sqrt() vs sqrtf()

[GoogleCodeExporter]

Hi,

When i build svn on my 64 bits archlinux box i get this build error :

FFTSimulation.cpp: In member function ‘void 
osgOcean::FFTSimulation::Implementation::computeBaseAmplitudes()’:
FFTSimulation.cpp:266: erreur: no match for ‘operator*’ in 
‘std::complex<float>(real, imag) * 
sqrt((((double)osgOcean::FFTSimulation::Implementation::phillipsSpectrum(((
const osg::Vec2f&)((const osg::Vec2f*)(& K))))) * 5.0e-1))’
make[2]: *** [src/osgOcean/CMakeFiles/osgOcean.dir/FFTSimulation.cpp.o] 
Erreur 1
make[1]: *** [src/osgOcean/CMakeFiles/osgOcean.dir/all] Erreur 2
make: *** [all] Erreur 2

replace sqrt by sqrtf solve the issue.

Same problem here with ubuntu 9.10 64bit. The sqrtf workaround also worked for 
me.

Hi guys,

Thanks for flagging this. I've added an ifdef around that so that it uses sqrtf 
for 
cases where the FFTWF library is used and checked it into the trunk. 

Would you be so kind as to test this for me? I don't have a 64bit system.

Cheers.

Kim.

hi,

Yes, it's ok, both with FFTW and FFTWF.
i love your: typedef std::complex<fftw_data_type> complex; 

thanks.

Anto
