I want to use downloaded libfftw3-3.dll in my vc6 project.

I created libfftw3-3.lib file by:
lib /machine:i386 /def:libfftw3-3.def

and added libfftw3-3.lib to be linked to my project.
(
Or I hope, I have done so:
I added 'libfftw3-3.lib' to 'Object/library modules' in
Project->Settings->Link folder and Set the path of the library in
Tools->Options->directories..
Linker also asks for the 'libfftw3-3.lib' if I delete it. That's why I think
it uses this file for linking
)

But building still fails:
gargle.obj : error LNK2001: unresolved external symbol __imp__fftw_free@4
gargle.obj : error LNK2001: unresolved external symbol
__imp__fftw_destroy_plan@4
gargle.obj : error LNK2001: unresolved external symbol __imp__fftw_execute@4
gargle.obj : error LNK2001: unresolved external symbol
__imp__fftw_plan_dft_r2c_1d@16
gargle.obj : error LNK2001: unresolved external symbol __imp__fftw_malloc@4

This is ar some 'pieces' of 'dumpbin /exports libfftw3-3.lib':
File Type: LIBRARY
    Exports
      ordinal    name
   _fftw_destroy_plan
   _fftw_execute
   _fftw_free

What am I doing wrong????

really lost.
