perl5.001m use Berkeley DB on AIX 3.2.5 problem

I built Berkeley DB on my machine and re-configured perl. But it failed
the test after the build:

$ make test
....
op/write.......ok
lib/anydbm.....FAILED on test 0
lib/bigint.....ok
lib/bigintpm...ok
lib/db-btree...FAILED on test 0
lib/db-hash....FAILED on test 0
lib/db-recno...FAILED on test 0
lib/english....ok
lib/gdbm.......ok
lib/ndbm.......ok
lib/odbm.......FAILED on test 0
lib/posix......FAILED on test 0
lib/sdbm.......FAILED on test 0
lib/soundex....ok
Failed 7/90 tests, 92.22% okay.

Anyone experience this? Could there be a problem if the libdb.a is built
without the -fpic option? Thanks for your time...

Hmm. Looks like *none* of the dynamic loading works. (I'll presume you
just don't have gdbm and ndbm, so the tests don't even try to run.)
Note that the lib/sdbm.t and lib/posix.t tests failed too. Try running
them by themselves, e.g.
cd t
./perl lib/sdbm.t
and see what happens.

Does dynamic loading with gcc even work on AIX? If it doesn't, and you
must use gcc, then I'd suggest
rm config.sh
sh Configure -Uusedl
to build a perl without dyanmic loading.

Hope this helps,

I dont know. Could someone clarify this?

I really dont have to use gcc to build perl5 on AIX. The reason I
used it are: (1) I used gcc to build perl5 on all the other 5 Unix
platforms (osf, ultrix, sunos, solaris, and hpux). (2) this is a
rental machine and the only compiler(s) are those come with Aix 3.2
base system. The cc output: XL C Compiler Version 1.3.0.0. Is this
good enough to build perl5 with dynamic linking?

Andy> Hope this helps,

Thanks for your quick response.

Thanks for the tip, it WORKS!! (I didnt build Tk so dont know if there
will be problem). The way I set it up are:

[build perl5.001m on AIX 3.2.5 with gcc 2.6.3]
* set gcc option to 'none', i.e., neither -g nor -O
* add '-Xlinker' ahead of "-bE:perl.exp"

Maybe this can be added to either perl Configure or the FAQ?
