Known Issue

When exporting the EASY5 model for MATLAB, I get an error and the compilation fails.
This is what appears in the xi_demo.xmi_build.log file:
CL /c /MD /O2 ez_env_set.c
Traceback (most recent call last):
  File "C:\MSC.Software\Easy5\2013\easy5x\bin\", line 2423, in <module>

    status = call(tempArgs, stderr=STDOUT)

The cause is that EASY5 cannot find the C compiler. This could be because there is no C compiler installed on the machine, or the path to the C compiler is not in the Windows Path. The S-Function interface to MATLAB that EASY5 uses is compiled using a C compiler. Therefore, an installed C compiler is a requirement in order to use this method.
The newer FMI interface does not require a C compiler. So if obtaining a C compiler is an issue, you can use the FMI interface instead of the classical s-Function interface via the XMI library.
Install a compatible C compiler and make sure that the path to it is in your Windows PATH within the EASY5 environment.
For a list of compatible C compilers on Windows 64-bit, see this KB article:
Otherwise switch to the FMI method instead.
Be aware that if you decide to go the FMI route, you'll need to use EASY5 2015 or later, as only those versions support FMI.
