Raspberry Pi 3 - 2.7.2 compile error with OpenH264

[Adam Rossi <ac.rossi@xxxxxxxxx>]

Howdy. PJSIP seems to be an amazing project!

I am attempting to compile the 2.7.2 release on Raspian 4.9.80 / RPi3.

I am able to compile pjsip successfully without openh264, but when I install it and try to recompile pjsip (which properly recognizes it), I get the error below in the vid_codec_test file. This happens regardless of my entries in config_site.h (#define PJMEDIA_HAS_OPENH264_CODEC    1 has no impact). 

my config_site.h file:

#define PJMEDIA_HAS_VIDEO       1
#define PJMEDIA_AUDIO_DEV_HAS_ALSA 1
#define PJMEDIA_AUDIO_DEV_HAS_PORTAUDIO 0

//tried just about every permutation of the following:
#define PJMEDIA_VIDEO_DEV_HAS_FFMPEG 1
#define PJMEDIA_HAS_OPENH264_CODEC    1
#define PJMEDIA_HAS_FFMPEG_VID_CODEC 1
#define PJMEDIA_HAS_FFMPEG_CODEC_H264 1

I can successfully compile with the ./configure --disable-openh264 flag.

Here is the compile error. Any ideas I should try?
