Adam Duskett July 29, 2018, 7:19 p.m.
GObject introspection is a middleware layer between C
libraries (using GObject) and language bindings. The C library
can be scanned at compile time and generate a metadata file,
in addition to the actual native C library. Then at runtime,
language bindings can read this metadata and automatically
provide bindings to call into the C library.

There's an XML format called GIR used by GObject-Introspection.
The purpose of it is to provide a standard structure to access the
complete available API that a library or other unit of code exports.
It is meant to be language agnostic using namespaces to separate
core, language or library specific functionality.

Cross-compiling gobject-introspection is not an easy task. The main
issue is that in the process of creating the XML files,
gobject-introspection must first run and scan the binary, which, if the
binary is cross-compiled, would not typically be possible from the host
system.

Because of this limitation, several wrappers are used to call instead
first out qemu which will then run the native scanner to create the
binaries.

There are seven total patches and four different wrapper files needed
to successfully cross-compile and run this package, many of them are
from open-embedded, but two of them are of my own doing.

1) Revert a previous, incomplete attempt at adding cross-compiling
    support.

2) Add support for the various wrappers. (See patch for details.)

3) Add an option to use a binary wrapper; this patch will force
   giscanner to use a wrapper executable to run binaries it's producing,
   instead of attempting to run them from the host.

4) Add an option to use an LDD wrapper, again, useful for
    cross-compiled environments.

5) Overwrite python includes during the initial configure stage.

6) Add a --lib-dirs-envar option to pass to giscanner.
   (See patch for details.)

7) Add rpath-links to ccompiler: when passing the
    PACKAGE_GIR_EXTRA_LIBS_PATH to the ccompiler.py script,
    ccompiler.py needs to add -Wl,-rpath-link to the environment for the
    package to correctly link against the passed on paths.

Changes v1 -> v2:
  - Fixed wrappers
  - Added 0007-giscanner-add-a-lib-dirs-envvar-option.patch
  - Added 0008-add-Float128.patch

Changes v2 -> v3:
  - Removed Linux kernel dependency (baruch)
  - Changed $(LINUX_VERSION) to $(BR2_TOOLCHAIN_HEADERS_AT_LEAST) (baruch)
  - Changed @LINUX_VERSION@ in g-ir-scanner-qemuwrapper.in to
    @TOOLCHAIN_HEADERS_VERSION@ to match the above variable change.
  - Added BR2_PACKAGE_GOBJECT_INTROSPECTION_ARCH_SUPPORTS_TARGET in Config.in
    with only BR2_arm selected for now.
  - Removed BR2_PACKAGE_HOST_QEMU_ARCH_SUPPORTS in favor of the above change.
  - Added two new lines in the base Makefile which removes any remaining .gir
    or .rnc files from the target filing system, as these are not needed for
    runtime, only compile time.

Changes v3 -> v4:
  - Removed RFC tag.
  - Added 0007-Add-rpath-links-to-ccompiler.patch
  - Removed config-paths-with-PKG_CONFIG_SYSROOT_DIR-.patch as it is not
    Yocto specific.
  - Added the _GIR_EXTRA_LIBS_PATH to pkg-autotools.mk. This allows package
    specific Gir libraries to be passed on to g-ir-scanner-qemuwrapper.
  - Fixed a typo in g-ir-scanner-qemuwrapper.in.
  - Remove BR2_PACKAGE_GOBJECT_INTROSPECTION_ARCH_SUPPORTS_TARGET in favor of
    BR2_PACKAGE_HOST_QEMU_ARCH_SUPPORTS

Changes v4 -> v5:
  - Added a more detailed commit message (Yann)
  - Removed  $HOST_DIR/bin/qemu-@HOST_QEMU_ARCH@ @HOST_QEMU_CPU_TUNE@
    in favor of @QEMU_USER@ (Thanks Yann)

Changes v5 -> v6:
  - Update gobject-introspection to 1.56.1
  - Remove upstreamed 0008-add-Float128.patch

Changes v6 -> v7:
  - Remove the cross-ldd script in favor of the prelink-cross package.
  - Install the ldd and qemu wrappers in a post patch hook seperate of
    the other wrappers.
  - Set --enable-introspection-data in the configure options.

Changes v7 -> v8:
  - Add "select BR2_PACKAGE_HOST_PRELINK_CROSS" to Config.in

+Subject: [PATCH] configure.ac: add host-gi, gi-cross-wrapper, gi-ldd-wrapper and introspection-data options
+
+With the first option, gobject-introspection tools (g-ir-doc-tool and g-ir-scanner)
+that are already installed in the host system will be used for building the source tree.
+
+With the second option, g-ir-scanner will be instructed to use an executable
+wrapper to run binaries it's producing, and g-ir-compiler will be run
+through the same wrapper (host system's g-ir-compiler cannot be used because
+it's producing architecture-specific output).
+
+With the third option, giscanner will be instructed to use a special ldd
+command instead of system's ldd (which does not work when the binary to inspect
+is compiled for a different architecture).
+
+With the fourth option, it is possible to disable building of introspection data
+(.gir and .typelib files), which may be difficult or impossible in cross-compilation
+environments, because of lack of emulation (or native hardware) for the target architecture
+on which the target binaries can be run.
+
+These options are useful when cross-compiling for a different target architecture.

+
+With this option, giscanner will use a wrapper executable to run
+binaries it's producing, instead of running them directly. This
+is useful when binaries are cross-compiled and cannot be run directly,
+but they can be run using for example QEMU emulation.

+Subject: [PATCH] giscanner: add a --lib-dirs-envvar option
+
+By default LD_LIBRARY_PATH is set to the list of target library paths;
+this breaks down in cross-compilation environment, as we need to run a
+native emulation wrapper rather than the target binary itself. This patch
+allows exporting those paths to a different environment variable
+which can be picked up and used by the wrapper.
