我想测试snappy库，但在编译我的项目时我有2个错误：

1> main.obj：错误LNK2019：未解析的外部符号“bool __cdecl snappy :: Uncompress（char const *，unsigned int，class std :: basic_string，class std :: allocator> *）”（？uncompress @ snappy @@ YA_NPBDIPAV函数_main中引用了？$ basic_string @ DU？$ char_traits @ D @ std @@ V？$ allocator @ D @ 2 @@ std @@@ Z）

1> main.obj：错误LNK2019：未解析的外部符号“unsigned int __cdecl snappy :: Compress（char const *，unsigned int，class std :: basic_string，class std :: allocator> *）”（？压缩@snappy @@ YAIPBDIPAV？$ basic_string @ DU？$ char_traits @ D @ std @@ V？$ allocator @ D @ 2 @@ std @@@ Z）在函数_main中引用

致命错误LNK1120：2个未解决的外部因素

我在项目属性中添加了lib和snappy32.lib的目录 .
