Dear Edmund Formerly I had installed PWscf on CentOS and there was not any main problem. Please be sure that your gfortran works well and note that "--with-tm" option is generally only necessary if the TM headers and libraries are not in default compiler/linker search paths. I have installed the Openmpi without "--with-tm". Did you install proper libraries on your system ?
