我正在尝试在Msys2中构建SpatiaLite。构建进展顺利，直到尝试编译示例。它会抛出错误，因为链接器找不到动态链接器 (dl) 库。这是我应该期望 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
这是编译器/链接器输出

C:\MinGW\msys\1.0\bin\sh autogen.sh
它输出
autogen.sh: line 4: readlink: command not found
autogen.sh: line 4: dirname: command not found
**Error**: Directory `' does not look like the top-level package directory
我不希望 readlink 可以与 Windows 一起使用，所以我直接跳过了
C:\MinGW\msys\1.0\bin\sh configure
但是，这也会引发错误
