Hello Lawrence,

Still running into some issues. I'm now building with the following, and
it's finding the OMX stuff

--extra-cflags="-I/opt/vc/include" --extra-cxxflags="-I/opt/vc/include"
--extra-libs="-L/opt/vc/lib"

However it's failing to build saying

/opt/vc/include/interface/vcos/vcos_types.h:38:33: fatal error:
vcos_platform_types.h: No such file or directory

(You can see the full build log at
https://launchpadlibrarian.net/227740383/buildlog_ubuntu-wily-armhf.mythtv_2%3A0.27.5%2Bfixes.20151126.9497495-0ubuntu8_BUILDING.txt.gz
 )

I've looked at the build log for libraspberrypi-dev and it does have a

/opt/vc/include/interface/vcos/pthreads/vcos_platform_types.h

(See the full build log for raspberrypi-firmware at
https://launchpadlibrarian.net/221014670/buildlog_ubuntu-wily-armhf.raspberrypi-firmware_1.20150918-1~wily1.0_BUILDING.txt.gz
 )

Any thoughts on this building error?
