Python 2.7 ImportError：没有名为_ssl的模块

Question

I'm trying to build python 2.7 in Redhat with SSL. I've uncommented out the lines in Modules/Setup.dist:

SSL=/urs/local/ssl
_ssl _ssl.c
-DUSE_SSL -I$(SSL)/include -I$(SSL)/include/openssl
-L$(SSL)/lib -lssl -lcrypto

and I've ensured that OpenSSL is installed on the system, as well as openssl-devel.

Prior to installing openssl-devel after running make it would complain that it could not build the module _ssl . That error is now gone. Make successfully builds _ssl.o with no errors reported in the log, but does not build lib-dynload/_ssl.so - this is apparently the file that I need to get ssl to work. I'm running ./configure with the --enable-shared flag, but so far no matter how I alter the build environment, I can't get that library file to load.

I don't know about the details of building Python, but on Red Hat you might need to build OpenSSL with:

$ export CFLAGS="-fPIC"
$ ./config shared -no-ssl2 -no-ssl3 --openssldir=/usr/local/ssl ...
...
$ make depend
...
$ make all
...
$ sudo -E make install

After you make install, be sure sure the shared objects are in /usr/local/ssl/lib . I've encountered the "missing shared objects" on Fedora, and the above fixed the issue for me.
