我试图在cabal沙箱中安装reactive-banana,wx,wxcore。运行cabal install --only-dependencies
时会出现以下错误消息:
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]

C:\wxWidgets-3.0.2\include/wx/msw/listctrl.h:342:10: error: initializing argument 1 of 'bool wxListCtrl::SortItems(wxListCtrlCompare, wxIntPtr)' [-fpermissive]
有什么问题以及如何解决这个问题?
答案 0 :(得分:0)
此文件中的代码似乎是错误的,即使在64位版本中也使用32位类型。除非在以后的版本中修复,否则唯一的解决方案是将其构建为32位,即使用32位Haskell安装。
