Question

I need glib for threadscope to work. But I am not able to install it using cabal. I tried cabal install glib but getting the following error. I even tried downloading the library and installing it locally but get the same error.

I am using Cygwin on Windows. I ran Cygwin setup to make sure I have the missing libraries. I was able to find glib, gobject but not gthread.

    Gtk2HsSetup.hs:25:2:
         warning: #warning Setup.hs is guessing the version of Cabal. If compilation
     of Setup.hs fails use -DCABAL_VERSION_MINOR=x for Cabal version 1.x.0 when buil
    ding (prefixed by --ghc-option= when using the 'cabal' command)
    [1 of 2] Compiling Gtk2HsSetup      ( Gtk2HsSetup.hs, dist\setup\Gtk2HsSetup.o )

    [2 of 2] Compiling Main             ( Setup.hs, dist\setup\Main.o )

    setup.exe: Missing dependencies on foreign libraries:
    * Missing C libraries: gobject-2.0, gthread-2.0, glib-2.0, intl, iconv
    This problem can usually be solved by installing the system packages that
    provide these libraries (you may need the "-dev" versions). If the libraries
    are already installed but in a non-standard location then you can use the
    flags --extra-include-dirs= and --extra-lib-dirs= to specify where they are.
    cabal: Error: some packages failed to install:
    glib-0.12.0 failed during the configure step. The exception was:
    ExitFailure 1

Some time ago I’ve written a small errata to the original wiki article on how to install Gtk2Hs. Here is the link http://progandprog.blogspot.com/2011/04/installing-gtk2hs-012-for-latest.html

I tried to describe all steps here, and hope it will help you.

All these steps are done with latest Gtk2Hs and Haskell platform installation. Without Cygwin and MinGW being installed.
