The armel target is not meant to actually run or debug applications, but only to compile them to use in the device. Yes, this is because Qemu does not completely emulate the ARM processor. However, if you have a real ARM device, you could set up Scratchbox to use CPU transparency over network to run the binaries in the real ARM processor (like we did back in 2004-2005). -Kimmo ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
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.

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

Re: Can't debug an application under FREMANTLE_ARMEL target in Scratchbox
That's true, but sometime it happens that an application which runs just fine under FREMANTLE_X86 immediatly crashes when executed in the device itself. It occured to me with the last version of grsync (in extras-devel and -testing) and I'm waiting for the real device to try to understand what's happening. -- Luca Donaggio On Tue, Nov 24, 2009 at 6:02 PM, Alberto Garcia agar...@igalia.com wrote: On Tue, Nov 24, 2009 at 07:55:47PM +0300, Burka Victor wrote: I'm trying to debug very simple application under FREMANTLE_ARMEL target and can't do that.

Yes, and there is another way to run your app in Scratchbox. To run emulator first then run your app inside the emulator. And it works for Diablo. I have not touched Fremantle but be curious that it should be a similar one there. yalong Berto ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers ___ maemo-developers mailing list maemo-developers@maemo.org https://lists.maemo.org/mailman/listinfo/maemo-developers
