hi there, is it worthwhile to update to the newest release, since that includes heavy on the bela image? and i see we don't have to use gcc anymore, is there a performance benefit in doing that? right now i use heavy on board but i have to compile with:
root@bela:~# make -C ~/Bela PROJECT=granular COMPILER=gcc runlokki hi there, is it worthwhile to update to the newest release, since that includes heavy on the bela image?
I wouldn't say so. Including it on the image is as simple as copying it over, as I think you did before.
Actually the fix that allows to use clang (this one) is not even on the most recent Bela image. clang is definitely faster at compiling than gcc, but I have not checked the performance of the generated code recently. In the past (gcc4.9 / clang3.8), the "Techno world" patch would have the following CPU usage:
libpd 62%
heavy/gcc 39%
heavy/clang 29%so i simply issue a
make -C ~/Bela PROJECT=granular runand if this works i am good to go...
yes
ok, i get some errors. i have now changed the HvLightPipe.c manually, i still had the unpatched version. on to recompile and see if it works.
getting further HvLightPipe compiles, but at the end i get:

did that already. still the same error. maybe it is time to checkout the hvcc from your repo.
You could also try to clean and compile with CPPFLAGS="-O0 -g" then run the project inside gdb and see if that points out something useful about the error.
Also, I hope you are on a >= v0.3 Bela image, right?
giuliomoro Also, I hope you are on a >= v0.3 Bela image, right?
yes i am on v 0.36
the python part stays the same i guess:
python2.7 ~/hvcc/hvcc.py ~/Bela/projects/granular_patch/_main.pd -o /tmp/hvtmp -n bela -g cYes. Can you try with a simpler patch?
also i get a ton of these warnings (excerpt):

...doneyes will try with something simpler. i am now compiling again with gcc and the warnings are very different, i get these:

ok. a simpler patch compiles and runs fine...
ok i have a patch with just a reverb abstraction that fails... same Bus error. i use this reverb in the other patch as well.
so, to investigate further i compile with the flags you wrote and then how do i run inside gdb?
ok i figured it out with gdb, i get this after i try to run the reverb patch inside gdb:
(gdb) run

(gdb) sorry, i need a little assistance now :-)
listwill tell you where that happened.
You can also send me the patch and I will try to have a look. I am very afraid this could be something as horrible to track down as this one, and equally impossible to solve (as it was a bug in clang).
OK, will do when i get home. is it easier for you with a simpler patch or can i send the original patch?
