[Flightgear-devel] Mac joysticks
I finally managed to get my FlightGear behaving itself last week - there are a few issues I want to investigate before I bring them up here, but one affected me almost immediately - the input code as it stands right now means Mac joysticks tend not to be recognised. There are two issues: firstly, when support was added in the XML joystick definitions for platform specific axis / button identifiers, a case was added for 'mac' as well as 'unix' and 'windows' - but most (none?) of the joystick files actually use this tag. Now, one option is to go around adding 'mac' tags, but at least for my SideWinder, the OS-X axis / button assignments match the Unix ones. I would be prepared to bet a small sum of money that most of the time, the assignments are going to match ... but of course I can't be sure until Mac users with some of the existing joysticks test this. (Knowing what happens with the logitech and thrustmaster sticks would be interesting) Anyway, I have a trivial patch to 'input.cxx' which adds in a fallback to 'unix' on OS-X; it works for me. The second issue is probably my fault, since I did the original code to add joystick support to PLIB on OS-X (but various people have fixed bugs since then). The code that reports the device name is only using the Product ID, and not the manufacturer ID as well. Hence, on OS-X, the name returned for my joystick is 'SideWinder Precision 2 Joystick', whereas on Linux it would be 'Microsoft SideWinder Precision 2 Joystick'. Obviously this is breaking the config lookup logic. I guess I should submit a patch to PLIB for this issue - in the short term I have just extended my joystick definition.

bool operator()( const string x, const string y) const
{
return your ordering;
}
Where your ordering can be written as
std::lexicographical_compare
( x.begin() , x.end() , y.begin() , y.end() , ICAOcode_char_lt() )
where ICAOcode_char_lt implements the ``less than'' relation for the
individual characters for your ICAO codes:
struct ICAOcode_char_lt {
bool operator()( char const x , char const y ) const {
// Numbers come after letters:
if( std::isalpha( x ) std::isdigit( y ) ) { return true ; }
// Upper-case only comparison:
return std::toupper( x ) std::toupper( y ) ;
}
} ;
(hope this relation is transitive---please check!)

