Compiler

C Compiler

Select the compiler version to compile the Modelica code before a virtual execution.

An unavailable compiler preference indicates that the compiler version is not installed on the computer.

Important: For detailed information about compilers, for example, what compiler versions are supported, see Program Directories, the Dymola Behavior Modeling app. A 3DPassport is required to display this page.

Visual Studio 2012 (11.0)

The default access path is used to locate this version.

Visual Studio 2015 (14.0)

The default access path is used to locate this version.

Visual Studio 2017 (15)

The default access path is used to locate this version.

Visual Studio 2019 (16)

The default access path is used to locate this version.

Customized Visual Studio Path

If the Visual Studio is not stored in the default path, select this preference and browse for the access path.

MinGW GCC Full Path

Select this option to use MinGW GCC. After selection, you must select 32/64-bit versions:

32-bit Select this option to use a 32-bit GCC compiler. If the MinGW executable is not stored in the default path, browse for the full access path. For example: C:\MinGW\bin\gcc.exe.
64-bit Select this option to use a 64-bit GCC compiler. If the MinGW executable is not stored in the default path, browse for the full access path. For example: C:\MinGW64\bin\gcc.exe.

Note: You might need both compilers, for example, if you want to export an FMU as both a 32-bit and a 64-bit executable.

By default, Visual Studio 2015 (14.0) is selected.

Linux cross-compilation (WSL)

You can activate Linux cross-compilation.

Enable WSL using: <path to wsl.exe>: Select this option to activate Linux cross-compilation. If the "Windows Subsystems for Linux" executable is not stored in the default path, browse for the full access path.

By default, This preference is cleared.

Custom Options

You can enter compiler and linker options. These options are for advanced users.

Verify Compiler Setup

Click Test Compiler to test the selected compiler. See Dymola Behavior Modeling User's Guide: Reference Information: Compilers for more information.

External C Function Compilation

When simulating a Modelica model using external C function compilation, you need to enter the path to the directories containing your files.

External C functions directory path(s): Type the paths separated by a semicolon (";").
Note: You can browse for the first path.
External libraries directory path(s): Type the paths separated by a semicolon (";").
Note: You can browse for the first path.

Note: External C function compilation can be done without using these preferences. See Dymola Behavior Modeling User's Guide: Managing Classes: Calling External C Functions in a Function for more information about the alternative.
