代码在windows gcc-6.3.0下无法编译通过

[AlexChingEraser]

您好~我直接从仓库拉代码下来无法编译通过：
os: win10 64bit
gcc: MinGW.org GCC-6.3.0-1

PS C:\Users\AlexC\Documents\GitHub\write-a-C-interpreter> gcc -m32 -o xc xc.c
xc.c: In function 'next':

                 if (current_id[Hash] == hash && !memcmp((char *)current_id[Name], last_pos, src - last_pos)) {

编译模板代码的时候会报open,read,close未定义先使用的错误：

PS C:\Users\AlexC\Documents\compiler> gcc -m32 .\compiler.c .\helloworld.c
.\compiler.c: In function 'main':
.\compiler.c:46:15: warning: implicit declaration of function 'open' [-Wimplicit-function-declaration]
     if ((fd = open(*argv, 0)) < 0) {
               ^~~~
.\compiler.c:56:14: warning: implicit declaration of function 'read' [-Wimplicit-function-declaration]
     if ((i = read(fd, src, poolsize-1)) <= 0) {
              ^~~~
.\compiler.c:61:5: warning: implicit declaration of function 'close' [-Wimplicit-function-declaration]
     close(fd);

在论坛上找到相似问题，但还是无法解决，如引入以下头文件：

#include <fcntl.h> // for open
#include <unistd.h> // for close

是我本地的gcc版本有问题吗？还是必须要在linux环境下运行？

@AlexChingEraser 一般 warning 错误应该不影响编译，有 error 错误吗？

[1jian10]

没有error，但是程序会退出，显示usage:[-s] [-d] file ...

[lotabout]

没有error，但是程序会退出，显示usage:[-s] [-d] file ...

是怎么运行的？显示 usage: .... 代表你需要传入要运行的 c 文件，例如：

./xc hello.c
./xc -s hello.c

./xc xc.c hello.c
./xc xc.c xc.c hello.c

这个在wimdows上就会这样，我在linux上跑就没问题了
