    <p>hi im not sure what im doing and basically i tried to get ghc and haskell-platform on to my mac via homebrew however for reasons that i don't understand, ghc doesn't work hence neither does haskell-platform</p> <p>according to brew doctor:</p> <pre><code>Warning: Unbrewed .pc files were found in /usr/local/lib/pkgconfig. If you didn't put them there on purpose they could cause problems when building Homebrew formulae, and may need to be deleted. Unexpected .pc files: /usr/local/lib/pkgconfig/fuse.pc its-fatbass:~ jellynom$ brew doctor Warning: Unbrewed .pc files were found in /usr/local/lib/pkgconfig.

It cannot compile a simple program (see config.log for the details). If you installed ghc from a generic binary tarball then it is worth checking that you have the 'gmp' C library and header files installed. (On Debian-based systems this package is called libgmp3-dev.) READ THIS: https://github.com/mxcl/homebrew/wiki/troubleshooting These open issues may also help: https://github.com/mxcl/homebrew/issues/20956 </code></pre> <p>i don't know how to check for the gmp c library and header files and the link they recommended is completely over my head too; something about hscolor missing.</p> <p>Does this mean i have other things i should have installed prior to installing ghc??? (i have nothing else installed via homebrew other than ghc and haskell-platform) if so, what should i have installed??</p>

    1. COYou can install GMP using `brew install gmp`. You can then try to reinstall GHC. Also if you can find and post the contents of `config.log` it should help to understand what is the problem.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
