I am following up on my previous post (see below). I've noticed that if I add a -static flag under _LDFLAGS in Makefile.am, it compiles fine.
I am wondering if it's ok to compile with the -static flag. In an attempt to be able to compile without the static flag, I reinstalled the ffmpeg libs with the --enable-shared option, so the .so libs are installed as well. But even with that if I do 'make' without the '-static' flag in Makefile.am, it fails to compile, much like it did earlier... Anyone knows what might be happening?
