Hi Carl
--extra-ldflags=-ldl
That's fixed it!

config.mak now shows:-
"CONFIG_FFPLAY=yes"
(no exclamation mark!)

and the "undefined reference" messages have disappeared from config.log.

Thanks. :-)

ps
FFplay has built OK but it isn't working properly yet. I'll investigate this next.

$ ldd ./ffplay
	not a dynamic executable
