Обсуждение: compile error of 7.4 beta1 on AIX 4.3.3

I'm using xlc v 5.0 on AIX 4.3.3 to compile 7.4 beta1and got the error
below:
--------------------------------------------8<-------------------------------------------------------------------
xlc -O2 -qmaxmem=16384 -qsrcmsg -qlonglong -I../../../src/include
-I/usr/local/include/  -c -o hba.o hba.c
      651 |                 hints.ai_flags = AI_NUMERICHOST;
            .................................a..............
a - 1506-045 (S) Undeclared identifier AI_NUMERICHOST.
     1237 |         hints.ai_flags = AI_NUMERICHOST;
            .........................a..............
a - 1506-045 (S) Undeclared identifier AI_NUMERICHOST.
-----------------------------------------8<-----------------------------------------------------------------------

it seems we should use NI_NUMERICHOST in AIX, for I check the
/usr/include/netdb.h
there can't find AI_NUMERICHOST, just NI_NUMERICHOST. change AI_NUMERICHOST
to NI_NUMERICHOST fixed the problem. But I don't konw the best way to
fix it.

the other problem is that I'll have to comment out the
#include "ldfcn.h"
in src/backend/port/dynloader.c to get compile continue.

and another platform problem:

---------------------------------------8<-------------------------------------------------------------------------
make[4]: Entering directory
`/home/postgres/pgsql-7.4/postgresql-7.4beta1/src/backend/utils/error'
xlc -O2 -qmaxmem=16384 -qsrcmsg -qlonglong -I../../../../src/include
-I/usr/local/include/  -c -o elog.o elog.c
      546 |                 case 17: /* Directory not empty */
            .....................a............................
a - 1506-052 (S) Duplicate case label for value 17. Labels must be unique.
-------------------------------------8<---------------------------------------------------------------------------

in /usr/include/errno.h:

-------------------------------------8<---------------------------------------------------------------------------
/*
 * AIX returns EEXIST where 4.3BSD used ENOTEMPTY;
 * but, the standards insist on unique errno values for each errno.
 * A unique value is reserved for users that want to code case
 * statements for systems that return either EEXIST or ENOTEMPTY.
 */
#ifdef _ALL_SOURCE
#define ENOTEMPTY       EEXIST  /* Directory not empty */
#else   /* not _ALL_SOURCE */
#define ENOTEMPTY       87
#endif  /* _ALL_SOURCE */
-------------------------------------8<---------------------------------------------------------------------------

the default ENOTEMPTY is equal to EEXIST, so the error above.
don't know how to make _ALL_SOURCE macro effect, so I can't send a patch
now.

and  src/interfaces/libpq/fe-connect.c, still AI_NUMERICHOST problem.

and finally, the ecpg package:

-------------------------------------8<---------------------------------------------------------------------------
make[4]: Entering directory
`/home/postgres/pgsql-7.4/postgresql-7.4beta1/src/interfaces/ecpg/pgtypeslib'

try to fix that later, report here first.

I don't think that's a good fix --- those are different symbols with
different purposes (and even different values, on other platforms).

Looking at src/include/getaddrinfo.h, it seems we assume we need to
supply definitions of AI_NUMERICHOST and NI_NUMERICHOST if and only
if not HAVE_STRUCT_ADDRINFO.  That's probably a bogus assumption.
Can you tell us what configure found for HAVE_STRUCT_ADDRINFO and
HAVE_GETADDRINFO?  Also, which of the macros defined in that file
exist in your system headers?

I think this is fixed as of CVS tip --- please try it on AIX.

BTW, problems with beta releases are better reported in -hackers or
-bugs than in -general.

OK, the AI_NUMERICHOST problem removed with current cvs tip.
Still we got the duplicated value of ENOTEMPTY   and    EEXIST error.
would try to solve it and report back later.

Thanks and regards
