It appears that python-blosc is supposed to work on the pi, but on my rpi2 running arch, after cloning the git repo and running python setup.py install, I'm getting the output below. Anyone else have any luck?

  • It looks like you are building a package which does not support the Pi. Second don't link to the error include it in your answer, where did you get the package? Did it claim to support the arm architecture of the Pi. Is there a precompiled binary available? what is the bigger picture - there may be alternatives available? Are you following a tutorial? If so which tutorial? Sep 21 '15 at 15:10
  • @SteveRobillard Edited to link release notes explicitly stating it should work on rpi. Also added elaboration of my install process and output. Sep 21 '15 at 16:21
  • How do you know this is supposed to work on the Pi? What version are you building? Sep 21 '15 at 16:56
  • In the "Changes from 1.3.6 to 1.4.0" release note I linked, it explicitly states that it installs on the Pi and passes all tests. I'm building from the latest code in the git repo, but see no subsequent commits or release notes suggesting that support for the Pi was intentionally removed. Sep 21 '15 at 17:18
  • it appears from the above output "creating build/temp.linux-armv7l-3.4/blosc" that you are ecompiling 1.3.4. as you pointed out support for the arm is only available in 1.4.0 and above. Sep 21 '15 at 17:51
