I saw that; what I don't understand is why it doesn't link to -ldb1.

bash-2.04$ ls -l /lib/libdb*

Oh, doesn't ld know about versioned .so's?  Hmmm ....

bash-2.04$ cat >/tmp/test.c <<EOT 
> #include <db.h>
> int main () { dbopen(0,0,0,0,0); }
bash-2.04$ gcc -o /tmp/test -ldb1 /tmp/test.c
/usr/bin/ld: cannot find -ldb1
collect2: ld returned 1 exit status
bash-2.04$ su -c 'ln -s /lib/'
bash-2.04$ gcc -o /tmp/test -ldb1 /tmp/test.c

Aarrgh.  Debian, bletch.  OTOH, glibc no longer provides db (see
attached FAQ).  Maybe it's time to migrate Coda?  Or is Linux the only
system where db 1.85 is being phased out?

2.31.   What happened to the Berkeley DB libraries?  Can I still use db
        in /etc/nsswitch.conf?

{AJ} Due to too many incompatible changes in disk layout and API of Berkeley
DB and a too tight coupling of libc and libdb, the db library has been
removed completely from glibc 2.2.  The only place that really used the
Berkeley DB was the NSS db module.

The NSS db module has been rewritten to support a number of different
versions of Berkeley DB for the NSS db module.  Currently the releases 2.x
and 3.x of Berkeley DB are supported.  The older db 1.85 library is not
supported.  You can use the version from glibc 2.1.x or download a version
from Sleepycat Software (  The library has to be
compiled as shared library and installed in the system lib directory
(normally /lib).  The library needs to have a special soname to be found by
the NSS module.

If public structures change in a new Berkeley db release, this needs to be
reflected in glibc.

Currently the code searches for libraries with a soname of ""
(that's the name from db 2.4.14 which comes with glibc 2.1.x) and
"" (the name used by db 3.0.55 as default).
