[Problem here] Linux, 编译, Python, Hashlib, Openssl

linux_c_py_php

环境：Linux, 64bit, python2.7.3/python3.2.3, openssl1.0.1/openssl9.7.0
编译：
1, openssl :
   ./config --prefix=/home/liangdong/libs
   make -t
   make depend
2, python:
   ./configure --prefix=/home/liangdong/libs
    make & make install
分析:
从make打印的gcc command来看, 的确是指定了正确的Library路径, 可以找到libssl.so和libcrypto.so, 但我没看懂:

renaming "_hashlib" since importing it failed: libssl.so.1.0.0: cannot open shared object file: No such file or directory

这是想要表达什么意思, 无论如何, 我尝试了各种尝试, 谷歌了各种百度, 百度了各种谷歌, 最终未能resolve.

Python与openssl版本分别尝试过两个, 总共2 * 2 = 4种搭配方式, 未能成功, 错误相同, 希望找到遇过同样错误的有缘人.

编译时,
_posixsubprocess也报错, 我进去改了一下源码就好了, 但这个ssl找不到的问题我就很费解了, 应该是libssl.so 软链的 libssl.so.1.0.1 找不到, 这尼玛有找不到的理由吗? 不懂.

24小时围观此贴, 坐等好人.

自己解决:

          网上可以搜索到一个靠谱的答案, 虽然发生了一些变化, 但最终还是报错找不到libssl.so.1.0.1, 方法与编译结果如下:

1, 编辑Modules/Setup:

1. 209 # Socket module helper for socket(2)
   
2. 210 _socket socketmodule.c
   
3. 211
   
4. 212 # Socket module helper for SSL support; you must comment out the other
   
5. 213 # socket line above, and possibly edit the SSL variable:
   
6. 214 SSL=/home/liangdong/libs
   
7. 215 _ssl _ssl.c \
   
8. 216     -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
   
9. 217     -L$(SSL)/lib -lssl -lcrypto

复制代码

2, make, 报错:

1. gcc -pthread -L/home/liangdong/libs -Xlinker -export-dynamic -o python \
   
2.                 Modules/python.o \

发现是运行python加载动态库报错, 于是export LD_LILBRARY_PATH=/home/liangdong/libs/lib搞定.

是上天在磨砺我坚强的品质吗?...

linux_c_py_php

我只能说这个解决方案太烂了.... 我没权限改ld.so.conf, 只能加在自己的.bashrc里, 太不完美了.

有没有人遇见并修正过这个问题的.

cdtits

貌似主要问题还是 configure 时没有找到相关的库

linux_c_py_php

Python太没爱了, 这不是伤害我的心吗.

软连接 libssl.so.1.0.0存在吗？ln -s /home/liangdong/libs/libssl.so    /home/liangdong/libs/libssl.so.1.0.0行不行？

   

linux_c_py_php

存在的..

应该是python的脚本没处理好Modules, 安装在非标准路径下的有问题.

我直接依赖公司/usr/lib64下的ssl就可以了, 不考虑这个问题了.

编译Mod_python又是一堆错, 估计apache 2.4.2 版本太高了, 改够了.

你是怎么解决_posixsubprocess报错的？我在源代码文件里面找不到这个模块，就试着去找这个模块的补丁。没找着。就更别谈改代码了

    这个问题解决了，我找到模块文件了原来是c源文件我还以为是py文件找了半天没找着
