Sorry, I finally caught on, I build with xlc, not gcc on AIX. Which at
least explains why I've never hit this on AIX.
I do however build with gcc on PPC Linux on SLES-8 which uses gcc
3.(something). So yes, an "as" bug seems most likely since this doesn't
cause problems on Linux.
All I can suggest is that you get the sources for the as that came with
SLES-8 (www.suse.de will have those) and try to build it on AIX.

Subject: Re: Openssl AIX-64 bit build hangs
Here are the latest observations: (apologies in advance for the long mail).
Machine: AIX 5.1
gcc -v : 3.2 (I also have gcc 4.0 and observed the same behavior mentioned
below)
as -v: V5.1
$ ./Configure aix64-gcc
$ make
This hangs in the following command.
========
making all in crypto/bn...
make[3]: Entering directory
`/osd4/netezza/nz/urjit/openssl-0.9.8-stable-SNAP-20071004/crypto/bn'
gcc -I.. -I../.. -I../../include -DOPENSSL_THREADS -D_THREAD_SAFE
-DDSO_DLFC
N -DHAVE_DLFCN_H -maix64 -O -DB_ENDIAN -c -o aix_ppc64.o aix_ppc64.s
========
Then I ran the above command with -v, to check what gcc is actually doing:
========
$ cd crypto/bn
$
gcc -v -I.. -I../.. -I../../include -DOPENSSL_THREADS -D_THREAD_SAFE
-DDSO_D
LFCN -DHAVE_DLFCN_H -maix64 -O -DB_ENDIAN -c -o aix_ppc64.o aix_ppc64.s
Using built-in specs.
Target: powerpc-ibm-aix5.1.0.0
Configured with:
../configure --with-as=/usr/bin/as --with-ld=/usr/bin/ld --disable-nls
--ena
ble-languages=c,c++ --prefix=/opt/freeware --enable-threads
--enable-version
-specific-runtime-libs --host=powerpc-ibm-aix5.1.0.0
Thread model: aix
gcc version 4.0.0
/usr/bin/as -u -a64 -mppc64 -o aix_ppc64.o aix_ppc64.s
========
This as command appeared to be hung.
I ran this command without the -u options, and it worked:
========
$ /usr/bin/as -a64 -mppc64 -o aix_ppc64.o aix_ppc64.s
$ ls aix_ppc64.o
aix_ppc64.o
========
The man page for as, has this to say about the -u option:
========
-u Accepts an undefined symbol as an extern so that an error message is not
displayed. Otherwise, undefined symbols are flagged with error messages.
========
So I wonder how the as commands hangs when -u is provided, and works fine
without it ?
As as is internally called by gcc, how can I tell gcc to call this command
without -u? Does it even make sense (as calling as without -u may result in
build failures in other components)?
Has anyone seen this before?
Do you guys think there is some problem with the assembler?
Do you think I require a patch for the assembler? If yes, could you please
point me to a place from where I can get the patch for the assembler?
I will highly appriciate any help you guys may provide.
Thank you,
~ Urjit
