Hi everybody, I've had some difficulty installing wxHaskell on Windows 7, but I eventually got there, so I thought I should report (and edit the wiki).
In a nutshell: the secret is to use wxPack (precompiled wxWidgets including MinGW Unicode version) [1] and avoid trying to build wxWidgets yourself. Credit goes to SkyTreeBird23 for suggesting wxPack in his guide [2]. (Say hello if you're reading this mailing list!) This is not a complete how-to. I'll edit the wiki when I have a spare moment. But I hope this list of pitfalls helps somebody in the meantime. My setup -------------------------------------------------- - VM running in Parallels 6 allocated 1 GiB of RAM - Windows 7 Professional - WxPack 2.8.12.01 - wxcore 0.12.1.7 - wx-config.exe Things I have tried - Mingw (32 bit) installer version 20110530 (have also tried 20110316) - TDM GCC 4.5.2 Documentation -------------------------------------------------- 1. wxHaskell on Haskell wiki (Building) http://haskell.org/haskellwiki/WxHaskell/Building 2. wxWidgets MingW page http://wiki.wxwidgets.org/Installing_WxWin_MinGW Issues I've run into ---------------------------------------------------------------------- 1. ld.exe: out of memory allocating N bytes Solution: use the TDM version of GCC, not the MinGW. See wxWidgets wiki page above; it might be some sort of MinGW bug. 2. ld returned 5 exit status Solution: clean your source tree (after hitting #1). Just typing mingw32-make -f makefile.gcc clean was apparently not enough, so I ended up unzipping a fresh one 3. wxHaskell builds fine, but when running any GUI app: The procedure entry point __gxx_personality_v0 could not be located in the dynamic link library libstdc++-6.dll Solution: (stumped - I think this has may have something to do with building Haskell stuff with the HP-built-in GCC and wxWidgets with the TDM GCC, but I don't really understand enough about libraries to say) At this point, I stumbled on SkyTreeBird's guide who informed me of the existence of 4. wxWidgets hasn't been found installed at 'C:\wxWidgets-2.8.12' The wxPack installer unfortunately does not include a dash by default in the path it offers you. I think it wants to put wxWidgets in something like 'C:\Source Code\wxWidgets2.8' I got rid of the 'Source Code', but did not notice the missing hyphen. 5. (Hello world) The program can't start because wxmsw28u_gcc.dll is missing from your computer Solution: make sure C:\wxWidgets-2.8.12\lib\gcc_dll (substitute your wxWidgets path accordingly) is in your PATH [1] http://wxpack.sourceforge.net/ [2] http://www.scribd.com/doc/38034374/20100923-WxHaskell-Setup -- Eric Kow <http://erickow.com>
