    v13 v14  
    1 == Installing GenI == 
    2  
    3  1. I can't {{{cabal install wx}}}: 
    4   * '''Solution''': 2009-02-14: Try  
    5 {{{ 
    6 cabal install wx --configure-opt="--user --enable-split-objs --hcprof 
    7 }}} 
    8  1. Every time I try to {{{cabal install}}} GenI, it keeps trying to build wxcore (and fails!) 
    9   * This is a tricky one.  For some reason cabal-install keeps trying to re-install wx  
    10   * '''Workaround''': 2009-02-14 : install GenI by hand ({{{runhaskell Setup configure --user; runhaskell Setup build; runhaskell Setup install}}}) 
    11  1. I get this error when I try to do {{{runhaskell Setup configure}}}: 
    12 {{{ 
    13 GHCi runtime linker: fatal error: I found a duplicate definition for symbol 
    14    waitForProcess 
    15 whilst processing object file 
    16    /home/me/.cabal/lib/process-1.0.1.1/ghc-6.10.1/HSprocess-1.0.1.1.o 
    17 This could be caused by: 
    18    * Loading two different object files which export the same symbol 
    19    * Specifying the same object file twice on the GHCi command line 
    20    * An incorrect `package.conf' entry, causing some object to be 
    21      loaded twice. 
    22 GHCi cannot safely continue in this situation.  Exiting now.  Sorry. 
    23 }}} 
    24   * '''Workaround''': 2009-02-14: I don't know the proper solution to this yet, but I found that it helps to {{{ghc --make Setup}}} and then call {{{./Setup}}} instead of runhaskell Setup

    26 == Running GenI for the first time == 
    27  
    28  1. I get this error when I run GenI (wxHaskell 0.11 ; wxWidgets 2.8), and GenI refuses to load 
    29 {{{ 
    30 (process:11334): GLib-GObject-CRITICAL **: /build/buildd/glib2.0-2.18.2/gobject/gtype.c:2458: initialization assertion failed, use IA__g_type_init() prior to this function 
    31  
    32 (process:11334): GLib-CRITICAL **: g_once_init_leave: assertion `initialization_value != 0' failed 
    33  
    34 (process:11334): Gdk-CRITICAL **: gdk_cursor_new_for_display: assertion `GDK_IS_DISPLAY (display)' failed 
    35 }}} 
    36   * '''Solution''': 2009-02-14: upgrade to a later wxHaskell (the darcs version) - see http://www.haskell.org/haskellwiki/WxHaskell/Troubleshooting 
    37  1. I get this error when I try to run GenI: 
    38 {{{ 
    39 geni: error while loading shared libraries: libwxc-gtk2.8.8-0.11.1.so: cannot open shared object file: No such file or directory 
    40 }}} 
    41   * '''Solution''': 2009-02-14: add the wxhaskell lib directory to your LD_LIBRARY_PATH, for example in bash: 
    42 {{{ 
    43 export LD_LIBRARY_PATH=${LD_LIBRARY_PATH:+$LD_LIBRARY_PATH:}${HOME}/.cabal/lib/wxhaskell-0.11.1/lib 
    44 }}} 
    45  1. GenI segfaults 
    46   * Argh! Sounds like a potential wxHaskell bug.  Try {{{--no-gui}}} 
    47   * 2009-02-14: I have filed http://sourceforge.net/tracker2/?func=detail&aid=2599836&group_id=73133&atid=536845 
    48  1. I get this error why I try to run GenI: 
    49 {{{ 
    50 geni: relocation error: geni: symbol _ZTV13wxGraphicsPen, version WXU_2.8 not defined in file libwx_gtk2u_core-2.8.so.0 with link time reference 
    51 }}} 
    52   * '''Solution''' : 2009-10-12 this indicates that you're dynamically linking against a different version of wxWidgets than the one you compiled wxHaskell against.  Check your .bash_profile (or the equivalent .cshrc file) to make sure you don't have any stray LD_LIBRARY_PATH environment variables pointing to an older wxWidgets 
    53 == How to do cool things == 
    54  
    55 1. How do I use the paraphrase selection mechanism documented in ''A Symbolic Approach to Near-Deterministic Surface Realisation using Tree Adjoining Grammar''? 
    56  * At the time of this writing (2009-01-22), there is no documentation on this.  Sorry.  See ParaphraseSelection and ask Eric Kow for more details. 
    57 1. What's wrong with lexical items that have an empty semantics? 
    58  * Infinite loops, especially but not necessarily if the item is an auxiliary tree 
    59  * Difficulty constructing a polarity automaton - except maybe for pronouns if you enable the zero literal semantic items
