这是 C:\Ruby193\lib\ruby\gems\1.9.1\gems\thin-1.6.3\ext\thin_parser 中的 mkmf 文件的样子喜欢:

Here's what the mkmf file in C:\Ruby193\lib\ruby\gems\1.9.1\gems\thin-1.6.3\ext\thin_parser looks like:

"gcc -o conftest -IC:/Ruby193/include/ruby-1.9.1/i386-mingw32 -IC:/Ruby193/include/ruby-1.9.1/ruby/backward -IC:/Ruby193/include/ruby-1.9.1 -I. -DFD_SETSIZE=2048  -DFD_SETSIZE=2048  -O3 -fno-omit-frame-pointer -g -Wall -Wextra -Wno-unused-parameter -Wno-parentheses -Wno-long-long -Wno-missing-field-initializers -Wpointer-arith -Wwrite-strings -Wdeclaration-after-statement -Wimplicit-function-declaration conftest.c  -L. -LC:/Ruby193/lib -L.   -march=i486   -lmsvcrt-ruby191  -lshell32 -lws2_32 -limagehlp -lshlwapi  "
checked program was:
/* begin */
1: #include "ruby.h"
2: 
3: #include <winsock2.h>
4: #include <windows.h>
5: int main(int argc, char **argv)
6: {
7:   return 0;
8: }
/* end */

我使用的是 Windows 7.

I'm using Windows 7.

为什么我会收到错误消息?有一行说明无法创建 Makefile..."，但这是否相关?

Why am I getting the error? There's a line stating "could not create Makefile...", but is that relevant?

推荐答案

这对我有用:
