JCGO的使用（java->C）

请问有哪位大神用过这个http://www.ivmaisoft.com/jcgo/download.htm，实现java转换为c，我在下载完所有要求文件后，说明文档进行到：
“4. Try to convert "Hello world" sample to Windows binary (unoptimized):

• create your "projects" folders (e.g., "C:MyJcgoProjects") and change

1. current directory to it;

• type:
  C:JCGOjcgo.exe -sourcepath $~examplessimple Hello @$~stdpaths.in

or, alternatively:
java -jar C:JCGOjcgo.jar -sourcepath $~examplessimple Hello @$~stdpaths.in

• invoke the MinGW C compiler (GCC):

1. -IC:JCGOinclude -IC:JCGOincludeboehmgc -IC:JCGOnative -DJCGO_FFDATA -o hello jcgo_OutMain.c C:JCGOlibsx86mingwlibgc.a

• or invoke Visual Studio C/C++ compiler:

1. -IC:JCGOinclude -IC:JCGOincludeboehmgc -IC:JCGOnative -DJCGO_INTNN -DJCGO_FFDATA -DJCGO_WIN32 -D_CRT_SECURE_NO_DEPRECATE -D_CRT_NONSTDC_NO_DEPRECATE jcgo_OutMain.c C:JCGOlibsx86msvcgc.lib /link /out:hello.exe

• run "hello.exe" file.”
  不知道如何进行下去了！求解答
