Hiu isti37.
Is this for a commercial project or is there a chance you would consider sharing the code/project?
Kind regards
Jimmy

Hi,

It seems that your makefile is not for ESP8266, you need to re-write the makefile.

I am trying to cross compile the opus codec for the ESP8266, currently I have hit the following errors :
