cppwinrt-clang

A sample C++/WinRT app using the clang compiler

Requirements

• Install LLVM >= 9.0.0 and add it to your path
• Install Windows 10 1903 SDK to C:\Program Files (x86)\Windows Kits\10\References\10.0.18362.0

A.) Build with Visual Studio, using clang

• Open cppwinrt-clang.sln and run the application

B.) Build from command line, using clang

Run build.bat

C.) Build from command line, using clang with MSVC frontend

Run build-with-clang-via-msvc-frontend.batd

Running build.bat will:

1.) Generate C++/WinRT header files

cppwinrt.exe @cppwinrt_plat.rsp

2.) Create output folder

if not exist build mkdir build

3.) Compile with Clang

set WINDOWS_SDK=C:\Program Files (x86)\Windows Kits\10\Lib\10.0.18362.0
clang -I "Generated Files" -D_WINDOWS -DUNICODE -D_UNICODE main.cpp -Xclang -std=c++17 \
-Xclang -Wno-delete-non-virtual-dtor -fcoroutines-ts -o build\cppwinrt-clang.exe \
-L "%WINDOWS_SDK%\um\x64" -Wl,kernel32.lib,user32.lib,windowsapp.lib

4.) Embed the manifest https://docs.microsoft.com/en-us/cpp/build/how-to-embed-a-manifest-inside-a-c-cpp-application?view=vs-2019

"C:\Program Files (x86)\Windows Kits\10\bin\10.0.18362.0\x64\mt.exe" -manifest cppwinrt.manifest \
-outputresource:build\cppwinrt-clang.exe;1

cppwinrt-clang.exe will appear in the build output folder
