Marcus and List,
I was hoping someone knew the steps involved to get the RTIMULib setup on the
USRP. I tried building and installing both the RTIMULib and Linux folders, but
the Linux one fails:
-- Found unsuitable Qt version "" from NOTFOUND
Qt QTOPENGL library not found.
Qt QTGUI library not found.
Qt QTCORE library not found.
CMake Error at RTIMULibGL/CMakeLists.txt:90 (QT4_ADD_RESOURCES):
Unknown CMake command "QT4_ADD_RESOURCES".
-- Configuring incomplete, errors occurred!
I figured that I can't install the RTIMULibDemo apps because they use a GUI, so
I built and installed the RTIMULibDrive and RTIMULibCal individually. Only,
when I try to run one of these apps I get the following error:
RTIMULibDrive: error while loading shared libraries: libRTIMULib.so.7: cannot
open shared object file: No such file or directory
I don't get how to fix this. When I build and install the same apps on my host
computer they run fine (but obviously can't find any IMU). Considering that any
applications I write also use the same libraries, I feel like this is going to
be an issue.
There isn't any documentation that I can find on the usage of the C++ library
for RTIMULib. Just reading the code in RTIMULibDrive.cpp as an example, it
doesn't seem too complicated, but it obviously is a generic program that isn't
using the settings needed to connect to the MPU-9150.
If anyone knows how to get one of these apps (RTIMULibDrive or RTIMULibCal)
working or how to use RTIMULib.h in connecting to the MPU-9150 over I2C, it
would be much appreciated.

P.S. I also tried 'i2cdetect -y 0' to see if the MPU-9150 has the I2C address
0x69 like the schematics say, but I only get:
Warning: Can't use SMBus Quick Write command, will skip some addresses
0 1 2 3 4 5 6 7 8 9 a b c d e f
00:
10:
20:
30: -- -- -- -- -- -- -- --
40:
50: UU UU -- -- -- -- -- -- -- -- -- -- -- -- -- --
60:
70:
with nothing under 0x69. So that's weird.
