Exactly the same happens using pip install unicornhat

Gadgetoid commented 9 years ago

Could you supply some pertinent details on your OS?

cat /etc/*-release
ld -v
gcc -v
uname -a
t3chguy commented 9 years ago

I will do shortly, currently trying another image to see whether its directly related to that. It was the Ubuntu Mate image available on the Raspberry Pi Downloads Page, I will get back here after testing Raspbian, and go back to Mate to get you the details you need.

Thanks

Gadgetoid commented 9 years ago

We currently don't test on, or support, anything but Raspbian and I've got a suspicion that Unicorn HAT will be particularly tricky to get working with Ubuntu Mate due to the somewhat arcane way in which it works.

I'll never say never, though. I'm downloading Ubuntu Mate right now to see if I can get it working myself. I'm currently supposed to be busy with something else, though, so I might be a while getting back to you!

t3chguy commented 9 years ago

Thanks for testing it yourself regardless! Raspbian is almost installed on a secondary card so I can test if it works for me there.

t3chguy commented 9 years ago

As expected, works blindingly on Raspbian

Managed to get it to compile by just adding -fPIC into the library Makefile. I can't push this as a fix until I've tested it on Raspbian, but I've got a working Unicorn HAT on Ubuntu Mate- much to my surprise!

You should replace your python/rpi-ws281x/lib/Makefile with:

all: lib test

lib:
    gcc -o ws2811.o -c -g -O2 -Wall -Werror ws2811.c -fPIC
    gcc -o pwm.o -c -g -O2 -Wall -Werror pwm.c -fPIC
    gcc -o dma.o -c -g -O2 -Wall -Werror dma.c -fPIC
    gcc -o board_info.o -c -g -O2 -Wall -Werror board_info.c -fPIC
    gcc -o mailbox.o -c -g -O2 -Wall -Werror mailbox.c -fPIC
    ar rc libws2811.a ws2811.o pwm.o dma.o board_info.o mailbox.o
    ranlib libws2811.a

test:
    gcc -o main.o -c -g -O2 -Wall -Werror main.c
    gcc -o test main.o libws2811.a

clean:
    -rm ws2811.o pwm.o dma.o board_info.o mailbox.o
    -rm libws2811.a
    -rm test
t3chguy commented 9 years ago

@Gadgetoid I tried your rendition of the Makefile, and it looks fully functional in Ubuntu :D

I really appreciate you getting it to work, hopefully it'll also work on Raspbian so this change can be pushed into the repo.

Thanks

Edit, I will clone and modify it just as I have done again, but on Raspbian to run a test to see whether it breaks it there, I'll be using the Raspbian installed via NOOBS

t3chguy commented 9 years ago

@Gadgetoid I can confirm that on Raspbian even with the -fPIC arguments it both compiles correctly and functions identically to the PyPi package. Hope this fix gets pushed into the repo as then it'll add compatibility for Ubuntu Mate for other users.

Thanks again for getting this working!

Gadgetoid commented 9 years ago

I've now tested this on Raspbian and pushed the -fPIC fix into the Makefile: https://github.com/pimoroni/unicorn-hat/commit/52010b2eac166c78cd02906302bdc16a48e6403d
