    I'm trying to build simple application using physX. I'm using linux 3.2 beta2 version of SDK.
    I have added these libs to my project:

    -lpthread\
    -lLowLevel\
    -lLowLevelCloth\
    -lPhysX3\
    -lPhysX3CharacterKinematic\
    -lPhysX3Common\
    -lPhysX3Cooking\
    -lPhysX3Extensions\
    -lPhysX3Vehicle\
    -lPhysXProfileSDK\
    -lPvdRuntime\
    -lPxTask\
    -lPxTask\
    -lRepXUpgrader3\
    -lSceneQuery\
    -lSimulationController

    But I get this error during compilation:

    Any suggestions would be great

    Hi,

    Could you please provide a sample source and makefiles for us to reproduce that error? You could be missing some paths or defines.

    Thanks,
    Sheikh

    I'm using QT Creator. (But Ive tried code::blocks and got the same) Sample code in tar in attachment

    I've set same libs and g++ flags, but it doesn't help :(

    I found the solution.
    This error occurs by cross-dependencies between Physx libs.
    I use -Wl flag for that. And project was successfully build ^_^

    Correct libs definition in makefile:

    LIBS += -Wl,--start-group -lrt\
    -lPhysX3Common\
    -lPvdRuntime\
    -lSimulationController\
    -lSceneQuery\
    -lLowLevel\
    -lLowLevelCloth\
    -lPhysX3\
    -lPhysX3Vehicle\
    -lPhysX3Cooking\
    -lPhysX3Extensions\
    -lPhysX3CharacterKinematic\
    -lRepX3\
    -lRepXUpgrader3\
    -lPhysXProfileSDK\
    -lPxTask -Wl,--end-group


    Thx!

    p.s. in linux SDK lib -lXxf86vm is missed in makefile for Samples
