Issues in building qt for beagleboard xm and remote debugging

hi,
I built a small multithreaded application in qt. Previously I debugged using gdb remote debugging in qt. Suddenly I dont know what happened, my debugger always fails while launching
and I have the following error.

<49-exec-run

49^error,msg=“Don’t know how to run. Try “help target”.”

dDon’t know how to run. Try “help target”.

Also first I tested my application in my host(x86) and while compiling it dint have any issues. When I compiled it for ARM target I had the following issues:

In file included from /data/Sitara/linux-devkit/arm-arago-linux-gnueabi/usr/include/qtopia/QtCore/qobject.h:48:0,

But my executable is getting generated anyway. Should I ignore this issues or should i consider??

Thanks

Sorry for my stupidity!! The problem is with my Run Settings in qt. But the issues are still there. Is it ok to leave them?
