[Buildroot] [PATCH v15 5/5] package/gobject-introspection: new package

Tue Feb 4 21:39:56 UTC 2020
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 one of them is of my own doing.
1) Revert a previous, incomplete attempt at adding cross-compiling support.
2) Add support for cross compiling with meson.
3) Disable tests.
4) 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.
5) Add an option to use an LDD wrapper, again, useful for cross-compiled
environments.
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) Ignore error return codes from ldd-wrapper because prelink-rtld returns 127
when it can't find a library, which will break subprocess.check_output().

Changes v14 -> v15:
- Fixed number of patches in commit message. (Arnout)
- Fixed license information (Adam)
- Sorted dependencies (Arnout)
- Removed redundant comment (Arnout)
- Reordered host and target macros (Arnout)
- Moved wrappers and wrapper installation logic to the host dir. (Arnout)
- Combined the find functions in the target_finalize_hooks. (Arnout)
Changes v13 -> v14:
- Bump to version 1.62.0
Changes v10 -> v11:
- reorder config.in entries: arch deps first, then toolchain deps
and order packages deps alphabetically (Yann)
- drop dependency on threads, wchar, and !static: it's implicit from
glibc (Yann)
- Bump to version 1.60.2
- Switched to a meson build system as autotools is no longer supported with
gobject-introspection 1.60.x.
- Removed the following patches that are no longer needed:
- 0002-configure.ac-add-host-gi-gi-cross-wrapper-gi-ldd-wra.patch
- 0005-user-PYTHON_CONFIG-to-find-includes.patch
- 0008-fix-gobject-pc.file.patch
- Add the following patches:
- 0002-add-cross-compilation-support-to-meson.patch
- 0003-meson.build-disable-tests-when-cross-compiling.patch
- 0008-ignore-error-return-codes-from-ldd-wrapper.patch
Changes v9 -> v10:
- Makefile cleanup
- Fix license syntax (Thomas)
- Add libffi as a mandatory dependency (Thomas)
- remove --disalbe-static (Thomas)
- add --with-cairo if the cairo package is selected (Thomas)
- Change PYTHON_INCLUDES to PYTHON_CONFIG in gobject-introspection.mk
(Thomas)
- Use | for all sed functions (Thomas)
- Remove GOBJECT_INTROSPECTION_WRAPPERS (Thomas)
- Add GOBJECT_INTROSPECTION_REMOVE_DEVELOPMENT_FILES target finalize
hook. (Thomas)
- Use $(dirname $0) in wrappers instead of $STAGING_DIR (Thomas)
- Remove _GIR_EXTRA_LIBS_PATH in pkg-autotools.mk in favor of a
seperate patch. (Thomas)
Changes v8 -> v9:
- Create the $(STAGING_DIR)/usr/lib/gio/modules-dummy directory in the
GOBJECT_INTROSPECTION_POST_PATCH_HOOKS to prevent qemu from
segfaulting when g-ir-scanner-qemuwrapper is ran.
- Remove the $(STAGING_DIR) prefix from gobject-introspection-1.0.pc
to prevent pkg-config from appending a second staging_dir to the path
of the g-ir-compiler. This prevents packages such a gstreamer1 from
trying to call $(STAGING_DIR)/$(STAGING_DIR)/usr/bin/g-ir-compiler,
which will break the build.
Changes v7 -> v8:
- Add "select BR2_PACKAGE_HOST_PRELINK_CROSS" to Config.in
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 v5 -> v6:
- Update gobject-introspection to 1.56.1
- Remove upstreamed 0008-add-Float128.patch
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)
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 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 or runtime, only compile time.
Changes v1 -> v2:
- Fixed wrappers
- Added 0007-giscanner-add-a-lib-dirs-envvar-option.patch
- Added 0008-add-Float128.patch

+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.
