On your board,at the path /root/Bela/scripts/hvresources/render.cpp you should have a wrapper for heavy that should be compatible with your version of the Bela core core.
Heavy, Pd and Enzienaudio

giuliomoro Thanks for your instructions!
I am having some trouble installing the files from the requirements.txt on my laptop (I am working with ubuntu 18.04) could you help me?
I have python 2.7 and 3.6 on my laptop. (I set 2.7 as default).
i get the following errors:
ERROR: Command errored out with exit status 1:

i tried installing jinja2 separately, it installs succesfully, but I still get an error:
ERROR: flask 1.0.2 has requirement Jinja2>=2.10, but you'll have jinja2 2.7.3 which is incompatible. (do you know if I could just try to upgrade jinja2 to a higher version, or I need to create a situation where I can run 2.7.3?)
- Edited
I actually don't know. This seems python dependency hell ... I guess my best recommendation would be nuke the whole thing and start over.
BUT let's try to make some sense of it. All the errors refer to python3.6, which makes me suspect there is something wrong in your path or default python? Maybe this could be a good starting point to investigate.
yannick (do you know if I could just try to upgrade jinja2 to a higher version, or I need to create a situation where I can run 2.7.3?)
I have no idea!
Sorry I can't be of much help.

thanks for your reply! so i restarted the whole process. on the board, the compiler seems to be running fine, i successfully compiled the basic (example) pd patch to the Bela. but in the project i'm workig on, i still get a lot of errors in the link process, (almost all of them got something to do with the render.cpp file, "undefined reference to 'libpd_...') i have recently updated my bela image to 0.3.7a .

Can we see the content of the render.cpp file? I suspect that it is a render.cpp for libpd and not for heavy.

}Ok, can you also tell me what is the output of grep v0 /etc/motd, and how you updated your code last?
giuliomoro the output from grep v0 /etc/motd is Bela image, v0.3.7a, 16 October 2019. i did not update this code myself, so i can't answer this immediately.. @Fedde could you specify this further?
ok if it's the latest image, then I don't need further detail. Can you confirm if you have a _main.pd file in the project folder?
giuliomoro yes i do have a _main.pd file in the project folder. (does it matter that it has a subpatch inside?)
yannick a _main.pd file in the project folder. (does it matter that it has a subpatch inside?)
it doesn't matter that it has a subpatch inside, as long as it is located in the project folder and not in a subdirectory of the project folder.
The above file compiles and runs fine for me. Try one of the following:
- If you are building with the IDE, go to the Settings tab and add to the
Make Parameters:box the following:AT=. - If you are building using the
scripts/build_project.shscript from the host, add-m "AT="at the end of the command line - if you are building directly with
makeon the board, simply appendAT=to themakeline
The three actions above will give a more verbose output, please run one of them and paste the output here.

Automatically detected PROJECT_TYPE: cppsuggests that there is no _main.pd file in the project folder. Can you show the output of ls /root/Bela/projects/NonagonBar_Heavy ?
I still don't understand why you have all the files generated by the Heavy compiler, but you are using a render.cpp file that is for libpd. Could it be the case that you are trying to build a Heavy project, but including the wrong custom render.cpp in it?
- Edited
giuliomoro thanks a lot!! actually that's what happened. I am trying to make a heavy project out of my pd project. it compiles succesfully after i just used the render.cpp file from ~/Bela/scripts/hvresources/render.cpp. Only i have to alter the render.cpp file, as it is now not reading the sensor values (it just prints zero's), also the setup function for the sensors has got to be in there i think (or should i add these in a different location?) . Is there any way to convert the libpd version of the render.cpp file to one that works with heavy? or do i have to do that manually? (the lib pd version of the functions i wish to add is marked with //MODIFICATION START and //MODIFICATION END in the pasted render.cpp file above.)could you give me some directions?
- Edited
The process has to be done manually and it consists in applying to the default heavy render.cpp the same changes you applied to the default libpd render file. Part of that is straightforward (e.g.: the trill code), but sending messages to heavy has a different API to that to send them to libpd. It is explained here.
I tried to port your changes, see if it works: here
Thanks!! It compiled succesfully, but it now gives me either 0 or 26 as output, instead of the desired floating point values. I probably forgot to include something, or forgot to mark some code i included. I'll have a good look at the scripts, ill let you know when it works (or doesn't work )
The way i understand my code, what the below is doing is creating a message with numSensors+1 elements. The first element of the message is the number of sensors, and the following elements are the readings for each of the elements, which is my understanding of what your code was also doing. But I may be wrong on both accounts.
int numElements = touchSensorMain.numSensors() + 1;
HvMessage *msg = (HvMessage *) hv_alloca(hv_msg_getByteSize(numElements));
hv_msg_init(msg, numElements, 0.0);
hv_msg_setFloat(msg, 0, touchSensorMain.numSensors());
double delayMs = 0.0;
for(unsigned int n = 0; n < touchSensorMain.numSensors(); ++n)
{
hv_msg_setFloat(msg, 1 + n, touchSensorMain.rawData[n]/(2048.f));
}
hv_sendMessageToReceiver(gHeavyContext, bela_trill_main_hash, delayMs, msg);oh that makes so much sense now! i want to read 26 incoming signals and make a list out of it, this code actually added numSensors to that list as the first element. there is also a function which subtracts the highest incoming value from all elements in the list. because i only sent and printed the first value of the list to test if the code actually worked, it was always showing me 26 and (26-26)=0 :') when i altered the patch to send and print all incoming values, everything worked just fine. thank you so much for helping me through this process!
no problem. Hopefully we will make it easier to modify the default heavy/libpd wrappers. For sure we are going to add Trill by default to these, so that you won't have to do this.
