首先, 我这么写 extern "C" void func(){}; 代码爆红:(error: expected identifier or ‘(’ before string constant ) what the fuck!! 百度后是说c编译器不支持这种写法, 会报错, 虽然我知道我用的是c++编译器,然而决定还是改一下 #ifdef __cplusplus #define EXTERNC externc "C" #else #define E...
1、意思是：在 xxx 之前 应输入表达式。2、下面为C语言的错误大全及中文解释：1: Ambiguous operators need parentheses — 不明确的运算需要用括号括起 2: Ambiguous symbol xxx — 不明确的符号 3: Argument list syntax error — 参数表语法错误 4: Array bounds missing — 丢失数组界限符 5: ...

【C 语言中不支持extern "C" 声明,在.c 文件中包含了extern "C" 时会出现编译语法错误(error: expected identifier or ‘(’ before string constant )】 而在main.cpp中,C++是认识这个的,所以可以直接用extern "C" {}包起来。 在hello.h中改成我们最熟悉的这种形式,哈哈哈,make后就一切OK了 ...
