Make sure these libraries are in the path passed to linker with -L option.
I.e. find link command in your makefile, it's something like that:

$(LD) -L$(SDK_LIBDIR) ...

and check that SDK_LIBDIR is correct.

Thanks jcmvbkbc,

But it's ok, like you say, i will attach the Makefile...in fact this code was working, but when i try to install the sdk in another pc, i just cannot compile anymore. https://github.com/esp8266/esp8266-wiki/wiki/Toolchain This tutorial works 100% with sucess or i need to make standalone this https://github.com/pfalcon/esp-open-sdk ?

...and you have libc.a and all other missing libraries in the /opt/Espressif/ESP8266_SDK/lib on that other machine, right?
And you don't have SDK_BASE in your environment?

Well, it does one strange thing, it creates ESP8266_SDK directory, and then it mv unpacked directory into it. I believe it had to rename the unpacked directory. I'll fix that.
And I think esp-open-sdk should be preferred SDK setup method.
