[CP2K-user] [CP2K:11149] Re: van der Waals regtests fail on Intel KNL, and build glitches

[Ronald Cohen]

This shows clearly that the file cannot be called fypped:

cp qs_basis_gradient.f90 t.fypped
rcohen at tomcat3:~/CP2K/cp2k/src$ gcc -E -cpp t.fypped
gcc: warning: t.fypped: linker input file unused because linking not done
rcohen at tomcat3:~/CP2K/cp2k/src$ cp t.fypped t.f
rcohen at tomcat3:~/CP2K/cp2k/src$ gcc -E -cpp t.f | head
# 1 "t.f"
# 1 "<built-in>"
# 1 "<command-line>"
# 1 "t.f"
