Dear QE users, In compiling QE in order to know whether the external fftw library included in Intel MKL (version 13) is used, instead of internal fftw is used, I changed the name of the file "fftw.c" in the directory "clib" into different name. The compilation failed with following message:
make[1]: *** No rule to make target `fftw.c', needed by `fft_stick.o'. Stop. make[1]: Leaving directory `/home6/ttvo/espresso-4.3.2_test/clib' make: *** [libs] Error 2 This may mean that the the code failed to find the external library and continued to use the internal one. I have one question to confirm what I understand, and I appreciate if you could help. if the external library is used, does the internal "fftw.c" is still called by some subroutine in the code? Thank you, Trinh Vo JPL/CalTech Research and Technology Staff -------------- next part -------------- An HTML attachment was scrubbed...
