运行环境安装

环境要求

Requirements
- GCC 5 or later (tested with up to 11) or LLVM/clang 5 or later (tested with up to 12). We recommend clang because it performs better.
- MPIR library, compiled with C++ support (use flag --enable-cxx when running configure). You can use make -j8 tldr to install it locally.
- libsodium library, tested against 1.0.18
- OpenSSL, tested against 1.1.1
- Boost.Asio with SSL support (libboost-dev on Ubuntu), tested against 1.71
- Boost.Thread for BMR (libboost-thread-dev on Ubuntu), tested against 1.71
- x86 or ARM 64-bit CPU (the latter tested with AWS Gravitron and Apple Silicon)
- Python 3.5 or later
- NTL library for homomorphic encryption (optional; tested with NTL 10.5)

python 3.5+ 安装，本地安装的是 python3.7（和本地虚拟机对应）

// requirements
sudo dnf install -y gcc openssl-devel bzip2-devel libffi-devel

// install python
cd /opt
sudo wget https://www.python.org/ftp/python/3.7.9/Python-3.7.12.tgz
sudo tar xzf Python-3.7.12.tgz
cd Python-3.7.12
sudo ./configure --enable-optimizations
sudo make altinstall
sudo rm Python-3.7.12.tgz

// 建立python软连接
ll /usr/local/bin | grep python
sudo ln -s /usr/local/bin/python3.7 /usr/bin/python
sudo ln -s /usr/local/bin/python3.7 /usr/bin/python3
// 如果python3存在，则删除python3，再重新进行软连接
sudo rm /usr/bin/python3

GCC安装，此处安装的是clang

参考：How To Install clang on CentOS 8

sudo dnf makecache --refresh
sudo dnf -y install clang

解决方法参考：centos8 yum替换阿里源

libtool安装

sudo dnf makecache
sudo dnf install -y libtool.x86_64

yasm安装

cd /opt
sudo wget http://www.tortall.net/projects/yasm/releases/yasm-1.3.0.tar.gz
sudo tar zxvf yasm-1.3.0.tar.gz
cd yasm-1.3.0
sudo ./configure
sudo make install 
cd .. && sudo rm yasm-1.3.0.tar.gz

libsodium library 安装

sudo dnf install -y libsodium-static.x86_64

OpenSSL 安装

// 查看是否已安装，由于本地已安装OpenSSL 1.1.1k ，跳过此步骤
openssl version -v

// Install C_rehash script
sudo yum install -y openssl-perl

Boost.Asio with SSL support, Boost.Thread for BMR 安装

截至到2022.7.7，centos8 最新版本是1.66

sudo dnf -y install boost

// 安装 boost.asio库，参考https://blog.csdn.net/qq_28648083/article/details/53465367

// 其下载地址：https://sourceforge.net/projects/boost/files/boost
// 打开F12，使用network选项卡，获得.tar.gz的下载地址
cd /opt
sudo wget https://jaist.dl.sourceforge.net/project/boost/boost/1.79.0/boost_1_79_0.tar.gz
sudo tar -zxvf  boost_1_79_0.tar.gz 
cd boost_1_79_0
sudo ./bootstrap.sh
sudo ./b2 install

安装好之后，仍然找不到头文件

sudo vi /etc/ld.so.conf.d/boost.asio.1.79.conf
// 输入如下字符串，保存退出
/usr/local/lib

// 使修改生效
sudo ldconfig

NTL 安装

install requirements

sudo dnf makecache --refresh

// 查看文件是否被删除干净
find ./ -type f | grep \\.o$
find ./ -type f | grep \\.so$
find ./ -type f | grep \\.x$
find ./ -type f | grep \\.d$
find ./ -type f | grep \\.a$
// 编译
make -j8 tldr 

如果出现./configure: Permission denied错误，设置可执行权限

chmod +x mpir/*.sh
chmod +x mpir/configure

如果出现../libtool: line 1766: ../mpn/m4-ccas: Permission denied错误，设置可执行权限

chmod +x mpir/mpn/m4-ccas

问题汇总

当python（指向python3.7.12）和python3（指向python3.6.8）版本不一致时就会出现如下问题，到最后呈现都没法运行。所以，出现问题时，一定要检查python、python3的版本。同时执行make clean删除历史。

使用mascot-party虚拟机出现的错误

libsodium.18.so找不到错误

具体错误如下：

./mascot-party.x: error while loading shared libraries: libSPDZ.so: cannot open shared object file: No such file or directory

使用ldd mascot-party.x查看 mascot-party.x引用的链接库信息如下：

通过对比，有如下几个库是重复、多余且找不到的：

        libsodium.so.18 => not found
        libboost_system.so.1.58.0 => not found
        libssl.so.1.0.0 => not found
        libcrypto.so.1.0.0 => not found

最终解决，发现make clean无法删除./local/lib目录下的libmpir.so,libmpirxx.so,libSPDZ.so文件，删除之后重新编译即可正常运行。

make clean
rm ./local/lib/*

libSPDZ.so找不到错误

重新编译一下：

make clean
rm CONFIG.mine
make -j 8 tldr

解决方法：

参考：https://ubuntuforums.org/showthread.php?t=2393181

As the error messages say, you need to try adding -fPIC to the C compiler flags and/or C++ compiler flags. If that does not work, try instead adding -fno-PIE -no-pie to the C compiler flags and C++ compiler flags.

How to do this will depend on the specific software.

删除旧文件

make clean
// mpir清除旧文件
cd mpir && make clean && cd ..
rm ./local/* -rf

// 查看文件是否被删除干净
find ./ -type f | grep \\.o$
find ./ -type f | grep \\.so$
find ./ -type f | grep \\.x$
find ./ -type f | grep \\.d$
find ./ -type f | grep \\.a$
// 如果有未删除干净的文件，则执行如下方法删除
find ./ -type f | grep \\.o$ | xargs rm -rf
find ./ -type f | grep \\.so$ | xargs rm -rf
find ./ -type f | grep \\.x$ | xargs rm -rf
find ./ -type f | grep \\.d$ | xargs rm -rf
find ./ -type f | grep \\.a$ | xargs rm -rf

如果还是不成功，则在Makefile文件的CFLAGS后增加 -fno-PIE -no-pie ，如下所示：

...
CFLAGS += -fPIC -fno-PIE -no-pie
...

另外，tldr、semi-party.x的库与hemi-party.x的库不一致，如果要编译hemi-party.x的库，就需要clean一下。
