Thanks for the info, I have to take a look at 0.9.6. And by the way, it would be great if Espressif provided SDK_VERSION define... but they don't.

thank you for bringing us lwip from sources!
I wanted to have my ESPs showing up with a host name in the DHCP-Lease list on my WiFi router so I added liblwip.a generated with

Code: Select allmake USE_OUR_LWIP_IF=1

.

In my router there is a name shown, but not as expected. It is displayed as "---?(".
Do you have an idea what i did wrong?

best regards

I suspect the issue is described by pvvx above but I am not quite sure what to do to fix it.

Also I would like to ask if this lirbary will allow the esp to have a custom hostname picked by user_config when defining it as LWIP_NETIF_HOSTNAME_PREFIX?
