Why? Because it is possible. And the OS Raspbian is distributed with a version of Mathematica 12.0
First attempt was building sage-8.9. Just did a 'make' after downloading. The RPi 4 showed unstable. The little computer stalled a few times. Power off and power on. After 12 hours there was a running sage. Building the docs failed consistently. I ran a few tests. Secondly I did a "MAKE='make -j4' make". After a few hick-ups I changed to 'make -j3' and got sage running, but building the docs failed on the same spot. Third was a try to build sage-9.0.beta9 with 'make -j3'. Again a few freezes, but the building of the docs succeeded! The same with sage-9.0.beta10. Testing with 'make ptestlong' lasted long. It was good my RPi 4 had active cooling with temperatures up to 75 degrees Celcius. There were 60 failures, some segmentation faults some Time Outs. Most of the errors were resolved by running a bash script to test files individually. The building of sage-9.0.rc0 ended in problems with building scipy. My idea of computers being deterministic is chocked. I started with a clean source. And to my surprise only a few hick-ups and after 'make ptestlong' 56 failed tests. Most of them were resolved. See above. As we speak now sage-9.0.rc1 is doing a 'make ptestlong'. Probably will finish in a few hours. My conclusion so far: Sage can be built on a Rarpberry Pi 4, but certainly not unattended. Most remarkable: Saved trace to /home/pi/.sage/crash_logs/crash_s8ljau3w.log ------------------------------------------------------------------------ Unhandled SIGSEGV: A segmentation fault occurred. This probably occurred because a *compiled* module has a bug in it and is not properly wrapped with sig_on(), sig_off(). Python will now terminate. ------------------------------------------------------------------------ ********************************************************************** sage -t --long --warn-long 248.7 src/sage/rings/function_field/function_field.py #
