[maemo-developers] Qemu Error on Maemo

[From: Deepak Kr. Sharma, Noida]

Thanks for your prompt reply.

It doesn't crash on x86. In the early stages of development it used to
work for ARMEL, but now it doesn't.

So once the application has been tested for x86, the app should be built
for ARMEL and tested on the device?

Regards,
Deepak

Scratchbox ARMEL target is mainly intended for building binaries and
packages, not for testing the produced binaries (it may work, but
qemu user-space emulation by necessity cannot be complete[1]).

You need to test your code on the device.

Does it crash also in the x86 target or on the device?

[1] System Qemu emulates more, but it's not included to or supported
by the maemo SDK.  Setting it up requires a lot of effort, but if
you're interested, you can find it with Google.
