Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of linking a plurality of programs written in a plurality of programming languages to generate one execution program. The present invention relates to a function name conversion device for converting a function name to enable the connection of.

[0002]

2. Description of the Related Art Conventionally, when a plurality of programs written in different programming languages are concatenated to create one execution program, a user generally assigns a function name in consideration of the specifications of a compiler of each programming language. Had to describe. This is because, when the programming language compiler converts the program into an object file, the function name is converted into the assembler language based on its own specifications. Therefore, when a user writes a program to be linked with a program compiled by a compiler of a different programming language, the function name converted by the compiler of the programming language in which the program is written is the programming language of the program to be linked. I had to write the function name so that it would match the function name converted by my compiler.

For this reason, some programming language compilers have the option of automatically converting function names so that they can be linked to the desired programming language. This has a function name conversion device inside the compiler and, when an option is specified, converts the function name in the program source code using the function name conversion device.

A conventional function name conversion device will be described below with reference to FIG. FIG. 8 is a block diagram of a conventional function name conversion device. In FIG. 8, 81 is a program source code for performing function name conversion, 82 is a function name linked to a different programming language in the program source code, and 83 is a function name extraction unit for extracting the linked function name 82 from the program source code 81. , 84 is a function name conversion unit for performing a function name conversion process, and 85 is a program source code including the function name converted by the function name conversion unit 84.

In the function name conversion device configured as described above, first, the function name extraction unit 83 makes the function name 8 to be linked.
Based on 2, the function name to be linked in the program source code 81 is extracted, the function name conversion unit 84 converts the function name, replaces the converted function name, and ends the process.

[0006]

However, in the above-mentioned conventional configuration, the function name conversion method is fixed and cannot be applied to many existing compilers of programming languages, and the compiler of the target programming language is also specific. Will be limited to. Therefore, when writing a program in a programming language that is not covered by the above programming languages, the user must have knowledge of the specifications of the compilers of the respective programming languages and knowledge for connecting different programming languages. I won't. Further, when converting the function name, even if the user converts the function name while describing it, there is a possibility that the conversion may be wrong and the connection may not be performed correctly.

The present invention solves the above-mentioned problems of the prior art. By inputting the name of a programming language compiler, the function name is automatically linked without the user being aware of the specifications of the compiler of each programming language. The purpose is to provide the function to convert to possible function names.

[0008]

In order to achieve this object, a function name conversion device of the present invention is designated as function name conversion information holding means for holding function name conversion information between a plurality of programming language compilers. Function name conversion information retrieving means for retrieving the function name conversion information holding means from the function name conversion information holding means based on the programming language compiler name, and extracting the specified function name from the program source code to obtain the function name conversion information. And a function name conversion means for converting the function name based on the search result of the search means.

[0009]

According to the present invention, the function name conversion information holding means for holding function name conversion information among a plurality of programming language compilers based on the programming language compiler name for which the function name conversion information retrieval means is designated has the function name from the function name conversion information holding means. Of the specified function name from the program source code by the function name conversion means, and the function name conversion means converts the function name based on the search result of the function name conversion information search means. It is possible to connect programs without paying attention to the specifications of the programming language compiler.
