A quick and dirty fix is to patch Makefile.open in the esp-open-lwip dir:

I'll let @pfalcon fix this as here probably some env variable of VENDOR_SDK_DIR has to be propagated.

After adding this patch I am getting following error: -- I may not have added patch correctly.

Same problem here but only if compiled with "STANDALONE=n"
@drasko patch fixes the issue.

A change which should fix this was pushed. If you still have any
issues, be sure to provide all the steps required to reproduced the
issue on a fresh system.

It works with "STANDALONE=y" but same issue otherwise.

It's broken for me too, on a fresh clone. Note that I built it with STANDALONE=y

@Ghostbird You still have to use solution from #94 to fix the issue for Installing pass-2 core C compiler.. Once you do that it works.

Ah, I had to use sed instead of gsed, and I just used a rather sloppy one-liner, but it worked.

sed -i '1s/^/#include <stddef.h>\n/' crosstool-NG/.build/src/gcc-4.8.2/gcc/graphite*.c

Thanks for the help

This still occurs on the latest master, with STANDALONE=n

Please see the attached console.log to confirm the following:

I've also included the full build log, the important part is:

Pull request #148 should fix this issue.

This issue is really annoying. Can anybody tell which is the last commit this did work, then I'll revert to that.

@sappo: You should just build with "make" and there're no issues.

@pfalcon Thanks for the quick response. Just "make" works fine indeed 👍

This was resolved.
