Description Torsten Werner 2005-03-02 02:16:04 UTC
Symptom: A error message appears, that the option TCP_NODELAY is unknown

Problem: in include.h is a special handling for HP-UX 11 defined. TCP_NODELAY
and TCP_MAXSEG will be undefined before shadow.h, rpc/rpc.h and rpcsvc/yp_prot.h
will be included. This is done to suppress compiler warnings about redefined

But shadow.h is the only one file which redefines TCP_MAXSEG and TCP_NODELAY.

The other undef statements are "finally" samba is compiled without this socket

A patch is attached. But unfortunately I can test it at HPUX 11i only. In any
case it would be better to have a compiler warning then to undef the option.

Fix for TCP_NODELAY at HPUX 11i

Apply the patch to include/includes.h
It will do the following:
- remove the undef statements for HPUX at wrong places
- create a compiler warning if TCP_NODELAY and TCP_MAXSEG is not redefined by

It is tested at HP-UX 11i with gcc 3.3.1
