waf checks for wrong versions

[Aljosha Papsch]

waf checks and fails for vala-1.0, which is non-existent as we are far from that version and gdl-1.0 but gdl-3.0 (2.91.92) is current version. See attachment for ./waf configure output. Symlinking the .pc files only helps at configure stage. building will fail then with error:
error: Package `vala-1.0' not found in specified Vala API directories or GObject-Introspection GIR directories

Possible solution: adjust mandatory versions in waf's configuration

I tried to configure with the current gtk+-3.0 branch. waf still fails, this time only at gdl-1.0 check. When symlinking gdl-3.0.pc to gdl-1.0.pc and trying to ./waf, the build will still fail with error message:
error: Package `libvala-0.12' not found in specified Vala API directories or GObject-Introspection GIR directories
./waf configure found libvala-0.12 though and it is installed beside version 0.14.

I added blank lines in attachment for better view.

This bug affects me too on Ubuntu 12.04.1 64-bit.

This bug affects me too. I run Fedora 20. In order to be able to configure, I changed the wscript to include the right libraries.

The lines I changed were:

 53 conf.check_cfg (package='libvala-0.22', uselib_store='VALA', atleast_version='0.22.0', args='--cflags --libs', mandatory=True)
 54 conf.check_cfg (package='gdl-3.0', uselib_store='GDL', atleast_version='3.00', args='--cflags --libs', mandatory=True)

This worked correctly.

I should have done the build: it crashes because the wscript_build of libvalide specifies libvala-012. Changing that to libvala-022
and gdk-1 to gdk-3 solved the waf problems, but caused a lot of compiling problems involving gdk and gtk.

In short, this problem needs some more investigation.
