[Insight-users] Insight-users Digest Questions - Problems Building FFTW From Review

Tue Nov 22 00:12:51 EST 2011

Hi Antonio Gómez Barquero,

Just an update. I completed your steps 1-6 and the project built for the
first time but now when I go to debug a window pops up and has the
following message

`The program can't start because libfftw3-3.dll is missing from your
computer. Try reinstalling the program to fix this problem.'

I did not touch libfftw3-3.dll so I am not sure what happened. Did you ever
get this error?

Thanks for your help again,

Calvin

ps Sorry for sending twice but I forgot to include insight-users at itk.org
