highcanfly/llvm4msvc-x86 repository overview

⁠LLVM for MSVC

⁠Why

I have a Kubernetes cluster running aarch64 linux workers. I wanted to compile some apps on this cluster.
Mingw(64) is a fantastic tool but… The main idea was to use the current Windows SDK and the MSVC runtime like you do with Visual Studio. I found a fantastic tool https://github.com/Jake-Shadle/xwin⁠ made by Jake Shadle. His tool can download the CRT and the SDK directly from Microsoft servers. And thanks to clang/llvm and its target x86_64-pc-windows-msvc , building Windows x86_64 apps on linux aarch64 is possible…

In /usr/share/msvc/test you'll find a minimal Windows application.
With /usr/share/msvc/test/test.sh you can test a full compilation and executable generation.

⁠Compile with script

test.sh contains:

#!/bin/bash
$CL /I include /c src/test.c
$CL /I include /c src/MainWindow.c
$CL /I include /c src/AboutDialog.c

$LINK /subsystem:WINDOWS \
    user32.lib kernel32.lib comctl32.lib \
    test.obj MainWindow.obj AboutDialog.obj \
    /out:test.exe

⁠Disclaimer

I build this for my own use, it corresponds to my need, if you need to adapt it to your needs feel free to fork and adapt…
