我使用的是 WSL 子系统，

• 操作系统版本：Ubuntu 22.04.2 LTS，位数 x86_64
• GMP 版本：6.2.1
• NTL 版本：11.5.1

安装 GMP

下载 GMP 6.2.1 版本（必须和 NTL 11.5.1 匹配，如果冲突报错了，在你安装的源码目录 gmp-6.3.0 下执行 sudo make uninstall 卸载），解压并进入 gmp-6.2.1 文件夹，

./configure --prefix=$HOME/gmpmakemake checksudo make install

如果 prefix 不指定安装的目录，库文件 lib 会产生在 /usr/local/lib，头文件在 /usr/local/include。我没有指定，让它默认安装到 /usr/local 内。

安装结果：

----------------------------------------------------------------------
Libraries have been installed in:/usr/local/libIf you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:- add LIBDIR to the 'LD_LIBRARY_PATH' environment variableduring execution- add LIBDIR to the 'LD_RUN_PATH' environment variableduring linking- use the '-Wl,-rpath -Wl,LIBDIR' linker flag- have your system administrator add LIBDIR to '/etc/ld.so.conf'See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

make  install-data-hook
make[4]: Entering directory '/mnt/e/ThirdPartyLibrary/GMP/gmp-6.2.1'

安装 gf2x

如果源码文件夹下没有 ./configure，但有 configure.am 或 configure.in，我们用 autoconf 命令来生成。

1. 我们先安装 autoconf 工具，

   sudo apt-get install autoconf
   

2. 下载 gf2x，我们下载 .tar.gz 版本的压缩文件，并在 Linux 下解压（在 Windows 下解压 .zip 做编译时会报错，因为 Linux 下的软链接被翻译成了形如 ../../crypto/opensslconf.h 的一行代码形式），

   gunzip gf2x-master.tar.gztar xf gf2x-master.tarcd gf2x-master
   

3. 我们先执行如下指令（直接执行 autoreconf --install 和 ./configure 会有找不到 Makefile.in 文件的报错），

   aclocallibtoolize --forceautomake --add-missingautoconf
   

4. 然后生成 ./configure 文件，

   autoreconf --install
   

5. 现在可以安装 gf2x 了，

   ./configuremakemake checksudo make install
   

安装结果：

Libraries have been installed in:/home/wqf/sw/libIf you ever happen to want to link against installed libraries
in a given directory, LIBDIR, you must either use libtool, and
specify the full pathname of the library, or use the '-LLIBDIR'
flag during linking and do at least one of the following:- add LIBDIR to the 'LD_LIBRARY_PATH' environment variableduring execution- add LIBDIR to the 'LD_RUN_PATH' environment variableduring linking- use the '-Wl,-rpath -Wl,LIBDIR' linker flag- have your system administrator add LIBDIR to '/etc/ld.so.conf'See any operating system documentation about shared libraries for
more information, such as the ld(1) and ld.so(8) manual pages.

安装 NTL

安装好 GMP 之后再编译 NTL，计算效率快得多，

For this to work, GMP must already be installed (most Unix distributions already come with GMP installed, but see this page for more details). If you really do not want to use GMP, you can pass the option NTL_GMP_LIP=off to configure; however, NTL will run significantly faster with GMP, so this is strongly discouraged.

安装好 gf2x 之后再编译 NTL，使得 GF(2) 的效率快得多，

If you want very high-performance for polynomial arithmetic over GF(2), you may want to consider using the gf2x library. To do this, gf2x must already be installed. In addition, you should invoke configure with the option NTL_GF2X_LIB=on.

1. 下载最新版本的 NTL，我们下载 ntl-11.5.1.tar.gz 压缩文件，在 Linux 下解压

   gunzip ntl-11.5.1.tar.gztar xf ntl-11.5.1.tarcd ntl-11.5.1/src/
   

2. 默认配置了 GMP，我们额外配置 gf2x，

   ./configure PREFIX=/usr/local NTL_GF2X_LIB=on GF2X_PREFIX=/usr/local
   

3. 编译

   makemake checksudo make install
   

4. 如果执行 make check 时找不到 .so 的软连接，删除后使用绝对路径重新配置下，

   sudo rm libgf2x.so.4sudo rm libgf2x.sosudo ln -s /usr/local/lib/libgf2x.so.4.0.0 /usr/local/lib/libgf2x.so.4sudo ln -s /usr/local/lib/libgf2x.so.4.0.0 /usr/local/lib/libgf2x.sosudo ldconfig
   

