那么该选项可以与-Werror =和-Wno-error =一起使用 ,如上所述。 (可以使用-fno-diagnostics-show-option标志禁用警告消息中的选项打印。) 请注意,指定-Werror = foo会自动隐含-W foo 。 但是, -Wno-error = foo并不意味着什么。 -Wfatal-errors 此选项会导致编译器在发生第一个错误时中止编译,而不是尝试...
This is however a minor compiler bug, since decimal integer constants use the the quoted list in 6.4.4.1: int then long then long long. Therefore this applies: "If all of the types in the list for the constant are signed, the extended integer type shall be signed....

Although an effort has been made to warn about all such cases, there are probably some cases that are not warned about, even though G++ is generating incompatible code. There may also be cases where warnings are emitted even though the code that is generated will be compatible. You should...

[提示]以下选项是在完整的阅读了ld-2.18文档之后挑选出来的选项。 http://blog.chinaunix.net/u1/41220/showart_354602.html 有2.14版本的中文手册。 -s 删除可执行程序中的所有符号表和所有重定位信息。其结果与运行命令 strip 所达到的效果相同,这个选项是比较安全的。
