Subject: [ruby-core:109355] [Ruby master Bug#18912] Build failure with macOS 13 (Ventura) Beta

Issue #18912 has been updated by alanwu (Alan Wu).


@hsbt Thanks for the logs. Some symbols are
indeed not found due to link errors. For example,
`rb_complex_real()` is provided but not found.

The linker error contradicts itself:

```
have_func: checking for rb_complex_real() in ruby.h... -------------------- no
...
ld: warning: ignoring file ../../libruby.3.2-static.a, building for macOS-arm64 but attempting to link with file built for macOS-arm64
```

So the error message could be better, at least.
Maybe the linker is not printing out the full
architecture stamp that it's comparing. You could
try checking `otool -hv libruby.3.2-static.a` and
comparing that with `otool -hv bigdecimal.o`.
The `cpusubtype` column might be different.
Also, maybe bigdecimal and libruby are built with
different toolchains due the way the XCode beta is
setup? I should find some time to install the beta...

Bug #18912: Build failure with macOS 13 (Ventura) Beta
https://bugs.ruby-lang.org/issues/18912#change-98499

* Author: hsbt (Hiroshi SHIBATA)
* Status: Open
* Priority: Normal
* Backport: 2.7: UNKNOWN, 3.0: UNKNOWN, 3.1: UNKNOWN
----------------------------------------
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.
