At first I got several problems with the different types and sizes of my variables due to the restrictions of the embedded environment in order to be complient with C.However when everything seemed solved and I tryed to run the simulation from Simulink I stopped having problems with variables but instead started to get this error:Embedded MATLAB Interface Error: Error calling generated SFunction, SimulationGPS_sfun. Invalid MEX-file 'C:\Users\trrmsm\Documents\Karyon\Simulink_GPS\SimulationGPS_sfun.mexw32': C:\Users\trrmsm\Documents\Karyon\Simulink_GPS\SimulationGPS_sfun.mexw32 is not a valid Win32 application.I've been searching in the forums for a solution and I've came accross dependency walker. At first I was missing severall .dll's but I managed to get all the .dll's that I needed. However the error in simulink still persisted and dependecy walker still gave the error:Error: At least one module has an unresolved import due to a missing export function in an implicitly dependent module.I have no clue from which module is this error and I feel both error messages (simulink and dependecy walker) do not give any insight on how to solve the actual problem.I've though about architecture problems since

Invalid MEX-file 'H:\MATLAB\XXXX_sfun.mexw64': H:\MATLAB\XXXX_CTD_sfun.mexw64 is not a valid Win32 application.If I remove one of the SFunctions from the model I no longer get the error. If I put that SFunction back into the model and remove a different SFunction from the model I no longer get the error.There are no global variables.The model worked before the Windows update. I have changed some formulas in the functions but nothing too significant. Running the Matlab code associated with the SFunctions by itself works fine, so I don't think it is a coding bug.Not sure where to go from here. 0 Comments Show all comments Tags sfunctionsmex files Products Simulink Related Content 2 Answers Madhura Suresh (view profile) 0 questions 59 answers 5 accepted answers Reputation: 34 Vote0 Link Direct link to t

This C++ routines calls other routines that are in several other C++ files. I could manage to have everything compiled (i.e. the mexglx file is generated) using the legacy_code tool. However, the following warning is issued: Warning: You are using gcc version "4.4.4-14ubuntu5)". The earliest gcc version supported with mex is "4.1". The latest version tested for use with mex is "4.2". To download a different version of gcc, visit http://gcc.gnu.org The problem arises when I try to generate the S-Function block by issuing the command: legacy_code('slblock_generate', def); At this point, the following error mentioning the GLIBCXX version is raised: ???
