    <p>I am having some issues using HsLua as a library. Lua compiles just fine as a standalone. And this version runs on my Linux box without a problem. Here is the linking error I see.</p> <pre><code>GHCi, version 7.4.1: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done. Loading package integer-gmp ... linking ... done. Loading package base ... linking ... done. Prelude&gt; import Scripting.Lua as Lua Prelude Lua&gt; l &lt;- Lua.newstate Loading package hslua-0.3.4 ... linking ... &lt;interactive&gt;: C:\..\AppData\Roaming\cabal\hslua-0.3.4\ghc-7.4.1\HShslua-0.3.4.o: unknown symbol `___strtod' ghc.exe: unable to load package `hslua-0.3.4' Prelude Lua&gt; </code></pre> <p>I did some poking around the libraries and found the call for strtod and I think I may have been close but obviously not close enough.</p> <p><strong>EDIT</strong></p> <p>This may or may not help. I'll post the cabal file, I made a couple of changes such as adding the os(windows) portion.</p> <pre><code>Name: hslua Version: 0.3.4 ...

Makes me think that is barking up the wrong tree. </p> <p><strong>EDIT-2</strong></p> <p>Well I haven't been able to get this built yet on win32. A couple of other things I tried to do that didn't work for me just in case someone else runs into the same problem.</p> <p>I linked all of the built object files into a static archive and I got the same error as above. I also tried to use a build DLL and I got a different error but I'm not sure if it were progress forwards or backwards.</p> <pre><code>C:\..\hslua-0.3.4&gt;ghci liblua.dll -package hslua GHCi, version 7.4.1: http://www.haskell.org/ghc/ :? for help Loading package ghc-prim ... linking ... done.

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.
