Hi guys,
  I was knocked down by a error related to a socket library _socket.so when I was trying to compile distribute-0.6.14:

# python3 setup.py install
Before install bootstrap.

Could anyone advise what does this error message mean?

Thanks in advance,

Looks like a compilation problem.  Did you install that Python yourself?  Can you run the test suite to see if there are problems with the _socket module?

Hi Eric,
   Thank you for the reply. I installed Python 3.1.2 pre-compiled by sunfreeware.com on one of our sparc servers.
   Would you please let me know what command I should run to test the installation?

Regard,

Alex

$ python3.1 -m test.regrtest

If your distribution removes tests from the binary package, this won’t work.

The test fialed on my workstation while successul on another server. Both server has the same Pyton installation but different libc and libm version. I plan to reinstall the OS(solaris 10 pre-release) on my workstation next week and see how it goes.

Regards,

Alex

It would be helpful if you could attach the test log.  Alternatively, if the configure and build log for your Python package is available somewhere on the web, the link would be useful.

I've installed it successfully on another server. That is enough. I haven't got time to upgrade my workstation from s10 pre-release to latest s10 release yet.


Thanks for the information,

Alex

Is the original bug still present in your new install?

I haven't get time to upgarde my workstation yet. I don't know when I'm going to do it. I compile the software successfully on the other server. and that's enough for me.

Thanks,
Alex

> Is the original bug still present in your new install?
I meant your server.  I’d like to know whether this is a legit but or not.

No bugs.

All right.  Don’t hesitate to report any other bugs you find in the future.

I guys I have the same problem with solaris 10 and the pre-compiled package python-3.1.2 downloaded from sunfreeware.com

Can you download a Python 3.1.3 from python.org (or better, clone the 3.1 repository from hg.python.org), try to compile it and report errors?  We can’t do anything for files provided by sunfreeware, but we can fix platform-specific problems if they come from our code.

I have some problem to compile python source code to my server, I can't install make.
My problem is only when import the smtplib.

I install the Python package compiled by sunfreeware.

FWIW, this same problem exists with 2.7.1, compiled by myself, and only on some Solaris 10 boxes of ours that have not had a lot of recent patching.

==================================================================

On an old-ish Solaris 10 box:

On Linux:
>nm -C /lib/libc.so.6 |grep ' inet_aton'
00000000000cbce0 W inet_aton

This means that when Python is build with GCC (like on linux), inet_aton
is in system libc. 

If you build with GCC in solaris, inet_aton will be taken from the GCC lib dir. You need to put that GCC lib dir in your LD_LIBRARY_PATH when you run Python.
