Abstract: A processing program, apparatus and method wherein each component has version information showing the version of the component and a version compatible information table showing with which one of the past self versions the component has a compatibility. Information showing with which version there is the compatibility or information with which version range there is the compatibility is shown in the version compatible information table. When the reference destination component is referred to from the reference source component, the presence or absence of the compatibility between the version designated by the reference source component and the version of the reference destination component is checked by using the version compatible information table. If a plurality of compatible components exist, the component of the latest version is selected as a reference destination component.

Abstract: It is an object to shorten a time required for a processing of linking components and to reduce the amount of a memory to be used during the linkage. When creating a component to be referred to another component, a declaration of a symbol in a source file is converted into an original symbol name through a compile processing to be caused to correspond to a symbol value to be an offset address in an object file. When creating a component to be a referent, a symbol information table in which the original symbol name is replaced with a symbol ID to be caused to correspond to the symbol value. Moreover, the original symbol name and the symbol ID are caused to correspond to each other so that an external symbol information file is created. In a component to be a reference source, the original symbol name referring to another component is replaced with a pair of the component ID and the symbol ID by using the file. Thus, a symbol reference information table is created.

Abstract: During the process of creating a component to be referred to by another component, a declaration of a symbol in a source file is converted into an original symbol name through a compile process. A symbol information table is created in which the original symbol name is replaced with a symbol ID, which corresponds to the symbol value. Moreover, the original symbol name and the symbol ID correspond to each other so that an external symbol information file is created. When a component is used as a reference source, the original symbol name referring to another component is replaced with a pair of the component ID and the symbol ID using a file. Thus, a symbol reference information table is created. Information about the linkage of the components to be the reference source and the referent are collated by using the symbol ID based on the table.

Abstract: A trouble of a system which is caused due to a difference of versions of components which are loaded is avoided. Each component has version information showing the version of the component itself and a version compatible information table 5 showing with which one of the past self versions the component has a compatibility. Information showing with which version there is the compatibility or information with which version range there is the compatibility is shown in the version compatible information table. When the reference destination component is referred to from the reference source component, the presence or absence of the compatibility between the version designated by the reference source component and the version of the reference destination component is checked by using the version compatible information table 5. If a plurality of compatible components exist, the component of the latest version is selected as a reference destination component.
