[cfe-dev] Undefined symbols for architecture x86_64 when compile newFrontendActionFactory with clang 5.0.

[彬杰 via cfe-dev]

My Code is : 
===============================================================================================
void *threadRun(void *arg)
{
    struct threadParam *param = (struct threadParam *) arg;
    ClangTool clangTool(*param->cdb, *param->taskList);
    pthread_mutex_lock(&Global::actionMutex);
    unique_ptr<FrontendActionFactory> factory = newFrontendActionFactory<GodEyesFrontendAction>(); // Error happens here
    ToolAction* action;
    if (factory != NULL) {
        action = factory.get();
    }
    pthread_mutex_unlock(&Global::actionMutex);
    if (factory != NULL) {
        clangTool.run(action);
    
    }
    return (void*)1;
}

===============================================================================================
it can compile and link well in clang 3.7, but when I upgrade clang to 5.0 ,  it link fails.  I don't know what's wrong with this;
Please help me out here.Any idea will be appreciated! thanks!!!
