Hi, Im using arm-linux-gnueabi-gcc to compile dtc, inorder to use it on TWRP recovery, but when I run

~/dtc# make NO_PYTHON=1 CC=arm-linux-gnueabi-gcc CFLAGS=-static -s

it always say

dtc.o: In function `main':
dtc.c:(.text+0xd00): undefined reference to `dt_to_yaml'
collect2: error: ld returned 1 exit status
Makefile:338: recipe for target 'dtc' failed
make: *** [dtc] Error 1

Could you please tell me what to do , thank you!!!

The problem seems to resolve.

Here is my step:

~/dtc# make NO_PYTHON=1 CC=arm-linux-gnueabi-gcc

and then

~/dtc# make NO_PYTHON=1 CC=arm-linux-gnueabi-gcc CFLAGS=-static -s

then rm dtc and run again

~/dtc# make NO_PYTHON=1 CC=arm-linux-gnueabi-gcc CFLAGS=-static -s
~/dtc# file dtc
ELF 32-bit LSB executable, ARM, EABI5 version 1 (SYSV), statically linked, for GNU/Linux 3.2.0, BuildID[sha1]=e14f20a57ad58c674d2e5113299a7c2cf5ad9b3a, stripped

Just don't know why..
Sorry for bothering. Thank you.

Hm, I'm not really sure why that would be happening.

Do you have libyaml installed? This might happen if the NO_YAML variable was somehow being set differently for building the .o files and the final link, but I don't know why that would happen.
