macos - Haskell / cabal：可以链接到macos上的.so文件吗？

问题描述

在 Mac 上，我已经完成了brew install freetds，这给了我一个文件libtdsodbc.so。现在我尝试通过将路径放在我的.cabal中来链接到它extra-lib-dirs，但我得到了

* Missing (or bad) C library: tdsodbc
This problem can usually be solved by installing the system package that
provides this library (you may need the "-dev" version). If the library is
already installed but in a non-standard location then you can use the flags
--extra-include-dirs= and --extra-lib-dirs= to specify where it is.If the
library file does exist, it may contain errors that are caught by the C
compiler at the preprocessing stage. In this case you can re-run configure
with the verbosity flag -v3 to see the error messages.

这样做stack build --verbose向我展示了失败的命令是 cabal configure，所以我再次运行它并-v3附加，它告诉我：

为什么不能ld链接到 MH_BUNDLE？cabal 只能链接到dylibmac 上的 's，还是我需要一些特殊选项？

编辑：通过链接到.so链接到的dylib来解决。
