RPi4 + Buster Lite + oF 0.11.0

[mattc]

Hi!
Some time ago I’ve managed to run oF 0.11.0 examples on Buster Lite running on RPi3. Here’s some details: RPi3 + Buster Lite + oF 0.11.0 = can't run example

Now, I’m trying to do the same on RPi4 but with no luck.
Steps:

1. SD card with fresh 2020-02-13-raspbian-buster-lite.img
2. sudo raspi-config > Advanced > Memory Split > 256
3. sudo apt-get clean && sudo apt-get update && sudo apt-get dist-upgrade
4. wget https://openframeworks.cc/versions/v0.11.0/of_v0.11.0_linuxarmv6l_release.tar.gz
5. sudo mkdir openFrameworks && sudo tar vxfz of_v0.11.0_linuxarmv6l_release.tar.gz -C openFrameworks --strip-components 1
6. sudo rm of_v0.11.0_linuxarmv6l_release.tar.gz
7. cd openFrameworks/scripts/linux/debian && sudo ./install_dependencies.sh && sudo ./install_codecs.sh
8. sudo nano openframeworks/libs/openFrameworksCompiled/project/linuxarmv6l/config.linuxarmv6l.default.mk
   #USE_PI_LEGACY = 0 //commenting this out
9. cd && sudo make Release -C openFrameworks/libs/openFrameworksCompiled/project
10. cd … && sudo nano config.make
    PROJECT_LDFLAGS += -latomic //add the flag
11. sudo make

Compiled without issue, but when trying to run i get:

…and I need to kill it since it just hangs there. Any help?

@mattc I think that is because the Rpi4 uses a different graphics driver than the Rpi3 so the legacy trick you did for the Rpi3 and 0.11.0 won’t work with Rpi4.

For Rpi4 and 0.11.0 you have to have USE_PI_LEGACY = 0 and then select the non legacy driver from raspi-conf

I think @jvcleave has been working on supporting EGL without the X window requirement that our current approach uses. If it works, I’m hoping to add that functionality into the current window approach.

New ofxAddon: ofxRPI4Window

Started a new addon to allow rendering with OF 0.11 without X on the RPI4 No Keyboard/Mouse support and only OpenGL ES 2 (haven’t tried 3 but the RPI4 supports it) Contributors and testers welcome!

[mattc]

Thank you for your post!
Here’s what I’ve done:

1. USE_PI_LEGACY = 0 is back
2. GL driver set to non-legacy
3. sudo make clean and sudo make Release in the openFrameworks/libs/openFrameworksCompiled/project directory
4. sudo make clean, sudo make, sudo make run in one of the examples.

Compiled, but not running. Throwing this:

VER ID IS 10

Hi @mattc

Are you running this headless? Or from the terminal?
You will need to be in an X environment for the GLFW windowing to work.

If you need to run it headless you can use the 3rd party library xvfb to launch apps without a monitor attached.

xvfb-run ./examples/graphics/polygonExample/bin/polygonExample

You might get one glfw error message but it does run the apps okay.
more about that here: https://github.com/openframeworks/openFrameworks/pull/6438#issuecomment-552217431

[mattc]

Not a headless setup. Just a lite system without X environment.

[steeley]

OF doesn’t seem to run without an X environment on RPI4+Buster out of the box.

If you do get it running in the Desktop environment, the performance with OF is not great
and in some cases worse than using an RPI3.
