Thanks for filling out the PRF!

Even though x.5 was the last major DOC Group release, I think
you will have better luck with either the latest beta release
(currently x.5.9) or the latest OCI TAO 1.5a patched release,
available from:

It certainly looks like either you are not linking with the
TAO_AnyTypeCode library, or that library was not built.
To tell the truth, I'm not sure that library had been split
out separately in TAO 1.5.  The later releases listed above
have it as a separate library.  If your server project (in your
.mpc file) inherits from the "portableserver" (or "taoserver")
base project, the TAO_AnyTypeCode library will be included in
the list of libraries with which to link.

I can't speak to the TPG's example, but an updated version of
the Getting Started example from the OCI TAO Developer's Guide
(complete source code and .mpc file) is included in the OCI
TAO 1.5a release, in the
$TAO_ROOT/DevGuideExamples/GettingStarted/ directory.
It should build out of the box with no problems with TAO 1.5a
latest patched release.

I recommend following the build instructions in the TAO FAQ:
