For Developers
1

During building for my minimum requirements, an error worked which requires a patch.

Error syntax

usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x50): multiple definition of 'yylloc'; scripts/dtc/dtc-lexer.lex.o:

Fast fix:

#include "srcpos.h"
#include "dtc-parser.tab.h"

extern YYLTYPE yylloc; // OLD CODE: YYLTYPE yylloc;
extern bool treesource_error;

/* CAUTION: this will stop working if we ever use yyless() or yyunput() */
#define	YY_USER_ACTION \

or patch:

diff --git a/scripts/dtc/dtc-lexer.l b/scripts/dtc/dtc-lexer.l

@xootkama,
I wrote a solution to the patch problem. If explained in words, find lines

YYLTYPE yylloc; in /scripts/dtc/dtc-lexer.l
YYLTYPE yylloc; in /scripts/dtc/dtc-parser.tab.c_shipped

and replace to

extern YYLTYPE yylloc;
