错误编译coreutils-错误：函数可能是属性'const'的候选项[-Werror = suggest-attribute = const]

Question

我尝试在Ubuntu 18.4上编译coreutils。这是我到目前为止所做的：

sudo apt install bison gperf make textinfo

git clone git://git.sv.gnu.org/coreutils

cd coreutils

./bootstrap

./configure

make

这将导致错误提示：

lib/acl-internal.c: In function 'free_permission_context':
lib/acl-internal.c:479:1: error: function might be candidate for attribute 'const' [-Werror=suggest-attribute=const]
 free_permission_context (struct permission_context *ctx)

Answer 1

添加编译器标志

make CFLAGS='-Wno-error=suggest-attribute=const'

This post列出了一些其他选项：
我建议使用：
 -Wno-error=suggest-attribute=pure
 -Wno-error=suggest-attribute=const
 -Wno-error=suggest-attribute=noreturn
 -Wno-error=suggest-attribute=format
 -Wno-error=suggest-attribute=cold
 -Wno-error=suggest-attribute=malloc
