[OE-core][PATCH 0/2] Add support to compile source for multilib in the eSDK

[Jagadeesh K]

* Install multilib toolchain in the eSDK if multilib configuration is
enabled during the eSDK build.
* Search multilib manifest files to populate multilib packages such as
lib32-gcc-runtime during the eSDK installation.

[OE-core][PATCH 1/2] meta-extsdk-toolchain: Install multilib toolchain files in the eSDK if multilib is enabled

[Jagadeesh K]

1. Ship multilib virtual/cross-cc, virtual/compilerlibs, and virtual/libc
packages in the eSDK if it is created with multilib configuration. These
packages are required to compile source for multilib using the eSDK.

2. Include multilib tune configuration directory in SPDX_MULTILIB_SSTATE_ARCHS
to search SPDX document as meta-extsdk-toolchain is dependent on multilib recipes.

[OE-core][PATCH 2/2] staging: parse multilib sstate manifest files to install multilib packages in the eSDK

[Jagadeesh K]

Since the multilib-DEFAULTTUNE is not part of <pkgarch> of
staging_populate_sysroot_dir function, the SSTATE_MANFILEPREFIX files
of multilib packages are not parsed and due to this multilib package
files are not populated in the <eSDK_install_dir>/tmp/sysroots during
the installation of the eSDK. Hence, the eSDK sysroots lacks header files
required to compile source for multilib.
For example:
The header file bits/c++config.h given by lib32-gcc-runtime recipe,
is not populated in the <eSDK_install_directory>/tmp/sysroots
by the staging_populate_sysroot_dir function as <pkgarch> list does not
contains multilib-DEFAULTTUNE (i.e 'x86' in case of qemux86-64).

This change adds multilib-DEFAULTTUNE to <pkgarch> list and
thereby parsing multilib SSTATE_MANFILEPREFIX files and populating
multilib package files during the eSDK installation.

Hi Jagadeesh,

Thanks for your patch.

It looks like this is failing to build with "world" target:

ERROR: meta-extsdk-toolchain-1.0-r0 do_create_recipe_spdx: Failure expanding variable SPDX_MULTILIB_SSTATE_ARCHS, expression was ${@all_multilib_tune_values(d, 'SSTATE_ARCHS')} which triggered exception NameError: name 'all_multilib_tune_values' is not defined
...

Can you have a look at the issue?

Thanks,
Mathieu

Yes, I will look into the build failure.

I have submitted updated patches (v2) to fix the above errors.
The functions from utils.bbclass have been moved to utils.py, hence
reference of multilib_tune_values() should be replaced with oe.utils.all_multilib_tune_values().

Sorry, I could not catch this error as I was at a older code base.

Regards,
Jagadeesh
