Problem in creating .dll from simulink model

Hi, I developed one simulink which include S function builder which links to C code.Now I want to generate .dll from that model.When I am trying to build the model using RealTime Workshop,matlab is throwing the following error Linking IFM_ULP_Test.exe "C:\Borland\bcc55\bin\ilink32" -ap -x @MAKE0000.@@@ Turbo Incremental Link 5.00 Copyright (c) 1997, 2000 Borland Fatal: Unable to open file 'CANDRIVER.OBJ' Actually,I am maintaining some folder structure and same paths are used to generate mex file from s function builder.Plz anyone help me in fixing this. Regards Sai

What is CANDRIVER.OBJ exactly? Is it the S-function itself, or a file that the S-function calls into?

[sai vasavi]

Thanks for your reply Kausthubha.CANDRIVER is a source file included in S function builder. I have 1 qq that does will serach for model related files in the current working matlab path ? If yes means,Plz tell me is there any way to set paths in RTW.

[Kaustubha Govind]

Where do you enter the list of additional source files to link against? Have you configured this in the 'Libraries' pane of the S-function Builder?

[sai vasavi]

Yes.I configured this LIbraries of S function builder.Now I am facing this error when i am trying to generate code from RTW.

[Kaustubha Govind]

And you mention the file name as CANDRIVER.c and not CANDRIVER.OBJ, correct? Could you turn on Verbose build on the Configuration Parameters > Code generation pane, try generating code again, and see if CANDRIVER.c is being compiled?

[sai vasavi]

Thanks for your Kaustubha.Now i can able to generate the .exe from RTW.By building the model in verbose build model I can able to clear all my errors. Now,I found one file which describes the procedure to create .dll from simulink model and it is the link. http://www.mathworks.in/matlabcentral/fileexchange/9709-from-simulink-to-dll-a-tutorial. I am getting error in matlab generated make file when trying to link and compile all the files using command gmake -f (modelname).mk in modelname.mk at 107:*** missing separator stop. and below attached is the make file # Copyright 1994-2007 The MathWorks, Inc. # # File : grt_lcc.tmf $Revision: 1.26.4.20 $ # # Abstract: # Real-Time Workshop template makefile for building a PC-based # stand-alone generic real-time version of Simulink model using # generated C code and # LCC compiler Version 2.4 # # This makefile attempts to conform to the guidelines specified in the # IEEE Std 1003.2-1992 (POSIX) standard.

Sai: If you are able to generate code from official MathWorks products, but are only having trouble using that File Exchange submission, I'd recommend contacting the author directly since there might be a bug in their files.
