[Server-devel] armv7hl vs armv7l

[George Hunt]

I want to add my repo's url to /etc/yum.repos.d/ and have "yum install"
find my rpms.

Maybe my problem is that I really don't understand the difference between
in yum's use of $ARCH and $BASEARCH for arm.

After a little reflection, I can just do "trial and error". If my rpms are
not found, I can just change the path from ../rpms/armv7hl/... to
../rpms/armv7l/.. and recreate the repo xml files.

I read on the fedora wiki that userland armv7hl and armv7l complied
programs don't mix.  But your assurance that the XO is really armv7hl is
what I couldn't find easily on the web.

Thanks again,

George
