sorry I missed a projects in my paths. Should have been:

what do you get with ls /root/Bela/projects/pd-externals/else/above~.pd_linux ? and then find /root/Bela/projects/pd-externals -type d and then find /root/Bela/projects/pd-externals -type f | grep pd_linux?

    FatJak Now i'm trying, with command lines to place Else & Cyclone libraries in /root/Bela/pd-externals

    that should be /root/Bela/projects/pd-externals

      Thanks again @giuliomoro

      Since few hours, i feel free to make some experiences.
      - I have selected only the .pd objects in my computer Else library and made from it a folder.zip file
      - I have upload/install it in /root/Bela/pd-externals and i modified the main.pd path object to these externals
      - I have discover that there his very few objects that could't be created.
      Here is the list:
      else/fold -1 1
      else/args -
      else/swap2
      else/rand.f -1 1
      else/rescale -1 1 0 127
      s2f~

      I have tryed to make .pd abstractions from these graphical objects.
      It seems not working.
      (kind of bruteforce experimentation)

        giuliomoro

        After cleanup, reinstall as you tell me, this is what I get with
        ls /root/Bela/projects/pd-externals/else/above~.pd_linux

        /root/Bela/projects/pd-externals/else/above~.pd_linux

        and then

        /root/Bela/projects/pd-externals/cd

        and then

        rescale 10 10000
        s2f~

        Hmmm... what would I do without this three little seeds ? Nothing, with my "work in progress" patch.
        Thanks @giuliomoro to let me dive deep into the surface of command lines.
        Even if I only understand the reflect of it.

          (which includes compiled externals s2f~.pd_linux and rescale.pd_linux)
          and furthermore all the .pd abstraction files, which should include at least /root/Bela/projects/pd-externals/else/brown.pd.

          I am wondering what has happened there. Try the following instruction step-by-step, please:

          • from the Bela IDE, delete the project pd-externals
          • download this archive on your computer https://github.com/BelaPlatform/Bela/files/10212285/else-v1.0-rc4-93-g0c64c285.zip
          • drop it in your on top of the Bela IDE. When asked the name of the new project you want to create, type pd-externals and click "create project"
          • now create a new project and copy on it a _main.pd file with only these objects in it:
            [brown] [s2f~] [rescale]
          • run the project and verify that you get no couldn't create errors when you start it

          Note that the procedure above will put all the files in /root/Bela/projects/pd-externals and not in /root/Bela/projects/pd-externals/else. This is good enough for testing. If this works, you can move them with:

          mv /root/Bela/projects/pd-externals /tmp/else
mkdir -p /root/Bela/projects/pd-externals
mv /tmp/else /root/Bela/projects/pd-externals/

          then modify your _main.pd so that it contains only these objects:

          [brown]
[s2f~]
[rescale]
[declare -path /root/Bela/projects/pd-externals/else]

          and verify it still runs without couldn't create errors.

            giuliomoro Thanks. There is hope !

            I don't understand where to upload the else-v1.0-rc4-93-g0c64c285.zip
            with the information "drop it in your on top of the Bela IDE".
            If it's on the top of Bela IDE, I don't know how to do it.

            In the "create new project" section, clearly, I have to select the "Pure data" type ?

            "Note that the procedure above will put all the files in /root/Bela/projects/pd-externals and not in /root/Bela/projects/pd-externals/else"
            I don't understand with which procedure I can avoid to create a else folder unzipping the else-v1.0-rc4-93-g0c64c285.zip

                FatJak I don't understand where to upload the else-v1.0-rc4-93-g0c64c285.zip
                with the information "drop it in your on top of the Bela IDE".

                If you drop the zip archive on the IDE you should be prompted with a dialog to create a new project from the contents of the zip archive itself.

                  "drop the zip archive on the IDE"
                  Crazy. I hadn't thought I had to take it literally.

                  giuliomoro

                  So.
                  Unzipping the file gave me
                  Error opening file render.cpp: file does not exist.
                  But I could see objects in
                  /root/Bela/projects/pd-externals

                  Running the _main.pd with [brown] [s2f~] [rescale]
                  gave me errors:

                      else/swap2
                      error: ... couldn't create
                      else/rand.f -1 1
                      error: ... couldn't create

                      rely on having the stuff in the else/ folder.

                      and this

                      FatJak error: ../pd-externals/rescale.pd_linux: /lib/arm-linux-gnueabihf/libm.so.6: version GLIBC_2.29 not found (required by ../pd-externals/rescale.pd_linux)

                      is because I built else with a too-new version of the board. I am going to redo it on the same version you have.

                          ok I rebuilt it and it is now available . Please follow the instructions below:

                          Try the following instruction step-by-step, please:

                          • download this archive on your computer
                            https://github.com/BelaPlatform/Bela/files/10228145/else-v1.0-rc4-93-g0c64c285.zip
                          • drop it in your on top of the Bela IDE. When asked the name of the new project you want to create, type pd-else and click "create project". Wait for a few seconds while it is done.
                          • when done, you will get an error "couldn't open render.cpp". That's fine, press "Cancel"
                          • run the following in the console at the bottom of the Bela IDE so that the externals go in the right place:
                            rm -rf projects/pd-externals;
                            mkdir -p projects/pd-externals;
                            mv projects/pd-else projects/pd-externals/else;
                          • now create a new project and copy on it a _main.pd file with only the following objects in it: 
                            [brown]
[s2f~]
[rescale]
[declare -path /root/Bela/projects/pd-externals/else]
                          • run the project and verify that you get no "couldn't create" errors when you start it
