Good morning at all,

I've got a problem while i try to run a function block that i create.
I followed the step 4 of the guide relative to create a function block and the guide on how to compile FORTE from source. The function blocks present in the library when i download the IDE work fine but the block i create doesn't work.

Can you please help me solving this problem?

I leave the files generated when i export the FB (CMakeLists.txt, Controller.cpp and Controller.h) and the photo related to the ECC (Controller_ECC.png) of the function block in the attachment and the resource view ( Resource_view.png) in order to let you know how i connect the block to the resource (in the application view there's only this block).

below here there's the output in the deployment consolle


<Request Action="QUERY" ID="1">
<FB Name="*" Type="*"/>
</Request>

<Response ID="1"/>


<Request Action="CREATE" ID="2">
<FB Name="Controllore" Type="EMB_RES"/>
</Request>

<Response ID="2"/>


<Request Action="CREATE" ID="3">
<FB Name="Controller" Type="Controller"/>
</Request>

<Response ID="3" Reason="UNSUPPORTED_TYPE"/>


<Request Action="CREATE" ID="4">
<Connection Destination="Controller.INIT" Source="START.COLD"/>
</Request>

<Response ID="4" Reason="NO_SUCH_OBJECT"/>


<Request Action="CREATE" ID="5">
<Connection Destination="Controller.INIT" Source="START.WARM"/>
</Request>

<Response ID="5" Reason="NO_SUCH_OBJECT"/>


<Request Action="START" ID="5"/>

<Response ID="5"/>

Down here there are all the messages appeared in the simulated device manager

INFO: T#4221071617143: FORTE is up and running
INFO: T#4221071772174: Using provided bootfile location set in CMake: forte.fboot

Thanks to who will help me and have a good day

NO_SUCH_OBJECT means that the 4diac FORTE you are running does not have the FB with the given type name in its internal typelibrary. There are two common reasons for that:
- you are not running your self compiled 4diac FORTE
- you have not activated the module with your fb and therefore it is not compiled into your forte

Thanks for the answer Mr. Zoitl, i found the problem: in step 7 in the building FORTE from source there's written that will appear FORTE_MODULE_EXTERNAL_EXAMPLE_TEST (in my case it could be FORTE_MODULE_EXTERNAL_ExportedFBs because i saved my exported fb in /home/nick/Scrivania/progetti_4diac/Progetto/ExportedFBs) but it never appears even i press configure multiple times

Could you please explain me how to solve this issue?

I leave you my cmake screen in the attachments after i press configure for the second time.

Thanks in advance

ok, i solved all the problems, now the block works well. thank for the help.

for who is reading this discussion the folder you have to select for the external modules is the folder which contains the folder with the .h .cpp and the CMakeLists.txt (in my case is /Scrivania/progetti_4diac/Progetto).

thanks for the help Mr Zoitl and have a good day,

Nicolò
