File compiling method and device

Abstract

The invention provides a file compiling method and device. The file compiling method includes the steps of on the basis of a dependence relation of a target file on a source file, a first header fileand a second header file involved in the first header file, compiling the source file, wherein the first header file is the header file involved in the source file; when a compiling error caused by the second header file is detected, preprocessing the first header file and obtaining a third header file involved in the first header file at present; according to the source file, the first header file and the third header file, updating the dependence relation; on the basis of the updated dependence relation, compiling the source file to regenerating a target file. According to the file compilingmethod and device, by updating the dependence relation of the target file on the source file and the header files, normal execution of a compiling process can be achieved under the condition that theheader files indirectly involved in the source file are modified, and the compiling efficiency can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a method and device for compiling files. Background technique [0002] In the process of software development, multiple source files often share the same data or functions. In order to make code writing concise, developers usually write the above data or functions in header files, and use them when they need to refer to the above data or functions. The header file can be included in the source file through a specific syntax. During the compilation process, usually a set of dependencies can also be established for the target files to be generated, and the dependencies describe which source files and header files are required to generate the above target files. Due to the existence of this dependency, if the header file or source file required to generate the above target file is modified later, it will trigger the recompilation of the source file to regenerate the abo...

AI Technical Summary

Problems solved by technology

The above modification will trigger recompilation of the source file containing the above header file 1 to generate the corresponding target file, but since the above modification will not cause changes in the original dependencies, when the header file indirectly included in the source file is modified , recompiling the source file may cause an error that the header file cannot be found, resulting in compilation failure
