1)
I have 3 directories:
c:\temp\imports, c:\temp\objs and c:\temp\tst.
Current directory is c:\temp. Directory c:\temp\tst
contains 2 files: Main.hs and Ex.hs. Main.hs import
Ex.hs
I compile with
ghc tst\Main.hs -itst --make -odir objs -hidir imports
-o main.exe
ghc raise error:
FATAL: Can't create objs\tst\Main.o: No such file or
directory
I think that objs\tst\Main.o must be objs\Main.o
Ex.hs compiled to objs\Ex.o
2)
ghc-pkg with option -a and maybe with -r produces
package.conf.old. In the second when I use "ghc-pkg
-a"
it raises "Fail: already exists", because
package.conf.old already exists.
3)
When compile these examples with option --make, ghc
raises error:
Test.hs:9: Foo Int
./Test.hi-boot:8: Foo Int
file Test2.hs:
module Test2 where
import {-# SOURCE #-} Test
tst x = show x
fun = "??" ++ f (0 :: Int)
file Test:
module Test where
import Test2
class Foo a where
f :: a -> String
instance Foo Int where
f = tst
file Test.hi-boot:
__interface "Main" Test 1 502 where
__export Test Foo{f};
import PrelBase ! :: 1;
import PrelShow :: 1;
;
instance {Foo PrelBase.Int} = zdfFooInt ;
class Foo a where { f :: a -> PrelBase.String; };
zdfFooInt :: {Foo PrelBase.Int};
I found these bugs when I porting Clean ObjectIO to
ghc-5.02. Bug fixes allow me complete port.
