i thought i'd just pin my own problems onto this thread..
trying to install the HCS library.

i'm following your steps.. so i got the extra header files. done.
created the pd-externals folder. done.
got HCS-0.1 folder, copied it to the board.

when i tried invoking make, i got this:

which to me is very much like a menu from a chinese restaurant. in chinese. in china.
anybody that has succesfully installed that library, by any chance?

It may mean that the external requires a more recent version off Pd than the one that is installed (0.48-2). What does the README say about it? Also, provide a link to the repo pleaee

hmm, i seem to have a mac os version installed on my laptop - one with .pd_darwin files, not .c files like in that download link. the mac folder doesn't contain a MakeFile.
i'm quite sure that one was installed (or at least downloaded) with Deken.

See if on deken there is an ARMv7 build available, or source code. I will not be able to look at this before thursday.

Success! i think.

okay, so i had a closer look at that log file..
'classpath.c', causing the error, is an object from the library i don't need.
so i removed that from the sources in the Makefile.

tried the whole thing again.
i ended up removing the [classpath] and [helppath] objects, since they both messed up the Make process.
it looks like that did the trick - all the others are showing up in the externals project/folder in the IDE now!

kinda eager to test, but need to sleep. tomorrow!

hmm.
the [folder_list] object i'm using still gives me an error when i try to run the patch on bela.
IDE says:
Jan 07 23:22:48 bela stdbuf[747]: folder_list
Jan 07 23:22:48 bela stdbuf[747]: error: ... couldn't create
Jan 07 23:22:48 bela stdbuf[747]: verbose(4): ... you might be able to track this down from the Find menu.

do i still need to explicitly use [declare] (or similar) for bela to use the libraries in the externals folder?
or is there still something not right with the install?

Where are the externals located? If they are in the project folder or in /root/Bela/projects/pd-externals then they should be detected automatically. If this is a single-file library, then you may have to manually load the library ( I think [declare] is the right object

they are in pd_externals/hcs.
i guess i need to specify that subfolder as a path? and if so, how?

ok, after much trial and error:
adding a [declare -path /root/Bela/projects/pd-externals/hcs] object gets it to work.
i tried just to [declare] relative paths instead of the full path but that wouldn't work for some reason.

/// edit: of course, simply using [hcs/folder_list] works just as well. NEED NEW EYEBALLS.

learning every day.
and here was me thinking running a Pd file on hardware would be a no-brainer :/
anyway, this is a relief. happy camper!

    Remork adding a [declare -path /root/Bela/projects/pd-externals/hcs] object gets it to work.

    Yeah that's normal for Pd too, however the "problem" is that in the desktop version you can set paths through the global options, so you don't need them in the patch itself

      so i noticed 🙂

      anyway, guess it should become a habit to declare used libs from within the patch.. can imagine that might come in handy when sharing or returning to patches anyway. seems good practice.
      onwards!

      I now decided to gather pre-built externals here. I won't rebuild old ones, but any I will build or rebuild in the future will go there.

      Hello!

      I'm trying to install the ipoke~ external. I tried the above examples for ggee and cyclone, and also helmhotz~ (thank you for these step by step!), which were successful. I tried to apply the same process for ipoke~ with its specific makefile but i cannot find the way to make it work. I'm new using Bela, i'm good with puredata but the rest... Still a bit confusing with my poor coding skills...

      I got the source code here: http://puredata.info/Members/ipoke/ipoke_v.3_test1.zip/view
      I tried copying the pd_linux only on pd-externals (in the IDE) but didn't made my objects work. i don't find the right way to compile it. Here is what I get when I try the "cyclone" way in the src file.
      alt text

      I tried to replace the parameters with LINUXFLAGS like in the helmholtz~ example, but this became very complicated.. I'm gonna try again, in between, would you have any clue? or is there another way? Thank you so much for your help!

        marylougarou I tried copying the pd_linux only on pd-externals (in the IDE) but didn't made my objects work

        that wouldn't work: it's probably a .pd_linux file for x86 architecture, not for ARM.

        marylougarou Here is what I get when I try the "cyclone" way in the src file.

        the issue here is that the -Wall and -Werror flags mean, respectively "show all warnings" and "treat all warnings as fatal errors". In turn this causes the compilation to fail. The easiest fix is to edit the Makefile and remove -Werror from LINUXCFLAGS. I would also remove them_pd.h that is in that folder and add to LINUXCFLAGS: -I/usr/local/lib/include: the PD_INCLUDE variable you are passing at the command line is ignored in this Makefile. At the end you'd have the following in LINUXCFLAGS:

        LINUXCFLAGS = -DPD -DUNIX -DICECAST -O3 -funroll-loops -fomit-frame-pointer \
    -Wall -W -Wshadow -Wstrict-prototypes -fno-strict-aliasing -I/usr/local/include/libpd \
    -Wno-unused -Wno-parentheses -Wno-switch -fPIC

        With this, it builds fine for me.

            is it possible that you pasted all the lines in one line? Then you should remove the \. like this:

            LINUXCFLAGS = -DPD -DUNIX -DICECAST -O3 -funroll-loops -fomit-frame-pointer -Wall -W -Wshadow -Wstrict-prototypes -fno-strict-aliasing -I/usr/local/include/libpd -Wno-unused -Wno-parentheses -Wno-switch -fPIC

              for future records, I am uploading here the externals I build, including all build instructions. If you don't find your favourite external there, hopefully the instructions I used to build the others will help you building the ones you are interested in.

              Hello giuliomoro! First of all, many thanks for your great support here!

              Please, is there a way for you to share the compiled libpd with all the Pd-l2ork externals?
              I'm pretty interested on the fluid~ object so I could play SF2 soundfonts on Bela.

              I went here https://github.com/BelaPlatform/Bela/issues/621 but I'm not sure all the externals from l2ork are there.

              Thank you in advance!
