The include/wx/msw/private.h header contains a violation of the C++
standards that MSVC tolerates but Clang/LLVM does not.
WinBase.h contains the definition:
#define INVALID_HANDLE_VALUE ((HANDLE)(LONG_PTR)-1)
Which wxWidgets uses in:
template <wxUIntPtr INVALID_VALUE =
(wxUIntPtr)INVALID_HANDLE_VALUE>
The (effective) reinterpret_cast-ing of INVALID_HANDLE_VALUE in
WinBase.h means that the define isn't actually usable as a constant
expression for the template parameter.
Clang has indicated they have no intention of adding an MSVC
compatibility workaround for this problem. See LLVM bug 12116:
https://bugs.llvm.org/show_bug.cgi?id=12116
Given this, rework the wxWidgets header to remove the default
template parameter value (it is not used anywhere).
With this change, it's possible to compile wxWidgets applications
using Clang/LLVM (5.0) under MSVC.
About
wxWidgets is a free and open source cross-platform C++ framework for writing advanced GUI applications using native controls.
wxWidgets allows you to write native-looking GUI applications for all the major desktop platforms and also helps with abstracting the differences in the non-GUI aspects between them. It is free for the use in both open source and commercial applications, comes with the full, easy to read and modify, source and extensive documentation and a collection of more than a hundred examples. You can learn more about wxWidgets at https://www.wxwidgets.org/ and read its documentation online at http://docs.wxwidgets.org/
Platforms
wxWidgets currently supports the following primary platforms:
- Windows XP, Vista, 7, 8 and 10 (32/64 bits).
- Most Unix variants using the GTK+ toolkit (version 2.6 or newer or 3.x).
- OS X (10.7 or newer) using Cocoa (32/64 bits).
Most popular C++ compilers are supported including but not limited to:
- Microsoft Visual C++ 2003 or later (up to 2017).
- g++ 3.4 or later, including MinGW/MinGW-64/TDM under Windows.
- Clang under OS X and Linux.
- Intel icc compiler.
- Oracle (ex-Sun) aCC.
Licence
wxWidgets licence is a modified version of LGPL explicitly allowing not distributing the sources of an application using the library even in the case of static linking.
