Espressif ESP8266 NONOS_SDK - Makefile - makefile

Question

I would like to compile my source-code for the ESP8266 (Extensa NONOS_SDK Toolchain is already installed and working).
This is my folder structure:
I use this Makefile from an example from Espressif: https://github.com/espressif/ESP8266_NONOS_SDK/blob/master/examples/simple_pair/Makefile
and I also use this gen_misc.sh: https://github.com/espressif/ESP8266_NONOS_SDK/blob/master/examples/simple_pair/gen_misc.sh
I am running Ubuntu 18 as a Linux Subsystem for Windows 10. This is how I called gen_misc.sh from cmd:
./gen_misc.sh
gen_misc.sh version 20150511
Please follow below steps(1-5) to generate specific bin(s):
STEP 1: choose boot version(0=boot_v1.1, 1=boot_v1.2+, 2=none)
enter(0/1/2, default 2):
0
boot mode: old
STEP 2: choose bin generate(0=eagle.flash.bin+eagle.irom0text.bin, 1=user1.bin, 2=user2.bin)
enter (0/1/2, default 0):
0
ignore boot
generate bin: eagle.flash.bin+eagle.irom0text.bin
STEP 3: choose spi speed(0=20MHz, 1=26.7MHz, 2=40MHz, 3=80MHz)
enter (0/1/2/3, default 2):
2
spi speed: 40 MHz
STEP 4: choose spi mode(0=QIO, 1=QOUT, 2=DIO, 3=DOUT)
enter (0/1/2/3, default 0):
2
spi mode: DIO
STEP 5: choose spi size and map
0= 512KB( 256KB+ 256KB)
2=1024KB( 512KB+ 512KB)
3=2048KB( 512KB+ 512KB)
4=4096KB( 512KB+ 512KB)
5=2048KB(1024KB+1024KB)
6=4096KB(1024KB+1024KB)
7=4096KB(2048KB+2048KB) not support ,just for compatible with nodeMCU board
8=8192KB(1024KB+1024KB)
9=16384KB(1024KB+1024KB)
enter (0/2/3/4/5/6/7/8/9, default 0):
4
spi size: 4096KB
spi ota map: 512KB + 512KB
This is what I get as output:
start...
make: Nothing to be done for 'FORCE'.
Any ideas or help what I am doing wrong are greatly appreciated.
Please don't hesitate do ask if I didn't include any information you might need to answer this question.

Answer 1

the solution as suggested here is to copy the folder where you are running the script to the root of the sdk folder and run the script.
