[ruby-core:103379] [Ruby master Bug#17792] make notes and make test fail with Ruby3.0.1p64 RaspberryPI 4B Ubuntu 20.10 ARM64

Issue #17792 has been updated by hanlyusarang (Hanlyu Sarang).


Another FYI: The RaspberryPI 4B uses a microSD card (class 10) for the OS and all installed software. I was building Ruby on a 32GB version of this card. 

The I/O on a microSD card is much slower than on a 5400 RPM HD, and much, much slower than on an SSD. I know from experience that the speed difference between the microSD card and the SSD is something on the order of 10 for intensive I/O operations.

If the test routine that failed was using a timeout mechanism. then perhaps the amount of time allowed was insufficient. But when I build Ruby on the same machine and type of card using a 32-bit Debian-like OS, no test failures. So, maybe the media speed is not a factor?

----------------------------------------
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
11265 | node_assign(struct parser_params *p, NODE *lhs, NODE *rhs, struct lex_context ctxt, const YYLTYPE *loc)

      | ^~~~~~~~~~~~~
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.
