Description

Technical Field

[0001] The present application relates to the field of computer technology, and in particular to a data processing method, device, equipment and medium for cross-compilation. Background Art

[0002] With the rapid development of the computer industry, various hardware platforms have appeared on computers. Due to limited hardware resources, some hardware platforms cannot compile programs directly, so cross-compilation is required on other platforms.

[0003] Cross-compilation is to compile an executable file or library on one source platform that can run on another source platform. During the cross-compilation process, you need to find the corresponding dependent header file. If the name of the dependent header file and the header file found by the command line are different in capital letters, the compilation will report an error, indicating that the corresponding header file cannot be found. For example, when compiling a library for the Windows environment in a Linux environment, because file names in Linux are case-sensitive, but file names in Windows are not case-sensitive, the above compilation error may occur during the compilation process.

[0004] Therefore, the case compatibility issue that arises during cross-platform cross-compilation is an issue that needs to be solved urgently. Summary of the invention

[0005] The embodiments of the present application provide a data processing method, apparatus, device and medium for cross-compilation, so as to solve the case incompatibility problem existing in the current cross-compilation process and improve the success rate of cross-compilation.

[0006] An embodiment of the present application provides a data processing method for cross-compilation, including:

[0007] Obtaining a configuration file, where the configuration file is constructed in the first platform based on the configuration of the second platform;

[0008] For each header file in the configuration file that the source file to be compiled depends on, the following operations are performed to obtain an updated configuration file: the absolute path of the header file is determined; if the header file is not found in the absolute path, the case of the characters in the header file name is ignored and the search is performed again; when the target file is found, the file name of the target file is used to replace the file name of the header file in the configuration file.

[0009] In an embodiment of the present application, during the cross-compilation process, after obtaining the configuration file, for each header file in the configuration file that the source file to be compiled depends on, first determine the absolute path of the header file, and then search for the header file based on the absolute path of the header file. If the header file is not found in the absolute path, it is determined that there is a case incompatibility problem in this header file. At this time, ignore the case format of the characters in the header file name and search again. When the target file is searched, use the file name of the target file to replace the file name of the header file in the configuration file to obtain an updated configuration file.

[0010] By replacing the file name of the header file in the configuration file with the file name of the target file, all header file names with case incompatibility problems in the configuration file are replaced. Compared with the existing technology, this can solve the case incompatibility problem in the cross-compilation process, avoid the case incompatibility of header files caused by platform differences in the cross-compilation process, and improve the success rate of cross-compilation.

[0070] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0071] The embodiments of the present application provide a data processing method, apparatus, device and medium for cross-compilation, so as to solve the case incompatibility problem existing in the current cross-compilation process and improve the success rate of cross-compilation.

[0072] Among them, the method and the device, equipment, and medium are based on the same application concept.

[0074] The following examples and embodiments are to be understood as illustrative examples only.

[0075] The following is a detailed description of each embodiment of the present application in conjunction with the accompanying drawings. It should be noted that the display order of the embodiments of the present application only represents the order of the embodiments, and does not represent the advantages and disadvantages of the technical solutions provided by the embodiments.

[0076] With the rapid development of the computer industry, various hardware platforms have appeared on computers. Due to limited hardware resources, some hardware platforms cannot compile programs directly, so cross-compilation is required on other platforms.

[0077] Cross-compilation is to compile an executable file or library on one source platform that can run on another source platform. During the cross-compilation process, you need to find the corresponding dependent header file. If the name of the dependent header file and the header file found by the command line are different in capital letters, the compilation will report an error, indicating that the corresponding header file cannot be found. For example, when compiling a library for the Windows environment in a Linux environment, because file names in Linux are case-sensitive, but file names in Windows are not case-sensitive, the above compilation error may occur during the compilation process.

[0078] Therefore, the case compatibility issue that arises during cross-platform cross-compilation is an issue that needs to be solved urgently.

[0079] In an embodiment of the present application, during the cross-compilation process, after obtaining the configuration file, for each header file in the configuration file that the source file to be compiled depends on, first determine the absolute path of the header file, and then search for the header file based on the absolute path of the header file. If the header file is not found in the absolute path, it is determined that there is a case incompatibility problem in this header file. At this time, ignore the case format of the characters in the header file name and search again. When the target file is searched, use the file name of the target file to replace the file name of the header file in the configuration file to obtain an updated configuration file.

