I'm trying to configure the toolchain on Ubuntu 14.04. I got to compiling the examples, but can't make blinky. When I try to compile I get missing -lhal linker error. I downloaded libhal form here: http://packages.ubuntu.com/precise/libhal-dev
but still no result. Now I get
skipping incompatible /opt/Espressif/ESP8266_SDK/lib/libhal.a when searching for -lhal
BTW. I also had problem with linker not finding libc. Managed it with moving it to SDK/lib directory, but I expected the basic examples to work more out-of-the-box.
