There is an asumption for these instructions that you have a normal development environment set up (Visual Studio, CMake, Git, etc), alongside LLVM 18.1.8 on an ARM64 machine. Cross-compilation has not been validated.

All code blocks are run from a “ARM64 Native Tools Command Prompt for VS 2022” window.

As part of these examples, the libraries are built statically (as it made running ctest to verify them easier) - it is possible (and encouraged in many cases) to build them dynamically.

There is a considerable performance boost (up to 46% observed in blender) when using clang-cl instead of MSVC - consider using that instead of MSVC via -DCMAKE_C_COMPILER="clang-cl" and -DCMAKE_CXX_COMPILER="clang-cl"

“ctest” is broken for ptex on Windows, due to a mismatch of CRLF and LF with the test data - manually checking the difference reveals the tests pass

ctest does not run when compiled with the above instructions - it requires more dependencies, and is considered beyond the scope of this page.

However - upon running it though with the additional requirements, all tests pass.

Only OneTBB as specified in the 2025 standard works. TBB 2020.3 as defined in older versions does not work without a large patch - an example can be seen in Blender (this has since been removed, as Blender now follows the 2025 spec): https://projects.blender.org/blender/blender/src/commit/d5823ad8959abe611fd4dac8125ed0921dbf7276/build_files/build_environment/patches/tbb.diff

Note that things such as TBBmalloc do not work with the Blender patch, and would require further engineering effort to enable

Line 5 might need to be run twice, as the first attempt may end in an unknown failure - it should still build though
