Hmm, there is no file of the type you mentioned: $ ls /usr/lib/pkgconfig/wx* ls: cannot access /usr/lib/pkgconfig/wx*: No such file or directory A Google search for "wx pkg-config" appears to reveal that wxwidgets does not support pkg-config, or at least it didn't a few years ago. Lots of people will try "cabal install wx," right? So it seems like that's probably not the problem, but I'm not sure where the code that is generating the following output lives: Configuring wxcore-0.12.1.2... setup: Missing dependencies on foreign libraries: * Missing C libraries: wx_baseu-2.8, wx_baseu_net-2.8, wx_baseu_xml-2.8 I tried untarring ~/.cabal/packages/hackage.haskell.org/wxcore/0.12.1.2/wxcore-0.12.1.2.tar.gz and looking at Setup.hs to no avail. If I could see what test is failing, I could probably figure it out. On Thu, Nov 26, 2009 at 10:19 PM, Daniel Fischer wrote:

Greetings Haskellers,

Happy Thanksgiving! I'm using Ubuntu 9.10. I've performed the following steps:

# apt-get install ghc6

I then successfully did a local install of the Haskell platform in ~/mine/install

Now I am trying to get wxhaskell to install:

$ cabal install wx [snip] Configuring wxcore-0.12.1.2... setup: Missing dependencies on foreign libraries: * Missing C libraries: wx_baseu-2.8, wx_baseu_net-2.8, wx_baseu_xml-2.8 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: wx-0.12.1.2 depends on wxcore-0.12.1.2 which failed to install. wxcore-0.12.1.2 failed during the configure step. The exception was: exit: ExitFailure 1

$ ls /usr/lib/libwx* /usr/lib/libwx_baseu-2.8.so      /usr/lib/libwx_baseu_net-2.8.so.0.6.0 /usr/lib/libwx_baseu-2.8.so.0    /usr/lib/libwx_baseu_xml-2.8.so /usr/lib/libwx_baseu-2.8.so.0.6.0  /usr/lib/libwx_baseu_xml-2.8.so.0 /usr/lib/libwx_baseu_net-2.8.so    /usr/lib/libwx_baseu_xml-2.8.so.0.6.0 /usr/lib/libwx_baseu_net-2.8.so.0

It looks like the libraries are there to me! any ideas?

Perhaps cabal configure uses pkg-config to detect those libraries and you have no wx_***.pc in /usr/lib/pkgconfig ? That occasionally happens to me.

Ah. Is there a better GUI library to work with? Is cabal along with the Haskell Platform a good idea? Or is it better to just stick with libraries that install natively using APT on Ubuntu? I'm just trying to write a little GUI application (John Conway's Game of Life) to learn Haskell. Thanks, Josh On Fri, Nov 27, 2009 at 1:07 PM, Daniel Fischer wrote:

I think the Ubuntu 9.10 packages are up-to-date, so I'll try using gtk2hs with the Ubuntu packages next time I have some free time. Thanks for the help! Josh On Fri, Nov 27, 2009 at 4:18 PM, Daniel Fischer wrote:

I don't know which one is 'better' for what purposes, but gtk2hs is much used. It is unfortunately, as far as I know, not cabalised, so you'd have to manually install it.

Don't know if it's still true, but the debian packages used to lag far behind hackage, so that used to not be a serious option. If nowadays the debian-haskell packagers are up to speed, apt-get has advantages over cabal install.

This is now no longer true. I read the header "dialup.h" and replaced the "undeclared" macros wxEVT_DIALUP_(DIS)CONNECTED with the appropriate values in eljevent.cpp, then wxcore built and afterwards also wx. I haven't tested it, so it may be broken, but if it is, that shouldn't be the cause, I think.

The shared libraries are there, but did you check if the miscellaneous headers were there ? In other word did you install the libwx*-dev packages as invited to do by cabal in its error message ?
