缺省情况下是"-mno-thumb-interwork",因为指定了"-mthumb-interwork"产生的代码稍微大一些; -Wno-write-strings 会忽略掉C++ char* 转const char*的警告,这样并不会很安全; -Wno-trigraphs 关闭ANSI C的三字母词编译出现的错误;在ANSI C标准中,定义了9个三字母词(trigraph),三字母词就是几个字符的序列,合起...

一种方法是在gcc编译时,将它禁掉。-Wno-write-strings 如:yangshifu@ubuntu:~/Documents/sipApp_tkj$ g++ *.cpp -shared -fpic -Wno-write-strings -o sip.so 一种方法是在C++源代码中将它禁掉,#pragma GCC diagnostic ignored "-Wwrite-strings",只对某个文件生效 还有一种就是将const用const char*来保...

-fwritable-strings Store string constants in the writable data segment and don't uniquize them. This is for compatibility with old programs which assume they can write into string constants. Writing into string constants is a very bad idea; ``constants'' should be constant. This option is...
当请求无法识别的警告选项时(例如-Wunknown-warning ),GCC将发出诊断,指出该选项未被识别。 但是,如果使用-Wno- form,行为会稍有不同:除非正在生成其他诊断,否则不会生成-Wno-unknown-warning诊断。 这允许在旧编译器中使用新的-Wno-选项,但如果出现问题,编译器会警告存在无法识别的选项。
