Seems to work fine in all other contexts (including Eigen itself), but doesn't help with FFT :( On Apr 5, 2012, at 19:52, "Björn Piltz" <bjornpiltz@xxxxxxxxxxxxxx> wrote: > I think std::exp() might be a candidate. > > Try adding > namespace std { std::complex<Real> exp(const std::complex<Real>&); } > to your file to see if it's the culprit. > > Björn >
