Method and equipment for compiling operating system

Abstract

The invention provides a method and equipment for compiling an operating system. The method comprises the following steps of: analyzing a source code data packet to be compiled into a compiling dependency table and a compiling product table; creating a compiling sequence table, and adding dependency items in the compiling dependency table into the compiling sequence table based on the compiling product table; sequentially compiling the plurality of packages in the compiling sequence table according to a sequence based on a compiling environment, and judging whether each time of compiling succeeds or not; and in response to successful compiling, compiling the next packet until compiling is completed. By using the scheme of the invention, the compiling time of the operating system can be greatly reduced, and the risk of compiling failure is reduced.

Description

technical field [0001] This field relates to the computer field, and more particularly relates to a method and device for compiling an operating system. Background technique [0002] The localization of the operating system is the fundamental guarantee for the localization of software, and it is a position that the software industry must conquer. The operating system plays an important role in connecting the past and the future in the localization of IT, undertaking the upper-level software ecology and the underlying hardware resources. Operating system products are facing a trade blockade, so self-reliance is imperative. At present, the compilation method of the operating system mainly relies on the open source minimal compilation system. The minimal compilation system builds its own minimal compilation environment, and then repeats the compilation in its own minimal compilation environment until the operating system is fully compiled. Finish. Then there are the followin...

Problems solved by technology

Then there are the following problems in the above compilation method: First, the compilation package update problem. There are about 2,000 SRPM packages in an operating system, and there are dependencies between various packages. If a certain The package is updated, and the operating system needs to be recompiled, which may take a long time; the second is that the compilation time is too long, because the compilation sequence cannot be determined, so the method of circular compilation is adopted, and the number of cycles cannot be determined, so the compilation time may exceed long

The third is compilation failures. There must be a lot of failures to build and compile without knowing the dependencies, and some compilation failures may be due to problems in the compilation environment. If the compilation order is not known, it is only after many build failures. It may be determined that it is a problem with the compilation environment, which is very time-consuming
