For official submission to mainline Buildroot:

This new series has the following upgrades:
  - It now works on all architectures supported by qemu-host.
  - Gstreamer1 can now compile gir files properly. (for real this time).
  - General makefile cleanups.
  - New patches that make cross-compiling a bit nicer (thanks, yocto!)
  - Removed a patch that was yocto specific and not needed with buildroot.
  - Added a PKG_GIR_EXTRA_LIBS variable in pkg-autotools.mk

What I could use help with:

- Package updates: I will get around to updating python-gobject as it's needed
  for GStreamer-python (the entire reason I started this venture)
- Comments on the patches themselves would also be appreciated!.
- More testing!

Thanks!

Adam Duskett

Add a new variable in qemu.mk: QEMU_USER_OPTS. When qemu-$(ARCH) is
called, some architectures require a -cpu flag to be passed, or else a
segfault may occure when building introspection files.
For PowerPC, many of these cpu's need a specific CPU flag to be passed
via the command line.

To get GStreamer ready for introspection, we must first explicitly
disable gstreamer1, plugins base and plugins bad from using introspection.
If not, adding the gobject-introspection will result in these packages
failing to build because setting the _GIR_EXTRA_LIBS_PATH variable is required.

The other gstreamer1 packages do not require setting the _GIR_EXTRA_LIBS_PATH
variable.

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 eight 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.

8) Add Float128 patch: Newer versions of the GNU C library started
    exposing `_Float128` in the headers, which means we need to add
    this type to the known tokens, to avoid warnings.

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- at HOST_QEMU_ARCH@ @HOST_QEMU_CPU_TUNE@
    in favor of @QEMU_USER@ (Thanks Yann)

+Date: Mon, 19 Oct 2015 18:29:21 +0300
+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.

+scanner: Add _Float128
+
+The ISO/IEC TS 18661-3:2015 standard added new floating point types to
+the C standard.
+
+Newer versions of the GNU C library started exposing `_Float128` in the
+headers, which means we need to add this type to the known tokens, to
+avoid warnings.

+	  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.

+${my_name} tries to mimick the behavior of a real native ldd, but can be
+used in a cross-development environment. Here is how it differs from a
+real native ldd:
+
+If the CT_XLDD_VERBOSE variable is set and non-empty, then ${my_name} will
+print a lot of debug messages, explaining how it builds the library
+search path, and how each library was found and why.
+
+The LD_LIBRARY_PATH variable is not used, as it can not reliably be
+guessed except@runtime, and we can't run.
+
+${my_name} does not scan /etc/ld.so.cache, but instead uses /etc/ld.so.conf
+(it understands the include directives therein for libces that have that).
+
+${my_name} also interprets (tries to!) the RPATH/RUNPATH records found in
+the dynamic ELF section. Such paths are searched for only relative to
+the specified root, not from the sysroot (see below). Also, those paths
+are searched for not only for the file they appear in, but also for its
+dependencies.
+
+${my_name} will search the directory specified with --root for libraries
+to resolve the NEEDED tags. If --root is not set, then ${my_name} will
+use the value in the environment variable \${CT_XLDD_ROOT}. If neither
+is set, then this is an error.
+
+If NEEDED libraries can't be found in the specified root directory, then
+${my_name} will also look in the sysroot of the toolchain to see if it
+can find them.
+
+For NEEDED libraries that were found, the output will look like:
+        libneeded.so => /path/to/libneeded.so (0xloadaddr)
+
+and for those that were not found, the output will look like:
+        libneeded.so not found
+
+The paths are relative to the specified root directory, or to the sysroot
+(eg. /lib/libneeded.so, /usr/lib/libneeded.so, and so on...).
+
+The expected load address 'loadaddr' is a faked address to match the output
+of the real ldd, but has no actual meaning (set to some constants for now,
+0x8badf00d for libraries from the sysroot, 0xdeadc0de for those found via
+the RPATH/RUNPATH records, and 0xdeadbeef for others).

Now that there is support for gobject-introspection, we can add the appropriate
configuration options to support compiling against gobject-introspection.

In addition: gst1-plugins-base requires a patch to drop a incorrect reference
to sdp when compiling the rtsp gir file.

Changes v1 -> v4:
  - Add patch to series.

Changes v4 -> v5:
  - Changed --enable-introspection=yes to --enable-introspection (Yann)
  - Changed += GIR_EXTRA_LIBS_PATH="$(@D)/gst/.libs:$(@D)/libs/gst/base/.libs"
    to GSTREAMER1_GIR_EXTRA_LIBS_PATH=$(@D)/gst/.libs:$(@D)/libs/gst/base/.libs

What did you meant with "PACKAGE_ARCH"? I guess it's a leftover from the
previous iteration, right?

Just removing it looks like the correct phrasing to me, right?

Adma, All,

On 2018-03-18 15:01 -0400, Adam Duskett spake thusly:

If there are other packages that may support GIR, we can add that option
later on as we discover them.

Suggest updating those patches to all have links to upstream
submissions as the string provided with the "Upstream: " comment in
the description of the patch.

Should the pkg-autotools.mk changes for this option, be a separate
patch added before the others that use it?

Wondering if anyone has a concern with the wrappers being relocatable?
 The use case would be a developer builds their own library and wants
to generate GIR using the SDK.

I believe it would just require the wrappers to use full paths so that
the support/misc/relocate-sdk.sh as part of "make sdk" can fixup the
wrappers.   However, the sdk make target and the relocate-sdk.sh would
need to be updated to handle fixing up the staging directory paths...
Unsure if the staging fixup would be a good thing though, as other
files in that folder may not like that (nothing else really should
have absolute paths, right? so maybe it's transparent).  Another
approach would be to make the wrappers relative pathed but that gets
tricky with HOST_DIR and STAGING_DIR having the option of being custom
locations and not in the same output folder.

Does the GI_SCANNER_DISABLE_CACHE stick if a SDK was relocated?
Assuming it's a default which is captured as part of the tool build.

 Only HOST_DIR has the option of being in a custom location. STAGING_DIR is
always $(HOST_DIR)/$(GNU_TARGET_NAME)/sysroot.

 And in fact, relocate-sdk.sh is already going through STAGING_DIR: it does a
grep -r on HOST_DIR so it *will* also recurse into STAGING_DIR.

 Arnout
