Can't get ghci to run
 

Hi
I am trying to run the Haskell ghci interpreter through Terminal but I get this error:


/usr/local/lib/ghc-6.10.4/ghc: error while loading shared libraries: libtinfo.so.5: cannot open shared object file: No such file or directory

I have installed ncurses but still get this problem

Can anyone help? I need this for a university assignment.

Thanks

What distro are you using ?

Mandrake (and redhat and probably others) compile ncurses without the
"--with-termlib" option. The "--with-termlib" option splits ncurses into
two: libncurses and libtinfo. It's not "wrong" to do it one way or the
other, but applications compiled against it need to match.

In other words, grab a source rpm from somewhere and try rebuilding on
your machine it
from http://shoe.bocks.com/nlug/2003-Jul/3221.html
but the key thing here is how did you install ncurses( depends on your distro) and how did you install Haskell ghci

If you had used your package manager to install Haskell, this wouldn't have happened.

I am using Scientific Linux.

I did try compiling ncurses with --with-termlib

I typed ./configure --with-termlib
then make
then make install

but this did not work.

What exactly am I meant to do?

Install Haskell using your package manager, not by trying to compile from source. A package manager would sort this all out for you automatically.

Hi
Sorry for the simple questions but how do I know what my package manager is? Does it install rpm´s?

I don't happen to know what Scientific Linux uses but I suspect it it "yum". So do this:

And if anything is missing after that, do this:

And choose additional packages.

Hi
I ran those commands but it said that not package was found. It doesn´t matter though because I downloaded a ghc source that did not require that libtinfo.so.5 file so now it works.

Thanks very much for you help