[0080] By replacing the file name of the header file in the configuration file with the file name of the target file, all header file names with case incompatibility problems in the configuration file are replaced. Compared with the existing technology, this can solve the case incompatibility problem in the cross-compilation process, avoid the case incompatibility of header files caused by platform differences in the cross-compilation process, and improve the success rate of cross-compilation.

[0081] Before formally introducing the embodiments of the present application, it should be noted that the data processing method for cross-compilation provided in the embodiments of the present application can be executed by a terminal device that performs cross-compilation, and the embodiments of the present application do not limit this.

[0082] clang and gcc are two commonly used compilation tools, and both support cross-compilation. In the following description of the embodiments of the present application, only clang is used as an example. Of course, the data processing method provided in the embodiments of the present application is also applicable to cross-compilation tools such as gcc.

[0083] See also Figure 1 The implementation process of the data processing method for cross-compilation provided in the embodiment of the present application includes the following steps S101-S102:

[0084] S101, obtaining a configuration file, where the configuration file is constructed in the first platform based on the configuration of the second platform.

[0085] In the specific implementation, in the first platform, the project file to be compiled is obtained, and then the preset command is used to process the project file to be compiled, a project file directory is constructed based on the configuration of the second platform, and the configuration file is searched from the project file directory. Among them, the project file to be compiled can be written or uploaded by the user, and the embodiment of the present application does not limit this. The preset command can be a cmake command.

[0086] In actual applications, after creating the project file directory, the header file that the source file to be compiled (.cpp or .c) depends on has been set in the configuration file. The configuration file is generally depend.make or DependInfo.cmake. The file name is fixed, so you only need to find the files with these two file names to get the configuration file, and then you can get the header file that the corresponding .cpp depends on.

[0087] Since the file name of the configuration file is fixed, when searching for the configuration file in the project file directory, you can first search for a file with the first preset name in the project file directory. If a file with the first preset name is found and the file content is not empty, the file with the first preset name is determined as the configuration file; if a file with the first preset name is found and the file content is empty, search for a file with the second preset name in the project file directory, and determine the searched file with the second preset name as the configuration file. The first preset name is depend.make, and the second preset name is DependInfo.cmake.

[0088] In an example, the content of the depend.make file is in the format of Figure 2 As shown in the depend.make file, the *.h part after the colon is the header file that .cpp or .c depends on. Figure 2 The .. / include_path / example_inc1.h shown in the figure is a header file that .cpp or .c depends on. The * represents any character.

[0089] In another example, the content format of the DependInfo.cmake file is as follows Figure 3 As shown in the DependInfo.cmake file, *.cpp.obj.d is a file name, and the header file information that the .cpp depends on is in *.cpp.obj.d.

[0090] S102, for each header file that the source file to be compiled in the configuration file depends on, perform the following operations to obtain an updated configuration file: determine the absolute path of the header file, if the header file is not found in the absolute path, ignore the case format of the characters in the header file name and search again, when the target file is found, use the file name of the target file to replace the file name of the header file in the configuration file.

[0091] It should be noted that since the configuration files are divided into depend.make file and DependInfo.cmake file, the contents of the two files are different. Therefore, the specific implementation process of determining the absolute path of the header file and replacing the file name of part or all of the header files is explained below in combination with the two configuration files.

[0092] 1. The configuration file is depend.make file.

[0093] In this case, when determining the absolute path of the header file, the configuration file is parsed, the information of each header file is separated from the configuration file, and then the absolute path of each header file is determined based on the absolute path of the configuration file obtained in advance and the information of each header file. Specifically, from the address information of each header file, the relative path of each header file relative to the folder where the configuration file is located is obtained, and the absolute path and relative path of the configuration file are concatenated to obtain the absolute path of the header file.

[0094] Specifically, the depend.make file is usually separated by empty lines, indicating a .cpp or .c header file that is dependent on, such as Figure 4 As shown in the figure, for example, the source file cpp_file2.c to be compiled depends on three header files, whose names are example_inc4.h, example_inc5.h, and example_inc6.h. The .. / include_path2 / dirname23 in front of example_inc6.h indicates the relative path to the project file directory. The target product of the compilation is cpp_file2.co. The target products and dependent header file information of other source files cpp_file1.c and cpp_file3.c to be compiled are before and after the blank line.

