gobject-introspection .gir search path

[Ludovic Courtès]

While trying to package librsvg, I stumbled upon this:

--8<---------------cut here---------------start------------->8---
Couldn't find include 'GdkPixbuf-2.0.gir' (search path: ['.', 'gir-1.0', '/gnu/store/xdd5ndl01700w23z206nc36nqg96z94v-gobject-introspection-1.38.0/share/gir-1.0', '/usr/share/gir-1.0', '/gnu/store/xdd5ndl01700w23z206nc36nqg96z94v-gobject-introspection-1.38.0/share/gir-1.0'])
/gnu/store/xdd5ndl01700w23z206nc36nqg96z94v-gobject-introspection-1.38.0/share/gobject-introspection-1.0/Makefile.introspection:153: recipe for target 'Rsvg-2.0.gir' failed
make[2]: *** [Rsvg-2.0.gir] Error 1
--8<---------------cut here---------------end--------------->8---

Do you remember if the gobject-introspection “scanner” had a way to
specify a search path, like an env. var.?

Otherwise, how can we make sure that the .girs of inputs are visible?

TIA.  :-)

Look at the 'gir-directory' function in guix/build/gnome.scm. It's used
in gnu/packages/{gtk,gnome}.scm and does exactly what you need.

Oh right, thanks, that does the job.

It’d be great to submit a patch upstream so that g-ir-compiler &
co. honor a GIR_PATH environment variable or similar.  That seems like
the right thing to do, and definitely helpful for us.

Since it’s written in Python, I thought perhaps you could lend a hand?

From 'man g-ir-scanner':

"The g-ir-scanner uses the XDG_DATA_DIRS variable to check for dirs, the
girs are located in XDG_DATA_DIRS/gir-1.0."

I guess you could also use that; would it solve your problem ? I think
we might be able to remove the ugly use of '--add-include-path' in
gnu/packages/{gtk,gnome}.scm if we were to use this variable.

Indeed, adding a search path specification for ‘XDG_DATA_DIRS’ in GLib
solves this problem (I’ll commit shortly.)

Since ‘XDG_DATA_DIRS’ is also used as the search path env. var. for
GLib’s schemas, it seemed best to put it in GLib rather than
gobject-introspection.

Thanks,
Ludo’.
