Hey Bulat, I tried removing the "import System.Win32", but unfortunately it only got me so far: | Examples$ ghc -i.. -O2 -funbox-strict-fields --make wc.hs -o wc | Chasing modules from: wc.hs | [ 1 of 16] Compiling System.FD ( ../System/FD.hs, ../System/FD.o ) | | /tmp/ghc9376_0.hc:6:16: io.h: No such file or directory | /tmp/ghc9376_0.hc: In function `SystemziFD_zdwccall_entry': | | /tmp/ghc9376_0.hc:1670:0: | warning: implicit declaration of function `_eof' | /tmp/ghc9376_0.hc: In function `SystemziFD_zdwccall1_entry': | | /tmp/ghc9376_0.hc:1951:0: | warning: implicit declaration of function `filelength' | /tmp/ghc9376_0.hc: In function `SystemziFD_zdwccall2_entry': | | /tmp/ghc9376_0.hc:2055:0: | warning: implicit declaration of function `tell' | [abort] I also downloaded the new release archive, just to be sure. but it doesn't contain a file "io.h" either. Is that a system header? The problem seems to be _eof.
btw, my "wc" has about the same speed as yours :)
I expected nothing less. All your code I've seen so far has been exceptionally clever. I'm quite curious to try it out. Peter

Is that a system header? yes, in mingw :) i attached updated FD.hs. but if filelength/tell cannot be found through HsBase.h, i don't know what to do. at least, System.Posix.Internals does the same: #include "ghcconfig.h" #include "HsBaseConfig.h" foreign import ccall unsafe "HsBase.h read" c_read :: CInt -> Ptr CChar -> CSize -> IO CSsize foreign import ccall unsafe "HsBase.h write" c_write :: CInt -> Ptr CChar -> CSize -> IO CSsize it is possible that devil is in the including of those two additional files. try to add it. otherwise, we should wait until Simon be up :) -- Best regards, Bulat mailto:bulatz@HotPOP.com
