(at least is working here on the G4) vapier@gentoo.org 2006-04-09 10:12:16 0000 Mark pointed out the bug here: configure:21661: checking altivec.h usability configure:21673: powerpc-unknown-linux-gnu-gcc -c -O2 -mtune=powerpc -pipe conftest.c >&5 In file included from conftest.c:75: /usr/lib/gcc/powerpc-unknown-linux-gnu/4.1.0/include/altivec.h:37:2: error: #error Use the "-maltivec" flag to enable PowerPC AltiVec support configure:21679: $? = 1 and indeed, if i change config.h to define HAVE_ALTIVEC_H, the compile works so not a gcc bug ;) vapier@gentoo.org 2006-04-09 14:19:13 0000 Created an attachment (id=84322) fftw-altivec-headers.patch this patch should fix the issue (it did for me) ... it should also be sent upstream ... markusle@gentoo.org 2006-04-10 06:33:51 0000 Hi SpanKY, Thank you very much for the patch! Does it by any chance also fix the altivec issues with gcc-3.4 (the ebuild disables altivec for gcc-3.4 at the moment)? Thanks, Markus vapier@gentoo.org 2006-04-10 15:24:45 0000 it should markusle@gentoo.org 2006-04-10 22:07:54 0000 Hi SpanKY, I've just added the patch to the fftw-3.1.1.ebuild and will send it upstream as well. Thanks again! best, Markus vapier@gentoo.org 2006-04-10 22:21:10 0000 you need to run autoconf in src_unpack after applying the patch ... either that or create a patch against configure ... markusle@gentoo.org 2006-04-10 23:10:04 0000 Thanks for pointing that out and for your patience :( I added an eautoconf and I better get some sleep now.
