ImportError: No module named _struct
make: *** [libinstall] 错误 1

In directory /WORK/suzc/software/Python-2.7.3, I do this:
suzc@linux-opensuse:22:33:28:Python-2.7.3$ ./configure --prefix=/WORK/suzc/installed/python --exec-prefix=/WORK/suzc/installed/python --mandir=/WORK/suzc/installed/man | tee -a config_make.20120614.log
make install

and then meets the install error!!

python's version is 2.7.3, i download the .tgz & .bz2, both the some problem.

My system is:
suzc@linux-opensuse:22:33:28:Python-2.7.3$ uname -a

Ned Deily <> added the comment:

I have no experience with opensuse but, from a general unix install install view, the most obvious cause of that message would be a build failure of the _struct extension. Check the log file for messages with _struct in it. You could also try to check the paths and to import it in the build directory:

PYTHONPATH=/WORK/suzc/installed/python/lib/python2.7 \
./python -c 'import sys; print(sys.paths)'
PYTHONPATH=/WORK/suzc/installed/python/lib/python2.7 \
./python -c 'import _struct; print(_struct.__file__)'

Thank for your attention.

I try it:

And I read the log of make, it seems to be compiled OK:

_struct.o and are just there, I truely don't know what's wrong.
Newly to Python, I think python should not have such an installation problem.

I installed it(2.7.3) on RHEL5, works OK, but I want to install OpenSSL to it, don't know how to do it, so I learn to install it on SUSE in my workplace while RHEL5 is in another place.

RHEL5 has python 2.4.2, in my memory. SUSE12 has python 2.7.2.

Does system's python affect my installtion? But I think it shouldn't.

In fact, long before I downloaded a compressed package named Python-2.7.3.tar.bz2, with this one, I can make && make install, but I can't run it, error is:

suzc@linux-opensuse:22:12:31:bin$ ./python2.7

raise IOError(msg)
IOError: invalid Python installation: unable to open /WORK/suzc/installed/python /lib/python2.7/config/Makefile (No such file or directory)

I'm crazy about this, I search it in google, no satisfatory answers. So I want to download a new one 2.7.3, and install, but i just can not install it.

Thanks again.
