Hi,

Looks like you are missing a reference to the libsmartconfig.a file. Please try adding it to your project (or adding “smartconfig” to the Library Names field in the Linker Settings).

Hello.

I am having the same problem. However I cannot find where this library is located, I searched my PC and it is not there. Also, when I find it, how am I going to add it to my project?

If I go to properties->Linker, what should I do next?

Thanks.

[kostbill]

OK, did it but I had to download the library from the net. It was not in my PC.

Hi,

Our ESP8266 toolchain only includes the libraries shipped with the RTOS and non-OS SDKs; if you want to use external libraries, you indeed need to download them (we recommend saving them outside the toolchain directory to avoid losing them during a toolchain update).
