Hi,
I have the following strange situation. I am running GHC(i)
5 on Solaris.
I have the following files:
primtk.c
PrimTk.hs
Yahu.hs
Where
* "primtk.c" defines some C functions,
* "PrimTk.hs" contains the "foreign import" declarations
of these functions, and
* "Yahu.hs" is a Main module that uses "PrimTk.hs".
When I compile everything in the following way:
> gcc -c primtk.c -o primtk.o
> ghc primtk.o --make Yahu.hs
The resulting executable works fine!
However, when I try to do the same thing in GHCi:
> gcc -c primtk.c -o primtk.o
> ghci primtk.o Yahu.hs
...
Everything loads as expected (!), I can even run the
program, but unfortunately, while running my program, the
string constants (data part) in primtk.c/primtk.o get
overwritten by other functions.
My question is: is this a bug in the dynamic linking of
static object files in GHCi?
If so, I'd be happy to send the source files, (though there
are rather many of them.)
If I am not supposed to do it in this way, please tell me
how I am supposed to do it. I tried the following:
> gcc -c primtk.c -fPIC -shared -o primtk.so
> ghci primtk.so Yahu.hs
...
But then, GHCi complains about "primtk.so", it does not
recognize it as a dynamic object file. (Which it strange,
because there is an error message that identifies ".so"
files as valid arguments to GHCi...)
