Re: [AMBER] Building Amber 14 for Intel PHIs

Hi David,

Who did you get this version of AMBER from? - There are separate branches
for Xeon Phi development so I would be surprised if you have the 'correct'
development version. Can I suggest trying the original AMBER 14 release
version with the various update patches applied. There will be an
additional update for Xeon Phi coming in about a month but that is not
complete yet so a development version of that will not work right now.

Also note that this error is coming from the linker and has nothing to do
with AMBER - looks like a problem with GNU binutils to me. I would suggest
updating your system fully (yum update) and then also making sure you have
the very latest version of the Intel Composer Suite.

All the best
