[Pw_forum] compilation issue, QE 5.3.0

[Giovanni Cantele]

Thanks for your response. Is there any way in which to make Intel MKL working automatically after configure?

Indeed, after adding -I/opt/intel/mkl/include/fftw/ to IFLAGS, the compilation goes on but then stops at the point where the executable pw.x
should be created, with the error:
/opt/intel/mkl/interfaces/fftw3xf/libfftw3xf_intel.a(fftw_version.o):(.rodata+0x0): multiple definition of `fftw_version'
../../FFTXlib/libqefft.a(fft_stick.o):(.data+0x430): first defined here
ld: Warning: size of symbol `fftw_version' changed from 8 in ../../FFTXlib/libqefft.a(fft_stick.o) to 25 in /opt/intel/mkl/interfaces/fftw3xf/libfftw3xf_intel.a(fftw_version.o)


I never found this kind of errors with previous QE releases.

Giovanni
