Re: [wxhaskell-users] Windows 7 GetCommandLine call interference
I also notice that if I use the git repo:head for wxHaskell on Linux, I get a similar error + Usage as windows, but on the command line. The version of wxHaskell that cabal fetches does not have this problem. On windows, I took the repo:head because the released wxHaskell that cabal downloads had a compile failure for a ‘long long’ So perhaps there something that has changed in wxHaskell that causes a generic problem.

Re: [wxhaskell-users] installation problem on Win 8.1, WXCFG
Andrew, I just compiled on Win 7 64 bit. I’m not experienced with compiling wxWidgets, but this is what I did: Installed TDM GCC 64 bit. Change path to put it before the Haskell gcc Downloaded wxWidgets 3.0.2 tarball. Not the git head. It had some problems compiling. export WXWIN="C:\Users\…your-name...\Documents\wxWidgets-3.0.2" export WXCFG="gcc_dll\mswu" Run cmd.exe and cd to build\msw mingw32-make -j8 -f Makefile.gcc SHARED=1 UNICODE=1 BUILD=release VENDOR=cl CXXFLAGS="-fno-keep-inline-dllexport -std=gcc++11" MONOLITHIC=1 Note, gcc++11, not c++11 Search for the two dll files in lib and copy them to c:\Widows\System32 or wherever you want them Get the latest wxHaskell code, because the last release has this compile error: "C:\Program Files\Haskell Platform\2014.2.0.0\mingw\bin\gcc.exe" "-Isrc/include" "-IC:\SourceCode\wxWidgets\include" "-IC:\SourceCode\wxWidgets\lib\gcc_dll\mswu" "-DWXUSINGDLL" "-D_UNICODE" "-D__WXDEBUG__" "-D__WXMSW__" "-DHAVE_W32API_H" "-DwxcREFUSE_MEDIACTRL" "-DBUILD_DLL" "-c" "src\cpp\eljlistctrl.cpp" "-o" "dist\dist-sandbox-d11f86f1\build\src/cpp/eljlistctrl.o" src\cpp\eljlistctrl.cpp: In function 'int ListCmp(long int, long int, long int)': src\cpp\eljlistctrl.cpp:16:23: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] src\cpp\eljlistctrl.cpp:16:53: warning: cast to pointer from integer of different size [-Wint-to-pointer-cast] src\cpp\eljlistctrl.cpp: In function 'bool wxListCtrl_SortItems(wxListCtrl*, void*, void*)': src\cpp\eljlistctrl.cpp:478:41: error: cast from 'EiffelSort* {aka _EiffelSort*}' to 'long int' loses precision [-fpermissive] src\cpp\eljlistctrl.cpp:478:44: error: invalid conversion from 'int (*)(long int, long int, long int)' to 'wxListCtrlCompare {aka int (*)(long long int, long long int, long long int)}' [-fpermissive] C:\SourceCode\wxWidgets\include/wx/msw/listctrl.h:342:10: error: initializing argument 1 of 'bool wxListCtrl::SortItems(wxListCtrlCompare, wxIntPtr)' [-fpermissive] cabal.exe: Error: some packages failed to install: wxc-0.91.0.0 failed during the building phase.

Fix windows path so that the Haskell gcc comes first again Compile the wxHaskell app. Find the wxc.dll in the sandbox and copy to c:\Windows\System32 or wherever you want it And things work. Note my other e-mail about command line args. With the above, my linux wxHaskell app compiled and ran on Windows 7 64 bit. Like I said, not an expert on this. Just hacked to something that worked.

Another reason why the compilation failed, might be that the configuration file specifies a debug build, instead of a release build. You can build a 64 bit wxHaskell, even though there is a 32 in the name mingw32-make; take care that you build wxWidgets with the same bitness. To build wxWidgets as 64 bits DLLs, I changed some values in build\msw\config.gcc to: # Standard flags for CC CFLAGS ?= -m64 # Standard flags for C++ CXXFLAGS ?= -m64 # Standard preprocessor flags (common for CC and CXX) CPPFLAGS ?= -D_M_AMD64 Regards, Henk-Jan van Tuyl -- Folding@home What if you could share your unused computer power to help find a cure?

[wxhaskell-users] Is there a way to send a code to execute on main wx thread?
Hello, I am using wxHaskell to show a simple window with a button. A click on the button begins a task which takes a screenshot of the screen, does some computation on it and then simulates mouse clicks. Currently this task runs in the main wx thread, which makes the button unnecessarily unnresponsive for some time. Ideally I would like to be able to run this task in a separate thread and only send the GUI related code to execute on the main thread. I can not run GUI related code on a different thread, because wx, like most GUI libraries, is not thread safe. On wxPython documentation I read that this could be possible with events, however I could not find anything in wxHaskell which corresponds to creating new custom events and wx.postEvent method, which fires the event to the main thread. This method is described here: http://wiki.wxpython.org/Non-Blocking%20Gui#Communicating_with_the_main_thread . So my question is whether it is possible to do it in the way as described in the wiki above or do you have a different solution to my problem?
