centos6.2升级python2.7 _hashlib和_ssl构建失败，并生成[模块/_ssl.o]错误1

Question

我想把默认的python2.6.6从源码升级到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

我取消了关于ssl配置的Module/Setup注释，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，则make不是此错误，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         

我想知道怎么解决这个问题，谢谢。

尝试将make命令的输出(包括stderr和stdout )重定向到一个文件，然后遍历该日志。在我的例子中，我使用的是安装在我的系统中的另一个openssl库。在删除该库文件夹之后，make采用了正确的openssl库。
