try this on machine with gcc 5.5 or earlier g++ compiler? (note there is typo in patch filename - must be libdpx)

That is a better solution so I will wait to see what you come up with.  The first patch, which had problems, would cause problems for many more people and we really, really want as many people to be able to build themselves without having to add new requirements that might not even work for older systems like ubuntu 16.

I think we can add this specific m4 macro from autoconf archive to our own m4 directory in source tree, but I'll test both ideas. New compiler defaults to new c++ mode anyway, but I guess old ones  also migh have some bugs in c++ support, so changing compilation mode for whole program sounds more dangerous than just for one file. 

also, while watching paint dry.. err, watching cin compile on emulated powerpc I noticed we already override cxx standard for fileexr (look for c++11 in cinelerra/Makefile) so hopefully same can be done for filedpx

ow. 

does autoreconf fixes this? 

https://stackoverflow.com/questions/27673292/ax-cxx-compile-stdcxx-11-macro-not-found

autoreconf --install --force

if not - look for aditional autoconf-archive package? (not sure about fedora's packaging)

also add pkg-config based check for libva's location

alsoI think my patches for aborting compile if withzmpeg = no and v4l2/dvb = yes need  || test case for xauto...
