#3857: gchi compiles but gch fails
------------------------+---------------------------------------------------
Reporter: dstr | Owner:
Type: bug | Status: new
Priority: normal | Component: Compiler
Version: 6.12.1 | Keywords:
Os: MacOS X | Testcase:
Architecture: x86 | Failure: GHC rejects valid program
------------------------+---------------------------------------------------
The following module loads into ghci but gch reports an error
module Temp where {
data Ftype = Numa Integer | Str [Char] ;
instance Show Ftype where
show (Str s) = s;
show (Numa n) = show n
}
gch error ====
Undefined symbols:
"_ZCMain_main_closure", referenced from:
_ZCMain_main_closure$non_lazy_ptr in libHSrts.a(Main.o)
"___stginit_ZCMain", referenced from:
___stginit_ZCMain$non_lazy_ptr in libHSrts.a(Main.o)
ld: symbol(s) not found
collect2: ld returned 1 exit status
And in gchi any function (ReadFtype) placed at the end of the module
gives error:
Onlyghci.hs:9:0: parse error on input `readFtype'
This same function placed before the instance command compiles.
Not sure if this is relevant but I am using Mac OS X Version 10.6
