Currently, the process_pkgconfig() only handles the "Requires" key
field from the .pc file and ignores the "Requires.private" field while
generating the dev dependency chain. This results in a broken dependency
list and requires the installation of recommended packages to resolve
the build dependencies when using the dev IPKs. This increases the
hard disk space usage and download time and installs many unnecessary
packages as part of the recommendations.
This patch ensures that the "Requires.private" field is also considered
when creating the dependency list for the dev IPKs. With this, the dev
IPK will have the proper dependencies listed, eliminating the need to
install recommended packages to resolve the build time dependencies.
Example: usr/lib/pkgconfig/libical.pc
----------
Libs: -L${libdir} -lical -licalss -licalvcal
Libs.private: -lpthread
Requires.private: icu-i18n
----------
Depends field generated for libical-dev
Depends: glib-2.0-dev, libical (= 3.0.7-r0)
------------
When trying to resolve the build time dependency with libical
package using “-dev” ipk generated, it will throw the below error.
-----------
Package icu-i18n was not found in the pkg-config search path.
Perhaps you should add the directory containing `icu-i18n.pc'
to the PKG_CONFIG_PATH environment variable
Package 'icu-i18n', required by 'libical', not found
-----------
This patch will fix the broken dependency list.

Poky
Poky is an integration of various components to form a pre-packaged build system and development environment which is used as a development and validation tool by the Yocto Project. It features support for building customised embedded style device images and custom containers. There are reference demo images ranging from X11/GTK+ to Weston, commandline and more. The system supports cross-architecture application development using QEMU emulation and a standalone toolchain and SDK suitable for IDE integration.
Additional information on the specifics of hardware that Poky supports is available in README.hardware. Further hardware support can easily be added in the form of BSP layers which extend the systems capabilities in a modular way. Many layers are available and can be found through the layer index.
As an integration layer Poky consists of several upstream projects such as BitBake, OpenEmbedded-Core, Yocto documentation, the 'meta-yocto' layer which has configuration and hardware support components. These components are all part of the Yocto Project and OpenEmbedded ecosystems.
The Yocto Project has extensive documentation about the system including a reference manual which can be found at https://docs.yoctoproject.org/
OpenEmbedded is the build architecture used by Poky and the Yocto project. For information about OpenEmbedded, see the OpenEmbedded website.

Where to Send Patches
As Poky is an integration repository (built using a tool called combo-layer), patches against the various components should be sent to their respective upstreams:
OpenEmbedded-Core (files in meta/, meta-selftest/, meta-skeleton/, scripts/):
- Git repository: https://git.openembedded.org/openembedded-core/
- Mailing list: openembedded-core@lists.openembedded.org
BitBake (files in bitbake/):
- Git repository: https://git.openembedded.org/bitbake/
- Mailing list: bitbake-devel@lists.openembedded.org
Documentation (files in documentation/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/yocto-docs/
- Mailing list: docs@lists.yoctoproject.org
meta-yocto (files in meta-poky/, meta-yocto-bsp/):
- Git repository: https://git.yoctoproject.org/cgit/cgit.cgi/meta-yocto
- Mailing list: poky@lists.yoctoproject.org
If in doubt, check the openembedded-core git repository for the content you intend to modify as most files are from there unless clearly one of the above categories. Before sending, be sure the patches apply cleanly to the current git repository branch in question.
