Preface:

For the several days straight I have taken it upon myself to try to get
gobject-introspection integrated with BuildRoot. This is no light undertaking.

Through multiple discussions with Yann, Thomas, and Arnout, staring at
the bitbake recipe, I have managed to cobble together what I believe a fairly
decent starting point.

However; I am at the point where I need help to cross the finish line and
to put this beast to bed, and that's where I am going to rely on the rest
of the maintainers to help me.

Thomas, Arnout, Yanni, and anybody else who dare look upon the horrors of
gobject-introspection, I caution you, this is for people with a strong iron
will and a hearty constitution.

Why do you ask?  What could possibly be so bad about this library?
A multitude of things. However; let me just paste a quote from a developer:

"Basically, we produce a binary that contains an array of ints with 
constant expression initialisers (sizeof, struct offsets, etc).
We put magic values on either side of that array and then we scan
the resulting compiler output for those magic values in order to
discover the values of the expressions we put in."

To top it all off:  This program requires host-qemu to run. There isn't
a good way for us to bypass it either. This means that several wrappers
are needed that call host-qemu-$(arch) and then the real program that
reads the binary and produces a .gir and a .typelib file.


If it's so bad, why does BuildRoot need it?
Good question! Because several prominent programs and libraries depend
on gobject-introspection to compile. This also means that buildroot is
stuck a very very old version of python-gobject (2.28.6) because anything
newer requires this library to build.

This also means that a very prominent and juicy library that is sorely
lacking from BuildRoot is missing. gst1-python. This would be a very
very nice library to have.


WHAT WORKS:

Currently, this patch series does the following:
- builds the latest host-gobject-introspection.
- Installs the wrapper programs.
- builds the latest target gobject-introspection
- After the target system is built, removes all the .gir files from
  the target directory.
  (.gir files are for development, typelib is for runtime.)


WHAT DOESNT WORK:

This is where I am hung up and need help!

Anybody wanting to help, I urge you to do the following:
- Apply the patch series
- Build gobject-introspection
- build gstreamer

Gstreamer will now fail to build!
Why? Gstreamer looks for an introspection library during the configure
stage, and if it finds it, attempts to use it.
Because some library paths not being making it to the introspection
compiler, it will now fail to build with linking errors! Oh no!

In Yocto, you can call out:
export GIR_EXTRA_LIBS_PATH="path" 
(see meta/recipes-multimedia/gstreamer/gstreamer1.0.inc for an example)
in the recipe file, which will be then get passed to g-ir-scanner-qemuwrapper,
which will then set the environment variable LD_LIBRARY_PATH to the value of
GIR_EXTRA_LIBS_PATH, whcih will then call g-ir-scanner, which will then
call the functions in the script entitled "ccompiler.py" in the host directory.
which will then resolve the library paths properly based off of the
LD_LIBRARY_PATH variable. It's a very easy and clean solution to the problem.

However, this isn't possible with BuildRoot because a script called from
a GNU Makefile can't change the parent environment, and so the build
will fail miserably.

(Granted we could just disable introspection for gstreamer, but then it
be possible to later add gst1-python)

I hope there is a clean solution to this problem that will make it easier
to add the library paths to programs in the future that isn't more patches.

I really would appreciate a good discussion on this, as what you see here
is around 40 hours of work in 3.5 days.

Thanks for the help!

Adam

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.

This is a work in progress. PLEASE read the cover letter before
responding! This is NOT COMPLETE!

+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.

+Subject: [PATCH] giscanner: add --use-binary-wrapper option
+
+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.

+${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).

 So setting

GSTREAMER_MAKE_ENV = GIR_EXTRA_LIBS_PATH="path"

doesn't work? I wonder why not...

 Arnout

It doesn't! And I could really use some help with this!

Looking into it, there are 4 recipes in Yocto that require the
GIR_EXTRA_LIBS_PATH flag.

cogl, gstreamer, gtk3, and avahi.  (gtk-doc also uses it, but we don't
build gtk-docs).

Buildroot doesn't provide Cogl, so would it be best just to provide
patches for gstreamer and avahi?