安装结果：

mkdir -p -m 755 /usr/local/include
rm -rf /usr/local/include/NTL
mkdir -m 755 /usr/local/include/NTL
cp -p ../include/NTL/*.h /usr/local/include/NTL
chmod -R a+r /usr/local/include/NTL
mkdir -p -m 755 /usr/local/share/doc
rm -rf /usr/local/share/doc/NTL
mkdir -m 755 /usr/local/share/doc/NTL
cp -p ../doc/*.txt /usr/local/share/doc/NTL
cp -p ../doc/*.html /usr/local/share/doc/NTL
cp -p ../doc/*.gif /usr/local/share/doc/NTL
chmod -R a+r /usr/local/share/doc/NTL
mkdir -p -m 755 /usr/local/lib
cp -p ntl.a /usr/local/lib/libntl.a #LSTAT
chmod a+r /usr/local/lib/libntl.a #LSTAT

安装 Bazel

Bazel 是 Google 开源的编译构建工具，以 Monolithic Repository 为理念。与 makefile & CMake 不同，Bazel 另起炉灶，采用 client/server 运行模式，为云编译而生。Bazel 工具将编译过程分三个阶段：Load Phase/Analysis Phase/Execution phase。研发人员实现 workspace/build/.bzl 三种文件，Bazel 执行这些文件生成 action graph，执行 action 来构建项目。

下载 bazel，我们下载 installer-linux-x86_64.sh 二进制安装程序，

chmod +x bazel-6.4.0-installer-linux-x86_64.shsudo cp ./bazel-6.4.0-installer-linux-x86_64.sh /usr/local/bin/cd /usr/local/bin/./bazel-6.4.0-installer-linux-x86_64.sh

安装结果：

Bazel is now installed!Make sure you have "/usr/local/bin" in your path.For bash completion, add the following line to your ~/.bashrc:source /usr/local/lib/bazel/bin/bazel-complete.bashFor fish shell completion, link this file into your
/root/.config/fish/completions/ directory:ln -s /usr/local/lib/bazel/bin/bazel.fish /root/.config/fish/completions/bazel.fishSee http://bazel.build/docs/getting-started.html to start a new project!

使用 Bazel 编译 ctmalloc 源码时，它总是去链接 https://github.com/protocolbuffers/protobuf/archive/13d559beb6967033a467a7517c35d8ad970f8afb.zip 下载 com_google_protobuf，但是报错 Connection refused。明明用浏览器可以打开这个网址啊！无语。。。

安装 ctmalloc

ctmalloc 是一个高效管理内存的工具包，需要使用 bazel 来编译源码，但它连不上 github，编译不了！！！我们通过安装 gperftools 来实现 ctmalloc 的安装。

TCMalloc (Thread-Caching Malloc) 与标准 glibc 库的 malloc 实现一样的功能，但是 TCMalloc 在效率和速度效率都比标准 malloc 高很多。TCMalloc 是 google-perftools 工具中的一个（四个工具分别是：TCMalloc、heap-checker、heap-profiler 和 cpu-profiler）。

1. 下载 libunwind（追踪函数调用栈），源码安装

   autoreconf --force -v --install./configuremakesudo make install
   

2. 下载 gperftools（CPU 性能分析器），源码安装

   autoreconf --force -v --install./configuremakesudo make install
   

3. 最后把 ctmalloc 加载到 Linux 系统中，

   suecho '/usr/local/lib' > /etc/ld.so.conf.d/local.conf/sbin/ldconfigexit
   

编译 OpenFHE

1. 在 https://github.com/openfheorg/openfhe-development 下载 OpenFHE 的源代码，解压得到 openfhe-development-main

2. 递归下载依赖的第三方代码（本来是空文件夹），

   cd ./third-partygit initgit submodule update --init --recursive
   

3. 我们配置 ./CMakeLists 文件，打开 WITH_NTL, WITH_TCM 等优化选项（如果你没有安装它们，就不要打开），构造出 Makefile 文件，

   mkdir buildcd buildcmake .. BUILD_EXTRAS=ON WITH_NTL=ON WITH_TCM=ON
   

4. OpenFHE 的源码文件很大，我们启用多线程 ，

   make -j 16
   

5. 根据需求可以安装到系统中（在 ./build 下执行 sudo make uninstall 即可卸载），

   make install
   

现在我们根据 ./unitest 中的三个测试代码，做正确性测试，

make testall

运行了好长时间后（主要是 pke 的 1489 cases 很慢），得到的测试结果，
