[FlightGear-Devel readers: this is another installment in my quest to get FlightGear compiled under Mac OS X. I now have a good lead on the final link failure, I think. If you have any knowledge of linker naming conventions, symbol tables, and the like, I would appreciate your comments. Thanks. P.S. Everything is being built from CVS.]
Previous make's were failing, unable to find gen_leaf or ssgVtxTable::ssgVtxTable. Sometime recently the call to gen_leaf was removed from the CVS code. Instead, three other symbols are now not being found. Here's the final make command along with output: david@Cynosure ~/FlightGear/src/main $ make g++ -DPKGLIBDIR=\"/Users/david/lib/FlightGear\" -g -O2 -D_REENTRANT -L/Users/david/lib -L/usr/X11R6/lib -o fgfs main.o fg_commands.o fg_init.o fg_io.o fg_props.o fgfs.o globals.o logger.o options.o splash.o util.o viewer.o viewmgr.o location.o ../../src/Aircraft/libAircraft.a ../../src/ATC/libATC.a ../../src/Autopilot/libAutopilot.a ../../src/Cockpit/libCockpit.a ../../src/Cockpit/built_in/libBuilt_in.a ../../src/Controls/libControls.a ../../src/FDM/libFlight.a ../../src/FDM/Balloon/libBalloon.a ../../src/FDM/ExternalNet/libExternalNet.a ../../src/FDM/JSBSim/libJSBSim.a ../../src/FDM/YASim/libYASim.a ../../src/FDM/JSBSim/filtersjb/libfiltersjb.a ../../src/FDM/LaRCsim/libLaRCsim.a ../../src/FDM/UIUCModel/libUIUCModel.a ../../src/GUI/libGUI.a ../../src/Input/libInput.a ../../src/Instrumentation/libInstrumentation.a ../../src/Model/libModel.a ../../src/Navaids/libNavaids.a ../../src/Scenery/libScenery.a ../../src/Scripting/libScripting.a ../../src/Sound/libSound.a ../../src/Airports/libAirports.a ../../src/Network/libNetwork.a ../../src/NetworkOLK/libNetworkOLK.a ../../src/Objects/libObjects.a ../../src/Systems/libSystems.a ../../src/Time/libTime.a ../../src/Environment/libEnvironment.a -lsgroute -lsgsky -lsgephem -lsgtiming -lsgio -lsgscreen -lsgmath -lsgbucket -lsgdebug -lsgmagvar -lsgmisc -lsgxml -lsgserial -lsgthreads -lplibpu -lplibfnt -lplibjs -lplibnet -lplibssg -lplibsg -lplibul -lplibpsl -lmk4 -lz -lpthread -lm -framework GLUT -framework OpenGL -framework Carbon -lobjc -lplibsl -lplibsm -framework IOKit -framework CoreFoundation -lm ld: warning table of contents of library: ../../src/FDM/JSBSim/libJSBSim.a not sorted slower link editing will result (use the ranlib(1) -s option) ld: Undefined symbols: trTileSize(_TRctx*, long, long, long) trImageSize(_TRctx*, long, long) trTileBuffer(_TRctx*, unsigned long, unsigned long, void*) ssgVtxTable::ssgVtxTable[in-charge](unsigned, ssgVertexArray*, ssgNormalArray*, ssgTexCoordArray*, ssgColourArray*) make: *** [fgfs] Error 1 I have been using nm to poke around and believe I know what is going on, even if I don't know how to fix it: david@Cynosure ~ $ nm -o lib/libsgscreen.a FlightGear/src/GUI/gui_funcs.o | egrep 'trTileSize|trImageSize|trTileBuffer' lib/libsgscreen.a:tr.o:00001564 S _Z10trTileSizeP6_TRctxiii.eh lib/libsgscreen.a:tr.o:0000158c S _Z11trImageSizeP6_TRctxii.eh lib/libsgscreen.a:tr.o:000001d4 T __Z10trTileSizeP6_TRctxiii FlightGear/src/GUI/gui_funcs.o: U __Z10trTileSizeP6_TRctxlll lib/libsgscreen.a:tr.o:000003c8 T __Z11trImageSizeP6_TRctxii FlightGear/src/GUI/gui_funcs.o: U __Z11trImageSizeP6_TRctxll lib/libsgscreen.a:tr.o:0000036c T __Z12trTileBufferP6_TRctxjjPv FlightGear/src/GUI/gui_funcs.o: U __Z12trTileBufferP6_TRctxmmPv If you look closely at the "T" lines and the "U" lines, you will see that the symbol names do not match! No wonder the final link fails. I guess I need some way to get the compiler to generate the same symbol names. The other unfound symbol, ssgVtxTable::ssgVtxTable[in-charge] is trickier, but I found it. The sad thing is, the symbol names match, so I don't know why the symbol is not found. david@Cynosure ~ $ nm `find plib -type f -name \*.o -print` | egrep ssgVtxTable | egrep '^.........[TU]' | sort +0.11 | uniq > foo david@Cynosure ~ $ nm `find FlightGear -type f -name \*.o -print` | egrep ssgVtxTable | egrep '^.........[TU]' | sort +0.11 | uniq > bar david@Cynosure ~ $ cat bar U __ZN11ssgVtxTableC1EmP14ssgVertexArrayP14ssgNormalArrayP16ssgTexCoordArrayP14ssgColourArray david@Cynosure ~ $ egrep __ZN11ssgVtxTableC1EmP14ssgVertexArrayP14ssgNormalArrayP16ssgTexCoordArrayP14ssgColourArray foo U __ZN11ssgVtxTableC1EmP14ssgVertexArrayP14ssgNormalArrayP16ssgTexCoordArrayP14ssgColourArray 0000050c T __ZN11ssgVtxTableC1EmP14ssgVertexArrayP14ssgNormalArrayP16ssgTexCoordArrayP14ssgColourArray Regards, David K.
