Solution for "'multiple definition of yylloc' error #4

c-shankar · 2020-07-22T08:41:58Z

If you are facing the following error,

usr/bin/ld: scripts/dtc/dtc-parser.tab.o:(.bss+0x10): multiple definition of 'yylloc'; scripts/dtc/dtc-lexer.lex.o:(.bss+0x0): first defined here

collect2: error: ld returned 1 exit status

edit the file ./linux-rtk/scripts/dtc/dtc-lexer-lex.c
Find the line 'YYLTYPE yylloc' and change it to 'extern YYLTYPE yylloc'

The possible reason is wrong version of GCC. Please try gcc-9 or older.
Previously, I used gcc-10, and got this issue. Then installed gcc-9, and everything were successfully build.

dtc-lexer-lex.c

I met this issue when I build android7 in ubuntu22. But why am I not found dtc-lexer-lex.c in aosp path

Pranav-flo · 2022-05-29T09:51:52Z

This issue occurs during kernel compilation. I resolved it by adding extern to yylloc.
You can find the file in (root directory of kernel folder)/scripts/dtc/dtc-lexer-lex.c
Also if dtc-lexer.lex.c_shipped file exists in the path make sure to extern yylloc here as well.

hamzajrifi · 2022-06-11T18:40:54Z

that's same happen with me when update gcc-9 to gcc-11
and i fixed it when i receive my last version gcc-9 and that's work whit me
i used this command
==> sudo update-alternatives --install /usr/bin/gcc gcc /usr/bin/gcc-9 9

If you are facing the following error,

In some RK SDK, this symbol is placed in the file dtc-lexer.l

MadhbhavikaR · 2022-10-30T09:27:45Z

I was able to resolve the issue by applying the below patch (the file name was different in my case)

$ git diff

wbob · 2022-11-20T22:59:16Z

was stuck on this for too long - ignored the _shipped files at first. For context: those are being used in kernels prior to 4.17, see torvalds/linux@e039139be8c2 and https://lkml.org/lkml/2020/3/31/658

you need the patch in kernels < 5.6

commit e33a814e772cdc36436c8c188d8c42d019fda639 upstream. gcc 10 will default to -fno-common, which causes this error at link time: (.text+0x0): multiple definition of `yylloc'; dtc-lexer.lex.o (symbol from plugin):(.text+0x0): first defined here This is because both dtc-lexer as well as dtc-parser define the same global symbol yyloc. Before with -fcommon those were merged into one defintion. The proper solution would be to to mark this as "extern", however that leads to: dtc-lexer.l:26:16: error: redundant redeclaration of 'yylloc' [-Werror=redundant-decls] 26 | extern YYLTYPE yylloc; | ^~~~~~ In file included from dtc-lexer.l:24: dtc-parser.tab.h:127:16: note: previous declaration of 'yylloc' was here 127 | extern YYLTYPE yylloc; | ^~~~~~ cc1: all warnings being treated as errors which means the declaration is completely redundant and can just be dropped.

补充一下，不用重装gcc，找到这个文件，查找"YYLTYPE yylloc;"这一行，替换成"extern YYLTYPE yylloc;"即可。

Kernel build successful after modifying dtc-lexer-lex.c in < kernel src directory>/scripts/dtc/
YYLYTYPE yylloc ==> extern YYLTYPE yylloc

( jfyi - I encountered this issue while building a custom linux arm kernel for qemu.

kernel tar source - linux-4.4.157 ( issue is specific to src file dtc-lexer-lex.c, and is fixed in version v4.17-rc1 and above)
gcc version - 11.3.0 on the host system running kernel 5.19-0.46
)

Hello,

您可能没有清理旧的obj文件，请先删除“dtc-lexer.lex.o”然后构建，或者先全部清理（一般为make clean之类的命令）再重新构建。
Perhaps you didnot clean old obj file, please delete “dtc-lexer.lex.o” and build again, or clean all(some sort of command like "make clean") and rebuild again.

This worked for me. I was trying to compile an android 4 kernel and kept getting this error.
