Issue #17792 has been updated by mame (Yusuke Endoh).


Sorry for a less informative reply, but Ruby is not yet tested well with 64 bit Raspberry Pi. I have no environment to reproduce the issue. Contribution is welcome.

I see a similar random failure on our CI (raspbian10-aarch64, still beta) but I'm unsure if it is the same issue. And I cannot log in to the machine. @znz can you check it out?

Bug #17792: make notes and make test fail with Ruby3.0.1p64 RaspberryPI 4B Ubuntu 20.10 ARM64

----------------------------------------
I am building Ruby 3.01 from sources on a RaspberryPI 4B running Ubuntu 20.10 ARM64.

This is my first day using this PI4B + Ubuntu 20.10 ARM64, and this is the first time I have attempted to build Ruby on it.
I received a few notes during compilation and one failure during testing.

Note that on the previous day, I built the same Ruby sources on the same machine running RaspberryPI OS (32-bit Debian), no problems. FYI, you can use either a 32-bit or a 64-bit OS on the RasberryPI 4B.

Anyway, here are the details of what I experienced on the PI4B using Ubuntu 20.10 ARM64:

During the make, I get a few notes:

compiling parse.c
parse.y: In function °∆node_assign°«:
parse.y:11265:1: note: parameter passing for argument of type °∆struct lex_context°« changed in GCC 9.1

      | ^~~~~~~~~~~~~
compiling proc.c

The build is successful, but when I run make test, I get one failure

I went ahead and did the make install, which succeeded.
I now have an installation of Ruby which I will be working with over the next few months to see if it works OK.

If you need more info, please let me know.
