Summary: HP-UX: Problem building socket
Initial Comment:
On HP-UX 11, I get errors compiling Python 2.1.1 from
source.
It crashes when parsing sys/socket.h
Here's the offending code:
extern sbsize_t sendfile __((int, int, off_t,
bsize_t,
const struct iovec *,
int));
extern sbsize_t sendpath __((int, char *, off_t,
bsize_t,
const struct iovec *,
int));
When I switch from gcc to cc (native c compiler) the
socket
library compiles, but many other libs don't.
(sidenote: when using cc, cc is noteably faster than
gcc)

The likely cause is that sbsize_t is not defined. Please try
to find out what header file of HP-UX defines sbsize_t, and
under what conditions?
Outright including that header file probably is the wrong
solution, so please also find out where it is included from,
tracking it eventually back to socket.h. It appears that a
certain #define is missing to cause a proper definition of
sbsize_t. We must find out what that define is, and why it
is not set when compiling with gcc.
Also, could you please identify yourself?

Here are the offending lines from socket.h

extern sbsize_t sendpath __((int, char *, off_t, bsize_t,

However, my medium c skills tell me that the lines are ok.
I cannot offer an explanation why gcc fails here.

gcc 2.95 does not support HP-UX 11; this appears to be an
instance of that problem. The __va__list problem is not at
all Python-specific; it occurs in many packages (just search
Google for "HP-UX __va__list"). With such problems, there is
no point into looking further into the problem; just drop
the compiler. If you want to port Python to HP-UX and gcc
2.95, you are on your own.
Notice that gcc 3.0.1 *does* support HP-UX 11; I recommend
to upgrade.

I now thought that since the errors happen in a system
header that compiles with
cc and not gcc, why not copy <sys/socket.h> to "socket.h"
and delete the two offending lines.
However, as you see, <sys/socket.h> is still included (why
?).
Another option is using cc just for this library, but I'm
not sure, that the object files are compatible. Using cc
alone creates a lot of non-working modules, although it is
in (extended) ANSI mode.
I also tried the HP Porting centre (http://hpux.asknet.de)
but the Python 2.1 package there -just like mine- does crash
on importing socket (too with 2.2b1)
hp18: Python-2.2b1 % ./python

It would be helpful if you would provide all details in a
report also. When you say "it crashes", did you really
mean "it crashes" (i.e. with a core dump, machine reboot,
or the like)?
If the compiler merely rejected the code, it would be good
to see what the error message was.
Please also report version numbers: HP-UX version, gcc
version, etc. Are you sure you are using a gcc built for
your OS version? If the gcc doesn't get prototypes right,
this often comes from having fixincluded header files of a
different OS version.

Please try again with Python 2.2b1 (http://python.org/2.2/).
We've done a lot of work and we've got at least one report
that it now works out of the box on HP-UX 11. I'd like to
hear if that solves your problems (and if 2.2b1 builds with
either compiler).
