pip 安裝 docutils 時報錯
(.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/
需要安裝 OpenSSL 之后重新編譯 Python, 以安裝 Python 3.10 為例杨帽，它對 OpenSSL 版本有要求鸿捧，默認版本太低, 需要重新編譯 OpenSSL铺然。其編譯時依賴 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 相關(guān)的文件和動態(tài)鏈接庫默認存放在 /usr/local/bin /usr/local/lib64/ /usr/local/share/doc/openssl /usr/local/ssl /usr/local/include/openssl等目錄且轨。
(.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
重新編譯安裝 Python 3.10
./configure --with-openssl=/usr/local --with-openssl-rpath=auto --enable-optimizations
make
make install
如果出現(xiàn)如下編譯錯誤：
/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.
安裝 libffi libffi-devel
(.venv) ?? /root/downloads/Python-3.10.0 ? sudo yum -y install libffi libffi-devel
在 Python 安裝包下執(zhí)行 make 時還是會報 Could not build the ssl module!浮声，查看 configure 文件和 setup.py 發(fā)現(xiàn)端倪，原來 configure 文件里在設(shè)置 OPENSSL_LDFLAGS 參數(shù)時默認是在你指定的目錄下的 lib 文件中 查找旋奢，即 OPENSSL_LDFLAGS="-L$ssldir/lib"泳挥，而手動編譯的 OpenSSL 動態(tài)鏈接庫安裝在 /usr/local/lib64 下面，因此需要修改 configure 文件至朗。然后重新編譯即可屉符。
OPENSSL_LDFLAGS="-L$ssldir/lib64"
編譯 rdma-core
上面的環(huán)境準備就是為了修復(fù)如下錯誤

如果 make install 報錯

發(fā)現(xiàn) make install 還是報錯。換成 ninja 編譯后成功。
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 延伸
Ninja 相對于 Makefile 這套工具更注重于編譯速度筑煮。
- 可以生成編譯依賴關(guān)系圖辛蚊，可以使用
dot來生成圖片粤蝎。
?? /root/go/src/github.com/linux-rdma/rdma-core/build ? git:(master) ninja -t graph all
ninja依賴于build.ninja文件真仲，根據(jù)CmakeLists.txt運行cmake -G Ninja來生成這個配置文件。通過執(zhí)行
ninja -t list可以查看ninja中集成了哪些工具初澎。
?? /root/go/src/github.com/linux-rdma/rdma-core/build ? git:(master) ninja -t list
