Description Philipp Schlesinger 2009-01-16 16:09:55 UTC

g-ir-scanner was called like that:

    /usr/bin/g-ir-scanner -v --namespace Gegl --nsversion=0.0 \
	    --add-include-path=. --add-include-path=. \
	    --include=GObject-2.0 \
	    --include=GModule-2.0 \
	    --include=Gio-2.0 \
	    --include=cairo-1.0 \
	    --include=Babl-0.0 \
	    --library=gegl-0.0 \
	    --libtool="/bin/bash ../libtool" \
	    --output Gegl-0.0.gir \
	    --pkg cairo \
	    --pkg babl \
	    --pkg gegl \
	    `pkg-config --variable=includedir gegl`/gegl-0.0/operation/*.h \
	    `pkg-config --variable=includedir gegl`/gegl-0.0/*.h

It fails:

Traceback (most recent call last):

NotImplementedError: symbol 'GeglMatrix3' of type array


Definition of GeglMatrix3:

   typedef gdouble GeglMatrix3 [3][3];

Please let me know if I should provide additional information to deal with this bug.

Best regards,

Hmm, so this is an array type that is passed by value to several functions?

http://svn.gnome.org/viewvc/gegl/trunk/gegl/gegl-matrix.h?revision=2881&view=markup

Actually I'm unsure about this in general - according to the C FAQ that it's passed by reference for a single dimension array, but not recursively:
http://c-faq.com/aryptr/aryptrparam.html
http://c-faq.com/aryptr/pass2dary.html

There are several levels here of introspection fixes:

1) Support parsing that header and don't fail, even if the resulting API description isn't usable for a binding
2) Support array types as parameters (I'm not sure we do right now)
3) Support multidimensional arrays

Bug #738186 may be of interest. Posting here for lack of a metabug for complex arrays.
