Many thanks for putting this all together, it's working great. I was using "esp-open-sdk"; that worked fine but I got tired of messing with Makefile.

My projects are using "tuanpmt" great MQTT implementation https://github.com/tuanpmt/esp_mqtt

With so many code bases out there and different make files, this sdk is easy to adopt to them.

I've attached a working Makefile for "esp_mqtt".

-Cheers!

I would like to add functionality to the dhcpserver .
After a lot of messing around , I managed to get lwip compiling with a project & not using the liblwip .
BUT , it doesn't work properly when loaded into the modules.
Logs report it connecting to an AP successfully then I get

etc ....


I believe the LmacRxBlk entries are generated from functions in libpp but I don't have the code for that .
Has anyone got lwip compiling & working with the DevKit ?

- Fri Feb 13, 2015 3:38 am #9619 Your messages looks like you did something wrong with regards to lwip ABI compatibility with SDK. I guess you changed something in LWIP code or configuration? You should first try to get unmodified lwip working, then change it.

You can take a look at my https://github.com/kadamski/esp-lwip I haven't tried compiling it on Windows but it has very simple Makefile so it should be quite easy to adopt (and patches/instructions for that are welcome). Maybe that will help?

Got it working in eclipse .. Ye Ha !
Here is my modified Makefile .
