[ruby-core:109936] [Ruby master Bug#18912] Build failure with Xcode 14 and macOS 13 (Ventura) Beta

Issue #18912 has been updated by hsbt (Hiroshi SHIBATA).

Subject changed from Build failure with macOS 13 (Ventura) Beta to Build failure with Xcode 14 and macOS 13 (Ventura) Beta

Xcode 14 has been released. The all stable versions of Ruby couldn't build with Xcode 14.

We fixed this issue at Ruby 2.7-3.1 and master branch. But the stable versions are not released yet.

I strongly recommend to not upgrade Xcode 14 and its toolchains for macOS users. If you already update Xcode 14, you remove them with

```
sudo rm -rf /Library/Developer/CommandLineTools
```

and install Xcode 13.x or toolchains from https://developer.apple.com/download/all

----------------------------------------
Today, I tried to build ruby master with macOS 13 (Ventura) Beta. It breaks the build status caused by Xcode 14 beta changes.

TL;DR: We should add `--without=+,bigdecimal --enable-shared` to the `configure` option.

1. Build failed without `--enable-shared`.

I build ruby master without `--enable-shared` option. I got the following error.

```
(snip)
linking shared-object -test-/arith_seq/extract.bundle
Undefined symbols for architecture arm64:
  "_rb_arithmetic_sequence_extract", referenced from:
      _arith_seq_s_extract in extract.o
  "_rb_ary_new_capa", referenced from:
      _arith_seq_s_extract in extract.o
  "_rb_ary_store", referenced from:
      _arith_seq_s_extract in extract.o
  "_rb_define_singleton_method", referenced from:
      _Init_extract in extract.o
  "_rb_path2class", referenced from:
      _Init_extract in extract.o
ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
```

@katei says this error affects with `-undefined dynamic_lookup` flags.

2. Build error with bigdecimal

With `--enabled-shared` resolved the first error. But I got the another build failure.

```
compiling bigdecimal.c
In file included from bigdecimal.c:13:
In file included from ./bigdecimal.h:14:
./missing.h:127:1: error: static declaration of 'rb_rational_num' follows non-static declaration
rb_rational_num(VALUE rat)
^
../.././include/ruby/internal/intern/rational.h:128:7: note: previous declaration is here
VALUE rb_rational_num(VALUE rat);
      ^
In file included from bigdecimal.c:13:
In file included from ./bigdecimal.h:14:
(snip)
```

It's affected with `static inline` declaration in missing.h of bigdecimal.

3. test failure with mjit

I could build with `--with-out-ext=+,bigdecimal --enable-share` option. But I also got the test failure with mjit.

```
[215/402] TestMJIT#test_lambda_longjmp = 0.19 s
192) Failure:
TestMJIT#test_lambda_longjmp [/Users/hsbt/Documents/github.com/ruby/ruby/test/ruby/test_mjit.rb:1045]:
Expected 1 times of JIT success, but succeeded 0 times.

script:
"""

fib = lambda do |x|
  return x if x == 0 || x == 1
  fib.call(x-1) + fib.call(x-2)
end
print fib.call(5)

"""


stderr:
"""
Undefined symbols for architecture arm64:
  "_mjit_call_p", referenced from:
      __mjit0 in _ruby_mjit_p39885u0-643ab5.o
      _vm_sendish in _ruby_mjit_p39885u0-643ab5.o
```

I already shared this to @k0kubun .

macOS 13 beta is still development status. I will track this until the official release date.
