Method for simplifying source code based on Makefile source code simplifying device

Abstract

The invention discloses a method for simplifying a source code based on a Makefile source code simplifying device. The method comprises the steps: the source code simplifying device is connected with a far terminal Linux server through the Internet, and a network card in the source code simplifying device receives source codes from the server and transmits the source codes to a simplifying module to be simplified; the simplifying module simplifies the sound codes, the relationship between a kernel source code file and a catalogue and configuration options is extracted from Makefile of a Linux kernel, and then through scanning .config files, kernel configuration options are obtained; then, source code files and the catalogue which are not checked and correspond to the configuration options are all deleted and displayed to a user; the user can examine the codes, or modify the codes, or note the codes, look for the codes and add bookmarks to the codes; the codes which are updated are uploaded to the server through the Internet. The method is implemented through the scheme, so that the number of kernel sound codes can be substantially reduced, and the difficulty of analysing and positioning by developers is reduced.

Description

technical field [0001] The invention relates to the field of simplification and decoding of Linux servers, in particular to a method for simplification of source code by a Makefile-based source code simplifier. Background technique [0002] The Linux kernel customization on embedded devices, especially the modification at the source code level, often faces such a problem: the Linux source code is very large, and developers must analyze it with the help of tools, but there are often problems that have nothing to do with customization. Some source codes significantly slow down the analysis speed. For example: in the root directory of the source code, the developer wants to use a text search tool to locate the usage of a variable, but the result shows a series of results under drivers that the developer does not need to consider at all (because many non-embedded device drivers will also use this variable). This undoubtedly greatly reduces the development efficiency. [0003]...

Problems solved by technology

[0002] The Linux kernel customization on embedded devices, especially the modification at the source code level, often faces such a problem: the Linux source code is very large, and developers must analyze it with the help of tools, but there are often problems that have nothing to do with customization. Some source codes, greatly slowing down the analysis speed

[0007] For the above two solutions, no matter which one is, there is no way to remove unnecessary irrelevant redundant code in the Linux kernel source code, so there will be such a problem: for a kernel function or variable, in the process of a search In many cases, code analysts must manually remove those search results that they do not need, which is extremely time-consuming

[0008] In addition, existing Linux analysis tools can only run on desktops or laptops, and users cannot read and modify the code anytime and anywhere, and cannot see the modified results at the same time
