Can't debug an application under FREMANTLE_ARMEL target in Scratchbox
|
|
Hello,
I'm trying to debug very simple application under FREMANTLE_ARMEL target and can't do that. What I got is the following:
1. The application:
#include <iostream>
using namespace std;
int main(int argc, char * argv[])
{
cout << "Hello 1" << endl;
return 0;
}
2. The build command:
[sbox-FREMANTLE_ARMEL: ~/Projects/simple] > g++ -Wall -g -o simple main.cpp
3. The debug command. I tried both :
3.1.
[sbox-FREMANTLE_ARMEL: ~/Projects/simple] > gdb simple

(gdb) run

Don't know how to run. Try "help target".
(gdb)
3.2.

Hello 1
/home/bifh6/fremantle-arm-prereleased.cs2007q3/work/gdb-6.8.50.20090417/gdb/linux-nat.c:2973: internal-error: linux_nat_wait: Assertion `status == 0' failed.
A problem internal to GDB has been detected,
further debugging may prove unreliable.
Quit this debugging session? (y or n)
-----
So everything works fine under FREMANTLE_X86 target if I type "native-gdb simple" but I want to understand why it doesn't work on FREMANTLE_ARMEL.
I also tried some simple Qt application on FREMANTLE_ARMEL. I run it and the debugger accepted the "break main.cpp:5" command but didn't stop there despite this is the first line of application in main function. The same application stopped in that line under FREMANTLE_X86
If anybody knows how to solve that problem, I would appreciate that.
Regards,
Victor
