Simulink C2000 linux Error calling generated SFunction, trasf_sfun. Invalid MEX-file

Hi, everybody

i'm linux matlab user, i'm working on simulink with C2000's blocksets. When i run in normal mode, without connected board, it shows this message:

c28xdmclib/Ramp Generator/Convert Param To fix-pt with floor rounding mode/Embedded MATLAB Function

MATLAB Function Interface Error: Error calling generated SFunction, trasf_sfun. Invalid MEX-file

segment map object failed, operation denied

I've got code composer studio V5.

Why? please helpe me!!

During normal mode simulation, Simulink generates a MEX-file from Embedded MATLAB Function blocks for execution. The MEX-file typically has the name modelname_sfun, which is trasf_sfun in your case. You may read the documentation on Invalid MEX-File Error, to understand when this error occurs. My guess is that this model was previously from the same (network?) location from a different machine where the MEX-file was generated. At the time the file was generated, it created dependencies on certain run-time libraries (especially if Microsoft Visual Studio was configured as the MEX-compiler on that machine), which don't exist on your machine. You may try deleting the auto-generated MEX-file from the current directory, so that Simulink is forced to re-generate it, if you like.
