New issue 3046: Raspberry Pi Observations - RAM and Library Checks? https://bitbucket.org/pypy/pypy/issues/3046/raspberry-pi-observations-ram-an... Alex Edwards: Hi, I’ve just been compiling PyPy pypy2.7-v7.1.1-src.zip on a Raspberry Pi ‘stretch’ - quite a slow process! :slight_smile: Thought I’d share my installation experience and niggles and hope it helps. After quite a long time, 30-60mins perhaps, it bombed out with insufficient memory. I added some more swap and its working. It could be handy to simply warn if memory less than 500MB or 1GB spare perhaps? Adding 1GB swap worked, though I didn’t try smaller amounts. Then installing again, after perhaps an hour, the build failed again because of a missing -dev library / package libbz2-dev. Then twice more on libncurses5-dev. I then found your helpful page - [http://doc.pypy.org/en/latest/build.html](http://doc.pypy.org/en/latest/build.html) - and installed all the packages I could in advance. sudo apt-get install libexpat1-dev sudo apt-get install libncurses-dev sudo apt-get install libncursesw-dev sudo apt-get install libgdbm-dev sudo apt-get install tk-dev -- installs X, so avoid if possible sudo apt-get install liblzma-dev It would have helped me a lot if these dependencies had been spotted and warned/failed sooner. Also a link to your installation page would help too, rather than failing on one package per long compile. PS - I only more recently noticed that a newer version of pypy is in Raspbian buster - I should probably have just installed that! :smiley: Cheers Alex
