CP2K binaries for 32bit Windows
CP2K is a program to perform simulations of solid state, liquid, molecular and biological systems. Cygwin-i686-gfortran.sopt is an arch file (definitions for different architectures/compilers) for building a CP2K binary with Cygwin on Windows PC.
For detail to use Cygwin-i686-gfortran.sopt, please see How to Compile and Install CP2K on Windows with Cygwin. Instead of building binaries by yourself, you can use precompiled binaries in the Releases.
