#18550: fftw-3[-single] 3.2.1 : should not have --enable-fma for Intel builds ----------------------------------+----------------------------------------- Reporter: eborisch@… | Owner: macports-tickets@… Type: defect | Status: new Priority: Normal | Milestone: Port Bugs Component: ports | Version: 1.7.0 Keywords: fftw-3 fftw-3-single | Port: fftw-3 ----------------------------------+----------------------------------------- Both the fftw-3 and fftw-3-single ports have --enable-fma in their configure.args. These should be removed, as they are incorrect for Intel builds, and replaced with the appropriate platform-specific args. Suggested args:[[BR]] PPC: --enable-fma --enable-altivec[[BR]] Intel: --enable-sse OR --enable-sse2 (for fftw-3-single, and fftw-3, respectively) It might also be nice to add '-O3 -fomit-frame-pointer -fstrict-aliasing' to the configure.cflags-append -- most folks using FFTW are going for speed; might as well build for it. (These flags were found on the FFTW benchmark site: [http://www.fftw.org/speed/Pentium4-3.06GHz/] and [http://www.fftw.org/speed/G5-2GHz-macosx/]) -- Ticket URL: <http://trac.macports.org/ticket/18550> MacPorts <http://www.macports.org/> Ports system for Mac OS
