There is provided a method for processing a source file to generate an object file, comprising: obtaining a header file referenced by the source file; in response to the source file calling a data symbol defined in the header file, creating an indicator of a definition the data symbol, wherein definitions of different data symbols correspond to different indicators; and adding the indicator into a compiling result of compiling the source file so as to generate the object file. With the present invention, a dependency between the source file and the header file can be recorded, and the number of source files needed to be re-compiled can be reduced on the basis of the dependency.

Processing source file

A method and system for structuring program code to implement program debugging of the program code using tracking of variables. A first variable to be tracked and a first expression associated with the first variable are determined. The program code includes the first variable and the first expression. A reverse scanning of the program code is performed to search for a first assignment expression within a first assignment statement that assigns a value of the first assignment expression to the first variable. In response to finding the first assignment expression via the reverse scanning, a first watch point for determining a true/false value of the first expression is inserted into the program code after the first assignment statement.
