 ====== How to Compile and Install CP2K with PLUMED ====== ====== How to Compile and Install CP2K with PLUMED ======
  
 +CP2K supports the current (2.x) versions of PLUMED.  PLUMED 1.3 support is available in CP2K releases 2.4 up to 3.0. Please scroll down to the relevant set of instructions depending on which version you wish to use.
  
-The current svn version of cp2k is already prepared for compilation with PLUMED and contains all the relevant interface code.+To use plumed, insert the following in the FREE_ENERGY section of a cp2k input file: 
 +<code> 
 +&METADYN 
 +     USE_PLUMED .TRUE. 
 +     PLUMED_INPUT_FILE ./filename.inp 
 +&END METADYN 
 +</code>      
 + 
 +===== PLUMED 2.x ===== 
 + 
 +CP2K may be used with PLUMED version 2.x without requiring source code patches - the interface to PLUMED is already included in CP2K in version 2.7 (rev 15615 or later).  To build a version of CP2K with PLUMED 2 follow the instructions below: 
 + 
 +  * Download the PLUMED library from [[http://www.plumed.org/]], build and install following the instructions in the PLUMED documentation. 
 + 
 +  * Modify your CP2K arch file to include the following: 
 + 
 +<code> 
 +include /path/to/your/plumed2.0/installation/lib/plumed/src/lib/Plumed.inc 
 +EXTERNAL_OBJECTS=$(PLUMED_STATIC_DEPENDENCIES) 
 +</code> 
 + 
 +  * ''-D<nowiki>__</nowiki>PLUMED2'' should be added to your DFLAGS and ''-lz -ldl -lstdc++'' to your LIBS variable 
 +<note> 
 +If using OpenMPI, you will also need to add ''-lmpi_cxx -lrt'' to LIBS 
 +</note> 
 + 
 +  * It is also possible to build PLUMED as a shared library, in which case instead of using ''EXTERNAL_OBJECTS'' simply add ''-lplumed'' to the LIBS above. 
 + 
 +  * Finally, build the CP2K binaries as normal: 
 + 
 +<code> 
 +make -j ARCH=Linux-x86-64-gfortran VERSION=popt 
 +</code> 
 + 
 +===== PLUMED 1.3 =====
