<div>Dear members,</div><div><br></div>I used toolchain to build cp2k-8.1, the whole building process was well-off and the testing was successful. However, when I used the command like this "mpirun -n 24 cp2k.popt cp2k.inp 1>cp2k.out 2>cp2k.err", the process was stopped and the error information was<div>"cp2k.popt: error while loading shared libraries: libgfortran.so.5: cannot open shared object file: No such file or directory". Both popt and psmp version were faced to the same error information above. This libgfortran.so.5 file was found in the /lib64 directory via the "ldd cp2k.popt" command, and I tried to add this path in my bashrc with the sentence "export LD_LIBRARY_PATH=/lib64:$LD_LIBRARY_PATH" and source ~/.bashrc again but it still does not work. So how to solve this problem properly?</div><div><br></div><div>The relevant files and pictures were in the attachment including the testing summary, error information, bashrc settings, setup file. And my system was CentOS 7, the gcc, g++, gfortran were updated to 9.3.1 version.<img alt="test-summary.png" data-iml="26387254.5" width="536px" height="206px" src="cid:7e9b8ebe-b989-4e00-aaf2-546664819f8a"><img alt="bashrc.png" data-iml="26387255.200000286" width="536px" height="71px" src="cid:850728a6-7336-4f07-a3db-a2d7a5d6ea23"><img alt="popt-err.png" data-iml="26387256" width="536px" height="80px" src="cid:9e2a8f27-a5a2-4eb3-be85-d8e08b0a2a28"><img alt="psmp-err.png" data-iml="26387256.599999905" width="536px" height="79px" src="cid:9f32b9d7-a076-449b-9b04-faeaa90788f9"></div>
