System and Method for Compiling a Web Based Operating System

The present invention relates to a system and method for compiling a web based operating system, and more particularly, to a system and method for compiling a web based operating system for compiling and configuring an operating system for various hardware on the web.

The configuration of a program development package that can compile an embedded operating system that is currently widely used is configured in a user's local personal computer (PC) 10, as shown in FIG. Environment 11, cross compiler 12, binary utility 13, Kernel Component Object 14, and user library and header 15 are included.

The IDE 11 is a tool for allowing a user to conveniently compile, and is generally a graphical user interface, and most of the application programs for Windows are operated on the local PC 10. In addition, the IDE 11 compiles and links the kernel component object 14 and the user library 15 using the cross compiler 12 and the binary utility 13. It also means the whole development package.

The cross compiler 12 is a compiler that generates machine code that can be driven in a desired central processing unit (CPU).

The binary utility 13 is a tool for assembling, linking, and activating objects compiled by the cross compiler 12. The binary utility 13 generates a linker, an active component, and the like. Tools for dealing with binary objects.

The kernel component object 14 is a component having various functions embedded in a kernel provided in a compiled form. The kernel component object 14 links kernel components set by a user to form a kernel required by a user. Here, the kernel may refer to a portion of an operating system or an entire operating system that is loaded from the system startup and always exists.

The user library and header 15 refer to libraries and headers for writing a user application.

When using the program development package configured as described above, the following operation is performed.

First, after installing the IDE (11) purchased from the developer or developer of the embedded operating system on the user's local PC (10), the user sets the kernel to suit the target board (Target) developed.

Therefore, the cross compiler 12 compiles. At this time, it compiles some kernel components (ie, some devices, drivers, etc.) that expose the source to the user, and decides to use the user. The kernel is created by linking the specified kernel components. At this time, the compiled object 14 is simply stored in the storage device on the user's local PC (10).

After that, the generated kernel is installed on the developed target board.

In addition, there are two major cases in which the defect of the operating system is found and corrected or upgraded by adding a function, that is, a reinstallation with a new version and an upgrade when there is an automatic patching tool. .

In case of re-installing with the new version, the developer must create a new package and send it to all the users who requested the new version, and the user must remove the existing version and install the new version.

In the case of upgrading the automatic patching tool, the developer must create a new package and save it on the server with the automatic patching tool, and the user must upgrade to the new version using the automatic patching tool.

As described above, since a technology for compiling a conventional operating system needs to install a program development package separately on a user's local PC, the user can use only the operating system in which the program development package can be run and how to use the program development package. You have to learn it separately, and you have to use a lot of CPU resources and disk space of your local PC.

In addition, the technology of compiling a conventional operating system is difficult to manage the version by developing and using a program development package by developers in the case of jointly developing the operating system, especially when developing a large system using a large number of boards There was also a disadvantage of having to manage the kernel binaries used separately.

In addition, the technique of compiling a conventional operating system requires that the developer stores the development environment and the operating system separately in different storage media and distributes them to users, and the user installs a separate complex development environment or has expertise. Since the operating system must be installed on the PC, it is difficult to apply new features or bug fixes of the operating system, it is difficult to apply quickly, and it is difficult to restrict illegal distribution of the program development package.

SUMMARY OF THE INVENTION In order to solve the above problems, the present invention provides a web-based operating system compilation system and method for compiling by setting the operating system for a variety of hardware on the web, an object thereof.

In addition, the present invention does not need to install a program development package separately on a user PC by setting up and compiling the operating system for various hardware on the web, so that the user can access the web browser on any operating system and compile the kernel. There is no need to learn how to install and use the program development package separately, and to save CPU resources and disk space of the user PC.

In addition, the present invention is automatically compiled by setting the operating system for a variety of hardware on the Web, even when the operating system is jointly developed, version management is made automatically, especially large system development using a large number of boards The goal is to make it easier to manage the kernel binaries used on each board.

In addition, the present invention is automatically compiled by setting the operating system for a variety of hardware on the web, even if the version is changed due to the addition of features and bug fixes of the operating system, developers can easily distribute and version management, the user is the latest version It's an easy and fast way to upgrade your operating system.

In addition, the present invention is to limit the illegal distribution of the program development package by allowing only the user who can access on the web to log in and use the limited control of each user, the purpose is to facilitate.

Web-based operating system compilation system according to an embodiment of the present invention for achieving the above object includes a user interface portion for performing an interface with the user over the Internet; A database management portion for storing and managing objects compiled by the user interface portion and compilation information in a database; A tool set portion for performing compilation through the user interface portion, assembling, linking, and activating the compiled objects, and performing user account and access management, configuration information management, and management of the database management portion; In the case of modifying the kernel by the kernel developer and upgrading the version, the version management part is directly included in the database management part.

Preferably, the user interface portion performs a user approval operation, downloads the compiled objects in the database management portion to the user, and selects an operating system version and hardware to execute a kernel configuration operation; A configuration CGI that provides kernel configuration to the user by the list CGI, provides help for each configuration, and executes a kernel compilation operation; The configuration CGI executes a compilation of the kernel by using the tool set part based on the information on the kernel configuration, displays the operation of performing the compilation, and displays the compiled objects and the compilation. And a compiled CGI for storing information in the database management part.

