C++ library mismatch

[Iris]

I used MadGraph as usual and it suddenly failed to create root file.
The followings showed up on the shell.

fatal error: file
      '/Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/../include/c++/v1/__config'
      modified since it was first processed
Warning in cling::IncrementalParser::CheckABICompatibility():
  Possible C++ standard library mismatch, compiled with _LIBCPP_VERSION v1101 but extraction of runtime standard library version failed.

Any clues?

Hi,

This really does not looks like related to any MadGraph file.
Did you update xcode recently? Looks like your version of xcode in not compatible anymore with your root version.

I’m sorry but I doubt that I can help you on this

Cheers,

Olivier
