I tried to build and run the advanced_examples\dlna example, my installation runs on Windows and everything is default and up2date.
After running build i get:

The problem seems to originate in libesp_upnp.a, I'm using the latest commit:
Commit hash: 24b500ca688cfcd84ee30c7d7cc7ae9361d31e11
but also tried it with release V2.0 (Commit hash: a3be5b2fcaff02e9303e46a9d8b0f34d0d34f9bb) and got:

Hello - I was facing the same type of error messages (trying the IDF V4.1) with the ssdp library from ADF. I thought all was up-to-date as I did a git pull at ADF_HOME top level which was already origin/master.

Long story short I also did a git pull under esp-adf-libs (which is under ADF_HOME/components and this fast forwarded me to origin/master. The ssdp linking error then disappeared. So it seems the 'libraries' were out-of-date. Perhaps if anyone else has the same errors, then give this a try.
