一、copy_file_range
./../misc/create_inode.c:395:18: error: conflicting types for 'copy_file_range'
static errcode_t copy_file_range(ext2_filsys fs, int fd, ext2_file_t e2_file,
修改文件：./out/sun8iw11p1/linux/common/buildroot/build/host-e2fsprogs-1.43.3/misc/create_inode.c
注释掉：#inlucde <unistd.h>
./out/sun8iw11p1/linux/common/buildroot/build/e2fsprogs-1.43.3/misc/create_inode.c
二、write
问题：pipe.cpp:86:29: error: invalid conversion from 'char' to 'const void*' [-fpermissive]
::write(_fd_write, ' ', 1);
修改调用为：:write(_fd_write, “ ”, 1)
三、update_mbr failed
问题： 执行./build.sh pack时提示的问题
unable to open file rootfs_nor.fex dl file rootfs_nor.fex size too large
update_for_part_info -1 update mbr file fail
ERROR: update_mbr failed
方法一：安装make的3.81版本 ./build.sh distclean后重新编译
方法二：在网上查的，试了没有成功
根据出错信息：dl file rootfs.fex size too large。判断是rootfs.fex分区尺寸小了，改大就可以了！至于改多大合适，根据实际情况来确定了。（全志也没有明确给出尺寸的规定！实践中一般倍数放大，具体可以根据您所使用的FLASH的大小来灵活设置）
本例相差不大，直接改为2倍就可以了！
dl_file_size = 17920 sector
part_size = 13568 sector
W:perf1_r6_tinav2.1 argetallwinnersitar-perf1configssys_partition_nor.fex
[partition]
name = rootfs
;size = 13568
size = 27136
downloadfile = "rootfs.fex"
四、arm-linux-gnueabi-gcc
问题：export PATH=$PATH:/home/wang/work/lichee/brandy/gcc-linaro/bin/
/bin/sh: arm-linux-gnueabi-gcc: command not found
scripts/Makefile.build:308: recipe for target 'scripts/mod/empty.o' failed
make[2]: *** [scripts/mod/empty.o] Error 127
五、intltool
Your intltool is too old. You need intltool 0.35.0 or later. 最后拷贝系统的/usr/bin/intltool-update到构建目录，解决问题。
./out/sun8iw11p1/linux/common/buildroot/build/host-intltool-0.51.0/intltool-update
./out/sun8iw11p1/linux/common/buildroot/host/usr/bin/intltool-update
六、automake
问题：The error is with automake and perl v5.26.
In perl v5.22, using a literal { in a regular expression was deprecated, and will emit a warning if it isn't escaped: {. In v5.26, this won't just warn, it'll cause a syntax error.
A temporary work around is to edit automake file (buildroot/output/host/usr/bin/automake- and modify):
=================================================
goto line :3936 and change
解决方法：替换3936行的：
$text =~ s/${([^ =:+{}]+)}/substitute_ac_subst_variables_worker ($1)/ge;
