come on and don't tell me 99% of i686 users have machines older than 10 years https://en.wikipedia.org/wiki/SSE3 because "ntel introduced SSE3 in early 2004 with the Prescott revision of their Pentium 4 CPU"
those machines would not be able to run a recent Fedora due all the bloat introduced over the years - try a system update with 512 MB and shake your hands with the OOM-killer
with that argumentation Fedora would drop i686 at allNo. darktable handles the situation on sse3-less CPUs gracefully at run-time. The actually problem is darktable wanting to be compiled with -msse3, which means being compiled with a Fedora incompatible instruction set, on both i386 and x86_64.
Fedora incompatible?many software including the kernel has binary code for AVX and even AVX2 and is using CPU runtime detection - using SSE3 instructions in a software is not bound to compiler flags and when a upstream developer don't care about 11 year old hardware you have to suck taht downstrem
well, i don't have any non x86_64 machien but the argumentation is bogusYou are right, these days in professional PC-usage, i686ers likely are rare and hard to find. But in personal (private) PC-usage, the situation is different. There, 5/6-year old 32bit PCs are still wide spread and will be supported by Windows for many years. Also consider, people are using Linux on such machines to extend these machines life time.
there is nothing like a 5 year old 32bit-only machine, but that's not the point, i explained the OP and package maintainer that he is talking nonsense in the context of "99% of all 32bit CPUs don't support SSE3" and have no idea why you need to contradict here
Feel free to drop the i386, if you want drop the end-user/desktop market and to leave this market to Ubuntu, Debian and other distributions
see above
