Subject: [PATCH] scripts/dtc: Remove redundant YYLOC global declaration
|
||||
|
||||
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.

Intro
|
||||
=====
|
||||
|
||||
This default configuration will allow you to start experimenting with the
|
||||
buildroot environment for the A64-OLinuXino. With the current configuration
|
||||
it will bring-up the board, and allow access through the serial console.
|
||||
|
||||
A64-OLinuXino link:
|
||||
https://www.olimex.com/Products/OLinuXino/A64/
|
||||
|
||||
Wiki link:
|
||||
https://openedev.amarulasolutions.com/display/ODWIKI/Olimex+A64-Olinuxino
|
||||
|
||||
This configuration uses U-Boot mainline and kernel mainline.
|
||||
|
||||
How to build
|
||||
============
|
||||
|
||||
$ make olimex_a64_olinuxino_defconfig
|
||||
$ make
|
||||
|
||||
Note: you will need access to the internet to download the required
|
||||
sources.
|
||||
|
||||
How to write the SD card
|
||||
========================
|
||||
|
||||
Once the build process is finished you will have an image called "sdcard.img"
|
||||
in the output/images/ directory.
|
||||
|
||||
Copy the bootable "sdcard.img" onto an SD card with "dd":
|
||||
|
||||
$ sudo dd if=output/images/sdcard.img of=/dev/sdX
|
||||
$ sudo sync
|
||||
|
||||
Insert the micro SDcard in your A64-OLinuXino and power it up. The console
|
||||
is on the serial line, 115200 8N1.