[0095] In the specific implementation, read the depend.make content and save it in the variable cpp_depend_h_total, split it with empty lines, parse out the information corresponding to each source file to be compiled, and store it in the list variable cpp_depend_h_str_list, traverse each member of cpp_depend_h_str_list in turn, the member variable is cpp_depend_h_per_str, and then split the cpp_depend_h_per_str by newline characters to get the dependent header file information, and store it in the list variable cpp_depend_h_per_list. The format of the cpp_depend_h_per_list member is as follows: Figure 5 shown.

[0096] Then traverse the cpp_depend_h_per_list elements one by one, parse the .o file string and .h file string through the colon, and store them in the variables var_o_str and var_h_str respectively, for example Figure 5 The string in the example can be parsed as follows:

[0097] var_o_str=complier_result_path / cpp_file2.co

[0098] var_h_str=.. / include_path2 / dirname23 / example_inc6.h

[0099] The original file name of the header file is stored in the variable var_h_old, where var_h_old = example_inc6.h. By concatenating the absolute path of the depend.make file obtained in advance and the relative path of the .h file (the var_h_str variable mentioned above), the absolute path of the header file var_h_abspath can be obtained.

[0100] After obtaining the absolute path of the header file, use the preset function to search for the header file based on the absolute path of the header file. For example, through the function os.path.exist (var_h_abspath), determine whether the header file exists in the absolute path of the header file. If it exists, it means that the file name of this header file is not case-incompatible, and no replacement operation is required. Continue to process the next header file. If the header file does not exist in the absolute path of the header file, it means that the file name of this header file is case-incompatible. At this time, ignore the character case format of the file name and continue to search. When the target file is searched, the file name of the target file is stored in the variable var_h_new, and then the original file name and the correct file name of the header file whose file name does not match the case can be stored in the dictionary var_h_dict, var_h_dict={var_h_old:var_h_new}, until a cpp_depend_h_per_str is traversed.

[0101] Replace the specified substring in the string variable cpp_depend_h_per_str. The specified substring is var_h_old, which is replaced with var_h_new. After the replacement is completed, it is stored in the list variable cpp_depend_h_str_new_list. After traversing all cpp_depend_h_str_list, the latest cpp_depend_h_str_new_list is obtained. The cpp_depend_h_str_new_list is concatenated with blank lines to obtain the string variable cpp_depend_h_total_new. Then the depend.make file content is cleared, and cpp_depend_h_total_new is written into the depend.make file. This means that the file name of each header file whose file name does not match the case is replaced, which solves the case incompatibility problem in the cross-compilation process, avoids the case incompatibility of header files caused by platform differences during the cross-compilation process, and improves the success rate of cross-compilation.

[0102] Combine the following Figure 6 , the implementation process of replacing the file name of the header file whose file name does not match the case when the configuration file is the depend.make file in the embodiment of the present application is described in detail, such as Figure 6 As shown, the specific replacement process includes:

[0103] Step 601, read the contents of the depend.make file, save it in the variable cpp_depend_h_total, split it with empty lines, split cpp_depend_h_total, and store the resulting blocks in the list variable cpp_depend_h_str_list.

[0104] Step 602, parse each member cpp_depend_h_per_str of cpp_depend_h_str_list by line break, and store the parsing result in the list variable cpp_depend_h_per_list.

[0105] Step 603: for each cpp_depend_h_per_list, parse the .o file string and the .h file string through the colon, and store them in variables var_o_str and var_h_str respectively.

[0106] Step 604, the absolute path var_h_abspath of the header file is obtained by concatenating the absolute path of the depend.make file obtained in advance and the relative path of the header file recorded in var_h_str.

[0107] Step 605, determine whether there is a header file in var_h_abspath, if so, continue to execute step 603 to process the next cpp_depend_h_per_list, if not, execute step 606.

[0108] Step 606, continue searching by ignoring the case format of characters in the file name of the header file, and store the searched file name of the target file and the original file name of the header file in the var_h_dict dictionary.

[0109] Step 607, determine whether the header files in cpp_depend_h_per_list have been processed. If not, continue to execute step 603 to process the next header file. If it has been processed, execute step 608.

