Using the AMESim MATLAB/Simulink Interface7.2. Common problems and their solutionsCompilation failure with a Line too long error messageVersionsAll Matlab versions under Windows.Situation• When compiling an AMESim system containing interface blocks, the compilation failsand the following error message is displayed in the AMESim compilation window:'...Line too long...'.• Furthermore, the DLL file representing the S-Function is not generated. And whentrying to run the simulation in Simulink, an error message indicates that the S-Functiondoes not exist.Solution• Close the current AMESim session and login with Administrator privileges.• First check that the AME environment variable points to the AMESim installationdirectory.• Go to the %MATLAB%\bin\win32\mexopts directory (where %MATLAB% is theMatlab installation directory).Depending on the MS Visual C++ version you use, copy the following file and paste itinto the %AME%\lib directory (where %AME% is the AMESim installation directory):for Visual C++ 5, copy msvc50opts.bat,for Visual C++ 6, copy msvc60opts.bat andfor Visual.NET, copy msvc70opts.bat.• Go to the %AME%\lib directory.• Drag the msvc..opts.bat file and drop it onto the install_big_simulink_interface.exe file:one file is generated: mexopts.bat andone file is modified: simulink.make.• Logout and login with your user account.• Launch AMESim and re-compile the system.Compilation window is blocked during the first use of the interfaceVersionsAll Matlab versions under Windows.Situation• The AMESim/Simulink interface is used for the first time.• When compiling the AMESim system with Simulink blocks, the compilation windowin AMESim seems to be blocked and the following pieces of information are displayed:26

To avoid any problem, it is recommended that this is done always.One way to achieve this is to clear the AMESim mex function from (Matlab) memorybefore starting a new simulation. This can be done in three ways, manually or27
