As of clang-11, the most current libc++ is installed tucked away in

There is both a dylib (rpathed) and a static libc++ there.
I set this up for now for people like you to use for exactly this. You
will have to force it (DYLD_LIBRARY_PATH, possibly static link it, or
some other way).
It's new. Please feel free to let me know how it works for you.
Hi again
A bit more on the specific testcases that I want to get to compile.
The first one, using C++17 over-aligned new and delete gives me
paulf> clang++-mp-11 -g cxx17_aligned_new.cpp -std=c++17 -stdlib=libc++
cxx17_aligned_new.cpp:17:24: error: aligned allocation function of type
'void *(std::size_t, std::align_val_t)' is only available on macOS 10.14
or newer
MyClass* myClass = new MyClass;
^
I get the same when adding -L /opt/local/libexec/llvm-11/lib
-Wl,-rpath,/opt/local/libexec/llvm-11/lib -nostdinc++ -I
/opt/local/libexec/llvm-11/include/c++/v1
The message seems clear enough. Is this error to be expected? Or is
there a way to get fully featured libc++ on old machines?
The second testcase uses C++14 sized delete, and I can get that to build OK.
A+
