What version of cabal-install are you using?<span></span><br><br>On Friday, January 24, 2014, Jan Stolarek &lt;<a href="mailto:jan.stolarek@p.lodz.pl">jan.stolarek@p.lodz.pl</a>&gt; wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">
A couple of days ago I realized that I can&#39;t compile latest HEAD on my Debian Squeeze laptop.<br>
Some -fPIC issues prevented compilation of integer-gmp library. I reported this as #8666. Today I<br>
got another PIC-related error on a different machine with openSUSE 11.4:<br>
<br>
/usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../x86_64-suse-linux/bin/ld:<br>
dist/build/compile/compile-tmp/Data/Singletons/Core.dyn_o: re<br>
location R_X86_64_PC32 against undefined symbol `DataziSingletonsziTypes_Proved_con_info&#39; can not<br>
be used when making a shared object; recompile with -fPIC<br>
/usr/lib64/gcc/x86_64-suse-linux/4.5/../../../../x86_64-suse-linux/bin/ld: final link failed: Bad<br>
value<br>
collect2: ld returned 1 exit status<br>
<br>
This happened with HEAD when I tried to compile testsuite configured via cabal file (on 7.6.3 all<br>
is fine):<br>
<br>
test-suite compile<br>
  type:               exitcode-stdio-1.0<br>
  ghc-options:        -Wall -O0 -main-is Test.Main<br>
  default-language:   Haskell2010<br>
  main-is:            Test/Main.hs<br>
<br>
Before I fil in another bug report could someone offer me a straightforward explanation of what is<br>
this whole -fPIC thing? Why does it break my code? Is this a known issue? Is there any kind of<br>
workaround for this?<br>
<br>
