issues building

[mzimmers]

Hi -

I'm looking forward to getting this software to build. Currently, I'm attempting to build using esp-idf v4.1, and v8.2 of the toolchain. Target will be a proprietary board using the WROVER.

I'm getting two build errors:

1. multiple definitions of if_indextoname(). This appears to be part of a workaround for an asio bug, but I wonder if the definition in lwip_udp_client.h may now be an anachronism.
2. undefined references to several routines that appear to be C++ error handling routines, eg. _Unwind_Resume.

Thanks for any assistance on this.

Thank you for reporting this.

See also espressif/esp-idf#4490 After upgrading to the current master and ensuring that you use a supported toolchain, you have to run:

idf.py fullclean

After that also your 2nd error should be gone. I have not tested this on hardware, yet.

Thank you Christian. I did a full clean on my project, and I believe my toolchain is supported:

This eliminated the C++ error handler errors; I'm still getting the duplicate definition error, though.

I'm still getting the duplicate definition error, though.

Have you pulled my latest change? It is working for me in linux.

You fixed this since yesterday? Anyway, yes, it builds now...thanks for the help. I'm sure I'll have more questions down the road.

Yes, see the linked commit above. Glad to hear that it works now.
