make it work with raspberry pi 3 b+ and latest openframework

[nanu-c]

Set up the rpi 3 b+

• get latest raspbian as described on https://www.raspberrypi.org/downloads/raspbian/

• Do the things in section 3 and 4 from https://github.com/googlecreativelab/open-nsynth-super/tree/master/linux#3-prepare-the-os

get nsyth from git

$ wget https://codeload.github.com/googlecreativelab/open-nsynth-super/zip/master
$ unzip master && rm master

Set up the firmeware

• follow the guide from here https://github.com/googlecreativelab/open-nsynth-super/tree/master/firmware#installation-guide -> get en.stm32cubef0.zip from http://www.st.com/en/embedded-software/stm32cubef0.html and put in /home/pi/open-nsynth-super-master/firmware/

$ cd /home/pi/open-nsynth-super-master/firmware/
$ unzip en.stm32cubef0.zip 

• get the depencies
  $ cd /home/pi/open-nsynth-super-master/firmware/utils && sudo ./install_dependencies.sh
  -> this takes a while

• don't do this $ mv STM32Cube_FW_F0_V1.9.0 cube it gives then the error
  make: *** No rule to make target '../STM32Cube_FW_F0_*/Drivers/CMSIS/Device/ST/STM32F0xx/Source/Templates/gcc/startup_stm32f030xc.s', needed by '../bin/main.elf'. Stop.

• flash chip
  $ make install

sudo /home/pi/open-nsynth-super/firmware/openocd/bin/openocd --file openocd.cfg --command "program ../bin/main.elf verify reset exit"

copy audio files

• https://github.com/googlecreativelab/open-nsynth-super/tree/master/linux#4-copy-audio-files

Set up latest openframework from git

• get latest openframeworks from git
  $ cd ~ && mkdir opt/ && cd opt/ && git clone --depth=1 https://github.com/openframeworks/openFrameworks.git
• rename the openframeworks folder to be compatible with manual
  $ mv openFrameworks of
• get openframeworks dependencies
  $ cd of/scripts/linux/debian && sudo ./install_dependencies.sh
• get libs for openframeworks
  $ cd ~/opt/of/scripts/linux && download_libs.sh
• copy the files from https://github.com/googlecreativelab/open-nsynth-super/tree/master/app/open-nsynth to $ mkdir /home/pi/opt/of/apps/open-nsynth && cp -r /home/pi/open-nsynth-super-master/app/open-nsynth /home/pi/opt/of/apps/open-nsynth/
• replace in the code Poco::FastMutex with std::mutex -> this is in various files
• add ofxPoco to addons.make
• build the app in ~/opt/of/apps/open-nsynth/open-nsynth with
  $ make -j4 -> this takes a while
• get the settings.json in the right place https://github.com/googlecreativelab/open-nsynth-super/tree/master/linux#4-copy-audio-files
• test if it's running with
  $ bin/open-nsynth

get nsynth dependencies

$ cd ~/open-nsynth-super-master/linux

• edit ./nsynth-setup.sh and edit the section replace every gstreamer0.10 with gstreamer1.0

install_deps() {
    apt-get update
    apt-get install -y i2c-tools python-smbus gdb-arm-none-eabi gcc-arm-none-eabi \
        git autoconf libtool make pkg-config build-essential \
        libcairo-dev gstreamer1.0-dev gstreamer1.0-x \

        libegl1-mesa-dev libgles1-mesa-dev libgles2-mesa-dev libassimp-dev \
        librtaudio-dev libboost-filesystem-dev
}

• remove the follow section:

setup_openframeworks() {
    if ! [ -e /home/pi/opt/of ]
    then
        echo "Fetching openFrameworks"
        mkdir -p /home/pi/opt
        (
            cd /home/pi/opt
            curl http://openframeworks.cc/versions/v0.9.8/of_v0.9.8_linuxarmv6l_release.tar.gz | tar -xzf -
            mv of_v0.9.8_linuxarmv6l_release of
            #sudo of/scripts/linux/debian/install_dependencies.sh
        )
    fi
}

• run it $ sudo sh ./nsynth-setup.sh
• reboot $ sudo reboot

[nanu-c]

and it works ;)

[nsynthsuper]

Thanks so much nanu-c – will leave this issue open for others to reference.

@nsynthsuper @nanu-c is it possible to make an image for this, I've been hitting a lotttt of snags bouncing between these two instruction sets and cannot always find the correct packages referenced. Please and thanks!
