Remove the file *.o that triggers the error message, recompile, look for a compilation error.<br>If many symbols are missing in the loading phase: you did not specify the location of all needed libraries (LAPACK, BLAS, FFTW, machine-specific optimized libraries), in the needed order. If only symbols from clib/ are missing, verify that you have the correct C-to-Fortran bindings, defined in include/c_defs.h. Note that QUANTUM ESPRESSO is self-contained (with the exception of MPI libraries for parallel compilation): if system libraries are missing, the problem is in your compiler/library combination or in their usage, not in QUANTUM ESPRESSO.</div></div><div><br></div><div>Anonymous</div><div>California State University</div><div>Chemistry student</div><div><br></div><br><br><div>-------- Original message --------</div><div>From: udayagiri sai babu <udayagiri3@gmail.com> </div><div>Date:06/12/2016 9:42 PM (GMT-08:00) </div><div>To: PWSCF Forum <pw_forum@pwscf.org> </div><div>Subject: Re: [Pw_forum] PWscf compilation error </div><div><br></div><div dir="ltr"><div class="gmail_default" style="font-size:xx-large">Can somebody guide me on how to resolve the above problem.
