Minimal list to build all cpu architectures?

We have s script to build our feed. We want to build for all cpu architectures. The docker is just for all targets, but not every target has a new cpu architecture. Is there somewhere a minimal list for targets that we have to use to build for all cpu architectures?

Probably the 30 architectures that packages are built for in the packages buildbot.

That is the cpu architecture, but I'm searching for target list, since the sdk is target based and not cpu architecture based. :wink:

You can use that list to lookup the SDKs used.

Just navigate to a build of each of those, and check from the SDK step, which SDK is used. Requires some manual work but is doable.

( I do not remember having seen a collected list anywhere)

Within each cpu architecture there is the target and subtarget for each device listed.

Thanks I now have some list, with some missing targets.

Well, for those architectures you cannot find any target there are either no devices supported using it and/or the list is incomplete/outdated. For e. g. mipsel_mips32r2 is indicated it is not supported anymore (since 2017). But there are still devices listed.

The list is (I don't really know) autogenerated from the list of devices supported. But the device list is including a lot of very old devices (which are not supported anymore by newer builds) also.

You have to decide what you want to support and choose accordingly. Nobody is using powerpc_440 nor i386_i486 nowdays. Or better I would not support it if I were you. :wink:


You could use that what buildbot is making as a model.

I don't know what creterias buildbot is doing it builds. But it is not focussing on generic only (e. g. rampis). It looks more like "mainstream"?
