Hi everyone,
I have an issue when I was running the make file for the Pololu USB SDK. After running the make file I get the following error:
make: warning: Clock skew detected. Your build may be incomplete.
Also when trying to run the MaestroAdvancedExample executable I get the following from the command line:
linaro@linaro-ubuntu-desktop:~/Downloads/pololu-usb-sdk/Maestro/MaestroAdvancedExample$ ./MaestroAdvancedExample

Got a SIGSEGV while executing native code. This usually indicates
a fatal error in the mono runtime or one of the native libraries
used by your application.
=================================================================
Aborted
I also get a similar error when running the Maestro Control Center.
The computer I am running is an ODROID-U2 (Quad core ARM Cortex-A9 MPCore) with Ubuntu 12.11 Linaro. I was wondering if anyone else experienced this or what the fix is. Thanks in advance for all the help.
