If you&#39;re building something that has leftover *.o and *.hi files from a previous version of ghc, that might cause the problem.&nbsp; Try to rm *.o *.hi ?&nbsp; This seemed to work for me one time.<br><br>- Phil<br><br><div class="gmail_quote">

This morning I downloaded and installed ghc-6.8.2-powerpc-apple-darwin.tar.bz2.<br>I&#39;m now getting link errors when I use ghc. For example, the simple program<br><br> &nbsp;import qualified Data.IntSet as IntSet<br> &nbsp;main = print $ 
IntSet.empty<br><br>gives the errors:<br><br> &nbsp;/usr/bin/ld: Undefined symbols:<br> &nbsp;___stginit_containerszm0zi1zi0zi1_DataziIntSet_<br> &nbsp;_containerszm0zi1zi0zi1_DataziIntSet_empty_closure<br> &nbsp;_containerszm0zi1zi0zi1_DataziIntSet_zdf3_closure
<br><br>These symbols are defined in<br>/usr/local/lib/ghc-6.8.2/lib/containers-<a href="http://0.1.0.1/libHScontainers-0.1.0.1.a" target="_blank">0.1.0.1/libHScontainers-0.1.0.1.a</a>,<br>so apparently the linker is not finding this library.
<br><br>The same program does work in ghci, and in ghc-6.6 (which I was using<br>previously).<br><br>I&#39;ve searched the list archives, and I haven&#39;t found any mention of<br>this problem. Any help would be much appreciated!
