msys2 / mingw 缺少动态链接器库

Question

我正在尝试构建 SpatiaLite in Msys2. The build goes well until it attempts to compile the examples. It throws an error because the linker cannot find the dynamic linker (dl) library。这是我应该 msys2/mingw 支持的东西吗？我是不是少了一个包裹？

我使用

构建 spatialite

./configure && make

这是compiler/linker输出

msys2 需要包 mingw-w64-dlfcn，它提供 libdl.a 和 libdl.dll.a
