在Windows下编译gnu目标c时,objective-c-libgmp-10.dll丢失了

我该怎么做才能让它发挥作用？ (我在Windows 7 64位上)

几个月前我已经让它工作了,虽然我认为我当时使用Vista 32位.

    Nota:,if an error window opens complaining about libgmp-10.dll missing,then you used a bugged version of the MinGW installer
167 
    (some DLLs are not correctly installed). To fix the problem,just type the following commands:
168 
     cp /mingw/bin/libgmp-10.dll /mingw/libexec/gcc/mingw32/4.5.2
169 
     cp /mingw/bin/libmpc-2.dll /mingw/libexec/gcc/mingw32/4.5.2
170 
     cp /mingw/bin/libmpfr-1.dll /mingw/libexec/gcc/mingw32/4.5.2
171 
     cp /mingw/bin/libiconv-2.dll /mingw/mingw32/bin
172 
     cp /mingw/bin/libintl-8.dll /mingw/mingw32/bin

但我只在/ mingw / bin /中找到了libgmp-3.dll
