[fedora-arm] Questions for building RPMs for armel and armfp
Hi Folks,
Apologies in advance if this is a FAQ. But I can't seem to find concrete
answers to what seem like relatively common questions.
The problem we have is the need to build current Fedora SRPMs for armel and possibly
armhf. We have an embedded product using an ARM926EJ-S core and another using a
Cortex-A9. Constraints dictate the RPMs to be built under in-house control and we're
trying to understand the path of least resistance and greatest reusability as Fedora
ARM moves forward.
- So the first fundamental question is to what degree current Fedora SRPM content
supports cross platform builds on an x86_64 host? This would be our first
preference though it isn't clear to what extent the core project infrastructure
supports this, if at all.
- Beyond cross builds infrastructure support is the question of what degree SRPMs
themselves support cross platform builds. This being an embedded platform, runtime
needs are minimal (no graphics, no heavy scripting languages, applications, etc..
So we're not faced with building a conventional workstation class RPM userland
content.
- My impression however is while some off-shoot efforts of Fedora ARM do build cross
platform, the main project release builds native on an ARM host. Moreover on bare
metal
ARM vs. an ARM VM for efficiency. Is this correct? If so what are our options for
a build host Fedora ARM distribution at the present? Eg is a 32-bit ARM distro
install required or will a 64-bit ARM install (eg: v8) be able to build SRPMs for
armel and armhf? The latter seems to be approaching a cross platform build, depending
upon what is available in a 64-bit Fedora ARM install now, and in the near future.
That's probably enough for now, answers to the above should help us quickly narrow
down the problem space we're grappling with.
Many thanks,
