C++ 对‘inflate’的未定义引用

undefined reference to `inflate'

提问by SteveDeFacto

Trying to link against a static assimp library which I built with MinGW. Here are the errors I'm getting:

尝试链接到我用 MinGW 构建的静态 assimp 库。以下是我收到的错误：

Those are functions in the zlib library. Do you have zlib.h and the zlib library (.a or .lib) and the paths set correctly

这些是 zlib 库中的函数。您是否有 zlib.h 和 zlib 库（.a 或 .lib）以及正确设置的路径
