[gme-users] invoking interpreters

Sun Dec 16 08:42:26 CST 2012

Sumit,

I'm not really sure what you want here, as you've only provided the
"how" not the "why".

If you really need static linking of Udm, you should download the Udm
source code and link with the .libs the build produces. These .libs are
no longer distributed, as they are large, complicate debugging, and
require Udm users to install all of the libraries Udm depends on. Why
wouldn't you use dlls?

If you need an exe to talk to GME, either create the GME COM object
yourself via CoCreateInstance("GME.Application") (see GME.idl), or write
an interpreter with some sort of IPC mechanism (sockets, named pipes,
etc) that will talk to your exe.

It looks like static linking is the only real issue.  A "normal" UDM
interpreter interacts with GME to process mga files via GME's COM
interface.  UDM hides most of the details behind the scenes so you don't
have to do all of the COM setup, transaction management, and so forth.
The UDM/GME glue code created by the Udm interpreter wizard has a lot of
the details if you want to take them apart and manage all of that
yourself.

Now - the question for the list - how hard is it to get a
statically-linkable version of the UDM libraries (or is it even
possible)?

Joe,

Thanks. I will try out what you suggest but what I am looking for is an
UDM-based statically-linked executable (interpreter) that interacts with
a live (running) instance of GME. How does one connect to a GME
application processing an "mga" file from a static executable?

Thanks,
Sumit

Sumit,

The chief advantage with UDM is that you can use the XML backend to
write
standalone interpreters that are completely independent of GME.  The Udm
installation comes with a utility called UdmCopy that can convert a GME
model into the equivalent XML digestable by Udm.  Your interpreter will
need to include the Udm-generated code, and either include the generated
xsd file in your distribution or else compile it into the code (see the
Udm
command-line options).  Instead of all of the COM infrastructure that
you
used to integrate your interpreter code into GME, you can simply write a
main function that loads the specified model file and invokes your
logic.
 The only tricks are to link against the UDM library, and to make sure
you
commit model changes before closing.  UdmCopy and Udm should both
provide
command-line help when run from the prompt.

Is that what you're after?
