    Hi,<br>
    <br>
    I compared&nbsp; libraries/base/aclocal.m4 of the HEAD and 6.12 branch
    and found the difference:<br>
    <br>
    &lt; [AS_VAR_PUSHDEF([ac_Search], [ac_cv_search_$3])dnl<br>
    ---<br>
    &gt; [AS_VAR_PUSHDEF([ac_Search], [ac_cv_search_$1])dnl<br>
    <br>
    This was changed by patch:<br>
    <br>
    Thu Aug 19 22:48:58 CEST 2010&nbsp; Ross Paterson
    <a class="moz-txt-link-rfc2396E" href="mailto:ross@soi.city.ac.uk">&lt;ross@soi.city.ac.uk&gt;</a><br>
    &nbsp; * fix cache variable name used by FP_SEARCH_LIBS_PROTO<br>
    <br>
    I applied the patch to 6.12 what solved the problem.<br>
    <br>
    But you won&#8217;t even come to that point (compiling whole ghc and not
    only base) without the patch for ticket #4252 which is missing in
    6.12. I reported this already with ticket #4402

            Hi,<br>
            <br>
            I'm getting a build failure when I try to compile ghc-6.12

            ghc-cabal: Missing dependency on a foreign library:<br>
            * Missing C library: iconv<br>
            This problem can usually be solved by installing the system
            package that<br>
            provides this library (you may need the "-dev" version). If
            the library is<br>
            already installed but in a non-standard location then you
            can use the flags<br>
            --extra-include-dirs= and --extra-lib-dirs= to specify where
            it is.<br>

            I'm using a ubuntu 10.10-64 bit system with libc-bin and
            libc-dev-bin<br>
            installed. I don't think the problem is a missing iconv
            library. Maybe<br>
            the problem is in the generated configure script by the new
            autoconf<br>
            version (autoconf version is 2.67).<br>

          <br>
          I haven't encountered this problem, but I'm not using Ubuntu
          10.10 yet. &nbsp;Please report the bug on the Trac so we don't
          forget about it.<br>
