The hypervisor build system requires `python`. To avoid putting too
much (confusing) information in README, mandate availability of
`python`.

Since we're not in a release crunch any more, it seems like updating ./configure to look for ""python3", "python2", and "python" (probably in that order) would be a better solution here. -George _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel

No, it is not about tools build. Hypervisor build depends on `python` but we don't want it to depend on configure. See "Hypervisor build can't work without `python` (Was: Re: Xen commit 9b0bc91b3 possibly removed too much info from README)" Wei. > > -George _______________________________________________ Xen-devel mailing list Xen-devel@lists.xenproject.org https://lists.xenproject.org/mailman/listinfo/xen-devel

What about specifying PYTHON= on the make cmdline? I don't mean to say the set of workarounds needs to be exhaustive here, but perhaps add at least "e.g." if there are other options as well?

Xen's build system is strange in that make A=B is not the same as A=B make . In practice this has bitten a few people in the past. That's why I opted to not mention that variant. But since you ask, I can add it to next version.
