I am trying to draw a simple pixel with gtk/haskell. This is the code, but
I get an error.
GHC 6.12.3? with the most recent gtk library.
Error:
# ghc --make SimpleCells.hs

Hi everyone,
I'm having Cabal problems. Any help would really be appreciated.
When I try:
"cabal install soegtk"
or
"cabal install gtk"
or
"cabal install glib"
I get the error (abridged):
"
Cannot find gtk2hsC2hs
Please install `gtk2hs-buildtools` first and check that the install
directory is in your PATH (e.g. HOME/.cabal/bin).
[...]
gio-0.12.0 depends on glib-0.12.0 which failed to install.
glib-0.12.0 failed during the configure step. The exception was:
exit: ExitFailure 1
[...]
"
But:
gtk2hsC2hs and gtk2hs-buildtools ARE where they're supposed to be
(gtk2hsC2hs is in ~/.cabal/bin, and gtk2hs-buildtools is in
~/.cabal/share).
A possibly related issue is that when I run "cabal update" it tells
me my Cabal isn't the newest version. I successfully run "cabal
install cabal-install", then do "cabal update" and get the same
message again.
As a side question, is there a good resource about Cabal in greater
detail than a how-to? I'm looking for, say, what ARE the executables
in .cabal/bin? How do they relate to packages loaded in ghci?
Thanks for your time!
Tom

If you can't find a function, try searching on hayoo (at hackage.haskell.org).

Hi Tom.

The most likely explanation for your problems seems to be that while
you have the buildtools installed, you haven't actually added
$HOME/.cabal/bin to your search path, so it isn't found by cabal. This
might also hold for the new version of cabal-install you installed,
which installs a "cabal" binary to $HOME/.cabal/bin. But if you don't
have that in your search path, and have another "cabal" binary
installed in, say /usr/bin, then you'll still run the old version and
get the message about the newer version again.
Cheers,
Andres

A common mistake would be to add it in the form
export PATH="~/.cabal/bin:$PATH"
Many (most, I think) shells don't do tilde expansion in quoted strings, so
you'd have a literal '~' in your PATH. That's no problem if it's passed to
a shell, but other programmes usually don't do expansion for such strings.
If that's the case here, possible fixes are
- spelling it out
- using $HOME instead of ~
- not quoting

Also if the other cabal is in a place before $HOME/.cabal/bin in the PATH.
