Hi

I am new to Matlab and I am trying to mex .c files for the ADM1 model. I have the 64bit program and installed the Visio compiler. I did the mex -setup successfully but when I try to mex the .c files I get the following error message:

>> mex adm1_DAE1.c
adm1_DAE1.c
adm1_DAE1.c(19) : fatal error C1083: Cannot open include file: 'simstruc.h': No such file or directory

C:\PROGRA~1\MATLAB\R2010B\BIN\MEX.PL: Error: Compile of 'adm1_DAE1.c' failed.

??? Error using ==> mex at 208
Unable to complete successfully.

Anyone have any ideas what the problem is?

Thanks

This a reply I got from another forum

I assume this is the header file for the simulink tootbox (which I have never used)
do you need to download and install the toolbox? set up paths, etc?

Does that make sense to anyone?

also I have found this

This even happens using Simulinks own S-Function Builder. When I look for the file I see that it is in Matlab\Simulink\Include. Were is the path setup for Simulink mex and why did this change from 2010a?

Fixed per Bug Report 661855, for some reason that doesn't show up on Google!?

I have the same problem ,you can modify the file mexopts.bat .and find the line "set INCLUDE" then add the following string "%MATLAB%\simulink\include;"

To be honest, this still doesn't explain or clear-up anything for me

Does anyone know how I can modify the the mexopts.bat file or do i have to install and update if there was a bug as is indicated in the above message.

OK I have fund the mexopts.bat file and found the line "set INCLUDE" then added the following string "%MATLAB%\simulink\include;"

and that worked

I found the mexopts.bat in C:\Users\*yourUsername*\AppData\Roaming\MathWorks\MATLAB\R2010b and added the string "%MATLAB%\simulink\include;" right after where it says "set INCLUDE = " so that it finally looks something like this:

"set INCLUDE=%MATLAB%\simulink\include;%VCINSTALLDIR%\INCLUDE;%VCINSTALLDIR%\ATLMFC\INCLUDE;%LINKERDIR%\include;%INCLUDE%"

and it worked. Thanks for the help all!
