[Buildroot] [PATCH 1/2] host-cargo: select host-rustc

[Buildroot] [PATCH 1/2] host-cargo: select host-rustc

[Fabrice Fontaine]

Buildroot documentation specifies that cargo-based package should only
depends on BR2_PACKAGE_HOST_RUSTC_ARCH_SUPPORTS and selects
BR2_PACKAGE_HOST_CARGO but this does not work as host-cargo depends on
BR2_PACKAGE_HAS_HOST_RUSTC which is selected only when host-rustc is
selected.

So instead of having to select both cargo and rustc in each cargo-based
package, replace BR2_PACKAGE_HAS_HOST_RUSTC dependency by
BR2_PACKAGE_HOST_RUSTC_ARCH_SUPPORTS and select
BR2_PACKAGE_HOST_RUSTC

+Subject: [PATCH] Add RUST_TARGET variable
+
+Add RUST_TARGET environment variable through AC_ARG_VAR to allow the
+user to override the rust target name. Indeed, using $host when
+cross-compiling is not always the good option especially when vendor
+part of target is not set to unknown but to another value such as
+buildroot.
+Indeed, in this case aarch64-buildroot-linux-gnu won't be recognised as
+a valid target by rust/cargo.

BR2_PACKAGE_GST_PLUGINS_BAD_PLUGIN_RSVG and 
BR2_PACKAGE_GST1_PLUGINS_BAD_PLUGIN_RSVG also select BR2_PACKAGE_LIBRSVG, so 
they need that dependency.

This is not needed for host packages. Listing host-cargo in <PKG>_DEPENDENCIES 
should be enough.

As I was surprised by the new rust dependency, I looked at
https://github.com/GNOME/librsvg/blob/master/COMPILING.md. Indeed, Rust
appears to be necessary.

But the other thing that came up from this reading is:

Mandatory dependencies
[...]
GObject-Introspection 0.10.8

But we don't have gobject-introspection in Buildroot, the package for
that is pending review, and it's a complicated one. How is it possible
that you built librsvg without it ? Is the documentation incorrect and
in fact it's an optional dependency ?

Yes, rust is now needed and 2.40.x won't be maintained anymore: see
https://gitlab.gnome.org/GNOME/librsvg/merge_requests/71#note_231260.

The documentation is incorrect.
configure.ac makes a call to GOBJECT_INTROSPECTION_CHECK and not
GOBJECT_INTROSPECTION_REQUIRE.
So except, if we set --enable-introspection, build won't fail without
gobject-introspection.
gobject-instropection is only needed for vala bindings, see:
https://github.com/GNOME/librsvg/blob/f17210327623f59d4b1fbe
c538850b145f2fc069/m4/vapigen.m4.
This is the same behavior in 2.4.20.
Nevertheless, I will send you a v2 to take into account Baruch's review.

[Buildroot] [PATCH 1/2] host-cargo: select host-rustc

What "does not work" exactly ?

Yes, you end up with host-rust being built as a dependency of
host-cargo, while BR2_PACKAGE_HOST_RUST is not enabled.

But for host packages, we currently don't enforce that their
Config.in.host option is enabled when the package is built.

So, which problem have you encountered ?

I agree that your patch makes sense (it's better to have the
Config.in.host option enabled when the corresponding host package is
going to be built), but I don't see where the *problem* is, so I'd like
to understand before applying.

Thanks!

I got the following warning when I selected librsvg without this patch
because I added a "select BR2_PACKAGE_HOST_CARGO" in librsvg/Config.in as
specified in
https://buildroot.org/downloads/manual/manual.html#_integration_of_cargo_based_packages
:
warning: (BR2_PACKAGE_LIBRSVG) selects BR2_PACKAGE_HOST_CARGO which has
unmet direct dependencies (BR2_PACKAGE_HAS_HOST_RUSTC)

But thanks to Baruch review of my second patch, I understand that it is not
needed to add this select.
However, I think that documentation should be updated to remove this
select, I will send a patch to update
./docs/manual/adding-packages-cargo.txt if it's ok with you.
