环境准备
pip 安装 docutils 时报错
(.venv) 🍺 /root/downloads/openssl ☞ git:(master) pip install docutils
WARNING: pip is configured with locations that require TLS/SSL, however the ssl module in Python is not available.
WARNING: Retrying (Retry(total=4, connect=None, read=None, redirect=None, status=None)) after connection broken by 'SSLError("Can't connect to HTTPS URL because the SSL module is not available.")': /simple/docutils/
需要安装 OpenSSL 之后重新编译 Python, 以安装 Python 3.10 为例，它对 OpenSSL 版本有要求，默认版本太低, 需要重新编译 OpenSSL。其编译时依赖 perl modules。
Could not build the ssl module!
Python requires a OpenSSL 1.1.1 or newer
(.venv) ➜ /root/downloads/openssl ☞ git:(master) yum install perl-core
(.venv) ➜ /root/downloads/openssl ☞ git:(master) ./Configure
(.venv) ➜ /root/downloads/openssl ☞ git:(master) make -j 8
(.venv) ➜ /root/downloads/openssl ☞ git:(master) make install
OpenSSL 相关的文件和动态链接库默认存放在 /usr/local/bin /usr/local/lib64/ /usr/local/share/doc/openssl /usr/local/ssl /usr/local/include/openssl等目录。
(.venv) 🍺 /root/downloads/openssl ☞ git:(master)ln -s /usr/local/lib64/libssl.so.3 /usr/lib64/libssl.so.3
(.venv) 🍺 /root/downloads/openssl ☞ git:(master)ln -s /usr/local/lib64/libcrypto.so.3 /usr/lib64/libcrypto.so.3
重新编译安装 Python 3.10
./configure --with-openssl=/usr/local --with-openssl-rpath=auto --enable-optimizations
make
make install
如果出现如下编译错误：
/root/downloads/Python-3.10.0/Modules/_ctypes/_ctypes.c:107:10: fatal error: ffi.h: No such file or directory
#include <ffi.h>
^~~~~~~
compilation terminated.
安装 libffi libffi-devel
(.venv) 🍺 /root/downloads/Python-3.10.0 ☞ sudo yum -y install libffi libffi-devel
在 Python 安装包下执行 make 时还是会报 Could not build the ssl module!，查看 configure 文件和 setup.py 发现端倪，原来 configure 文件里在设置 OPENSSL_LDFLAGS 参数时默认是在你指定的目录下的 lib 文件中 查找，即 OPENSSL_LDFLAGS="-L$ssldir/lib"，而手动编译的 OpenSSL 动态链接库安装在 /usr/local/lib64 下面，因此需要修改 configure 文件。然后重新编译即可。
OPENSSL_LDFLAGS="-L$ssldir/lib64"
编译 rdma-core
上面的环境准备就是为了修复如下错误

如果 make install 报错

发现 make install 还是报错。换成 ninja 编译后成功。
export EXTRA_CMAKE_FLAGS="-DCMAKE_BUILD_TYPE=Debug -DENABLE_WERROR=1"
mkdir -p build && cd build
cmake -G Ninja CFLAGS="-O0 -g" -DCMAKE_INSTALL_PREFIX=/usr ..
ninja
ninja install
Ninja 延伸
Ninja 相对于 Makefile 这套工具更注重于编译速度。
- 可以生成编译依赖关系图，可以使用
dot来生成图片。
🍺 /root/go/src/github.com/linux-rdma/rdma-core/build ☞ git:(master) ninja -t graph all
-
ninja依赖于build.ninja文件，根据CmakeLists.txt运行cmake -G Ninja来生成这个配置文件。 -
通过执行
ninja -t list可以查看ninja中集成了哪些工具。
