GHC --make should also look for .hi, not only for .hs
Currently, ghc --make
will only consider .hs source files from the include path.
Example (assuming Library
can't be resolved from the package database):
A.hs
module A where
import B
import Library
B.hs
module B where
Compiling these files with ghc --make -Idir A.hs B.hs
will succeed only if GHC finds a Library.hs
file.
In a thread on glasgow-haskell-users, Simon proposed relaxing this constraint; namely: In --make
mode, when encountering an import X
, GHC will try the following in order:
- resolve the import from a package
- search the include path for
X.hs
orX.lhs
- search the include path for
X.hi
It already does 1 and 2, and this proposal would add 3.
