When I was doing mvn package for judger, something went wrong.

Did you install gcc and add it to PATH variable?

[yrregnehc]

I downloaded Mingw64 and put it in the front of the path variable like this:

C:\Program Files\mingw-w64\x86_64-7.1.0-posix-seh-rt_v5-rev0\mingw64\x86_64-w64-mingw32\bin;

I downloaded Dev-C++ though, and I'm not sure if it will affect the path.

By the way, what's the easiest way to install gcc on windows?

[hzxie]

Please open Command Prompt and type:

gcc -v

What 's the output?

I install gcc with MINGW.

[yrregnehc]

I didn't do these two steps: copy jawt_md.h .. copy jni_md.h .. what do they mean? Simply copy these two files to the parental directory?

[hzxie]

Yes.

[hzxie]

But I do think there's something wrong with your gcc and PATH variable.

[yrregnehc]

I think so, but I don't know how to install GCC effectively on Windows.

[hzxie]

So what's your output of gcc -v?

[yrregnehc]

[hzxie]

Nice.

Please open MINGW_HOME/bin, where MINGW_HOME represents the path where you install gcc. Rename or copy mingw32-make.exe to make.exe.

[yrregnehc]

Okay, let me see

[yrregnehc]

It works now! Thanks so much!
