Re: [Haskell-beginners] gtk2hs [GIMP ToolKit]

Hi Patrick, 2011/2/5 Patrick Lynch

I reinstalled Gtk* but switched the folder from Program Files (x86) to Program Files...

I'm sorry, you misunderstood me. Please make sure you read my second last post about "Program Files" on Windows 7. I *think* it's no good idea to have both "Program Files" and "Program Files (x86)" folders. Type dir c:\ in the console. Then you see the *real* folders, unsugared. In Windows explorer or other dialogs, they are sugared, i.e. "Program Files (x86)" may appear as "Program Files". When you refer to them in Environment variables, I *guess* you have to use the *real* names again, like printed in the console. But I currently cannot verify this because at home I have only Win XP. But a little experiment should help you there. When I wrote "pkg-config.exe should be in C:\Program Files\Gtk+\bin" in my last post, I meant the bin folder of the Gtk+ installation, no matter where it is in your installation. Regards Tim

I changed all my environment variables to remove Program Files (x86)...

Unfortunately, it once again doesn't see the five original directories...see following:

* Missing C libraries: z, cairo * Missing C libraries: gobject-2.0, glib-2.0, intl

Got me...it seems like the cabal system should know where everything is going to be installed - then it should only have a dependency on the environment variables if it can't find its files in the default locations...

Do you think it would be worthwhile trying an installation using Program Files (x86) rather than Program Files [remember, on my PC , when doing the gtk installation it wants to do it in Program Files (x86)]

Good weekend

I hate to tell you this, but gtk* is being installed in Program Files (x86) and not in Program Files... I'll try it again...

The paths look ok from here. Please uninstall both your Gtk+ installations and reinstall just one. Then make sure your INCLUDE and PKG_CONFIG_PATH refer to it. It's possible you're referring to the 'bin' of one while trying to use the 'include' and 'pkgconfig' of the other.

Good afternoon,

In the course of doing this, I probably did the installation twice, meo culpa.

As fro the environment variables, they are [note: each directory is on a separate line]: echo %PATH% C:\Program Files (x86)\Haskell\bin; C:\Program Files (x86)\Haskell Platform\2010.2.0.0\lib\extralibs\bin; C:\Program Files (x86)\Haskell Platform\2010.2.0.0\bin; C:\Windows\system32; C:\Windows; C:\Windows\System32\Wbem; C:\Program Files (x86)\Common Files\Roxio Shared\DLLShared\; C:\Program Files (x86)\Common Files\Roxio Shared\10.0\DLLShared\; C:\Users\User\AppData\Roaming\cabal\bin; C:\Program Files\Gtk+\bin;C:\Users\User; C:\Program Files (x86)\Gtk+\bin; c:\Program Files (x86)\Gtk+\share\gettext echo %INCLUDE% C:\Program Files\Gtk+\include\libglade-2.0; c:\users\user\downloads\libxml2-2.2.7-1_win32\include; C:\Program Files\Gtk+\include; C:\Program Files (x86)\Gtk+\include echo %PKG_CONFIG% [presumably this should be PKG_CONFIG_PATH, since PKG_CONFIG is not used]: echo %PKG_CONFIG_PATH% C:\Program Files\Gtk+\lib\pkgconfig; C:\Program Files\Gtk+\lib\pkgconfig\include; c:\users\user\downloads\libxml2-2.2.7-1_win32\lib\pkgconfig echo %LIB% [added just for sake of completeness]: C:\Program Files\Gtk+\lib; C:\Program Files (x86)\Gtk+\lib

Why do you have Gtk+ in two folders? Did you somehow install it twice? Also what's in the following environment variable: PATH, INCLUDE, PKG_CONFIG

Good afternoon:

Step 1 ['cabal install gtk2hs-buildtools'] ran successfully.

This is what 'echo %lib%' gives: C:\Users\User>echo %lib% C:\Program Files\Gtk+\lib;C:\Program Files (x86)\Gtk+\lib

This is what pkg-config --modversion gtk+-2.0 gives: C:\Users\User>pkg-config --modversion gtk+-2.0 2.16.2

Thanks again

Hi Patrick,

2011/2/5 Patrick Lynch

This is what I did so far: 1. I followed your wiki 2. I opened Command window and entered the command: cabal install gtk 3. It returned the error messages: * Missing C libraries: z, cairo * Missing C libraries: gobject-2.0, glib-2.0, intl 4. I then ran the command: cabal install gtk --extra-include-dirs="c:/Program Files/Gtk+/include" --extra-lib-dirs="c:/Program Files/Gtk+/include" This returned the same error messages as indicated in step 3 above.

Step 1 should already include step 2, so I better ask if gtk2hs-buildtools installed successfully?

If the compiler misses some libraries, it will never help to add more include folders, because they only contain header files, not lib files. For missing include files, you get a different error message. For libraries, you have to set up the LIB environment variable properly. It must include the lib folder with Gtk+. Could you show us the result of

echo %LIB%

at the prompt? The ouput of

pkg-config --modversion gtk+-2.0

might indicate an error as well. By the way, the environment variables at the command prompt should the sum of those made globally and those made for the current user.

Good luck Tim
