Subject: 8.4 "kill" program fails to link on AIX 5.3
Date: Tue, 13 Apr 2010 17:36:56 -0400

Building coreutils-8.4 on a 64-bit AIX 5.3 system using GCC, I get this:

gmake[1]: Entering directory `/tmp/coreutils-build/src'
  CCLD     kill
ld: 0711-317 ERROR: Undefined symbol: .pthread_once
ld: 0711-317 ERROR: Undefined symbol: .pthread_getspecific
ld: 0711-317 ERROR: Undefined symbol: .pthread_setspecific
ld: 0711-317 ERROR: Undefined symbol: .pthread_key_create
ld: 0711-345 Use the -bloadmap or -bnoquiet option to obtain more information.
collect2: ld returned 8 exit status
gmake[1]: *** [kill] Error 1
gmake[1]: Leaving directory `/tmp/coreutils-build/src'
gmake: *** [all] Error 2

Everything else builds and links fine. Does the "kill" program need some 
special handling to make use of pthreads?

That's very strange.
Is the `timeout` util built for example as that uses
much the samem functions as `kill`.
It's like kill was being built with a different
toolchain (like xlc_r or something).

Could you provide the build output from `make V=1`.

cheers,
Pádraig.

The vendor compiler isn't even installed on this system; only GCC.

Of course. Here is the output from compiling and linking the "timeout" and 
"kill" programs:

So the above confirms that timeout and kill are being compiled and linked
with the same options. Therefore it must be something particular to kill.c
that's causing this.  A quick look shows that kill.c uses strsignal()
while timeout doesn't and I can now see that the gnulib replacement for
this function is implemented using thread local storage.

gnulib/modules/tls says to link $(LIBTHREAD), so could you try the following.
It that doesn't work, could you change $(LIBTHREAD) to $(LIBMULTITHREAD).

cheers,
Pádraig.

Indeed, that does the trick! Adding either of $(LIBTHREAD) or 
$(LIBMULTITHREAD) to kill_LDADD allows the program to link successfully.

Thanks for testing.
I've just pushed that fix.
