我不知道如何使结构或对象成为线程私有(private)的，我正在做的事情会产生错误:structpoint2d{intx;inty;point2d(){x=0;y=0;}//copyconstructorpoint2d(point2d&p){x=p.x;y=p.y;}};我声明了一个静态结构并尝试使它们成为线程私有(private)的staticpoint2dmyPoint;#pragmaompthreadprivate(myPoint)它会产生一个错误:errorC3057:'myPoint':dynamicinitializationof'threadprivate'symbols

我的已知数据是我的当前位置(GeoPoint)和以米为单位的半径。我想根据map投影和半径在当前位置周围画圈。我的mapView叠加层确实覆盖了绘图方法，例如@Overridepublicvoiddraw(Canvascanvas,MapViewmapView,booleanshadow){Projectionprojection=mapView.getProjection();GeoPointmyLocationGeoPoint=getLocationGeoPointFromSomeSource();PointmyPoint=newPoint();projection.toPixel

我正在尝试将向量变量放入Google的Go编程语言的结构中。这是我目前所拥有的:想要:typePointstruct{x,yint}typemyStructstruct{myVectorInsideStructvector;}funcmain(){myMyStruct:=myStruct{vector.New(0)};myPoint:=Point{2,3};myMyStruct.myVectorInsideStruct.Push(myPoint);}有:typePointstruct{x,yint}funcmain(){myVector:=vector.New(0);myPoint:=
