| Hi Greg,
Many thanks indeed for your informative email and ongoing interest. I feel much better informed and also quite sheepish about the amount of work needed for the organisational workarounds & modifications to Steve's source that will be needed. I will bear this in mind as I work on the Synthesizer port. I have certainly found getting my mind around the full intricacies of Monet structure quite a challenge, and can see the truth of what you say.
Your comment about needing to set up a library is well taken. You and Steve would be the best people to work out what is needed. At this stage, I think my contribution might be counterproductive ;-) I don't think Steve is likely to be able to fit too much into his schedule right now, but I am sure he is still interested and may at least be able to provide comments and suggestions.

All good wishes & many thanks.

The problem with the GNUstep port has been due to a number of factors (not in any particular order):1) Xcode has ability to allow you to pull in code from any number of places to build your application. Using this ability, you can have the code placed anywhere in your project folder. In the case of GNUspeech, there is much shared code between Monet and the tube model tool using this facility of Xcode. Much of this code, in my opinion, should be made into a library so that we have a more traditional code organization and don't have to depend on build processes that are only present Mac OS X. To bridge this gap, I've had to implement some copying in the makefiles, which is something of a kludge.2) Up until now the GCC project has not had ObjC++, a necessity for integrating with C++ libraries and code with ObjC code. This feature is present in GCC 4.1 (which is currently not released yet) and it has been anticipated in GNUstep for some time.3) GNUspeech uses CoreAudio, which is not considered to be part of Cocoa. As a result, I have had to look into other ways to get this code working using NSSound on GNUstep without, of course, disturbing the code that has been written and works properly for Mac OS X.GNUstep's charter (http://www.gnustep.org/information/aboutGNUstep.html) is to provide a Cocoa compatible library for developers to port thier applications. GNUstep does provide this, as well as many extensions. GNUstep does not, however, promise perfect compatibility with Xcode or every library which Apple creates that falls outside of Cocoa (CoreData, CoreAudio...), in GNUspeech's case CoreAudio, that a developer might use. GNUspeech shouldn't be used as a gauge to determine GNUstep's completeness since GNUspeech currently uses many features of Mac OS X, which fall outside of GNUstep's charter. GNUstep *is* complete, the port of GNUspeech is not. :)
OK, fair comment. I was vaguely aware of these differences but it is nice to have the situation clarified. I had originally thought GNUspeech might be a nice complex test for GNUstep. Obviously it helps, but testing "completeness" is not the issue. This is my fault, for lack of time to devote sufficient effort to it.
Hopefully, in the coming weeks I will be able to find more time to contribute to GNUspeech and make Monet work properly on Linux/BSD boxes.
Many thanks indeed. I can't think of anyone better qualified to undertake this task and your commitment is very much appreciated.

Sorry! I am the one sending confusing messages. It is not clear
that GnuStep is complete enough yet to do Monet. However, Mac's
"Cocoa" is so close to GnuStep that I am working on a Mac using Xcode
2.2 and Cocoa on the grounds that when GnuStep is complete, the port
should be almost a matter of re-compiling. Greg Casamento has
already done some of the additional conditional compilation code on
the Monet system that was ported to Mac by Steve Nygard to move
towards allowing the source to compile on either system (single
source, and simply set a condition so it compiles for whichever you
want). That is the source that's on the savannah gnuspeech site. To
some extent, the way to see how complete GnuStep is we have to see
how well Monet compiles under it, which is what Greg is supposedly
doing (Is that accurate Greg?)
I did read somewhere that there is a straight Objective C system that
runs under Linux, but it may simply be someone referring to GnuStep.
A non-GnuStep Objective C would probably be useful for non-
interactive stuff, but if it didn't meet the GnuStep/Cocoa standards,
it would not help with the interactive-intensive stuff. However,
real-time Monet doesn't need all the interactive stuff, but it will
be quite an exercise stripping out what's needed from the existing
Monet for the "real-time Monet" package.
I haven't heard from Greg for a while. He's a GnuStep "guru" -- he's
worked on it extensively.
I am porting "Synthesizer" because it is a basic tool for improving
speech quality (something I am very interested in doing) and
developing datasets for new languages (I've had enquiries), and it is
of interest to you, of course). It is also something to get me
working towards a real-time Monet, and become familiar with
everything I need to be familiar with to work more effectively on any
part of the overall system.
I notice that your reply is a reply to a message I sent to Rob Brewer.

Cocoa and GnuStep are very similar by design. GnuStep is (AFAIK) not
yet complete.

See above.
