2015-12-30 16:15:30 -0600 asked a question compiling MAVROS generates error

We need to build MAVROS from source and are getting the following error:

 [ 88%] Building CXX object mavros/mavros/CMakeFiles/mavros_plugins.dir/src/plugins/altitude.cpp.o
/home/john/catkin_ws/src/mavros/mavros/src/plugins/altitude.cpp: In member function ‘void mavplugin::AltitudePlugin::handle_altitude(const mavlink_message_t*, uint8_t, uint8_t)’:
/home/john/catkin_ws/src/mavros/mavros/src/plugins/altitude.cpp:61:71: error: ‘mavlink_altitude_t’ has no member named ‘time_usec’
         ros_msg->header = uas->synchronized_header(frame_id, altitude.time_usec);
                                                                       ^
make[2]: *** [mavros/mavros/CMakeFiles/mavros_plugins.dir/src/plugins/altitude.cpp.o] Error 1

The source was obtained from https://github.com/mavlink/mavros and receive the same error when trying https://github.com/vooon/mavros as well. I tried straight GIT cloning as well as WSTOOL to install source and used catkin_make. This was generated on an Ubuntu Trusty version with ROS Indigo.

Any advice would be greatly appreciated,

I have generated a remote point cloud. Thanks to piggy backing Kalectro's work I was able to stream the depth image to a laptop (as ros master) that I simply copied and reduced all openni_launch files to just depth processing in the processing include launch file changing the camera parameter to openni2_camera. My spin was transporting the stream off my Mike Ferguson Arduino based robot with a second Raspberry Pi acting as a wireless bridge with a cat5 crossover cable to the XTION connected Pi (because its USB is to bogged to transmit 802.11 usb). Thanks Mike and Kalectro for a cool Raspberry Pi Turtlebot Navigation capable robot!
