Re: [Flightgear-devel] CVS FlightGear and plib 1.6 (was Mac OS X: at a loss)

[Jonathan Polley]

Hmm, that's odd. Out of the box, the version of the Mac joystick code that is in CVS does not compile. As I reported to the plib group, if I incorporate the non-CVS versions of jsMacOSX.cxx and js.h, I get the following errors in the FlightGear joystick code:

ld: Undefined symbols:
jsJoystick::read(int*, float*)
_CFArrayApplyFunction
_CFArrayGetCount
_CFArrayGetTypeID
_CFDictionaryGetTypeID
_CFDictionaryGetValue
_CFGetTypeID
_CFNumberGetValue
_CFRelease
_CFStringGetCString
_CFStringGetSystemEncoding
_CFUUIDGetConstantUUIDWithBytes
_CFUUIDGetUUIDBytes
_IOCreatePlugInInterfaceForService
_IOIteratorNext
_IOIteratorReset
_IOMasterPort
_IOObjectRelease
_IORegistryEntryCreateCFProperties
_IOServiceGetMatchingServices
_IOServiceMatching
___CFStringMakeConstantString
_kCFAllocatorDefault

I've been trying to help David Drum get his FlightGear to build and he discovered that adding -framework Carbon to the Makefile reduces the link errors down to

ld: /Users/david/FlightGear/FlightGear-CVS/lib/libplibjs.a(jsMacOSX.o) illegal reference to symbol: _IOCreatePlugInInterfaceForService defined in indirectly referenced dynamic library /System/Library/Frameworks/IOKit.framework/Versions/A/IOKit

If I restore the plib code back to 1.6, then I can finally get a link. Since I don't use a joystick, that works for me.

The solution, for me at least, was to revert back to the CVS version of plib and overwrite the src/js directory with plib 1.6's (as the current Mac joystick code is in a major broken state). Hopefully, David will have a chance to see if it fixes his build problem as >> well.

Err, the JS code is fine for me now (and for Ima too, I think), once you replace js.h and jsMacOSX.cxx with the ones I posted to plib-devel a few days ago. If these do not fix any problems you're having, then **please** post something to plib-devel or email me directly. Since getting things checked into plib CVS seems to be rather slow, I'd rather get the files confirmed working for people before requesting another commit.

FWIW, CVS of 'everything' is working on my iBook, updated today, but I have a bunch of local mods to simgear/flightgear (in addition to the plib JS updates) : let me know if you want them. (I'll start feeding them to Curt / David soonish anyway I think)
