[Buildroot] [PATCH 0/4] Fix BR2_HOSTARCH_NEEDS_IA32_* autobuilder issues

[Peter Korsgaard]

Hi,

The following patch series fixes various autobuilder issues from packages
selecting BR2_HOSTARCH_NEEDS_IA32_* without ensuring hostarch is x86(-64),
breaking the build on the gcc112 ppc64le autobuilder.

[Buildroot] [PATCH 1/4] kvm-unit-test: x86-64 variant only available on x86-64 hosts

[Peter Korsgaard]

We use the host compiler for x86-64 builds, so ensure it is only available
on x86-64 hosts.

 I don't think this is correct: it will also build correctly for x86_64 if the
host is i386, because it uses -m32 (which is the reason to use the host compiler
instead of the target compiler).

 Arnout

But some parts of kvm-unit-tests presumably are 64bit when building for
x86-64, which wouldn't work when using the host compiler on a x86
system, right? I don't think x86 system compilers are 32/64bit multilib.

But I haven't actually used a x86 distribution in the last 10 years or
so, so perhaps I'm missing something?

 OK, I assumed everything was built with -m32. If some parts are indeed still
64-bit then it won't work in i386 host.

 Actually, on Debian i386 it is possible to install 64-bit multilib I think. But
obviously we can't count on that.

 BTW, what happens on x32, does anybody know that?

> But I haven't actually used a x86 distribution in the last 10 years or

 Yeah, it's pretty unlikely as well I guess.

 I'll apply this patch as well then.

 Arnout

Is x32 really used by any mainstream distro? I would guess it is as rare
as building on a !x86 machine.

How is this going to prevent other packages from depending on
host-luajit. BR2_PACKAGE_LUAJIT_ARCH_SUPPORTS is all about the target
variant of luajit, not the host variant.

Do we need a BR2_PACKAGE_HOST_LUAJIT_ARCH_SUPPORTS or something like
that ?

For example, if you enable moarvm, host-luajit will be built, but not
luajit.

Don't we have a problem here if your solution is used ?

Thanks!

Correct.

Ahh, I had missed moarvm. Moarvm seems quite special as no other
packages need host-luajit but no luajit on the target.

Looking at the upstream project, it doesn't seem to explicitly need
host-luajit, just host-lua would do. From Configure.pl:

=item --lua=path/to/lua/executable
Path to a lua executable. (Used during the build when JIT is enabled).

This configure option is even dropped in 2017.10 with the following
information in the changelog:

+ Removal of Configure.pl --lua and --has-dynasm options, compiling with these
included 3rdparty libs is now required

Where the embedded lua copy is a tweaked lua-5.1.5:

https://github.com/MoarVM/dynasm/blob/d84e11714c9460bbb032de6cb1e06c3cb1c31f07/minilua.c

And indeed, moarvm still builds if moarvm.mk is changed to pull in
host-lua and the --lua path is adjusted. Francois, is there a specific
reason you went with host-luajit over host-lua?

So I would prefer to do that change instead of adding
BR2_PACKAGE_HOST_LUAJIT_ARCH_SUPPORTS.

I'll send a patch for moarvm.

 I really don't see why this is needed. What we need is that the host and target
bitness is the same. On x86_64, we can always do this by compiling with -m32
(which is what we do in the .mk file). But I see no reason at all why building
for a 32-bit target would not be possible on ARM, MIPS or PowerPC (32-bit).

 That said, we can't easily test that and nobody cares anyway, so I've committed
with an updated commit message.

 Arnout

Correct, I opted for the simplest possible fix as building on !x86
really isn't a very realistic use case.

 Same story here: there are combinations that should work, e.g. building for
x86_64 target on an aarch64 host. However, it's equally likely to break, and the
Config.in expressions would be quite complicated to allow it. So I've applied
after extending the commit message a little.

 Arnout
