Compile error: dupe definitions with Asterisk-13.1 and gcc-5

[herczegzsolt]

Everything seems fine until make command, which gives me a very long error list of "multiple definition". make_output.txt

Next time, the steps preceding the make would've been nice.

And the gcc version.

But I think I can add two and two together and conclude that: (a) you run Debian or a derivative with a very old Asterisk 13.1 (b) you run quite a new gcc 5 compiler

That means you lack this changeset: https://github.com/asterisk/asterisk/commit/e48f2e7897079936ef2cb91fd15b88c319a3cdc9#diff-47b4c4af4bc4e5e2b56157c25afbbe86L51

This should do the trick for you:

I'm very sorry, I wanted to attach the additional information. The affected system is Ubuntu 16.04 LTS, so I think the problem will persist for a longer time.

Preceeding steps was: git clone https://github.com/wdoekes/asterisk-chan-dongle.git cd asterisk-chan-dongle/ aclocal autoconf automake -a ./configure --with-astversion=130100 make

Thank you very much for the patch, it solves the compilation problem! However I did not recompiled asterisk which your patch applies to, so I don't know if the binary will work or not. I'll test it, and provide feedback.

[herczegzsolt]

The chan_dongle compiled with the patch seems working OK. There are some instability when the dongle is "reused": Dongle needs reset before every asterisk start. I assume it's not related.

Thank you very much for your excellent support, feel free to let me know if I can do anything in return.

[wdoekes]

Glad it works. And no, you did not / should not have to recompile asterisk.

As for the reset before reuse, that should very much be unrelated indeed. You'll need to come up with a lot more debug output to get that fixed ;-)
