To use SystemModeler, a C/C++ compiler is needed. Normally SystemModeler will auto detect available compilers and select one; if a different compiler is desired or if the compiler is not auto detected, the compiler settings need to be changed.
To change the compiler settings, open the Options dialog box by choosing Tools ▶ Options. The compiler settings are available in the Compiler view. Select the desired compiler from the list of auto-detected compilers or select "custom" if the desired compiler is not auto detected. When configuring a custom compiler, specify the desired compiler type: MinGW, Microsoft Visual C++, G++, or Clang++. The supported compilers depend on your operating system; see the section on supported compilers. Additionally, the following need to be specified:
- For Microsoft Visual C++, specify version of Visual Studio as well as the location of vcvarsall.bat/VsDevCmd.bat and the arguments to the setup script.
- When using clang++ from Xcode without installing the command-line tools, it is also necessary to specify the path to the platform SDK. The platform SDKs are usually located in /Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs.
On Windows, SystemModeler may be able to download and install a compiler for you. To check online if there are any compilers available for assisted download and installation, click the Check for Compiler button.
On Mac, SystemModeler has been fully tested with Clang from Xcode version 6.2. It is likely that SystemModeler will work with any C++ compiler that is compatible with that version, i.e. any Clang from Xcode >= 6.2 from Apple Inc.
On Linux, SystemModeler has been fully tested with GCC/G++ 4.4 (32-bit and 64-bit). It is likely that SystemModeler will work with any C++ compiler that is compatible with that version, i.e. any GCC/G++ >= 4.4.
Wolfram SystemModeler provides functionality that makes it easy to interact with it from the Wolfram Language. When you start SystemModeler for the first time, it will automatically make this functionality available in Mathematica, if Mathematica is installed on the computer.
To configure the Wolfram Language functionality for a specific version of SystemModeler, it is possible to force a configuration. To do so, go to Tools ▶ Options in the SystemModeler menu. Then select Mathematica on the left side, under Global. Click Configure SystemModeler Link. For the configuration to succeed, Mathematica cannot be running, so be sure to close it when configuring.
By default, SystemModeler will use the system default UI-language, with a fallback to English if a translation does not exist for that language. To manually configure the UI-language and override the system settings, go to Tools ▶ Options and select General on the left side, under Global. Select the desired language from the Language list, press OK, and restart SystemModeler.
