cp2k 2.6.0 compilation on cygwin

[brhr]

Hello,

 

The problem was settled.

I had used the archiver of Lhaplus which is very popular in Japan to unpack 
cp2k-2.6.0.tar.bz2.

 
Additional directories named PaxHeaders.XXXX and files were generated in 
the unpacked cp2k-2.6.0 directory and its subdirectories, these files 
seemed to be responsible for the compilation failure of cp2k 2.6.0. 

 

Instead of using Lhaplus, I used Cygwin command to unpack tar.bz2.

tar -xvf cp2k-2.6.0.tar.bz2

 

I made a definition file which named Cygwin-i686-gfortran-noflag.sopt as 
follows,

 

CC       = cc

CPP     = 

FC       = gfortran

LD       = gfortran

AR       = ar -r

CPPFLAGS = 

DFLAGS   = -D__FFTSG

FCFLAGS  = -O2 -ffast-math -funroll-loops -ftree-vectorize -ffree-form 
$(DFLAGS) 

LDFLAGS  = $(FCFLAGS) 

LIBS     =  -llapack -lblas

 

,which is almost identical to Cygwin-i686-gfortran.sopt in cp2k-2.5.1/arch 
except absence of -D__FORTRAN and -march=native flags.

-D__FORTRAN may be unnecessary (as I read by an another thread in this 
group).

I removed -march=native to run the cp2k.sopt on Windows PC which Cygwin is 
not installed. 

After I did the following command operation, “make 
ARCH=Cygwin-i686-gfortran-noflag VERSION=sopt”, cp2k.sopt and other sopts 
were generated in exe directory. The cp2k.sopt seems to work fine.
