Introspection data generation error in evince (autotools vs meson)

Gtk+ - Apps Dev mailing list
Hello,

I have recently started porting evince to meson. The port is almost
complete but I have an issue with the generation of introspection data of
one of its libraries, `libevview3`, which I haven't been able to figure out
due to my limited introspection knowledge.

The introspection build parameters are as follows in the autotools'
Makefile[0]:

```
INTROSPECTION_COMPILER_ARGS = --includedir=$(top_builddir)/libdocument

EvinceView-$(EV_API_VERSION).gir: libevview3.la
EvinceView_@EV_API_VERSION_U@_gir_FILES = \
    $(INST_H_SRC_FILES) \
    $(INST_H_BUILT_FILES)   \
     $(filter %.c,$(libevview3_la_SOURCES))
EvinceView_@EV_API_VERSION_U@_gir_INCLUDES = GLib-2.0 GObject-2.0 Gio-2.0
Gdk-3.0 GdkPixbuf-2.0 Gtk-3.0
EvinceView_@EV_API_VERSION_U@_gir_LIBS = libevview3.la
$(top_builddir)/libdocument/libevdocument3.la
EvinceView_@EV_API_VERSION_U@_gir_CFLAGS = \
    -I$(top_srcdir)         \
    -I$(top_builddir)       \
    -I$(top_srcdir)/libdocument \
    -I$(top_builddir)/libdocument   \
    -DEVINCE_COMPILATION
EvinceView_@EV_API_VERSION_U@_gir_EXPORT_PACKAGES =
evince-view-$(EV_API_VERSION)
EvinceView_@EV_API_VERSION_U@_gir_SCANNERFLAGS = \
    --add-include-path=$(top_builddir)/libdocument  \

--include-uninstalled=$(top_builddir)/libdocument/EvinceDocument-$(EV_API_VERSION).gir
\
    --identifier-prefix=Ev              \
    --symbol-prefix=ev
INTROSPECTION_GIRS = EvinceView-$(EV_API_VERSION).gir

girdir = $(datadir)/gir-1.0
gir_DATA = EvinceView-$(EV_API_VERSION).gir

typelibsdir = $(libdir)/girepository-1.0
typelibs_DATA = EvinceView-$(EV_API_VERSION).typelib
```

These produces the following command lines:

```

g-ir-scanner: EvinceView: warning: 2 warnings suppressed (use --warn-all to

```

This command creates the `EvinceView-3.0.gir` file properly. I tried to
replicate this on meson by using the same parameters[1]:

```
  incs = [
    'Gdk-3.0',
    'GdkPixbuf-2.0',
    'Gio-2.0',
    'GLib-2.0',
    'GObject-2.0',
    'Gtk-3.0',
    libevdocument_gir[0],
  ]

  gnome.generate_gir(
    [libevview, libevdocument],
    sources: sources + headers + [enum_sources[1]],
    includes: incs,
    nsversion: ev_api_version,
    namespace: 'EvinceView',
    identifier_prefix: ev_code_prefix,
    symbol_prefix: ev_code_prefix.to_lower(),
    export_packages: 'evince-view-' + ev_api_version,
    extra_args: '-DEVINCE_COMPILATION',
    install: true,
  )
```

These produces the following command line:

```

--extra-library=synctex --extra-library=z
```

However, it seems that the important parameters are in place, in the same
way as autotools does.

libs: `--library evview3 --library evdocument3`
namespace: `--namespace=EvinceView`
namespace version: `--nsversion=3.0`
girs: `--output EvinceView-3.0.gir`
includes: `--include=Gdk-3.0 --include=GdkPixbuf-2.0 --include=Gio-2.0
--include=GLib-2.0 --include=GObject-2.0 --include=Gtk-3.0`
scanner flags: `--add-include-path=./libdocument/
--include-uninstalled=libdocument/EvinceDocument-3.0.gir
--identifier-prefix=Ev --symbol-prefix=ev`
export packages: `--pkg-export=evince-view-3.0`
cflags: `-DEVINCE_COMPILATION`

The contents of the 'filelist' file 'EvinceView_3.0_gir_filelist', contains
the same list of files as those used by autotools:

```
../libview/ev-annotation-window.c
../libview/ev-document-model.c
../libview/ev-form-field-accessible.c
../libview/ev-image-accessible.c
../libview/ev-jobs.c
../libview/ev-job-scheduler.c
../libview/ev-link-accessible.c
../libview/ev-page-accessible.c
../libview/ev-page-cache.c
../libview/ev-pixbuf-cache.c
../libview/ev-print-operation.c
../libview/ev-stock-icons.c
../libview/ev-timeline.c
../libview/ev-transition-animation.c
../libview/ev-view.c
../libview/ev-view-accessible.c
../libview/ev-view-cursor.c
../libview/ev-view-presentation.c
../libview/ev-media-player.c
../libview/ev-document-model.h
../libview/ev-jobs.h
../libview/ev-job-scheduler.h
../libview/ev-print-operation.h
../libview/ev-stock-icons.h
../libview/ev-view.h
../libview/ev-view-presentation.h
/home/imartinez/Development/gnome/evince/_build/libview/ev-view-type-builtins.h
```

As you can also see, meson doesn't use libtool to assist in the creation of
the introspection data. It also appends some libraries/dependencies used in
the generation of the `libevview3` by using the `--extra-libraries` option.

However, meson is not able to generate the introspection data due to the
following error:

```
libview/ev-document-model.h:33:
libview/ev-document-model.h:57: Fatal: EvinceView: Namespace conflict for
'document_model_get_type'
libview/ev-document-model.h:57: Fatal: EvinceView: Namespace conflict for
'document_model_get_type'
```

I'm not able to figure out what is the reason behind the `Namespace
conflict`. When using autotools, the information from `DocumentModel` is
properly included in the introspection data in the following way:

```
  <namespace name="EvinceView"
             version="3.0"
             shared-library="libevview3.so.3,libevdocument3.so.4"
             c:identifier-prefixes="Ev"
             c:symbol-prefixes="ev">
    <class name="DocumentModel"
           c:symbol-prefix="document_model"
           c:type="EvDocumentModel"
           parent="GObject.Object"
           glib:type-name="EvDocumentModel"
           glib:get-type="ev_document_model_get_type"
           glib:type-struct="DocumentModelClass">
```

Does anyone have any idea about what might be happening?

Thanks,

Best regards,

Re: Introspection data generation error in evince (autotools vs meson)

Gtk+ - Apps Dev mailing list
Just as a follow up to this for the archives, since it has been fixed in
Evince[0]:

 - the issue is caused by a double declaration of `GType
ev_document_model_get_type (void)`—one by the G_DECLARE_FINAL_TYPE at line
33, and one explicit at line 57. This confuses the g-ir-scanner parser, and
would be nice to track it down a bit further
 - next time, you probably want to use gir-devel-list for this kind of
issues, not gtk-app-devel-list

Ciao,
 Emmanuele.
