Dear Community,<div><br /></div><div>I'm trying to calculate the band structure of a cubic bulk material using the HSE06 hybrid functional with CP2K 2025.2.</div><div><br /></div><div>With relaxed structure, I first performed a PBE energy calculation with k-point sampling and obtained a wavefunction file named ENERGY-PBE.kp. I then attempted to use this file as the initial wavefunction guess for the HSE06 calculation.</div><div><br /></div><div>However, when the HSE06 calculation reads the ENERGY-PBE.kp file and tries to run, CP2K terminates with the following error:</div><div><br /></div><div>"This CP2K executable has not been linked against the required library libint."</div><div><br /></div><div>The complete output is attached as cp2k_out.txt.</div><div><br /></div><div>Interestingly, when I run the same HSE06 calculation without reading the PBE wavefunction file, the calculation starts successfully. However, convergence is much slower and the calculation requires substantially more computational time.</div><div><br /></div><div>I contacted the staff responsible for the HPC system, but they were unable to determine the cause of the error. They provided details of the installed CP2K and Libint configurations, which are attached as "cp2k_2025.2_libint.txt". Based on the available information, it seems that the hfx related libint appears to absent (Tho the HSE06 calculation without reading PBE.kp file can still run).</div><div><br /></div><div>Can you please advise whether this problem may be related to the CP2K compilation, the compatibility of the PBE wavefunction file with the HSE06 calculation, or a particular input setting? Is there anything wrong during the installation? Did they miss some files that were supposed to be downloaded? If yes, is there any way for them to get the files?</div><div><br /></div><div>Much appreciate for any guidance on this.</div><div><br /></div><div>Kind regards,</div><div>Weiyi </div>
<p></p>
