[Flightgear-devel] FGFS final link fails: _imp__pthread symbols not found
I've tried compiling fgfs from cvs on mingw again. There are various little changes which I'll roll up at some point (as in, when it's working ;). However, there's an odd problem I'm getting at final link: g++ -DPKGLIBDIR=\/point/share/FlightGear\ -g -O2 -D_REENTRANT -L/point/lib -o fgfs.exe bootstrap.o ../../src/Main/libMain.a ../../src/Aircraft/libAircraft.a ../../src/ATC/libATC.a ../../src/Cockpit/libCockpit.a ../../src/Cockpit/built_i n/libBuilt_in.a ../../src/Controls/libControls.a ../../src/FDM/libFlight.a ../.. /src/FDM/Balloon/libBalloon.a ../../src/FDM/ExternalNet/libExternalNet.a ../../s rc/FDM/ExternalPipe/libExternalPipe.a ../../src/FDM/JSBSim/libJSBSim.a ../../src /FDM/YASim/libYASim.a ../../src/FDM/JSBSim/filtersjb/libfiltersjb.a ../../src/FD M/LaRCsim/libLaRCsim.a ../../src/FDM/UIUCModel/libUIUCModel.a ../../src/FDM/SP/l ibSPFDM.a ../../src/GUI/libGUI.a ../../src/Autopilot/libAutopilot.a ../../src/In put/libInput.a ../../src/Instrumentation/libInstrumentation.a ../../src/Model/li bModel.a ../../src/AIModel/libAIModel.a ../../src/Network/libNetwork.a ../../src /Navaids/libNavaids.a ../../src/Scenery/libScenery.a ../../src/Scripting/libScri pting.a ../../src/Sound/libSound.a ../../src/Airports/libAirports.a ../../src/R eplay/libReplay.a ../../src/Systems/libSystems.a ../../src/Time/libTime.a ../../ src/Traffic/libTraffic.a ../../src/Environment/libEnvironment.a -lsgclouds3d -lsgroute -lsgsky -lsgsound -lsgephem -lsgmaterial -lsgtgdb -lsgmodel -lsgtiming -lsgio -lsgscreen -lsgmath -lsgbucket -lsgprops -lsgdebug -lsgmagvar -lsgmisc -lsgnasal -lsgxml -lsgsound -lsgserial -lsgstructure -lsgenvironment -lsgthreads -lplibpu -lplibfnt -lplibjs -lplibnet -lplibssg -lplibsg -lplibul -lz -lglut32 -lglu32 -lopengl32 -luser32 -lgdi32 -lALut -lopenal32 -lws2_32 -lwinmm -ldsound -ldxguid -lole32 Warning: .drectve `-defaultlib:uuid.lib ' unrecognized Warning: .drectve `-defaultlib:uuid.lib ' unrecognized ../../src/Scenery/libScenery.a(tilemgr.o)(.text+0xb7a): In function `ZN9FGTileMgr16all_queues_emptyEv': C:/msys/1.0/point/include/simgear/threads/SGThread.hxx:232: undefined reference to `_imp__pthread_mutex_lock' ../../src/Scenery/libScenery.a(tilemgr.o)(.text+0xb9e):C:/msys/1.0/point/include/simgear/threads/SGThread.hxx:238: undefined reference to `_imp__pthread_mutex_unlock' This continues for many screens (and for many other calls - it's not just mutex related). The error is the same whether or not I add -lpthread to the command. Investigating the pthread library, all the calls are present in the form _pthread (_pthread_mutex_lock, _pthread_mutex_unlock, _pthread_cond_destroy etc), but none with the _imp_ prefix. gcc 3.4.2 (mingw-special) with win32 thread model. Does anybody have any ideas about what is going wrong?
