[PATCH v6 1/6] meson: Allow user to override setup command options

[PATCH v6 1/6] meson: Allow user to override setup command options

[Tom Hochstein]

The user cannot override the setup command options --cross-file and
--native-file because the meson-wrapper places these options on the
command line after the user options. This problem was noticed when
trying to build with an SDK using a custom cross-file.

[PATCH v6 2/6] toolchain-scripts: Add Meson settings for Yocto build SDK

[Tom Hochstein]

The Meson settings for the standalone SDK also need to be available for
the Yocto build SDK, a.k.a. meta-ide-support.

[PATCH v6 3/6] toolchain-scripts: Export meson settings for SDK builds

[Tom Hochstein]

Create a new set of exports for the Meson `host_machine` cross settings.
This allows the target cross file to be created correctly from
meson.cross.template and aligns with meson.bbclass.

Note, one might think that HOST_OS and HOST_ARCH would be appropriate as
inputs here, aligning nicely with the Meson naming. That turns out to be
incorrect since the script is generated in a native/nativesdk build with
HOST_OS and HOST_ARCH set for the "build machine", not the "host
machine", using the Meson terminology. See
https://mesonbuild.com/Cross-compilation.html.

[PATCH v6 4/6] meson: Fix host_machine setting for native cross-file

[Tom Hochstein]

For native and nativesdk, the meson cross-file settings for
`host_machine` are incorrectly set for the build machine, not the
"machine on which the compiled binary will run". See
https://mesonbuild.com/Cross-compilation.html.

[PATCH v6 5/6] oeqa/sdk/meson: improve test to validate host/build target assignments

[Tom Hochstein]

From: Ross Burton <ross.burton@arm.com>

Use 'meson introspect' to dump JSON describing the build configuration
and validate that the build and host architectures are correctly set in
the meson.cross file.

Also instead of calling ninja directly, call the relevant meson commands.

Hi Tom,

Thanks for the new version, but we still have a failure. Same error I
believe:

Traceback (most recent call last):
  File "/srv/pokybuild/yocto-worker/genericarm64/build/meta/lib/oeqa/sdk/cases/meson.py", line 52, in test_epoxy

Skip the test in this case.

I think this may not be quite right as I saw:

Thanks, Richard. I'm able to reproduce this. It's specific to 
meta-ide-support.

The setup looks fine:

$ meson setup --warnlevel 1 -Degl=no -Dglx=no -Dx11=false build
meson-wrapper: Running meson with setup options: " 
--cross-file=.../poky/build/tmp/sysroots/x86_64/usr/share/meson/arm-poky-linux-gnueabi-meson.cross 
--native-file=.../poky/build/tmp/sysroots/x86_64/usr/share/meson/meson.native 
"
The Meson build system
Version: 1.7.2
...

The KeyError appears because the build machine data is empty:

$ meson introspect -i --compilers build

         "c": {

         }
     },
     "build": {}
}

I don't understand why. The meson.native file looks the same as for the 
standalone SDK case, and the meson machine data seems fine.

$ meson introspect -i --machines build/

     "host": {
         "system": "linux",

         "is_64_bit": false,
         "exe_suffix": "",

         "is_64_bit": true,
         "exe_suffix": "",
