Hi Claus. Moral support but little else below....
As noone has responded so far, I have to conclude that this is quite an infrequently used package..
- noone using ghc + win32 API? - noone using ghc + hgl on windows?
Although I feel the Win32 package is important I am finding it impossible to build GHC from CVS in order to debug my main project which, (unfortunately for your own interest in HGL), uses ObjectIO, so I felt that I was unable to offer anything coherent to you. I can't even get as far as the Win32 library while building GHC from scratch at the moment.
We suspect that Alastairs fixes may still leave some issues with concurrency / potentially blocking threads / ffi (at least in GHC's default configuration on windows), but we'd like to see just how far the improvements go, as the next stable release of GHC is imminent.
I suspect that the problems I had with profiling the ObjectIO library recently reported on the bugs list are also caused by thread issues, but I can't test this hypothesis due to the problems outlined above.
* Could anyone with cvs/fptools/makefile-expertise lend me a hand * if I try again to build only hslibs/win32 from cvs? Or is it * completely unreasonable to expect this to work?
The fresh greencard output seems to depend on parts of the ffi syntax that weren't supported in ghc-5.02.2, so I'd have to try with ghc-5.03.20020208 (the latest windows installer snapshot).
When I tried building CVS GHC with this package I got a compiler which would not work.
But if I try setting GHC_PKG_INPLACE today, there's absolutely no change! The setting in fptools/mk/build.mk seems to be ignored now?
Yes, I haven't found a way of getting around this problem myself other than hard wiring the compiler (possibly in target.mk from memory?)
Any helpful souls out there, who could lead me through the jungle of bewildering makefiles tomorrow (target date for feature completeness for the next release)?
Sorry not to be of more help.
If not, I'll just drop the issue (those who reported the problem earlier seem to have given up? and Simon Thompson, who last ran into it, does now get acceptable performance from Hugs/HGL for his app).
Lost, Claus
Even more lost, Mike Thomas.
