2、问题调查过程: (1)经过查看相关类似issue,得出stringop-truncation选项导致,由于当前vsftpd中编译选项存在"-Werror"选项,会将stringop-truncation的报错当做error退出。 (2)经过回退gcc代码,回退到12.30增加补丁之前的版本,vsftpd编译成功。 (3)应该于bf16-and-matrix-characteristic.patch补丁相关。 3、结论: gcc确...
近些年伴随着苹果生态的蓬勃发展,越来越多的用户开始尝试接触Mac电脑。然而很多人上手Mac后会发现,它的使用逻辑与Windows存在很多不同,而且随着使用时间的增加,一些奇奇怪怪的文件也会占据有限的磁盘空间,进而影响使用。
GCC支持在编译的时候使用-std选项来选择编译语言的标准。程序本身也是在发展的,不断变化的。以 C 语言...
