Error after entering 'make'

[nisc3]

I'm getting this error when I run make command

I'm using Rpi3

You are getting this when you try to build the esp-open-sdk? You are following the instructions on https://github.com/pfalcon/esp-open-sdk ?

On which OS? I did all my builds on Linux, but the project uses the standard makefile, so there should be nothing specific here? Can you build any other ESP sample project?

I'm running Raspbian Jessie on rpi3. I was able to compile the esptool SDK 2.0.0 for ARM which I'm using now

Can you now replace the esp-lwip-open tree with my code from here https://github.com/martin-ger/esp-open-lwip and do the build again?

[nisc3]

I removed the entire contents from that folder and added yours, still no luck...

I made it work by flashing firmwares from a windows PC, had a lot of problems when tried to compile with raspberry pi

[martin-ger]

I am just building the esp-open-sdk on a raspi - it takes... "forever". Maybe it is completed tomorrow. Then I will look into it, where there might be problems....

After 16h of building the esp-open-sdk and especially the gcc on my Raspi B it failed with some unclear error during linking of phase 1 of gcc (which is even half way of building the SDK), It seems to me that using a Raspi it not a verry good idea and I am not able to further dig into that.

If you only have a windows machine, a VirtualBox with a minimal Ubuntu is perhaps a better choice - this worked for me...