[0110] Step 608, after traversing one cpp_depend_h_per_list, use the dictionary var_h_dict to replace the file names of the header files whose file names in cpp_depend_h_per_str do not match the case, and then execute step 602 to process the next cpp_depend_h_str_list.

[0111] It should be noted that after all cpp_depend_h_str_list processing is completed, the updated depend.make file, that is, the updated configuration file, can be obtained.

[0112] 2. The configuration file is DependInfo.cmake file.

[0113] In this case, when determining the absolute path of the header file, first parse the configuration file, and parse the relative path of the dependent file from the configuration file. The dependent file contains the header file information that the source file to be compiled depends on; then, based on the absolute path of the configuration file obtained in advance and the relative path of the dependent file, determine the absolute path of the dependent file; finally, based on the absolute path of the dependent file, obtain the dependent file, and obtain the absolute path of each header file from the header file information contained in the dependent file.

[0114] Specifically, get the contents of the DependInfo.cmake file, such as Figure 7 As shown, the content after set(CMAKE_DEPENDS_DEPENDENCY_FILES is obtained by parsing and stored in the string variable dependInfo_str.

[0115] Then the string variable dependInfo_str is split by line breaks and spaces are removed to parse the list variable cpp_depend_list. cpp_depend_list stores the dependency information of all .cpp or .c in the configuration file. The element format of cpp_depend_list is as follows: Figure 8 shown.

[0116] Traverse each member (cpp_depend_per_str) in cpp_depend_list, and obtain the relative path of *.obj.d (i.e., the dependent file mentioned in the embodiment of the present application) by parsing cpp_depend_per_str through spaces. The absolute path of the DependInfo.cmake file obtained in advance can be used to determine the absolute path per_obj_d_abspath of *.obj.d.

[0117] Then, read the per_obj_d_abspath file and get the file content, such as Fig. 9As shown, the file content exists in the string variable per_obj_d_info. The string variable per_obj_d_info is split by newline characters and backslashes (\). All elements exist in the list variable cpp_depend_inc_list. cpp_depend_inc_list contains two elements, *.cpp and *.cpp.obj.

[0118] Traverse each element cpp_depend_inc_str of cpp_depend_inc_list, cpp_depend_inc_str is the absolute path of the *.h header file, the original file name of the *.h header file is represented by the variable var_h_old, and *.cpp and *.cpp.obj are skipped without processing. When traversing to .h, the function os.path.exist (cpp_depend_inc_str) is used to determine whether the header file exists. If it exists, it indicates that the file name of this header file does not exist. For the problem of lowercase incompatibility, no replacement operation is required, and the next header file can be processed. If the header file does not exist under the absolute path of the header file, it indicates that the file name of this header file is case incompatible. At this time, the character case format of the file name is ignored and the search is continued. When the target file is found, the file name of the target file is stored in the variable var_h_new, and then the original file name and the correct file name of the header file with case mismatch can be stored in the dictionary var_h_dict, var_h_dict={var_h_old:var_h_new}.

[0119] Finally, replace all substrings of var_h_old in the dictionary variable var_h_dict with the corresponding var_h_new, that is, replace the file names of header files whose file names do not match the case in per_obj_d_info, until the entire cpp_depend_list is traversed, thus achieving the replacement of the file names of each header file whose file names do not match the case, solving the case incompatibility problem in the cross-compilation process, avoiding the case incompatibility of header files caused by platform differences in the cross-compilation process, and improving the success rate of cross-compilation.

[0120] Combine the following Fig.10 , the implementation process of replacing the file name of the header file whose file name does not match the case when the configuration file is the DependInfo.cmake file in the embodiment of the present application is described in detail, such as Fig.10 As shown, the specific replacement process includes:

[0121] Step 1001, obtain the content of the DependInfo.cmake file, extract the key string, and save it in the variable dependInfo_str.

[0122] Step 1002, parse the string variable dependInfo_str through the line break, and save the parsing result in the list variable cpp_depend_list.

[0123] Step 1003, traverse each member cpp_depend_per_str in cpp_depend_list, parse cpp_depend_per_str to obtain the absolute path per_obj_d_abspath of *.obj.d.

[0124] Step 1004, read the per_obj_d_abspath file, obtain the file content, and store the file content in the string variable per_obj_d_info.
