[Boost-users] GIL: New file io, almost there, but can't compile 'write_view'

So, I had to deal with a lib I worked on last a couple of years ago. 
Great news, the file IO has been greatly simplified in 1.68. I was able 
to retire several dozens of cryptic,(for me), lines. The old code won't 
compile as the Adobe extensions are gone. I'm almost there, I can read 
files, but I don't understand why I can't get the writer to compile.

I get to my code, in case it matters:
 Â Â Â  Â Â Â  bg::rgb8_image_t destImg( res, x );
 Â Â Â  Â Â Â  resize_view( view( sourceImg ), view( destImg ), 
bg::bilinear_sampler( ) );

and rgb8_image_t should be a good one from what I read:
<https://www.boost.org/doc/libs/1_68_0/libs/gil/doc/html/io.html>

With either:
 Â Â Â  Â Â Â  bg::write_view( path_to, destImg, bg::jpeg_tag() );
or:
 Â Â Â  Â Â Â  bg::image_write_info<bg::jpeg_tag> write_setttings;
 Â Â Â  Â Â Â  bg::write_view( path_to, destImg, write_setttings );

ms140 complains:
1>C:\cpp\boost_1_68_0\boost/gil/extension/toolbox/metafunctions/get_pixel_type.hpp(33): 
error C2039: 'reference': is not a member of

What am I missing? Do I need to supply more information? I'll put the 
whole thing in a url if needed.
Thanks, Dan.
