Summary: Problem building site package bsddb3 on AIX

Initial Comment:
Help.  Trying to build and install bsddb3-4.1.3 on AIX 
4.3.2.  Setup.py produce:

cc -DNDEBUG -g -O3 -Wall -Wstrict-prototypes -
I/mksDev/local/BerkeleyDB.4.1.25/include -
I/mksDev/local/include/python2.2 -c extsrc/_bsddb.c -o 
build/temp.aix-4.3-2.2/_bsddb.o

which the -W options are not valid with IBM's version 5 
compiler.  Removed the -W options and was able to 
compile _bsddb.o.

Linker runs next with:

/usr/local/lib/python2.2/config/ld_so_aix cc -
bI:/usr/local/lib/python2.2/config/python.exp 
build/temp.aix-4.3-2.2/_bsddb.o -
L/mksDev/local/BerkeleyDB.4.1.25/lib -ldb -o build/lib.aix-
4.3-2.2/bsddb3/_bsddb.so

which uses the wrong prefix, replaced it with:

/mksDev/local/lib/python2.2/config/ld_so_aix cc -
bI:/mksDev/local/lib/python2.2/config/python.exp 
build/temp.aix-4.3-2.2/_bsddb.o -
L/mksDev/local/BerkeleyDB.4.1.25/lib -ldb -o build/lib.aix-
4.3-2.2/bsddb3/_bsddb.so

now I get:

ld: 0711-317 ERROR: Undefined

ld: 0711-345 Use the -bloadmap or -bnoquiet option to

I could really use some help here.  I have successfully 
build the bsddb3 before with a prior version.

Thanks

Finding BerkelyDB in other location than the standard
install locations is deliberately not supported in setup.py;
you need to edit Modules/Setup for non-standard installations.

As for the original bug: That looks like a BerkeleyDB or AIX
problem to me. Specifying -pthread should not be needed when
linking bsddb.so, instead, libbsdb-4.1.3 should be
self-contained. 

Did you install BerkeleyDB with --enable-shared? If not:
linking static libraries to extension modules is not
supported in setup.py; you have to edit Modules/Setup for
such an installation (on some systems, this is not supported
at all, as the system disallows non-PIC code in shared
libraries).

Also, the 2.2 bsddbmodule.c is not longer recommended for
2.3. So I'm closing this as Won't fix; AIX experts may still
step forward and provide patches in that area.

Thanks for the reply.

Yes, Python 2.2.x runs fine on AIX 4.3.2.  Been using it on aix 
since about March of 2002.  Recently upgraded to 2.2.2.

Finally figured out to add the -lpthread option last night.  
bsddb3-4.1.3 now compliles fine on AIX 4.3.2.  All tests 
passed as well.  

Had to run the complier and linker manually.  DistUtils needs 
some work with --prefix option if folks are going to use it for 
distributing python modules.

Have you got Python 2.2.x to work on AIX 4.2 or greater?  I
don't believe it works out of the box.

It appears that bsddb requires the pthread library.  You
will need to modify setup.py to add pthread to dblib around
line 444.
