gcc或者ld链接时，默认链接的库有哪些，

Question

或者说怎么查看默认连接的库

Answer 1

使用ldd可以查看

$ ldd a.out

比如我用win下的msys2给你演示一下

hang@ZhouHang MSYS ~
$ cat hello.c
#include <stdio.h>

int main(){
    printf("Hello world!");
    return 0;
}


hang@ZhouHang MSYS ~
$ gcc hello.c

hang@ZhouHang MSYS ~
$ ./a
Hello world!

hang@ZhouHang MSYS ~
$ ldd a
        ntdll.dll => /c/Windows/SYSTEM32/ntdll.dll (0x7ffe971c0000)
        KERNEL32.DLL => /c/Windows/system32/KERNEL32.DLL (0x7ffe94840000)
        KERNELBASE.dll => /c/Windows/system32/KERNELBASE.dll (0x7ffe94610000)
        msvcrt.dll => /c/Windows/system32/msvcrt.dll (0x7ffe96b90000)
