When I run my program, I get a stack overflow message (current stacksize is
8388608 bytes) and the advice to use +RTS -Ksize -RTS
The Haskell code creates a Windows dll, so no command line. That's why I
want to change the stack size at compile time.
I tried ghc -shared -O2 -o -with-rtsopts="-H128m -K64m" TBGlas.dll
TBGlasDll.hs
Ghc tells that it links with "-H128m -K64m". When I run the program I still
get a message overflow with again the same (?) 8388608 stack size. I also
changed the stacksize of the calling program, but no luck (same message).
I wonder whether ghc ignores the -with-rtsopts parameter?
Probably the problem is caused by not enough strictness, but still I want te
make sure that it is not the stacksize (it is a big program).

I think the default RTS options are only settable in a compile that
produces an executable; otherwise there would have to be a chunk of code
that retrieved all the rtsopts from every Haskell-compiled DLL and somehow
reconciled any conflicts between them. Also note that if the main program
is in C, you don't get -with-rtsopts processing at all; see
http://www.haskell.org/ghc/docs/latest/html/users_guide/ffi-ghc.html#using-own-mainfor
how you set RTS options in this case. (See at "To use +RTS flags with
hs_init()".)
In this particular case you may be better off just using the %GHCRTS%
environment variable.

I understand the problem. I?ve set the GHCRTS environment variable and when I
run the program I get : <unknown>: Most RTS options are disabled. Link with
?rtsopts to enable them.
Then I added rtsopts to the command line: ghc -shared -rtsopts -O2 -o
TBGlas.dll TBGlasDll.hs
and I get the same errormessage again: Most RTS options are?? What is the
problem?
I?am using GHC version 7.4.2 in Windows.
Greetings,
Kees

Exact same issue. Those cannot be per DLL, they apply to the final program
(what would it mean for only some DLLs to allow RTS options? There's only
one runtime!); and you'd probably have to use the same mechanism I pointed
at before if you're invoking hs_main() from C instead of using a Haskell
main function.
