title: fftw in Visual Studio?
body: <p>I'm trying to link my project with fftw and so far, I've gotten it to compile, but not link. As the site said, I generated all the .lib files (even though I'm only using double precision), and copied them to <code>C:\Program Files\Microsoft Visual Studio 9.0\VC\lib</code>, the .h file to <code>C:\Program Files\Microsoft Visual Studio 9.0\VC\include</code> and the .dll to <code>C:\windows\system32</code>.</p>
  
  <p>I've copied the tutorial program, and the exact error I am getting is:</p>
  
  <pre><code>1&gt;hw10.obj : error LNK2019: unresolved external symbol __imp__fftw_free referenced in function "bool __cdecl test(void)" (?test@@YA_NXZ)
  1&gt;hw10.obj : error LNK2019: unresolved external symbol __imp__fftw_destroy_plan referenced in function "bool __cdecl test(void)" (?test@@YA_NXZ)
  1&gt;hw10.obj : error LNK2019: unresolved external symbol __imp__fftw_execute referenced in function "bool __cdecl test(void)" (?test@@YA_NXZ)

  1&gt;hw10.obj : error LNK2019: unresolved external symbol __imp__fftw_malloc referenced in function "bool __cdecl test(void)" (?test@@YA_NXZ)
  </code></pre>
  
  <p>So, what could be wrong with my project setup? Thanks!</p>
