[Pw_forum] PWscf compilation error

[Jerry]

I found this on the quantum espresso website:

If you get error messages at the loading phase that look like file XYZ.o: unknown / not recognized/ invalid / wrong file type / file format / module version, one of the following things have happened:
you have leftover object files from a compilation with another compiler: run make clean and recompile.
make did not stop at the first compilation error (it may happen in some software configurations). Remove the file *.o that triggers the error message, recompile, look for a compilation error.
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.

Hi all,
I am trying to install QE 5.4.0 on centos, configure is successful but I am getting the following error in make. Could you please help me resolve the error.
