What this is

I'm trying to get ntoskrnl.exe, hal.dll, bootvid.dll, ntdll.dll, and kdcom.dll to build with Clang, in the hope of seeing them work with the MSVC binaries in a normal build.

Currently, it hangs during boot.

win2k3_llvm.mp4

Instructions

You need Clang, LLVM, and CMake.

To compile things, this should work:

# LLVM build
tools\generate-clang.bat

# MSVC build
tools\generate-msvc.bat

cmake --build cmake-build-debug

To install the binaries, mount your install and do tools\copybins <drive letter>. It backs up the original files.

You can also go to minkernel/llvmtests and run compile.bat, then run testload <system32 path> to make sure the imports all resolve.

To do

• make libcntpr.lib compile with Clang
• figure out the hang on SYSTEM32\acpitabl.dat in NTLDR
• make shell scripts to do what batch files do
• write a program to convert simpler sources files to CMake?
• add Clang to original build system?
