using "modele reference" with RTW

Hello

sorry for my not really fluent english

here is my problem :

I create a simple model with simulink "model.mdl"

"inline parameters" is true and "ModelReferenceCompliant" is on

I create a simple model "test.mdl" using "model.mdl" with block "modele reference"

boths model RTW target file are"igc.tlc" (owner target)

when I build "test.mdl" I have this error : lcc preprocessor error: model_main.c:14 Could not find include file "rtmodel.h"

when I look in "model_igc_rtw" directory (where is my generated "model_main.c") i find "rtmodel.h"

lcc is called by : "C:\PROGRA~1\MATLAB\R2009a\sys\lcc\bin\lcc -c -Fomodel_main.obj -DUSE_RTMODEL -DMODEL=model -DRT -DNUMST=1 -DTID01EQ=0 -DNCSTATES=0 -DMT=0 -DHAVESTDIO -I. -I..\..\.. -IC:\PROGRA~1\MATLAB\R2009a/simulink/include -IC:\PROGRA~1\MATLAB\R2009a/extern/include -IC:\PROGRA~1\MATLAB\R2009a/rtw/c/src -IC:\PROGRA~1\MATLAB\R2009a/rtw/c/libsrc -IC:\PROGRA~1\MATLAB\R2009a/rtw/c/src/ext_mode/common -IC:\PROGRA~1\MATLAB\R2009a/rtw/c/src/ext_mode/tcpip -IC:\PROGRA~1\MATLAB\R2009a/rtw/c/src/ext_mode/serial -IC:\PROGRA~1\MATLAB\R2009a/rtw/c/src/ext_mode/custom -IC:\Simulateurs\sources\NantillaEsouloubre\Simulateur\test\slprj\igc\model -IC:\Simulateurs\sources\NantillaEsouloubre\Simulateur\test -IC:\PROGRA~1\MATLAB\R2009a/toolbox/dspblks/src/sim -IC:\PROGRA~1\MATLAB\R2009a/toolbox/dspblks/src/rt -IC:\PROGRA~1\MATLAB\R2009a/toolbox/commblks/commmex -IC:\PROGRA~1\MATLAB\R2009a\sys\lcc/include -I..\..\..\slprj\igc\_sharedutils -noregistrylookup model_main.c " which seems ok to me

if somebody has an idea about my problem

thanks Fabien

Could you try using grt.tlc instead and see if you receive the same error? igc.tlc seems like a third-party target.

Hello

if I copy "rtmodel.h" to "C:\PROGRA~1\MATLAB\R2009a/simulink/include" directory the error diseapear but I havs still those errors :

Error model_main.c: 77 syntax error; found `*' expecting `;'

Error model_main.c: 107 syntax error; found `*' expecting `;'

Error model_main.c: 117 undeclared identifier `rtU' ...

where :

77 extern RT_MODEL *MODEL(void);

107 RT_MODEL *S;

[Kaustubha Govind]

Fabien, rtmodel.h is generated anew for each model, so it's a bad idea to copy the one generated for one specific model to a MATLAB toolbox directory. Again, could you please try with grt.tlc and report back the results?

[Kaustubha Govind]

Also, delete the copied rtmodel.h from the simulink/include directory before you try grt.tlc

[Mark]

The compiler errors that you are getting indicate that the "rtmodel.h" file that you are using is incorrect/out-of-date. Using line 77 as an example, the compiler sees first sees "extern RT_MODEL". Because the "rtmodel.h" header file is incorrect, it does not contain the typedef for "RT_MODEL". From there, through some quirks and defaults in the specification of the C language, the compiler assumes that this actually means "extern int RT_MODEL(...)", which is the default behaviors of "this function returns an int" and "any parameters are valid". Once the compiler has made those assumptions, the "*" doesn't make sense to it.

thanks for answers

it is working with grt.tlc target

when I check matlab help, my target (igc_lcc.tmf) seems to implement everything needed for modele reference, but doesn't work

what means "third-party target" ?

[David Cabral]

A third party product refers to files that you obtained from someone other than MathWorks. In this case the target file igc.tlc is not part of a MathWorks shipped product.
