Hello,

Thank you for the fix. It fixed our problem, too! I appreciate your great help.

We don't have any debugging tool for android native development. Without debugging tools, it's very hard to find bugs. If you don't mind, could you tell me how did you find it?

Best Regards, Yoshimi Fujii

Hello,

I also got a segmentation fault when trying to run my statically built executable. I debugged the segmentation fault and there was a line in EID.cpp (in ibrdtn/data folder) that was causing it. I changed that line and things worked after that.

I'm not sure if you are getting a segmentation fault for the same reason, but below is the change I made to the default constructor that fixed things for me

EID::EID() //: _scheme(DEFAULT_SCHEME), _ssp("none") // { //cout << "about to assign to _scheme" << endl; //cout << " DEFAULT_SCHEME = " << DEFAULT_SCHEME << endl; _scheme = "dtn"; _ssp = "none";

}

Hello,

We are still trying to build dtnd for Android using buildroot. Build seemed to be successful and 'file dtnd' shows:

"ELF 32-bit LSB executable, ARM, version 1 (SYSV), statically linked, not stripped".

However, when we run the binary, cause "Segmentation fault". What's wrong with us?

We built very simple application like "hello world" using buildroot and it runs on Android successfully.

Attached is the config file which we used for building dtnd.

Thanks, Yoshimi Fujii
