There is no real (technical) reason why you cannot build on x86_64 hardware. I never ever built anything on ARM directly using cross compilers on an x86_64 host is orders of magnitude faster so I saw no reason to attempt to build on ARM. The ARM hardware I worked with had only 128MB of RAM and a 400Mhz CPU but the same should apply to modern ARM platforms too (i.e building on x86_64 is just the saner way). -- devel mailing list devel@xxxxxxxxxxxxxxxxxxxxxxx https://admin.fedoraproject.org/mailman/listinfo/devel
