Bus error(core dumped)

Biebs · 05-18-2021, 01:06 AM

I am running my application on arm-poky-linux target and before even the execution of main function the program is crashing and displaying this error.

Hi, and welcome here, at LQ.
Unfortunately dropping in an error message is not enough to help you.
Bus error most probably means there is an incompatibility somewhere amongst your libraries and executable (or just a coding issue). But without details hard to say more.

Hi,
thank you for the response I got the issue

I was getting bus error while including -lstdc++. How to resolve this

You included -lstdc++ in what?

If this happens even before the main function is called, I would suggest something is wrong with the format of the executable file. Or it calls an incorrect shared library, perhaps. strace may help you understand what happens.

Hi

Cross compiling using respective gcc and to include cpp object files including this flag but displaying a core dump when I do

pan64 · 05-19-2021, 01:22 AM

what kind of app is it? how did you build it? Do you have a coredump? What os/compiler is it?
Without real answers [at least] to these questions nobody can give you any help.

Describe the research you did to try and understand the problem before you asked the question.
Describe the diagnostic steps you took to try and pin down the problem yourself before you asked the question.

It's really hard to get information out of you. Your descriptions are very vague and non-specific. The quality of the answers you get will be proportional to the quality of your question.

My vague and non-specific guess is that the respective gcc is not appropriate for that platform/architecture.
