S-function builder does not find limits.h

Hi,

I'm trying to create a very simple s-function, just feeding through the input, using the s-function builder. I get an error saying that limits.h cannot be found. Limits.h is included by math.h, which I included. It does not help to add the path to limits.h, it still cannot be found.

regards, Fredrik

error message:

Which C compiler do you use? I.e., when running "mex -setup", which did you choose?

I have the same problem. I'm using Microsoft Software Development Kit (SDK) 7.1 compiler. Before of I can see that problem I can't compile my s-fuction's file and the matlab show the messagem below:

Error using mex (line 206) Unable to complete successfully.

Error in C:\Program Files (x86)\MATLAB\R2012a\toolbox\simulink\simulink\+legacycode\@LCT\compile.p>compile (line 268)

I searched some solution and I found a group talking about and say to add the string "%MATLAB%\simulink\include" in the file mexopts.bat in the line "set INCLUDE" but the problems remains.

What should I do? I appreciate any help.

limits.h is a standard C header that should come with your compiler. Could you try doing a search in your SDK installation and see if it exists. Also, when you run "mex -setup", make sure that MATLAB is able to find your compiler automatically. If you have to provide the path manually, there might be something wrong in the configuration.

Well in my SDK installation the header does not exist indeed, then I added limits.h in the matching path but I still can't compile my project. The following error occurs:

### Start Compiling patientReaderSfun mex('patientReaderSfun.c', 'C:\Users\Melqui\Documents\MATLAB\model\ExtendedGPCA\PatientDataReaderLCT.c', '-IC:\Users\Melqui\Documents\MATLAB\model\ExtendedGPCA') PatientDataReaderLCT.obj : error LNK2005: _selectedLine already defined in patientReaderSfun.obj Creating library C:\Users\Melqui\AppData\Local\Temp\mex_Zllohm\templib.x and object C:\Users\Melqui\AppData\Local\Temp\mex_Zllohm\templib.exp patientReaderSfun.mexw32 : fatal error LNK1169: one or more multiply defined symbols found

Currently I'm working on GPCA pump model of FDA and I can't execute the model because of these problens.
