Right, I used 'empty' in a somewhat loose sense. registry.i586.bin is 
small (<= 25kB instead of > 200kB) and running strings on it shows 
all plugins are blacklisted:

$ strings .cache/gstreamer-1.0/registry.i586.bin | head -n12
1.3.0
libgstcoreelements.so
Plugin for blacklisted file
/usr/lib/gstreamer-1.0/libgstcoreelements.so
0.0.0
BLACKLIST
BLACKLIST
BLACKLIST
BLACKLIST
libgstcoretracers.so
Plugin for blacklisted file
/usr/lib/gstreamer-1.0/libgstcoretracers.so

That's a clear result of the 64-bit gst-plugin-scanner being unable to 
load the libraries to see what they contain. Contrast it with the 64-bit 
file:

$ strings .cache/gstreamer-1.0/registry.x86_64.bin | head -n12
1.3.0
coreelements
GStreamer core elements
/usr/lib64/gstreamer-1.0/libgstcoreelements.so

That's a pretty interesting page. I took the instructions and integrated 
them in the wt-install-dev script I maintain for wt-daily (for running 
the Wine tests daily).

It has the advantage of making the instructions testable, reproducible 
and hopefully easier to run:

wget https://raw.githubusercontent.com/fgouget/wt-daily/master/wt-install-dev && sh wt-install-dev

Here are some things I found while writing / testing it on openSUSE 15.1:

* MinGW does not seem to be readily available. Compiling Wine without 
  MinGW is likely not to get tested much in the future so that's 
  concerning.

* A number of -devel-32bit packages don't depend on package that 
  contains the libraries, resulting in unusable dead links. The culprits 
  are:
    fontconfig-devel-32bit
    libgphoto2-devel-32bit
    libpulse-devel-32bit
    libv4l-devel-32bit
    openal-soft-devel-32bit
    sane-backends-devel-32bit
    vulkan-devel-32bit

* gstreamer-devel-32bit is missing but installing glib2-devel-32bit and 
  creating some symlinks seems to be enough to compile 32-bit GStreamer 
  applications. That's good.

* There are a couple other missing -devel-32bit packages that the script 
  works around by creating the missing symlinks:
    libnetapi-devel-32bit
    Mesa-libGL-devel-32bit!

* There is no OpenCL 32-bit package at all (ocl-icd-devel-32bit and 
  libOpenCL1-32bit are both missing). And for 64-bit one needs both 
  opencl-headers and ocl-icd-devel. OpenCL is all around weird.

* The following packages don't seem to be necessary:
    bison-32bit
    freeglut-devel*
    giflib-devel* 
    bopenssl-devel*
    xz-devel*

* Other missing libraries. If someone figures out a clean way to script 
  these or has good documentation I can link to:
    FAudio-devel
    prelink (not a lib)
    vkd3d-devel

I'm hoping this can help Wine developers get started on openSUSE.
