Transplanting method for car-mounted information system development platform functional module

Abstract

The invention provides a transplanting method for a car-mounted information system development platform functional module. The method comprises the steps that the functional module is independently stored in a first folder, and the first folder is processed to obtain a corresponding first static library file; the first static library file is added into a compiling link in newly-developed project engineering of a Sunplus platform; a C standard library is newly added to the Sunplus platform, and conflicting functions in a C function library and the C standard library supported by the Sunplus platform are processed; a C++ standard library is newly added to the Sunplus platform. By means of the technical scheme, the developed C / C++ function module on other platforms can be transplanted into the newly-developed project engineering of the Sunplus platform.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method for transplanting functional modules of a vehicle information system development platform. Background technique [0002] At present, the in-vehicle information system has gradually become a standard part of the car, bringing convenience to people's car life. With more and more manufacturers developing in-vehicle information systems, the competition is becoming increasingly fierce. Not only the cost has become the focus of competition among manufacturers, but the development speed has also become an important factor related to the success or failure of a product. Going to market as soon as possible is a weapon for manufacturers to win. [0003] Currently, there are various development platforms for in-vehicle information systems, such as MTK MediaTek development platform, Sunplus Sunplus development platform, and so on. Usually, in-vehicle information system technicia...

Problems solved by technology

[0005] However, the inventor found in the research that there are differences between the C language function library of the Sunplus platform and the standard library functions based on the ANSI / ISO C language, such as different storage or implementation methods, or different functions for functions with the same name. In addition, the Sunplus platform does not Contains C++ language standard library, so there are many problems in transplanting functional modules (program codes or files containing codes that realize a certain function in software project engineering) that have been developed based on C / C++ language on other platforms to the Sunplus platform. For example, it cannot be compiled, or even if it can be compiled, it may not achieve the intended function

The usual choice of traditional technology is to redevelop a functional module to realize a certain function on the Sunplus platform, which will lead to a long development cycle and affect the time to market of the product
