Got it working with that fix - although I couldn't get the nhc98 -C step to work to compile the fixed .hs file (it complained about not finding Platform.hi in any of several locations, even after a full successful build there is still no Platform.hi anywhere - should there be?) so I just hand-modified the (encoded) string constant in RunAndReadStdout.hc.) So now I'm free to play with nhc98, thanks! I have another question though: on the "Building/Installing nhc98" page it says that if you build using the C compiler only the resulting compiler is slower. Why? I would have thought the hc files were directly from nhc (or ghc?) in the first place (and if from ghc then wouldn't the resulting compiler be faster than an nhc-bootstrapped compiler)? Anyway, now that I have built from C sources should I bootstrap through the resulting nhc98? Plus a small correction for the "Installing nhc98 under Windows" page: you also need cygwin's 'bc' tool which is not installed by default. -- Dave ----- Original Message ----- From: "Malcolm Wallace" To: "David Bakin" Cc: Sent: Thursday, April 10, 2003 2:03 AM Subject: Re: [nhc-users] Problem installing nhc98 1.16 using bootstrap-from-C method

I'm having trouble building nhc98 using bootstrap-from-C - the following shows the error I'm getting. It is actually executing in hmake3.config

I/O error: action : openFile ReadMode on file: /cygdrive/c/TEMP\hmakeconfig.tmp gave : ENOENT (No such file or directory)

I believe the problem here is the mixture of directory separators. When compiled by ghc the mix doesn't matter, but it does matter in a pure C-under-cygwin build, which likes to pretend to be Unix as much as possible.

In src/hmake/RunAndReadStdout.hs, try changing

tmpfile root = ... if windows then (tmp++"\\"++root++".tmp") to then (tmp++"/"++root++".tmp")

Then, because you are bootstrapping via C, you will need to re-generate the .hc file from this source before continuing with the build:

( cd src/hmake && ../../script/nhc98 -C RunAndReadStdout.hs ) make

I don't recall using 'bc' anywhere in the build scripts - can you let me know the location where you needed it please?
