hi andre,
i just noticed you did a make distclean which of course
already wipes the config.cache, so the suggestion i sent in
as ible_snover was a duddo. oops. sorry
i just had another idea... but doh! no, i just thought for a second
that you may have needed to remove some files in your
ghc directory, but no, config.status, config.log and ghc.spec
in your ghc build directory are probably removed by make distclean
and even if they arent, i just checked and they are certainly updated
anyway when you re-run configure. So i have no idea, sorry. The
problem you are having sounds really, really really weird. Good luck
with the newer cygwin.
So since i dont have any other suggestions re your problem
ill just give you ppl some feedback on how i found the
whole ghc/HOpenGl make and install process, before i
forget the minor problems which i did have.
1) the ghc 5.02.3 source distribution didnt come with happy,
so i went and got it via CVS, and that fixed that.
2) the HOpenGL distributed with the ghc 5.02.3 source would
not compile. After compiling and installing the ghc 5.02.3 compiler
(with the 4.08 compiler booted up from .hc files), i re-ran configure
to use the ghc 5.02.3 compiler and also added the --enable-opengl
and --with-glut-api=4 switches and tried to get HOpenGL
compiled. But it failed, spitting the dummy as follows:

3) no luck there, so i just downloaded the HOpenGL 1.2 source
tarball, and the latest greencard tarball, compiled greencard and then
had another go at compiling HOpenGL. And success ! all the examples
compiled successfully too.
4) the only other thing that bothered me a bit was when i went to test
the whole thing by compiling BezMesh.hs
it just wasnt happening, as ghc was unable to locate GLUT as follows:
jss: /home/jss/stuff/src/haskell/opengl/BezMesh > ghc --make BezMesh.hs
ghc-5.02.3: chasing modules from: BezMesh.hs
ghc-5.02.3: can't find module `GLUT'
I did a simple ghc -v and was rewarded with a list of the packages ghc
was able to find, the last of which was:
----------
Package
{name = "HOpenGL",
import_dirs =
["/usr/local/ghc5.02.3/lib/ghc-5.02.3/imports/HOpenGL"],
source_dirs = [],
library_dirs = ["/usr/local/ghc5.02.3/lib/ghc-5.02.3"],
hs_libraries = ["HOpenGL"],
extra_libraries = [],
include_dirs = [],
c_includes = ["GL/glu.h"],
package_deps = ["lang"],
extra_ghc_opts = [],
extra_cc_opts = ["-I/usr/X11R6/include"],
extra_ld_opts =
["-lglut",
"-lGLU",
"-lGL",
"-lSM",
"-lICE",
"-L/usr/X11R6/lib",
"-lX11",
"-lXext",
"-lXmu",
"-lXt",
"-lXi",
"-lm"]}
---------------
this had me pulling my hair out for a good 15 minutes or so. I couldnt
believe i was so close, and yet still no donut. It didnt seem to make
sense that my ghc was able to find the HOpenGL package, and
yet not the GLUT. I was boggling and virtually frothing at the mouth
in frustration as the BezMesh.hs was first importing GL, which was
apparently OK, and then importing GLUT, which was not OK.
I was especially horrified by this because ghc --help gives this:
-------
To compile and link a complete Haskell program, run the compiler like
so:
ghc-5.02.3 --make Main
where the module Main is in a file named Main.hs (or Main.lhs) in the
current directory. The other modules in the program will be located
and compiled automatically, and the linked program will be placed in
the file `a.out' (or `Main.exe' on Windows).
-----------
Then I found this, in the HOpenGL dist. :
---------
jss: /home/jss/stuff/src/haskell/ghc/HOpenGL-1.02 > less NEWS
HOpenGL-1.02 is (again) mainly a compatibility release:
* Added support for 3D textures: texImage3D, texSubImage3D,
copyTexSubImage3D.
* Added a "make install" target to add a HOpenGL package to GHC. This makes
using HOpenGL much easier: A simple
ghc -package HOpenGL --make MyCoolApp.hs
is enough for most applications.
...
---------
that fixed the problem, ie ghc -package HOpenGL --make BezMesh.hs
succeeded.
I still dont know why the -package HOpenGL is necessary, but hey, its no
big deal, i will probably work that out soon enough...
All in all the install on linux went relatively painlessly, considering what
a huge and fearsome Beast the GHC is, and even HOpenGL aint
exactly small either.
kudos to all you GHC and HOpenGL development ppl. Amazing job.
ill shutup now,
john
