As shown in Figure 2, embodiment of the present invention procedure script Compilation Method comprises the steps:
Step S11: information generated source code, in described information source code, will compile information definition is global variable;
Step S12: program source code is compiled together with program compilation information source code;
Step S13: read the global variable in the program after compiling, obtain compiling information.
Here, described compiling information at least comprises version number and the compilation time of compiled program.By checking the whether version of normal issue of version that the compiling information such as version number and compilation time can confirm current use, if version number does not mate with key word with compilation time or do not conform to normal information, version is not the version of normally issuing; When there is certain problem in program, also can be by checking that the compiling information such as version number and compilation time confirm whether occurred problem has been revised in redaction, if find that by checking version number and compilation time the version of current use is not latest edition, can search the latest edition of present procedure, thereby whether the problem that judgement occurs is revised in redaction.Compiling information can also comprise that other are for confirming the information of program version.
In step S11, described information generated source code, can be in the Makefile of program file, invoke script, pass through called script information generated source code, this program compilation information source code is global variable by the program compilation information definition of aforementioned program source code, such as compiled version number and compilation time etc., so that the calling of later stage.For example, when compiling information is version number and compilation time, can invoke script, to writing in described script, obtain the version number of program compiler and the code of compilation time.The code sample of the code of program compilation information source in a preferred embodiment of the invention, is as follows:
cat>version.c<<EOV
Char*__version=" version number "
Char*__time=" compilation time "
EOV； (1)
Wherein, _ _ version is version number's global variable of definition; _ _ time is the compilation time global variable of definition, the respectively compiled version of representation program source code number and compilation time, but the present invention is not restricted to this.Described version number the serve as reasons character string that letter forms, for example f5.0; The form of described compilation time can be the order `date '+%a%d-%b-%y%R ' ` under linux, and by this order, obtaining current time is compilation time, and the result for example getting can be: Tue 22-Apr-1414:16.So, the compiling such as version number and compilation time information is defined as global variable, thereby can by present procedure, within the scope of universe, be called and read, and without generating separately a file of preserving compiling information, also without carrying out independent file operation, read compiling information.
