问题描述

在学习正点原子的驱动开发指南过程中，在编译Linux内核时出现以下报错，内核文件为：linux-imx-rel_imx_4.1.15_2.1.0_ga。

./mx6ull_alientek_emmc.sh文件内容如下

#!/bin/sh
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- distclean
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- imx_v7_defconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig
make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- all -j16

报错信息如下：

解决方案

先后尝试过将gcc-12版本重装为gcc-9版本，运行后出现更多错误。以及在/scripts/dtc/dtc-lexer.lex.c文件中对YYLTYPE yylloc; + extern 变为extern YYLTYPE yylloc; 无效。

最后通过以下办法解决问题：

重新下载了arm-linux-gnueabihf-gcc

gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf.tar

通过百度网盘分享的文件：gcc-linaro-4.9.4-2017.01-x86_64_arm...

步骤如下：

将文件拷贝到Ubuntu根目录下的tools文件中

sudo mkdir /usr/local/arm

sudo cp gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf.tar.xz /usr/local/arm/ -f

sudo tar -vxf gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf.tar.xz

sudo vi /etc/profile

export PATH=$PATH:/usr/local/arm/gcc-linaro-4.9.4-2017.01-x86_64_arm-linux-gnueabihf/bin

sudo apt-get install lsb-core lib32stdc++6

sudo reboot

arm-linux-gnueabihf-gcc -v
