Hi Aaron,

This mailing list is intended for the development of FFmpeg itself. It
sounds like you're working on your own project or personal
customizations (without the plan of trying to upstream the changes
into the mainline FFmpeg code), in which case the libav-user mailing
list sounds like the more appropriate mailing list to use.

You shouldn't be adding C++ flags to C flags (they're different
languages, after all). You can use the --extra-cxxflags= parameter in
./configure to pass extra C++ flags to the compiler.
