Running C/C++ code analysis for a program

To run C/C++ code analysis for a program, run the Run C/C++ Code Analysis action on a makefile (.mak) in your TPF project.

Before you begin

Ensure that your TPF Toolkit is connected to Linux® on IBM Z®.
Optional: Configure C/C++ code analysis preference settings.
The Run C/C++ Code Analysis option creates local copies of include files that are included directly or indirectly by project source files. The local copies are removed from your local machine when the TPF project is deleted. You can configure the maximum size of any individual include path to be copied to the local machine on the C/C++ Code Analysis preference page.

About this task

Each time you add new C/C++ source files to the TPF project, if you want to get the refreshed analysis information, you need to run the Run C/C++ Code Analysis action on the current set of project files.

Procedure

In Project Explorer, right-click the makefile (.mak), and click Run C/C++ Code Analysis.

Results

Progress is shown in the Console view. Wait for a completion message. After completion, C/C++ files are automatically refreshed with the analysis information, which provides code highlighting, navigation, and content assistance, and resolves static analysis error and warning markers.
An Includes directory is created or updated in the TPF project. The directory lists all the include paths. All the successfully added include paths are also added on the Paths and Symbols properties page for the program. To view the page, right-click the program, and click Properties > C/C++ General > Paths and Symbols.
Note: The include paths are listed in the alphabetical order, which is different from the order that the include paths are used to resolve include files and associated symbols. The include paths are used in the order that is specified on the Paths and Symbols properties page.
If one or more included paths fail to be generated, the errors are displayed in the Problems view. To open the Problems view, click Window > Show View > Problems.

What to do next

Open your C/C++ source files in an editor.
You can customize markers in your C/C++ source files. For example, you can hide or show markers or change the severity of markers:
1. Click Window > Preferences > C/C++ > Code Analysis to open the Code Analysis preference page.
2. In the Name column, select or clear the check boxes to enable or disable markers.
3. In the Severity column, select Info, Warning, or Error for a marker.
4. Click Apply and Close.
As an alternative to the Run C/C++ Code Analysis option, you can manually specify include paths one by one:
1. Right-click a TPF project or a source file.
2. Click Properties > C/C++ General > Paths and Symbols.
For more information, see Adding Include paths and symbols in Managed Build System.
If markers persist in the editor after you fix all the errors and issues, you can disable the markers. For more information, see Disabling static analysis markers in C/C++ files.
