How to ignore 'comparison between signed and unsigned integer expressions'?

Question

任何人都可以告诉我，为了使gcc忽略“有符号和无符号整数表达式之间的比较”警告消息，我必须使用哪个标志。

Answer 1

gcc -Wno-sign-compare

但是你应该真的修正它无论如何警告你的比较。

Answer 2

Here's what worked for me, using the gcc compiler in Code::Blocks. In the compiler settings, click the "Compiler Settings" tab, then choose "Other Compiler Options. Type in -Wno-sign-compare The warning -Wsign-compare can be negated by adding "-Wno" as a prefix. In fact warnings can be ignored by adding -Wno- to the warning code.
