Thread: BUG #6758: ./configure script sets HAVE_WCSTOMBS_L 1
The following bug has been logged on the website: Bug reference: 6758 Logged by: jez wain Email address: jez.wain@bull.net PostgreSQL version: 9.1.4 Operating system: AIX 7.1 Description:=20=20=20=20=20=20=20=20 Building Postgresql on AIX7.1 with IBM's xlc compiler I got an undefined symbol error on the link phase for the 'postgres' binary: ld: 0711-317 ERROR: Undefined symbol: .mbstowcs_l ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information. AIX7 supports the mbstowcs API but not mbstowcs_l. In src/include/pg_config.h I commented out the define for HAVE_WCSTOMBS_L 1, recompiled src/backend/utils/adt/pg_locale.c and the build completed successfully. This indicates that the ./configure script does not correctly detect the absence of the locale specific wide-character/multi-byte API's (xxxx_l), on AIX (near line 18945)

Alvaro,=20 This is indeed the same problem; my apologies for posting a duplicate. I've checked on two AIXv7.1 servers, one using an xlCv11 runtime, the other= using an xlCv12 runtime.=20 On the v11 neither mbstowcs_l nor wcstombs_l are defined. On the v12, both= are. So to answer the question posed on the archive link you provided, the= assumption made by your configure script appears to be valid. This points= to there being a problem in the way the presence of these APIs is detected= in the configure script. I built postgres on the V11 platform when I posted my bug report. I'll hav= e a go on the V12 to ensure that this error goes away.

OK, now we understand what we're dealing with at least. Can you look
into why mbstowcs_l is misdetected on v11? The portion of config.log
where configure is probing for that function might be illuminating.

Following up on getting PG built on AIXv7.1, I too have hit the same issue reported in BUG #6758. The posting of Thu, 26 Jul 2012 11:13:03 states that the problem does *not* occur using the IBM xlc v12 compiler but *does* occur using the v11 compiler. From what I have seen, the same issue still exists with the v12 compiler. Here's the version info I see from xlc:- $ xlc -qversion IBM XL C/C++ for AIX, V12.1 (5765-J02, 5725-C72) Version: 12.01.0000.0000 AIX is at version 7.1.0.0 I've applied the same "workaround" documented in this bug, and then the build succeeds OK. I'm currently working on a project where I need to get PGv9.1 up and running on an IBM AIXv7.1 server, so I do have access to a suitable machine for a period of time if I can provide any further diags to help resolve the issue. I'll try and see if I can get longer term access to this in order to participate in the build farm, but it may not be possible "politically" where I work. I'm more a Java/JDBC type person and can't confess to being a C guru, so please make any follow-up requests for extra diags as simple as possible please ;-) Andrew

That would be helpful, because both of the previous complainants seem
to have wandered off without helping us get to the bottom of it :-(.
What I'd like to see at this point is the portion of config.log where
the configure script is trying to probe for wcstombs_l. For example,
on a machine that has wcstombs and not wcstombs_l, I see:
...

It would also be interesting to check what would happen if configure
actually tried to probe for mbstowcs_l, instead of making assumptions.
To do that, copy the test program above (removing the "| " indentation),
replace "wcstombs_l" by "mbstowcs_l", and then try to compile it ---
but be sure to use the compile command shown in your config.log, not
mine.

Hi Tom,
Thanks for the pointers. Hopefully some of the following may shed some
light on the issue.

"wctsombs_l" :-

Thanks for the results. It seems difficult to come to any conclusion
other than that AIX has got wcstombs_l but not mbstowcs_l ... which is
darn bizarre; I'd suggest reporting it as a bug to IBM.
In the meantime, it seems like what we had better do is explicitly
test for both functions, rather than making the assumption that they
would both or neither be present. I'm not sure if we can provide any
extra functionality if only wcstombs_l is available --- that will
have to emerge in making the patch. We can certainly build without
it though.
As a temporary workaround, you should probably just modify pg_config.h
after configure runs, to remove the HAVE_WCSTOMBS_L symbol.

Confirm that the workaround works just fine. Now have PG 9.1.5 up and running on AIX just fine. Thanks. Andrew > > regards, tom lane > >

If you have time, perhaps you'd like to apply the committed patch: http://git.postgresql.org/gitweb/?p=postgresql.git;a=commitdiff;h=97395185b85b786523ee41225b53bd84c98d34f4 and confirm that all is well when using that. regards, tom lane
Apologies for delay in progressing this, but I only have access to an AIX7.1 system periodically. Just to confirm that source build of 9.2.1 release now builds clean against AIXv7.1 with xlc v12.1 compiler.
