Qemu: uncaught target signal 11 (Segmentation fault) - core dumped

[jiapei100]

Hi, all:

Working Environment:
OS: Ubuntu 18.04
QEMU: Default from repository

$ qemu-arm --version
qemu-arm version 2.11.1(Debian 1:2.11+dfsg-1ubuntu7.1)
Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers
$ qemu-system-arm --version
QEMU emulator version 2.11.1(Debian 1:2.11+dfsg-1ubuntu7.1)
Copyright (c) 2003-2017 Fabrice Bellard and the QEMU Project developers

A simple code "Hello World" is successfully compiled but failed to run from within Eclipse (I've already configured Eclipse from Window->Preferences), with the following ERROR message:

qemu: uncaught target signal 11 (Segmentation fault) - core dumped

Can anybody give me a hand please?

Cheers
Pei

@jiapei100,

You could try enabling core dumps by following steps similar to those in this article: https://www.cyberciti.biz/tips/linux-core-dumps.html

Then when your program crashes, a core file should be generated in the path you specify for kernel.core_pattern. You should then be able to use gdb <executable binary> <path to core> to inspect the core file and see where the seg fault occurred.

Regards,
Tom

Hi...from the information you've provided, I'm not sure what this has to do with qemu-system-ppc?
If I understand you correctly, you're attempting to compile software in Eclipse inside a precompiled qemu-arm guest (which OS?) running on Lubuntu 18.04?Or are you trying to compile qemu-ppc and getting a segmentation fault, but not with qemu-arm?
