Haskell compile DLL without copy-past ghc/include folder
To compile a Haskell DLL without directly copying the GHC include
folder, you can specify the necessary include paths using the -I
flag in the GHC command. Here's an example of how you can compile a Haskell DLL without relying on the copied GHC include
folder:
Open a command prompt or terminal window.
Navigate to the directory containing your Haskell source file (
.hs
) and the necessary dependencies.Use the GHC command with the
-I
flag to specify the include paths:bashghc -shared -o YourDLL.dll YourModule.hs -I/path/to/include1 -I/path/to/include2
Replace
YourDLL.dll
with the desired name for your DLL andYourModule.hs
with the name of your Haskell source file.Modify
/path/to/include1
and/path/to/include2
to the actual paths where the required header files are located. These include paths should contain the necessary headers for any external libraries or dependencies your Haskell code relies on.By specifying the include paths explicitly, you don't need to copy the entire GHC
include
folder.If you have additional dependencies, include them in the command using the
-l
and-L
flags. For example, to link against a library calledYourLibrary
, you can use:bashghc -shared -o YourDLL.dll YourModule.hs -I/path/to/include1 -L/path/to/library -lYourLibrary
Replace
/path/to/library
with the actual path to the directory containing the library file (YourLibrary.lib
orlibYourLibrary.a
).The GHC compiler will generate the DLL file (
YourDLL.dll
) in the current directory.
By specifying the include paths and necessary dependencies explicitly, you can compile a Haskell DLL without relying on the copied GHC include
folder. Make sure to provide the correct paths for the include files and libraries required by your Haskell code.
