Platform:

iMac Late 2015 4 GHz Quad-Core intel Core i7, macOS Big Sur 11.2.3

Problems occur when compiling bigdecimail.c.

I cannot reproduce the error. re-install XcodeTools might solve your problem.

see ​https://github.com/rbenv/ruby-build/issues/1505#issuecomment-752274233

$ sudo rm -rf /Library/Developer/CommandLineTools
$ xcode-select --install
$ sudo xcode-select -s /Library/Developer/CommandLineTools

[josephsacco]

Uninstalling and reinstalling CommandLineTools [yet again... :-)] did not solve the problem:

I checked the tool path:

cavandish:~ jsacco$ xcode-select -p
/Library/Developer/CommandLineTools

All seems well. So what is the cause of the problem?

Examining the code in bigdecimal.h, I see that the (re)declaration of each of those errant functions is protected by an #ifndef MACRO directive. For example:

#ifndef HAVE_RB_ARRAY_CONST_PTR
static inline const VALUE *
rb_array_const_ptr(VALUE a)
{
    return FIX_CONST_VALUE_PTR((RBASIC(a)->flags & RARRAY_EMBED_FLAG) ?
    RARRAY(a)->as.ary : RARRAY(a)->as.heap.ptr);
}
#endif

Searching the source code, I do not see where HAVE_RB_ARRAY_CONST_PTR is previously set.

cavandish:ruby-3.0.0 jsacco$ grep -R HAVE_RB_ARRAY_CONST_PTR *
ext/bigdecimal/bigdecimal.h:#ifndef HAVE_RB_ARRAY_CONST_PTR

So something is amiss...

I updated port:ruby30 to 3.0.1.

If this problem was not solved, could you attach the following log files?

• config.log
• mkmf.log of ext/bigdecimal

% sudo port selfupdate
% sudo port clean ruby30
% sudo port -nsf build ruby30
% cd `port work ruby30`
% ls -l ruby-3.0.1/config.log

Thanks Joseph,

I reproduced this error when I activated port:binutils. I'll fix the Portfile of ruby30.

As an ad-hoc solution, you can install ruby30 with temporally deactivation of port:binutils.

% sudo port deactivate binutils
% sudo port clean ruby30
% sudo port install ruby30
% sudo port activate binutils

[josephsacco]

You are welcome... :-)

I can confirm that your suggested work-around succeeds.

The reactivation of binutils issues an "interesting" warning:

cavandish:~ jsacco$ sudo port activate binutils
--->  Computing dependencies for binutils
--->  Activating binutils @2.36.1_0
--->  Cleaning binutils
--->  Some of the ports you installed have notes:
  binutils has the following notes:
    Having binutils installed will cause some other ports to fail to build.
    Consider uninstalling binutils.
