The project configurer uses the Clang module to generate a Lattix project from C/C++ source code. You do this by specifying the source file(s) and directory structure. Since analysis of C/C++ files is highly dependent on the complication options and the correct specification of include paths, this approach requires considerable care.

Using the Project Configurer

The project configurer allows you to create units. Each unit corresponds to a link entity in your application such as an executable, a static library or a dynamic library. You can duplicate files and directories across units. If you do not specify a unit, all the source files and directories will be treated as part of a single unit.

The project configurer also allows you to specify the compile options for each file within each unit. If you specify an option on a unit or a directory, that option is applied to all the source files within the subtree of the unit or directory.

Here are examples of some useful options in the project configurer:

  • -DOS=WIN32   set the value of the OS macro to WIN32
  • -I/MyProject/MyIncludes  adds directory /MyProject/MyIncludes to the include path

In addition to specifying the options in the Project Configurer, there are additional options that you can specify on the Options tab in the Create New Project dialog:

  1. Include standard Clang headers: Include this if you want to use the standard Clang headers. It is generally a good idea to enable this option if you haven’t specified the headers that are used by your compiler
  2. Automatically detect include directories in source tree: Use this to force the generation of the include path based on the header files in your source tree. This is useful if the header files are present in the source tree but the include paths aren’t set up correctly. Please note that this option is now enabled by default in version 10.1.2+.
  3. Include Directories: You can specify any additional include directories for the entire project.
  4. Compiler Options: You can specify any additional compilation options for the entire project.

Check for Errors

Check for errors by bringing up the Clang Reports using Reports->Clang Reports…->Diagnostics by File. Please pay particular attention to missing include file errors. Most other errors will typically not have any significant effect on the analysis. Fix the errors and re-create (or update) the project.

Hint: To minimize the time, remember that you can test by specifying just a single source file. The Options tab on the Create New Project dialog has an option called Include files matching these names. Simply enter the full path name of the file and then only that file will be compiled.


You are now ready for further analysis using Lattix Architect. If you have not created a Dependency Structure Matrix view, you can create that now. Here are a couple of videos that can help:
