Configuring Compiler Options

You can change the options that are used when compiling source files.
To view or change the compiler options, follow these steps:
  1. In the toolbar, click the Tools icon and then select Compiler Options from the drop-down menu.

  2. In the Compiler Options window, configure the options that should be used when compiling source files.
    Note: For more information about Mosel compiler options, see the Mosel Reference Manual.
    You can configure the following settings:
    BIM File Output Folder
    The folder within the project where intermediate BIM files are stored during compilation.
    Custom Python Path
    The full path to the Python environment to use for this project. If you do not specify a custom path, the system default Python environment is used.
    Tip: You can use a custom Python path, along with custom arguments, to select a Python runtime environment with the conda package. For more information, see Choosing a Python Environment Using Conda.
    Custom Python Arguments
    Any command-line arguments you want to pass to the Python interpreter (for example, to set optimization or debug levels). Keep in mind that Xpress Workbench will append additional arguments to the command string at run time.
    Debugging Information
    The information to include in the generated BIM file. Select one of the following options:
    • Remove private object names: The names of private variables, constraints, and subroutines are not saved to the BIM file.
    • Add debugging information: The -g command line flag is passed to the Mosel compiler. Use this option to locate a runtime error.
    • Add debugging and tracing information:

      The -G command line flag is passed to the Mosel compiler. This option is required to run the model with the debugger.

    By default, private declarations in Mosel are stripped on compilation. Declarations are private unless explicitly prefixed with the public keyword. Any entities in your Mosel code that need to be visible to Xpress Insight must be declared public.
    Implicit Declarations
    How to handle symbols that are not explicitly declared in a declarations block. Select one of the following options:
    • Allow implicit declarations:

      No command line flags are passed to the Mosel compiler. Implicit declarations are silently accepted.

    • Forbid implicit declarations:

      The -ni command line flag is passed to the Mosel compiler. Implicit declarations cause the compilation to fail with an error.

    • Warn about implicit declarations:

      The -wi command line flag is passed to the Mosel compiler. Implicit declarations are accepted, but the compiler prints a warning.

    Treat Warnings as Errors
    Whether to pass the -we command line flag to the Mosel compiler. Select this option if you want the compiler to treat warnings as errors, such that any warning causes the compilation to fail.
    Generate Doc Annotations
    Whether to pass the -D command line flag to the Mosel compiler. Select this option if you want to generate documentation annotations in the resulting BIM file. (By default, documentation annotations are ignored.)
    Enable Xbim Extension
    Whether to pass the -I command line flag to the Mosel compiler. Select this option if you want to enable the xbim extension, which causes additional symbol information (such as array index names) to be stored in the generated BIM file.
    Note: When you run a model from Xpress Workbench, the -g option is automatically added so that stack traces can be displayed if an error occurs. When you debug a model from Xpress Workbench, the -G option is automatically added.
