Hi Dario, Yes, when I created the packages, I decided to build using march=core2. However, this supposes that you have a processor that supports all extensions that an Intel Core2 supports, which includes SSE3. Thus, since you are an user that does not have such processor, I will see if we can build julia using march=x86-64, which is the most generic flag that will make julia works in all 64-bit processors. I am just not sure how much performance we will loose with this change. I have already branched Leap package and it is building using march=x86-64. Can you please test this package when the building process is completed? The URL is: https://build.opensuse.org/package/show/home:Ronis_BR:branches:openSUSE:Leap:42.1/julia The build for Leap 42.1 64 bits is blocked at the moment, but it should be fine soon.
