failed to configure with --static-link

Trying to build statically for mac os, fails with the following errors:

CMake Deprecation Warning at CMakeLists.txt:299 (cmake_policy):
  The OLD behavior for policy CMP0023 will be removed from a future version

  The cmake-policies(7) manual explains that the OLD behaviors of all
  policies are deprecated and that a policy should be set to OLD only under
  specific short-term circumstances.  Projects should be ported to the NEW
  behavior and not rely on setting a policy to OLD.

Any ideas?

So I think this problem isn't related to static linking for you, as the errors say:

  LLVM requires C++11 support but the '-std=c++11' flag isn't supported.

Earlier output says:

-- The CXX compiler identification is AppleClang 10.0.1.10010046

I've tried locally with Xcode 11, my c++ --version says this:

~/hermes $ c++ --version
Apple clang version 11.0.0 (clang-1100.0.33.8)
Target: x86_64-apple-darwin19.0.0
Thread model: posix

Can you re-try with Xcode 11? You can download that from Apple's developer website, and you can
use sudo xcode-select -s /Applications/Xcode_version.app/ to switch which Xcode is available on
the command line.

Also, if that succeeds, I've found that locally using --static-link will fail on MacOS with the following message:

[207/318] Linking CXX executable bin/hermesc
FAILED: bin/hermesc
...
ld: library not found for -lcrt0.o
clang: error: linker command failed with exit code 1 (use -v to see invocation)

According to a Stack Overflow post, MacOS makes it pretty hard to request
a full static link.

We don't support full static linking on MacOS, see

hermes/CMakeLists.txt

Line 84 in ef513ad

"Link Hermes statically. May only work on GNU/Linux.")

. However, the binary we produce on MacOS only depends on system libraries, so a static link should not be needed.
