Compiling gnome-sudoku on Ubuntu 16.04 (standard unity desktop)

[Igor Lopez <igor lopez bredband net>]

Hi,

I have fetched the source (latest commit 283f24cd2f4fa754d7b7ab7baf533ad7e4281462) and am trying to build it.

Running: 

 $ ./autogen.sh --prefix=`pwd`/install

in the gnome-sudoku folder gives me this:

 .

 .

 checking pkg-config is at least version 0.16... yes

 ./configure: line 16245: APPSTREAM_XML: command not found

 checking for GNOME_SUDOKU... no

 configure: error: Package requirements (

   glib-2.0 >= 2.40.0

   gio-2.0 >= 2.40.0

   gtk+-3.0 >= 3.19.0

   gee-0.8

 ) were not met:

 No package 'gtk+-3.0' found

 Consider adjusting the PKG_CONFIG_PATH environment variable if you

 installed software in a non-standard prefix.

 Alternatively, you may set the environment variables GNOME_SUDOKU_CFLAGS

 and GNOME_SUDOKU_LIBS to avoid the need to call pkg-config.

 See the pkg-config man page for more details.

Checking for gtk I get this:

 $ dpkg --list gtk*

 ii  gtk2-engines-murrine:amd64        0.98.2-0ubuntu2.1        amd64                   cairo-based gtk+-2.0 theme engine

 un  gtk2.0-binver-2.10.0                   <none>                         <none>                  (description missing)

 un  gtk3-binver-3.0.0                        <none>                         <none>                  (description missing)

 un  gtk3-engines-oxygen                  <none>                         <none>                  (description missing)

I can't say I know what pulled in the gtk2 component and I am not a stranger adding more packages as long it does not break current.

The gnome-sudoku version bundled in the distribution is of version 3.18.2 and is running under unity.

I just want to see if I can make some modifications (and maybe learning some vala at the same time)

How should I proceed to be able to build the application(before modifying it)?
