python - 从源代码构建 Python 和 OpenSSL，但 ssl 模块失败

Question

我正在尝试从容器中的源代码构建 Python 和 OpenSSL。两者似乎都正确构建，但 Python 没有成功创建 _ssl模块。

我找到了 few guides在线说取消注释和来自 Python 的行 - 3.X.X/Modules/Setup并添加 --openssldir=/usr/local/ssl标记到 ./configure OpenSSL 的步骤。我在我的 dockerfile 中执行这些操作。这导致在 ./configure 期间Python 的输出，我看到以下行。

checking for X509_VERIFY_PARAM_set1_host in libssl... yes

但是我收到以下错误:

[91m*** WARNING: renaming "_ssl" since importing it failed: /usr/lib/x86_64-linux-gnu/libssl.so.1.1: version `OPENSSL_1_1_1' not found (required by build/lib.linux-x86_64-3.8/_ssl.cpython-38-x86_64-linux-gnu.so)
[0m[91m*** WARNING: renaming "_hashlib" since importing it failed: /usr/lib/x86_64-linux-gnu/libcrypto.so.1.1: version `OPENSSL_1_1_1' not found (required by build/lib.linux-x86_64-3.8/_hashlib.cpython-38-x86_64-linux-gnu.so)
[0m
Python build finished successfully!

...

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


Could not build the ssl module!
Python requires an OpenSSL 1.0.2 or 1.1 compatible libssl with X509_VERIFY_PARAM_set1_host().
LibreSSL 2.6.4 and earlier do not provide the necessary APIs, https://github.com/libressl-portable/portable/issues/381

如果 ./configure找到 X509... ，为什么我仍然收到 hashlib 和 ssl 错误？

完整的 Dockerfile，FWIW:

FROM jenkins/jenkins:lts
USER root
RUN apt-get update && apt-get install -y apt-utils gcc make zlib1g-dev \
    build-essential libffi-dev checkinstall libsqlite3-dev 
RUN wget https://www.openssl.org/source/openssl-1.1.1d.tar.gz && \
    tar xzf openssl-1.1.1d.tar.gz && \
    cd openssl-1.1.1d && \
    ./config -Wl,--enable-new-dtags,-rpath,'$(LIBRPATH)' --prefix=/usr/local/ssl --openssldir=/usr/local/ssl && \
    make && \
    make test && \
    make install
RUN wget -q https://www.python.org/ftp/python/3.8.2/Python-3.8.2.tgz && \
    tar -xzf Python-3.8.2.tgz && \
    cd Python-3.8.2 && \
    ./configure && \
    make && \
    make install

从源代码构建 openssl 时似乎出现安装问题。对于 _ssl 上的构建失败模块，尝试额外的选项，如 --with-openssl , CFLAGS和 LDFLAGS使用脚本 ./configure 配置 Python 时，例如

./configure  --with-openssl=/PATH/TO/YOUR/OPENSSL_INSTALL_FOLDER/ \
    --enable-optimizations \
    --with-ssl-default-suites=openssl \
    CFLAGS="-I/PATH/TO/YOUR/OPENSSL_INSTALL_FODLER/include" \
    LDFLAGS="-L/PATH/TO/YOUR/OPENSSL_INSTALL_FODLER/"

也试试这个命令openssl version ，如果它报告这样的错误:

/usr/lib/x86_64-linux-gnu/libssl.so.1.1: version `OPENSSL_1_1_1' not found

这意味着您的 openssl 库存在链接问题，我不确定您使用的是 Linux 还是其他系统，但对于 Linux 系统，您可以手动修改 openssl 库的链接来解决问题，如 in my answer at here 所述.
