Failed building wheel for blspy on raspberry pi about chia-blockchain HOT 10 CLOSED

It looks like libsodium23 did not get installed.

Did you run:
sudo apt-get install build-essential git cmake libgmp3-dev --no-install-recommends sudo apt-get install python3-dev python3-venv --no-install-recommends
?

If so, then I'll update the README to include a separate install for libsodium23.

I'm getting the same issue on Ubuntu 19.

Yes, installed the apt packages.

When I tried to install the libsodium23 package, apt says it is already the newest version

Libsodium is not the issue, the BLS library should work whether or not sodium or gmp are installed or not.

The issue seems to be the architecture word size. bls-signatures library sets the default to 64 bit. If you are not using a 64 bit architecture I assume it will not work. Can either of you confirm that you are on a 32 bit system?

apparently all raspberry pi's are 32bit

64-bit, it seems.

Oh, by the way... I'm not on a Raspberry. I'm on Ubuntu 19. I replied to this Issue since it was the same error message.

Raspberry Pi's are not all 32 bit. The one we test on is:

uname -a
Linux ubuntu 5.3.0-1017-raspi2 #19-Ubuntu SMP Thu Jan 16 18:25:50 UTC 2020 aarch64 aarch64 aarch64 GNU/Linux

ok, im updating my pi to the same :) thanks for this

Raspbian can be set to a 64bit kernel though that may not be enough. 64 bit Ubuntu on Pi3/Pi4 is known to work https://github.com/Chia-Network/chia-blockchain/wiki/Raspberry-Pi
