Hi Henk,
According to http://yhc06.blogspot.com/2006/09/yhccore-api-available.html this option should exist, but it is not listed with command yhc -?
The option got renamed to -core in the last week, as part of the ongoing Core cleanup effort.
(By the way, the help info uses "yhcc" instead of "yhc".)
How did you obtain Yhc? From what date? I've just checked and yhcc is no longer anywhere in the source tree, so shouldn't be displayed that way.
Another problem is, that I cannot get the compiler compiled at my Windows XP system (I am using GHC 6.4, so I can use wxHaskell, and Darcs 1.0.3)
After running Makefile.bat all I get the messages:
The makefile.bat is no longer the correct way to compile on Windows, now all systems use the Scons make system - http://haskell.org/haskellwiki/Yhc/Building. You might also want to check that you are using the haskell.org repo, not the york.ac.uk one. Sorry about this, quite a few things have changed quite recently and none of the documentation is quite up to date yet!
Can you help me get things working?
Hopefully with the new information, you should be able to build Yhc. Unfortunately Dr Haskell won't work with Yhc any more - the changes to the Core language will have broken it. However, I plan to fix this up, and given that there is demand will hopefully fix Dr Haskell on Monday. Thanks Neil
