zeek: error: aligned allocation function of type 'void *(std::size_t, std::align_val_t)' is only available on macOS 10.14 or newer

I guess this will only work on extremely new systems:

OK. Sounds like we'll have to limit week to new OS versions.

[kencu (Ken)]

This is a bit interesting, actually. On 10.6.8, where we currently use libc++ from llvm 5.0, libcxx has capability far beyond what was installed on MacOSX 10.7.

Apple has not enabled any testing for the libc++ version installed; instead, it assumes that certain OS versions have certain versions of libc++. This is mostly true, of course.

However, if we ever do start upgrading libc++ on these older 10.7 to 10.12 systems, which we could do, then we would want to disable this system version testing.

There is a simple toggle to disable it in a clang header called _config, and I have disabled that OS version testing on my older systems to not artificially limit them, when the libc++ version often has all these capabilities.

[kencu (Ken)]

Ah -- it turns out they made this one more complicated, and the libc++ toggle doesn't work with this alignment operator.

They have this hardcoded into the clang driver, and can be overridden by passing a flag saying that you know you have an aligned allocator, and you want to override it.

So -- not for older systems without surgery.
