- Tue May 05, 2015 6:35 am #16545 I can compile node-mcu
I can compile blinky, interrupt_example
However, none of the examples in ESP8266_SDK/examples like IoT_Demo or at can be compiled: I get the following

Code: Select allmake
../../Makefile:151: warning: overriding commands for target `clean'
../Makefile:258: warning: ignoring old commands for target `clean'
You cloned without --recursive, fetching submodules for you.
git submodule update --init --recursive
make -C crosstool-NG -f ../Makefile _ct-ng
make: *** crosstool-NG: No such file or directory.  Stop.
make: *** [crosstool-NG/ct-ng] Error 2


Why is that thing trying to go to the crosstool again and build it. Why that very complex makefile structure and going up again one level up and trying to so things there???
It just needs to go the source files in the usr include and so on and just compile them using the xtensa toolchain that is already there and produce the bin images.

I am not expert in makefile, but was anyone able to compile the IoT_Demo code?

I was able to use the sample makefile from https://github.com/pfalcon/esp-open-sdk/issues/6
to compile th IoTDemo on SDK esp_iot_sdk_v0.9.5_15_01_23
Here is it. Make sure your makefile lines in lines with $(CC) esptool and so on are preceded by tabs not spaces.

Code: Select allCC = xtensa-lx106-elf-gcc
CFLAGS = -Os -Iinclude -mlongcalls -DICACHE_FLASH
LDLIBS = -nostdlib -Wl,--start-group -lmain -lupgrade -lnet80211 -lwpa -llwip -lpp -lphy -Wl,--end-group -ljson -lcirom -lgcc
LDFLAGS = -Teagle.app.v6.ld

- Thu May 07, 2015 2:41 am #16763 Regarding the esptool "issue". It's not included in the sdk, also iirc the source isn't even available. Simple solution: use esptool.py, it also knows how to make image files and is included in the sdk. It beeds a small change to the Makefile though.

- Fri Jul 17, 2015 11:33 am #23511 Thanks to @kelsayed, I was able to make a Makefileto build the IotDemo that works with the latest sdk as of this post (esp_iot_sdk_v1.2.0). Espressif moved a lot around, removed the pwm source, and did some other random things.

Here it is, if anyone wants it. Replace the Espressif broken Makefile and remember to change spaces to tabs if you cut and paste.