[Flightgear-devel] Qt 4 will be GPLed for all supported systems
-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, I've just read at the Heise Newsticker, that Trolltech is planning to release the next version of Qt for all systems (including M$ Windows) under it's dual license. = We can start to use it!! :) The attached text (including the reasons their marketing people see for OSS to use it) was also posted there... CU, Christian Dear Qt User/Qt Customer: Trolltech is pleased to announce that we intend to make Qt 4 for Windows available under our successful dual licensing business model. This means that Open Source projects under the GNU GPL license will be able to target all major operating systems using Qt 4. We plan to release the Windows Open Source version of Qt at the same time as Qt 4. What dual licensing means = Qt's dual licensing model is based on the principle of fair exchange. If you are using Qt commercially - that is, for creating proprietary software for sale or use in a commercial setting - you must purchase a commercial license from Trolltech. Alternatively, if you wish to write Open Source software you can use the Open Source version of Qt, released under the GPL. If you use the Open Source version you must release your application and complete source code under the GPL as well. This model has proven successful for a number of leading companies such as MySQL and Sleepycat, and has been important to the success of Qt on the X11 and Mac OS X platforms. For more information on Trolltechs dual licensing business model, visit http://www.trolltech.com/company/model.html. What this means for Trolltech customers === The need for customers to hold commercial licenses for all commercial development will not change. However, the extension of the dual license model to Windows will mean that both the pool of available talent and the number of innovative Qt-based applications on Windows will increase. Also we expect that Open Source users will contribute valuable feedback and quality assurance for the Windows version of Qt, just like our X11 and Mac users have in the past. The commercial version of Qt will contain a number of product elements that only commercial license holders will have access to, including: - - Trolltech support - - The opportunity to purchase access to Qt Solutions - - Commercial compiler support - - Prebuilt Qt binaries (the GPL package is source only) - - Commercial database drivers Finally, we believe that Open Source users who have been exposed to Qt will choose the commercial version of Qt for their commercial work, thus boosting Trolltech's revenue and making more resources available for development and improvement of the product. What this means for the Open Source community = The Open Source movement has contributed huge amounts of innovative, highly useful software. Numerous well-known Open Source projects such as Apache, Mozilla/Firefox and KDE have helped redefine the landscape of computing and have propelled Open Source from a niche phenomenon into a mainstream movement. By making Qt available under the GPL license on Windows, Trolltech has given cross-platform Open Source projects the option of jump-starting their Windows development, using a mature, feature-rich framework that is consistent across platforms. Open Source developers can spend more time developing and refining functionality and less time on fixing and debugging underlying architecture. How Trolltech will enforce licensing We depend on revenue from the commercial version of Qt in order to develop and enhance new versions. It is therefore imperative that users of Qt understand our licensing and choose the correct license for each project. To determine which license you require, please visit http://www.trolltech.com/products/qt/licensing.html, or contact a Trolltech representative directly. We kindly request our customers and users to ensure that they are in possession of the appropriate number of commercial Qt licenses. It is possible to find out if an application has been created using Qt. Trolltech is prepared to take steps against misuse of the Open Source version for commercial development. Availability, timing and further information We plan to release the Windows Open Source version of Qt at the same time as the final release of Qt 4.0. For more information, please refer to the Windows Dual Licensing FAQ on http://www.trolltech.com/developer/faqs/duallicense.html Best regards, The Trolltech Team -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.0 (MingW32) iD8DBQFCB7ielhWtxOxWNFcRArtvAJwJB6iNXlAhwqsHvHT3Pz0ioyqYZwCeL3PE 64pWwTcBQnGVw1j/o1EXIz4= =Idq2 -END PGP SIGNATURE- ___ Flightgear-devel mailing list Flightgear-devel@flightgear.org http://mail.flightgear.org/mailman/listinfo/flightgear-devel

The C++ Programming language 3rd ed. tells me:
Basically you've got 2 options:
1 - create a class with the operator
class IACOcode
{
string the_code;
}
bool operator( const IACOcode a, const IACOcode b )
{
return your ordering;
}
mapIACOcode, ARP* apt_map;
2 - create a custom sort order
class IACOcode_compare
{
public:
bool operator()( const string x, const string y) const

}
mapstring, ARP*, IACOcode_compare apt_map;
Then you'll automatically get the desired result with your described lookup.
Thanks to everyone who replied. I can see how to do it now, but unfortuanately
it's now been complicated by the fact that the GPS unit appears to sometimes
consider letters before numbers (forward prediction of airports), but sometime
consider numbers before letters (scanning through the waypoint lists). It
seems that associative containers need the comparison operator specified at
creation (for good reason when I think about it) so I guess I'll just carry on
with my hack to avoid storing the data in memory twice.

Yes, John Wojnaroski (retired military pilot and FG contributor), Jim Brennan (retired 747 pilot), Alex Perry (FG contributor, pilot, FAA safety inspector, phd, etc), and I will be at SCALE this coming weekend in the LA convention center. John is building a full 747 cockpit simulator and basing his efforts largely on FlightGear, OpenGC, linux, and other open-source software. If anyone else is in the area, please stop by and introduce yourself; we'd love to meet you. There is a short note on my home page as Erik pointed out: http://www.flightgear.org/~curt/ There is also an entry on the FG events page: http://www.flightgear.org/events.html#scale05 Finally, there is a little bit larger description of the project with a few pictures here: http://www.flightgear.org/Projects/747-JW/ I hope to have a few more pictures and info after the event is finished. John will be the first to point out the flaws and shortcomings of his sim (it's a lot of work to fully replicate a 747 cockpit and he's not quite done yet.) But to the average flight sim enthusiast or aviation enthusiast (and hopefully to the average linux geek) this is going to be a really awsome demo.
