I'm still having trouble installing G::O::I-0.020 I get ffi errors as below.

I must be missing an environment variable or something like that.

Thanks,

For the building of the test libraries to succeed (in the 'perl Makefile.PL' step) you need to set the GI_TYPELIB_PATH environment variable to point to the location of the typelib files:

set GI_TYPELIB_PATH=C:\usr\local\lib\girepository-1.0

I think that libffi-6.lib should define those undefined references. Though, for some reason, I also had to include libffi-6 from my Gtk-3 binaries - and my build links to C:/Gtk+3.6.1/lib/libffi.a ... not to C:/usr/local/libffi-6.lib

If you run 'dmake -v' we'll be able to see exactly which libraries it's trying to link to.

I've found a problem for us wrt Gtk3. That module has Cairo::GObject as a pre-requisite ... and I haven't been able to build that pre-requisite module in such a way that it's compatible with G::O::I.
The blocker is that the Cairo module (which is a prereq for Cairo::GObject) won't build against these binaries that we have in C:/usr/local. And if I use a Cairo::GObject that was built against different Gtk binaries, then the whole thing blows up.
Anyway, I guess we try and cross that bridge later ... or just jump off it.

These Glib based perl modules do all sorts of very cute stuff that make it difficult to hack. They're really designed to be built against a single complete set of Glib based binaries ... and we don't seem to have such a set for Windows. (We get some binaries from here, some others from there...)

Cheers,
Rob

Interesting, Rob. I ran into the same problem. I moved to a 32 bit XP box and went through the procedures and actually got G::O::I to build on that box. But like you when I tried Gtk3 I got the following:

C:\usr\local\Cairo-GObject-1.001>perl Makefile.pl

I wrote a perl script so I could keep track of the procedure. I built the script on my W7 box per your procedures, etc. It was that script that I ran on the XP box that allowed me to get G::O::I installed. But still no Gtk3.

Thanks,

Don

Here is the perl script I am messing around with. I'm just using it to ensure when I finally get Gtk3 installed and working I can reproduce the complete install again.
