ERROR_MOD_NOT_FOUND when using call_external [message #37355] Tue, 09 December 2003 01:08

I got the fftw binary from www.fftw.org and am trying to call it from IDL. I
have searched the forum and have found little info about this error.

Here is how I am calling it:

array = call_external('fftw3.dll', 'fftw_malloc', 32, /CDECL)

My path is set up so that IDL knows where the dll is. I also get the error
without /CDECL. I have also tried prepending the function name with an
undeline as someone in another post that I came across had suggested.

At this point I have no clue what to do. I don't have the means nor the
skills to recompile dlls such that they work properly with IDL. I am hoping
this works out of the box.

Any ideas?
