Re: [AMBER] Testing C++11 support: Not present

Hi,

Apple is notorious for breaking development environments with OS
upgrades, so this is unfortunate but unsurprising. We've had to jump
through many hoops just to keep Amber compiling properly on OSX. I'm
not sure which if any devs currently have Mojave (I certainly don't),
so I don't really have a timeline for when this might get fixed.

However, regarding the 'C++11 not present' issue - this isn't really
an error, more a warning to let you know that the compiler doesn't
seem to support the C++11 stuff that the PME library (helPME) needs.
If you don't need PME support in cpptraj you can ignore this since no
other components of cpptraj care about it.

Using Homebrew and trying to use the parameters set by “brew” i am compiling using the Mac clang compiler and the “brew” gfortran compiler. This has worked well for a good long while now.
