfig
 

這裡的安裝問題可參考這裡

4.Build KVS, run:

git clone https://github.com/ucbrise/anna.git
cd anna
bash scripts/build_release.sh
(This command will build a KVS that provides last-writer-win consistency. Lattice composition for other consistency levels can be found in kvs/include)

出現了這個問題：

CMakeFiles/Makefile2:423: recipe for target 'kvs/CMakeFiles/kvs_server.dir/all' failed
make[1]: *** [kvs/CMakeFiles/kvs_server.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2

解決方法如下：

1. open file vendor/tbb/CMakeLists.txt
2. for the last two cmake 'set' cmd in this file, which are using fixed value 'linux_intel64_clang_cc4.8_libc2.19_kernel3.13.0_release'. This is what you got in your error msg, and also the reason why you got this error msg.
3. change this value to be the same as your env. For example, I am using clang 5.4.0, libc 2.23, kernel 4.4.0 , so I changed this value to 'linux_intel64_clang_cc5.4.0_libc2.23_kernel4.4.0_release' .

Tips: If you can't make sure what this value in your env should be, you can just run 'scripts/build_release.sh' for once. Yeah, the build will fail, but then you can check the generated folder by the build process, which is 'build/vendor/tbb/src/tbb/build'. Under this folder, you will find a sub folder, its name is just the value you need.(在anna檔案下有相關的配置屬性)

解決掉一個問題，又出現了一個問題：

clang: error: linker command failed with exit code 1 (use -v to see invocation)
kvs/CMakeFiles/kvs_server.dir/build.make:181: recipe for target 'kvs/kvs_server' failed
make[2]: *** [kvs/kvs_server] Error 1
CMakeFiles/Makefile2:423: recipe for target 'kvs/CMakeFiles/kvs_server.dir/all' failed
make[1]: *** [kvs/CMakeFiles/kvs_server.dir/all] Error 2
Makefile:83: recipe for target 'all' failed
make: *** [all] Error 2
解決方法：重新安裝protobuf，沒有安裝正確。

執行：bash scripts/build_release.sh

提示：scripts/build_debug.sh: 行 4: cmake: 未找到命令
make: *** 沒有指明目標並且找不到 makefile。 停止。

這個原因是環境變數沒有配置。

解決方法：可以使用臨時環境變數export PATH=$PATH:/usr/bin/cmake/bin

或者將環境變數寫入檔案中。

程式碼如下：

vim ~/.bashrc

新增環境變數

source ~/.bashrc
