Currently, it is masked for further testing. It works fine for me and passes all the tests, but please give it a spin an report back. Thanks, Markus ediap@users.sourceforge.net 2006-02-23 09:46:43 0000 I can confirm that fftw 3.1 works OK on x86 (Intel Pentium-M) architecture. Here are the flags I used for compilation: [ Found these USE variables for sci-libs/fftw-3.1 ] U I - - 3dnow : Adds support for 3dnow multimedia processor instructions - - altivec : Adds support for optimizations for G4 and G5/ppc970 processors + + sse : fast floating point optimization for PentiumIII+ class chips + + sse2 : faster floating point optimization for SSE2 capable chips BR, /ediap markusle@gentoo.org 2006-02-26 13:55:58 0000 Hi Adam, Thank you very much for reporting back. After some further testing I'll hopefully be able to unmask fftw-3.1 soon. Thanks, Markus
