【问题描述】：

我想将默认的python2.6.6从源代码升级到python2.7，我安装了：

yum groupinstall "Development tools"
yum install zlib-devel bzip2-devel openssl-devel ncurses-devel sqlite-devel readline-devel tk-devel

但是 _hashlib 和 _ssl 构建失败。

我的 openssl 已安装：

whereis openssl
openssl: /usr/bin/openssl /usr/lib/openssl /usr/lib64/openssl /usr/local/bin/openssl /usr/include/openssl /usr/share/man/man1/openssl.1ssl.gz

我取消注释关于 ssl 配置的模块/设置，如下所示：

# Socket module helper for socket(2)
_socket socketmodule.c timemodule.c

# Socket module helper for SSL support; you must comment out the other
# socket line above, and possibly edit the SSL variable:
SSL=/usr/local/ssl
_ssl _ssl.c \
        -DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl \
        -L$(SSL)/lib -lssl -lcrypto

然后

./configure --prefix=/usr/local/python27/ --enable-shared
make

它有错误：

make: *** [Modules/_ssl.o] Error 1

如果不使用ssl，make不是这个错误，它显示：

Python build finished, but the necessary bits to build these modules were not found:
bsddb185           dl                 imageop         
sunaudiodev                                           
To find the necessary bits, look in setup.py in detect_modules() for the module's name.


Failed to build these modules:
_hashlib           _ssl

我想知道如何解决这个问题，谢谢。

【问题讨论】：

我通过从另一台可以编译成功的机器上复制失败的模块来解决这个问题。

【解决方案1】：

尝试将包括 stderr 和 stdout 在内的 make 命令的输出重定向到一个文件，然后查看该日志。就我而言，我使用的是系统中安装的不同的openssl 库。删除该库文件夹后，make 采用了正确的 openssl 库。