Meanwhile, in the web-based operating system compilation method according to an embodiment of the present invention, after checking a user's login through the Internet and performing a user approval operation, the compiled kernel information in the database, the kernel version to be compiled, and a screen for selecting hardware Displaying the process; Detecting a user's kernel version and a hardware selection and displaying the kernel configuration information items set in the database; And compiling the kernel based on user setting information according to the user's compilation request, and storing the compiled objects and the compiled information in the database. Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

In the web-based operating system compilation system according to an exemplary embodiment of the present invention, as shown in FIG. 2, all development environments are configured in the remote server 20. The user interface portion 21 and the tool set portion 22 are illustrated in FIG. And a version management portion 23 and a database management portion 24, the user logs in to the server 20 via the Internet 30 via a web browser at a remote location using a user terminal. It is made to use.

The user interface portion 21 interfaces with the user via the Internet 30 and comprises three CGIs, such as a list CGI 211, a configuration CGI 212, and a compiled CGI 213. .

The list CGI 211 performs a user approval operation, allows a user to download the compiled objects stored in the database management part 24, and selects an operating system version and hardware to configure the kernel. It performs the role of executing the configuration CGI 212 for.

The configuration CGI 212 allows the user to configure the kernel by executing the list CGI 211, provides help for each setting, and executes the compilation CGI 213 to compile the actual kernel. It plays a role. In this case, there are two types of kernel configuration, a part for configuring logical kernel information and a part for configuring hardware dependent parts.

The compiling CGI 213 is a cross compiler 221 in the tool set part 22 based on the setting information set by the user in the configuration CGI 212 by executing the configuration CGI 212. By using the binary utility 222, etc. in the tool set portion 22 to perform a compilation for the kernel, to display the operation to perform the compilation, the compiled objects and the compilation information Is stored in a database in the database management portion 24.

The tool set portion 22 is a cross-compiler 221 for compiling to generate machine code that can be driven on the target CPU, and to assemble, link and activate objects compiled by the cross-compiler 221. Includes a binary utility 222 and a server management tool 223 for managing the server 20.

The server management tool 223 performs a role such as user account and access management, configuration information management, and database management part 24 management, and is a tool that only an administrator can use.

The version management part 23 serves to directly reflect when a kernel developer modifies the kernel and upgrades the version. For example, the version management tool 231 such as CVS, Clearcase, and the kernel are included. It comprises a source 232. The kernel source 232 may be on the same server 20 or on another server (not shown in the figures for convenience of description).

The database management portion 24 includes objects compiled by the compiled CGI 213 in the user interface portion 21 (ie, kernel, configuration information, memory map, disassemble code, etc.) and compilation information. Manage the database that stores the.

A method of compiling a web-based operating system according to an embodiment of the present invention will be described with reference to the flowchart of FIG. 3.

The operations performed when the user compiles the kernel can be divided into the client side and the server side.

First, when the user side logs in by accessing the server 20 via the Internet 30 via a web browser at a remote location using the user terminal (step S1), the user interface portion 21 in the server 20 corresponds to the corresponding user. The interface with the user terminal is performed through the Internet 30.

That is, the list CGI 211 in the user interface portion 21 confirms the user's login to perform a user approval operation (step S2), and is compiled in the database management portion 24 in the server 20. In order to allow the user to download the created objects, first, a screen for selecting kernel information compiled from a database in the database management part 24 and a version and hardware of a kernel to be compiled is displayed (step S3).

Therefore, when the user selects the kernel version (ie, the operating system version) and hardware through the web browser (step S4), the list CGI 211 detects the selection of the corresponding kernel version and the hardware and configures the user for the kernel configuration. The configuration CGI 212 in the interface portion 21 is executed.

Accordingly, the configuration CGI 212 allows the user to configure the kernel by executing the list CGI 211 and provide a tool set portion 22 by the administrator in order to provide help for each setting. And display the kernel setting information items set using the server management tool 223 in step S5).

Then, when the user modifies the kernel configuration information through a web browser and executes compilation (step S6), the configuration CGI 212 detects a corresponding compilation execution command and compiles the actual kernel. Compiling CGI 213 in (21) is executed.

Accordingly, in the compiled CGI 213, a cross compiler in the tool set portion 22 based on setting information set by the user in the configuration CGI 212 by executing the configuration CGI 212. 221 is used to compile the kernel using binary utilities 222 and the like in the tool set portion 22, that is, the source managed by the server management tool 223 is stored in the tool set portion 22. ), And at the same time, display the operation to perform the compilation (step S7).

The compiled CGI 213 then stores the compiled objects (i.e. kernel, configuration information, memory map, disassembly code, etc.) and compilation information in a database in the database management portion 24. Step S8).

Here, the memory map is a map that defines the address of variables and functions of the program code, and the disassembly code refers to the code in which the program is generated at the assembly level.

Meanwhile, the version control part 23 in the server 20 includes, for example, a version management tool 231 such as CVS and a clear case, and a kernel source 232 to allow a kernel developer to modify the kernel and upgrade the version. In this case, it directly reflects the database management part 24.

As described above, by allowing the operating system to be compiled and configured on the web according to the present invention, there is no need to install a program development package on the user's PC separately, so that the user can use the web browser on any operating system. You can compile the kernel by connecting to, and you don't have to learn how to install and use the program development package, and you can save CPU resources and disk space on your PC.

In addition, even when jointly developing an operating system according to the present invention, version management is automatically performed, and in particular, it is easy to manage kernel binaries used for each board when developing a large system using multiple boards. Even if the version is changed due to the system's feature additions and bug fixes, it is easy for developers to distribute and version, and users can upgrade to the latest version of the operating system quickly and easily.

In addition, according to the present invention, by only allowing a user who can access the web to log in and use a limited number of users, the use of illegal program development packages can be reduced.
