Implementation method of cross-platform ABI compatible C + + component framework

Abstract

The embodiment of the invention provides an implementation method of a cross-platform ABI compatible C + + component framework. According to the method, the cross-platform (i.e., irrelevant to an operating system) ABI compatible component framework implemented by adopting modern C + + is provided. The ABI compatible component framework is based on an ABI interface type with stable layout, a proprietary type system is constructed, then a corresponding relation between the ABI interface type in the proprietary system and an implementation function is constructed, and according to the corresponding relation, a compiler in an operating system calls the function of the ABI interface type according to the corresponding relation when compiling a C + + program. The ABI interface type has stability, and a bottom layer system is constructed in the service life and then associated with functions in a C + + program, so that layouts in executable files generated by compilers of different versions are not changed, namely the layouts are compatible with the executable files.

Description

technical field [0001] The embodiment of the present invention relates to the field of computer technology, in particular to a method for realizing a cross-platform ABI compatible C++ component framework. Background technique [0002] C++'s ABI (Application Binary Interface - C++ Application Binary Interface) defines the low-level interface specification for calls between the C++ language and the operating system. It describes a data type's memory layout, exported symbols, and calling convention. ABI compatibility means that two different versions of C++ compilers compile the same code, and the generated executable files are compatible with each other, and can be correctly called by a third party without recompiling the source code in a third-party configuration environment. Because the C++ standard library implementations provided by major manufacturers are almost incompatible, the ABIs of executable files generated by compiling the same code with different manufacturers a...

Problems solved by technology

[0004] However, the above two methods still have the following problems: First, the complexity is high. In order to avoid ABI compatibility issues, Windows requires users to use complex COM frameworks, so that standard C++ types cannot be used as external interfaces, and C++ is lost. part of language

The second is non-cross-platform. The existing solutions adopt their own platform-related solutions for mainstream systems such as the Windows operating system, resulting in the need to write external interfaces for the same class library in different operating systems, doubling the workload

Third, the coupling of the operating system is strong. The existing solutions must use a large number of Windows system APIs in the Windows operating system. It is difficult to use pure C++ language to realize all functions, which is not conducive to the development of open source projects and cross-platform projects.
