Building decklink for windows using cerbero

[Felipe Mogollon]

Hi,

I am trying to build decklink (Blackmagic) plugin into windows using
cerbero but I can't get any result.

I am using debian 8.0 as host machine

I have made:

./cerbero-uninstalled -c config/cross-win64 bootstrap
./cerbero-uninstalled -c config/cross-win64 build gst-plugins-bad-1.0

successfully but no libgstdecklink.dll is created.

If I dive into gst-plugins-bad-1.0/sys/decklink folder I can see that there
is a Makefile that has been generated but It doesn't work.

It has several errors:

* Cannot find mingw compiler
* Cannot find pthread.h
* Cannot find dlfcn.h

I could solve those issues by adding my mingw compiler to PATH manually and
adding include paths to those headers manually to the Makefile file.

But when I run again make I get the following error:

I have checked that there were some changes to support decklink windows in
the last months but I am not able to get it working.

Am I doing something wrong? Is there any step I am not doing ok?

Regards

Felipe
