Hi,
I assume CreateDebuggedProcess is defined in bindings.lib? You need to also add extra-libraries: bindings
Also keep in mind that C++ has a different name mangling than C, so if your function is in a class you'll need to use the proper name for it.
nm -g bindings.lib would show the actual name.

Hi,
I made a lib from a cpp project with one function: BOOL Foo(LPCSTR bar)
In the stack project I added the .lib file's folder to the extra-lib-dirs/extra-include-dirs and then, in main:
{-# LANGUAGE ForeignFunctionInterface #-}
module Main where
import System.Win32.Types
import Foreign.C.String
main :: IO ()
main = do
withCString "bar" c_Foo
putStrLn "success"
foreign import ccall "bindings.lib Foo"
c_Foo :: LPCSTR -> IO BOOL
When building I get the following error
Building all executables for `tape' once. After a successful build of all of them, only specified executables will be rebuilt.

What am I doing wrong?
