I encountered this while trying to compile truecrypt-6.1 from bug 245322. The build process there calls g++ with -DBOOL=int, but still I get errors like this "error: ‘BOOL’ does not name a type". I traced this to wx/db.h which defines BOOL, includes some other headers, and then unconditionally undefines it again. The inclusion path is the following: <wx/wx.h> -> "wx/window.h" -> "wx/colour.h" -> "wx/variant.h" -> "wx/db.h" Bug 210024 worked around this for previous truecrypt releases, and including that workaround again would be easy. On the other hand, I consider it bad behaviour for a header file to undefine any macros, especially such common ones. Therefore I'd prefer wxGTK to address this issue. I'll attach a patch.
Created attachment 171002 [details, diff] Use and keep already defined BOOL This patch only defines and undefines BOOL if it hasn't already been defined. If it already is defined, it is assumed to be compatible with int, or that the application won't use that part of the wxGTK interface. No further checks made.
makes sense to me. http://trac.wxwidgets.org/ticket/10167
Patch applied to wx sources, will be in 2.8.10, thanks.
Thanks for the quick response. Fixed in wxGTK-2.8.9.1-r2 and -r3.
