SIGSEGV:Segmentation fault while debugging in QNX Neutrino target as a virtual machine   
Hi,

I am new to QNX. I have created a "Hello World" qnx executable project. I am debugging it on a target (qnx image loaded 
via VMWare player). IDE is connected to target via qconn. 

Running the program works. But when I am debugging, I am getting the below error.

Thread #1 unnamed (STOPPED) (Suspended : Signal : SIGSEGV:Segmentation fault)	

Debugger console has following information. Please help.

MsgNak received - resending
Remote target is little-endian
warning: Shared object "/home/uib55281/qnx700/target/qnx7/x86_64/lib/libc.so.4" could not be validated and will be 
ignored.
warning: Could not load shared library symbols for /usr/lib/ldqnx-64.so.2.
Do you need "set solib-search-path" or "set sysroot"?
warning: Host file /usr/lib/ldqnx-64.so.2 does not match target file <?>

Re: SIGSEGV:Segmentation fault while debugging in QNX Neutrino target as a virtual machine   
Does your target reports that is x86_64 or x86?
Both your host is target have 7.0?

My target is x86_64. (QNX SDP 7.0 x86-64 virtual machine for VMware)

Yes I have 7.0.

Target libc does not match host libc, its either mean its different 
architecture or different version
Did you install debug symbols for libc? In software center right click 
Install Debug symbols in Kernel & Libc package

Re: SIGSEGV:Segmentation fault while debugging in QNX Neutrino target as a virtual machine   
Thanks for the suggestion. I just installed kernel and libc package via software center.
It is working now. I can debug.
Thanks again.
