[Wien] Where is the MKL?

[Gerhard Fecher]

Libraries are named libXXXX.yy and called to link by -lXXXX.

I do not know about the NCM Version,
this type of errors may occure if something in youre setup of the compiler or libraries
is not correct. The linker may be confused if different versions are defined by ldconfig.
In that case you may need to delete the database file for the dynamical (.so) libraries
(I don't have its name on hand) and create a new one by ldconfig.

Thank you Gerhard,
    Yes, my R_LIB options are incomplete, '-pthread' is missing.
    The other comment you make is why I use '-lmkl_lapack64', it is
because it is the recommended option, but with '-lmkl_lapack' it
compiles correctly.

    What does not compile correctly is 'lapw0' in the WIENNCM package:
the 'dlu.f' program, which seems to be exactly the same as in WIEN2k
gives the following warning:

/opt/intel/mkl/9.1.023/lib/em64t/libmkl_em64t.a(_caxpy_fb.o): In
function `caxpy_':_caxpy_iface.c:(.text+0x0): definiciones múltiples de
`caxpy_'
dlu.o:dlu.f:(.text+0x662): primero se definió aquí
ld: Aviso: el tamaño del símbolo `caxpy_' cambió de 348 en dlu.o a 278
en /opt/intel/mkl/9.1.023/lib/em64t/libmkl_em64t.a(_caxpy_fb.o)

the same message shows for caxpy, cdotu, cswap, icamax, isamax, sasum,
saxpy, sdot, sscal, sswap

the compiling options are now:
   Current settings:
     O   Compiler options:        -FR -mp1 -w -prec_div -pc80 -pad -ip
-DINTEL_VML
     L   Linker Flags:            $(FOPT)
-L/opt/intel/mkl/9.1.023/lib/em64t -lpthread
     P   Preprocessor flags       '-DParallel'
     R   R_LIB (LAPACK+BLAS):     -lmkl_lapack -lmkl_em64t -lguide -lvml
-pthread
