How to compile Qt 5.7.1 or 5.8.0 using clang msvc 2015?

Akito_Kami

I am attempting to compile Qt from source using the clang msvc 2015 mkspecs.
I have run
"call "C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\bin\amd64\vcvars64.bat"a" to set the microsoft c++ compiler and then run

configure -platform win32-clang-msvc2015 -shared -opensource -nomake examples -nomake tests -release -qt-libjpeg -qt-libpng -qt-zlib.

Currently I get an error returning

libcmt.lib(chkstk.obj) : fatal error LNK1112: module machine type 'X86' conflicts with target machine type 'x64'
NMAKE : fatal error U1077: '"C:\Program Files (x86)\Microsoft Visual Studio 14.0\VC\BIN\link.EXE"' : return code '0x458'
Stop.
Building qmake failed, return code 2

EDIT: I am fixed the error above but clang is now looking for .pch files.

error: unable to read PCH file .pch\release\Qt5Core_pch.pch: 'no such file or directory'
fatal error: PCH file '.pch\release\Qt5Core_pch.pch' not found
2 errors generated.

Hi,

Did you re-run configure from a clean state ?
