ghc-5.02.2 is not a cygwin application, so it won't understand paths like /d/foo -- it will understand d:/foo and d:\foo though.
Internally, the compiler will canonicalise paths to 'platform-native' formats before passing them to external tools, which is why you see the slashes reversed. GHC could with benefit do some verification of -o paths, to avoid the cryptic msg you're seeing -- I'll add it to my ToDo list. hth --sigbjorn ----- Original Message ----- From: "Malcolm Wallace" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, March 05, 2002 02:54 Subject: filepath mangling under Windows? > With ghc-5.02.2 running from a Makefile in a cygwin shell under > Windows XP, the following behaviour occurs: > > ghc -package lang -package posix -c > -o /d/haskell/hmake-3.00/targets/ix86-CYGWIN_NT-5.1/obj/hmake/QSort.o > QSort.hs > Assembler messages: FATAL: Can't create > \d\haskell\hmake-3.00\targets\ix86-CYGWIN_NT-5.1\obj\hmake\QSort.o: > No such file or directory > > It looks like ghc has reversed the slashes in the filepath given > to the -o option, and this is the reason the assembler fails. > The directory certainly exists, but we suspect cygwin only understands > the forward-slash form not the backward-slash form. > > Is this a bug in ghc?
