如何使用自制软件的openSSL在macOS上编译Python 3.6.2？

我之前发现的以前的答案都没有对我有用，但是我最终还是借助先前未提及的另一个答案来弄清楚了。这是实际的解决方法：https

基本上，CPPFLAGS和LDFLAGS不能在环境中设置。您需要在configure命令旁边进行设置，如下所示：

./configure CPPFLAGS="-I[openSSL install location]/include" LDFLAGS="-L[openSSL install location]/lib" [other flags here]

然后，在编译和安装后，它开始工作了！

$ python3 -c "import ssl; print(ssl.OPENSSL_VERSION)"OpenSSL 1.0.2l  25 May 2017

以下是无效的原因以及原因：

如何使用自定义OpenSSL编译Python
3.4？这无济于事，因为您无法在环境中设置LDFLAGS，CFLAGS或CPPFLAGS；setup.py不会将它们传递给实际的编译步骤。即使设置LD_LIBRARY_PATH可能起作用，您也不想这样做，因为这很危险（请参阅http://xahlee.info/UnixResource_dir/_/ldpath.html）。最后，–with-
ssl不是有效的configure参数，并且在那里列出的用于添加它的补丁程序并不适用。

当您尝试从源代码构建某些东西，而不是试图获取一个已经编译的dylib来查找重定位的库时，Homebrew拒绝链接OpenSSL并不适用。此外，在/ usr /
local中建立符号链接是很危险的，并且可能导致程序针对较新的标头进行编译，但使用较旧的系统二进制文件。

如何在MacOS上将ssl与python
build包括在一起无法正常工作。编辑setup.py以添加lib和include目录（用于安装OpenSSL的
部分位置） ，并且可以在SSL支持中进行编译。las，它们不可导入，因为旧版本仍在使用：

Following modules built successfully but were removed because they could not be imported:_hashlib   _ssl
