HI!

I'm trying to build Python2.4 on a rather old Debian
machine. 
Building _socket fails (see below) although I tried to use

configure --disable-ipv6

I've added

#define INET_ADDRSTRLEN 16

to Modules/socketmodule.h which made it work. There
were no problems compiling Python2.2 on the very same
machine.

Ciao, Michael.

How old a debian release is this? It sounds like it's a just
a broken system header, and I'm not entirely convinced that
adding this to the already-large collection of #ifdefs in
socketmodule is a path to happiness.

There are already a few attempts to define ADDRSTRLEN if it
is missing. Maybe we should just merge them into one, and
define it if it is not defined, independent of the system.

I have the same problem on Solaris 7.

I got:

My users then see...

I try your work-around.  Doesn't help.

Unfortunately, non of us has Solaris 7, so there is little
chance that we are able to develop a patch. Can you provide one?

I'm a SysAdmin.  My users (programmers) who want this 
version of Python claim to have put this fix in place and it 
works (on a copy I'm sure is squirreled away in someone's 
home directory).  Perhaps the account I'm using doesn't have 
something it needs in LD_LIBRARY_PATH, etc.?

I don't believe that this can still be a problem.
