[Flightgear-devel] A SenecaII for FlightGear: first version available
Hi all, it's been a while, since I announced the model for a Seneca. It is a *LOT* more work, than I expected it to be so it took a lot longer than I thought. But I think I can show you what I have so far: http://www.t3r.de/fg/seneca/ The site gives you a something to look at and a downloadable version. This should be considered a before-pre-alpha-preview release with lots of work-in-progress and under-construction items. But there is also a lot to see already. If anybody wants to give it a try, I whould be happy to get some comments. Greetings, Torsten --- Using Tomcat but need to do more? Need to support web services, security?

[Flightgear-devel] [PATCH] simgear patch that fixes my whole last no sound fix
In simgear/sound/soundmgr_openal.cxx, working is never set to true for
openal/alut version = 1 if it worked.
This should fix my last fix.
And please make sure to reapply the fix in FGFX::play_message before
testing/committing.
Thanks.

Re: [Flightgear-devel] Generic Protocol (generic.cxx etc) - Binary Mode
Thanks Erik,
Here is the patch. Let me know what needs to be changed, fixed, or
refactored before it can go into CVS. Note that at this point, the
binary protocol is output only.
Also attached is a really simple protocol to test the patch
(bintest.xml). Run FGFS with:
$ fgfs ... --generic=file,out,24,bintest_out,bintest
As well, there is a Python script (sorry, the script is a horribly dirty
hack) to decode and print the results. Execute it with:
$ python test_decode.py
To do list for the generic binary support:
* use ntohl() etc to make the protocol independent of host endianess.
* add CRC checksum as a possible packet footer
* add binary input support
* test thoroughly
Cheers,
Hugo Vincent
