Is anyone successfully using hmatrix-0.16.0.4 on OSX 10.9?
I get the following error:

ghc: unable to load package `hmatrix-0.16.0.4'
I installed using brew install gsl && cabal install hmatrix.
My ghc version is 7.6.3.
I suspect it should be built with gcc (instead of clang) -- how can I change this?
(GitHub ticket)
I fixed the issue by installing ghc 7.8. It's unfortunate that homebrew's "haskell-platform" is so out of date.

I’m trying to build a project in a cabal sandbox that depends on happstack-server, but this package fails to build. Here is the content of .cabal-sandbox/logs/happstack-server-7.4.6.1.log:

ByteCodeLink.lookupCE
During interactive linking, GHCi couldn't find the following symbol:
templatezmhaskell_LanguageziHaskellziTHziSyntax_zdfMonadQzuzdczgzgze_closure
This may be due to you not asking GHCi to load extra object files,
archives or DLLs needed by your current session. Restart GHCi, specifying
the missing library using the -L/path/to/object/dir and -lmissinglibname
flags, or simply by naming the relevant files on the GHCi command line.
Alternatively, this link failure might indicate a bug in GHCi.
If you suspect the latter, please send a bug report to:
glasgow-haskell-bugs#haskell.org
How can I fix this?
▶ ghc --version
The Glorious Glasgow Haskell Compilation System, version 7.8.4
▶ cabal --version
cabal-install version 1.18.1.0
using version 1.18.1.5 of the Cabal library
The problem was due to an older version of template-haskell installed by my OS package manager. This version was taken into account even though I work in a sandbox. I solved the issue by using cabal install --shadow-installed-packages.
So basically i fire up the gchi import the graphics library and then go and do this.

All this stuff happens, but no image is shown? Do i have to do some sort of main function call to display or how would i go about actually seeing a picture. Thanks for the advice.
Make sure you have the gnuplot binary installed, and not only the Haskell gnuplot package from hackage. The latter doesn't really check whether you have the necessary binary installed. Depending on your platform, it simply invokes a shell command or uses a pipe and doesn't look for the return type, therefore you don't even get an error.
You can check whether you have gnuplot installed via
$ gnuplot --version
If this doesn't give you a version, you either have yet to install gnuplot, or gnuplot isn't in your path.
I try to use the Graphalyze library, installed by the standard way cabal install graphalyze. When I import any modules from this package, I face with a trouble.

If I try again without reloading, I see only one string, but on differ library!:
Loading package bktrees-0.3.1 ... linking ... ghc: unable to load package `bktrees-0.3.1'
What is the problem?
I use WinGHCi 1.0.6 and ghc version 7.4.2, in ghci i have the same problem.
Upd: runghc results `HSregex-pcre-builtin-0.94.4.7.8.31.o: unknown symbol __imp__pcre _compile'
I installed my first Haskell package with cabal:
$ cabal install regex-pcre
Could someone post a simple example using pcre regexes so I can figure out what I am supposed to import?
Okay, I figured it out. The module you need is Text.Regex.PCRE. For POSIX regexes, it's Text.Regex.Posix. Here is an example:

The page: (http://en.wikibooks.org/wiki/Haskell/GUI) describes that to run wx code, one can install wx and then one must "register wxHaskell with GHC" - but I think the binary installer of wxHaskell (http://wxhaskell.sourceforge.net/download.html) does that automatically?
I installed wx-config, and then wxPack, and wxHaskell. and then did cabal install of wx and wxcore. I am running some wx demos from Leksah, which seem mostly good - but they had some weird errors (I found an alleged solution to that: "wxhaskell-labels-cant-display-full-text"), but I wanted to try some things just from GHCi.
I try to run their simple demos, and the the errors:

Please report this as a GHC bug: http://www.haskell.org/ghc/reportabug
It appears to be a known problem with the combination of wxHaskell, GHCi, and Windows. From http://www.haskell.org/haskellwiki/WxHaskell/Quick_start
On Windows 7, ghci will complain "can't load .so/.DLL for: std c++ ...". But ghc --make Hello.hs; Hello.exe on the command line works well.
So, you can compile your code. You just can't run it through the interpreter.
