PIL Block build error

Hi, when building a PIL Model Block i get the following error:

undefined first referenced symbol in file

--------- ----------------

error: unresolved symbols remain error: errors encountered during linking; "./CustomMW/PIL_Try2.out" not built

Can you help me resolve this? Regards, Werner

[Kaustubha Govind]

What target are you building for? What is the System Target File (.tlc) that you've selected?

[Werner]

What i did was i converted an atomic subsystem to a model block and added my Target preferences block in both the atomic subsystem and the model block. The intended target is a SD eZdsp F2808. I get the error after starting the simulation and specificly while building the makefile. There was no tlc-folder made in my model folder..

[Werner]

Well, right now i realized there`s more to this then i expected...

I ran checkEnvSetup and got this:

>> checkEnvSetup('ccsv4','F2808 eZdsp','check')

I run CCSv4.2.4, seems like that is the problem... or at least a problem too?

I got a Windows 7/64-bit machine here and i really struggle finding the right combination of MATLAB-versions and third-party-program-versions to be able to do just a little profiling in Simulink...

I really just want to build small systems with just a few mathematic operation to compare them, but i can do that one at a time etc..

Is this possible?

I read the best way would be to use CCSv3 an a 32-bit machine with an older Matlab-Version, so i just wanted to ask if it`s possible to do PIL-profiling in my environment?

Answer 1

[Kaustubha Govind]

The documentation section Example — Performing a Model Block PIL Simulation via SCI Using Makefiles seems to suggest that CCSv4 can also be used for PIL profiling. I don't have too much experience in the Embedded Targets area, so I won't answer will complete authority, but I think for now, you should just try and get past the compiler error.

AFAIK, the Target Preferences block must only be present at the root-level of the model, and not inside subsystems. Could you try that and see if the error goes away?

[Werner]

Sure i can do that:

So when i have the Target preferences block only at the root level i get the following error:

"The call to idelink_ert_make_rtw_hook, during the entry hook generated the following error:

The model or subsystem "Atomic_Subsystem" must contain a Target Preferences block. Place a Target Preferences block inside this model or subsystem.

The build process will terminate as a result."

And when i got the Target preferences block only in the subsystem i get this error:

"The call to idelink_ert_make_rtw_hook, during the entry hook generated the following error:

The model or subsystem "<Model_Name>" must contain a Target Preferences block. Place a Target Preferences block inside this model or subsystem.

The build process will terminate as a result."

Funny thin is in the command window i get the message that the build process completed:

".

and after that the error occurs.

[Werner]

So i just installed CCS v4.1.0 and now get this from checkEnvSetup:

and when i try running the PIL-Simulation i get this in the MATLAB Command-Window:

Do i have to include something specific in the linker command in the xmakefilesetup?

[Werner]

Sorry for the bad formatting by the way, i`ll try to separate the code/text-parts better next time!

[Kaustubha Govind]

Ah. So I guess you were right about needing Target Pref blocks inside atomic subsystems too. :)

If possible, could try running the demo model described in the documentation link from my answer? That will tell us if the issue is with your installation, or your model.

[Werner]

Hi,

just tried that...

Got the following error:

"When the build format is "Makefile", PIL cannot use the IDE debugger to communicate with your target. If your target supports Serial Communication Interface (SCI) or TCP/IP, configure PIL to use those instead. See the documentation for more information."

Seems like i have to set a right ConnectivityConfiguration for that cause for SD eZdsp F2808 the "Makefile" build format is set automatically...

I think i`ll try that: http://www.mathworks.de/help/toolbox/ecoder/ug/bruy_tf-1.html#bruy017

Or am i interpreting the error wrong?

Anyways, i think i`ll call it a day and will start my weekend, hope to be able to post some accomplishment on Monday (in Austria) :)

Thanks for your help, have a nice weekend!

[Kaustubha Govind]

Good luck! Sorry, I haven't done this before, so any advice I can give will be limited to what I read in the documentation. :)

[Werner]

Hi, no worries, i`m thankful for every hint!

So i installed CCS 4.1.0 but checkEnvSetup doesn`t seem to recognize the installation:

---------------------------------------------------------------------------------------------------------

Got any idea why or what to do?

[Kaustubha Govind]

Not sure, but maybe your CCS installation was not done completely/correctly. I think checkEnvSetup checks the Windows Registry to find the key corresponding to CCS, not perhaps that was not populated correctly. Try running the CCS installation "as administrator" and try again? If that doesn't work, try calling MathWorks Tech Support.

[Werner]

Hey,

sorry for the long pause...

Yeah, running the Program as admin solved the problem of Matlab not recognizing the installation.

However, seems that IDELink is not supported for CCS4 and F2808.

I give up, maybe i`ll come back to it someday, but for now i`ll stop working on this topic.
