如何编译Python 3.4与自定义OpenSSL？
我在非标准位置安装了自己的OpenSSL安装（本例为/my/path ），我希望Python 3.4能够针对源代码进行编译。 我试过的是这个（目录缩写）
CPPFLAGS="-I/my/path/include -I/my/path/include/openssl" ./configure --prefix=/my/path/
我也试着用C_INCLUDE_PATH和冒号分隔的path。
然后，我运行make并得到这个：
building '_ssl' extension gcc -pthread -fPIC -fno-strict-aliasing -DNDEBUG -g -fwrapv -O3 -Wall -Wstrict-prototypes -I./Include -I. -IInclude -I/my/path/include -I/my/path/include/openssl -I/usr/local/include -I/my/path/Python-3.4.0/Include -I/my/path/Python-3.4.0 -c /my/path/Python-3.4.0/Modules/_ssl.c -o build/temp.linux-x86_64-3.4/my/path/Python-3.4.0/Modules/_ssl.o gcc -pthread -shared build/temp.linux-x86_64-3.4/my/path/Python-3.4.0/Modules/_ssl.o -L/my/path/lib -L/usr/local/lib -lssl -lcrypto -o build/lib.linux-x86_64-3.4/_ssl.cpython-34m.so *** WARNING: renaming "_ssl" since importing it failed: build/lib.linux-x86_64-3.4/_ssl.cpython-34m.so: undefined symbol: SSL_get0_next_proto_negotiated
它正在寻找SSL_get0_next_proto_negotiated ，但这是最确定的：
$ grep SSL_get0_next_proto_negotiated /my/path/include/openssl/* /my/path/include/openssl/ssl.h:void SSL_get0_next_proto_negotiated(const SSL *s,
我不确定我做错了什么，有什么想法？
经过大量的拉毛，我设法解决了这个问题。 这是一堆环境variables…我想我可能做了一点矫枉过正，但这基本上工作：
# OpenSSL 1.0.1g ./config shared --prefix=/my/path --openssldir=/my/path/openssl make make install # Python 3.4 export LDFLAGS="-L/my/path/lib/ -L/my/path/lib64/" export LD_LIBRARY_PATH="/my/path/lib/:/my/path/lib64/" export CPPFLAGS="-I/my/path/include -I/my/path/include/openssl" ./configure --prefix=/my/path/ make make install
感谢@ScottFrazer的回答。 为我节省了很多麻烦。
这里是我在ubuntu中用最新的openssl 1.0.2g编译python的openssl 1.0.2g 。
# new openssl install curl https://www.openssl.org/source/openssl-1.0.2g.tar.gz | tar xz && cd openssl-1.0.2g && ./config shared --prefix=/usr/local/ && make && make install # Python install script export LDFLAGS="-L/usr/local/lib/" export LD_LIBRARY_PATH="/usr/local/lib/" export CPPFLAGS="-I/usr/local/include -I/usr/local/include/openssl" apt-get update apt-get install build-essential checkinstall -y apt-get install libreadline-gplv2-dev libncursesw5-dev libssl-dev libsqlite3-dev tk-dev libgdbm-dev libc6-dev libbz2-dev -y cd /home/web/ wget https://www.python.org/ftp/python/2.7.11/Python-2.7.11.tgz | tar xzf Python-2.7.11.tgz && cd Python-2.7.11 ./configure --prefix=/usr/local/ make altinstall
注意，安装是一个altinstall ，这意味着它不会覆盖Ubuntu的默认Python。 validation安装是否成功：
/usr/local/bin/python2.7 >>> import ssl >>> ssl.OPENSSL_VERSION 'OpenSSL 1.0.2g 1 Mar 2016'
这是我在3.4中解决的。 适用于2.7和3.4。 ./configure中的重要的是–with-ssl config参数：
wget https://www.python.org/ftp/python/3.4.3/Python-3.4.3.tgz tar -xf Python-3.4.3.tgz cd Python-3.4.3/ sudo yum install gcc ./configure --with-ssl make && make install # If you like to live dangerously since this will overwrite default python executable make && make altinstall # Safer because you access your new Python using python3.4
