Hi!
Bryn is trying to compile C->Haskell with
GHC on Win32, but ran into some problems. Firstly,
configure says,
$ ./configure
loading cache ./config.cache
checking host system type... i686-pc-cygwin
checking target system type... i686-pc-cygwin
checking build system type... i686-pc-cygwin
checking for Cygwin environment... (cached) no
checking for gcc... (cached) gcc
[..]
So, it says no Cygwin, but identifies the system as
i686-pc-cygwin. AFAIK, GHC uses mingw32 these days, doesn't
it? How can this be reliably tested for? (To exclude
-package posix on that platform.)
Secondly, are there any issues with symlinks? I append a
sequence of commands that seems to indicate that GHC doesn't
find a file, because it is symlinked.
Any ideas?
Cheers,
Manuel
-=-
Administrator@BRK ~/hipar/build/ghc5/base/admin
$ file BaseVersion.hs
BaseVersion.hs: symbolic link to ../../../../base/admin/BaseVersion.hs
So, change it to an absolute:
Administrator@BRK ~/hipar/build/ghc5/base/admin
$ ln -s /home/hipar/base/admin/BaseVersion.hs BaseVersion.hs
Administrator@BRK ~/hipar/build/ghc5/base/admin
$ ls
BaseVersion.hs Common.hs Config.hs Makefile
Administrator@BRK ~/hipar/build/ghc5/base/admin
$ file BaseVersion.hs
BaseVersion.hs: symbolic link to /home/hipar/base/admin/BaseVersion.hs
The build fails the same way, copy the command line and restrict it to just
the file we changed, to be sure:
Administrator@BRK ~/hipar/build/ghc5/base
$ ghc -M -syslib lang -optdep-f -optdep.depend -iadmin -ierrors -igeneral
-igra
phs -istate -isyms -isyntax -isysdep admin/BaseVersion.hs
ghc.exe: file `admin/BaseVersion.hs' does not exist
