아래의 절차는 기존 C 코드 베이스를 Eclipse 프로젝트로 불러오는 방법과 Linux 커널과 같은 대규모 C 프로젝트의 경우 필요한 고급 프로젝트 설정 방법을 자세히 설명한 것입니다.


Eclipse에서 C 프로젝트 불러오기

  1. 프로젝트가 Makefile이 있는 경우에 불러오기:
    • 패키지 익스플로러에서 마우스 오른쪽 클릭하십시오.
    • 불러오기를(Import)’ 선택하십시오.
    • 팝업 대화창에서 C/C++를 펼쳐 ‘기존 코드를 Makefile 프로젝트로(Existing Code as Makefile Project)’를 선택한 후 ‘다음을(Next)’ 클릭하십시오.
    • 프로젝트 이름을 입력한 후 불러올 디렉토리를 지정하십시오.
    • 완료를(Finish)’ 클릭하십시오.
  2. Import, if the project does NOT have a Makefile:
    • Right-click in the package explorer.
    • Select New > Project…
    • In the popup dialogue, select General > Project and click Next.
    • Enter a project name and click Finish.
    • Right-click on the project and select Import.
    • Enter the parent directory, select files to import, and click Finish.


Advanced Set up for C projects

For a typical C project, no further setup is necessary. However, large projects like the Linux kernel have a complicated build system that Atlas must understand in order to map the code correctly. To do this Atlas will analyze the build commands used to build the project. The steps below detail the changes necessary to map only the files built by the make file.

  1. Add the compiler build command:
    • Right-click on the project in the package explorer and select Properties.
    • Under Atlas C/C++ Build, add the name of the compiler used by the project to the Build Commands. Atlas will look for commands sent to these compilers when parsing the output of the project's makefile.
    • Click OK.
  2. Use information from build commands
    • Right-click on the project in the package explorer and select Properties.
    • Select Map only files in current build under Source files to map.
    • Select Use discovered configuration for files in the current build under File configuration.
    • Click OK.


Troubleshooting: If Atlas is unable to properly map the project, try the following fixes:

  1. Clean and build the project and make sure the build output is being correctly parsed:
    • Right-click on the project in the package explorer and select Properties.
    • Look under Atlas C/C++ Build > Build Configuration File.
    • If the Open button under Build Configuration File is grayed out, or if it says zero files were found, then Atlas was unable to detect the build configuration. Select C/C++ Build and uncheck “Use default build command”.
    • Adjust the command to make the output verbose. Necessary flags may vary; common options include “V=1” or “VERBOSE=1”.
    • Clean and build the project and check that Build Configuration File is nonzero.
  2. If Atlas’ code map is still empty, it may be that the Makefile is improperly reporting changing directories.
    • Right-click on the project in the package explorer and select Properties.
    • Select C/C++ Build and uncheck “Use default build command”.
    • Add the flag “--print-directory”.
    • Clean and build the project.


For versions of Atlas before Atlas 3.0, see the set up instructions at Configuring C Projects for Atlas 2.0.
