Wt

Hello,

We build Wt with VS2017 on Windows. But it failed with error C2338: tuple index out of bounds [D:\Wt\build_x86\src\wt.vcxproj];error C2338:static_assert(_Always_false<integral_constant<size_t, _Index>>,[D:\Wt\build_x86\src\wt.vcxproj];error C2338:(compiling source file D:\Wt\src\src\Wt\Json\Parser.C) [D:\Wt\build_x86\src\wt.vcxproj]. This issue is caused by master revision 0b458aa. Could you please help take a look at this? Thanks!

Note:

Wt requires boost. You can get boost 32bits and 64bits from following address and Change the install path:

32bits: c:\boost_1_64_0\x86

64bits: c:\boost_1_64_0\x64

Boost: https://sourceforge.net/projects/boost/files/boost-binaries/1.64.0/

Repro steps:

1. Open VS2017 x86 Native tools command tool
   
2. git clone https://github.com/emweb/wt d:\Wt\src

6. msbuild /m /p:Configuration=Release;Platform=Win32 ALL_BUILD.vcxproj /t:Rebuild
