# WINE + clang-cl build of pure Win32/Win64 TinyUSDZ library
|
|
|
|
TinyUSDZ can be compiled with clang-cl + MSVC SDK.
|
|
And can run it on top of WINE. Pure Windows C/C++ app/library build on Linux!
|
|
|
|
## MSVC SDK license
|
|
|
|
https://devblogs.microsoft.com/cppblog/updates-to-visual-studio-build-tools-license-for-c-and-cpp-open-source-projects/
|
|
|
|
MSVC SDK(Visual Studio Build Tools, Microsoft C++ Build Tools) EULA has been relaxed to use it(grab a copy) for OSS build without Visual Studio license.
|
|
|
|
Note that Windows SDK does not require VS license.
|
|
|
|
## Setup
|
|
|
|
Download llvm prebuilt for your HOST architecure(e.g. Ubuntu x86_64 if you are using x64 Linux()
|
|
Note that ubuntu prebuit is provided up to 14.0.0
|
|
|
|
https://github.com/llvm/llvm-project/releases/tag/llvmorg-14.0.0
|
|
|
|
Install Ninja build tool.
|
|
|
|
### WSL
|
|
|
|
On WSL, easy way is instll VSBT in Windows side.
|
|
|
|
https://visualstudio.microsoft.com/visual-cpp-build-tools/
|
|
|
|
You can also use `msvc-wine` in the following.
|
|
|
|
### Linux(Ubuntu)
|
|
|
|
https://github.com/mstorsjo/msvc-wine
|
|
|
|
We recommend to use msvc-wine effort. It automates downloading MSVC SDK and Windows SDK and unpacking it.
|
|
|
|
Note that recent msvc-wine makes foldername/filename lowercase.
|
|
|
|
## Cross compile TinyUSDZ with clang-cl
|
|
|
|
Plase see `scripts/bootstrap-clang-cl-wsl.sh`
|
|
|
|
```
|
|
cd build-clang-cl-wsl
|
|
cmake -G Ninja -DCMAKE_TOOLCHAIN_FILE="cmake/clang-cl-msvc-wsl.cmake" \
|
|
-DHOST_ARCH=x64 \
|
|
-DLLVM_NATIVE_TOOLCHAIN="/mnt/d/local/clang+llvm-14.0.0-x86_64-linux-gnu-ubuntu-18.04/" \
|
|
-DMSVC_BASE:FILEPATH="/mnt/d/VC/Tools/MSVC/14.26.28801/" \
|
|
-DWINSDK_BASE="/mnt/d/winsdk/10/" \
|
|
-DWINSDK_VER="10.0.18362.0" \
|
|
..
|
|
```
|
|
|
|
Edit `MSVC_BASE` and `WINSDK_BASE`(You can use Windows path if you are cross-compiling on WSL), and `WINSDK_VER` to fit your MSVC SDK, Windows SDK.
|
|
|
|
Note that recent msvc-wine makes foldername/filename lowercase. You may need to edit some foldername/filename(e.g. `Windows.h -> windows.h` in `cmake/clang-cl-msvc-wsl.cmake`
|
|
|
|
## Run on Wine.
|
|
|
|
`vcruntime**.dll` and some MSVC/ucrt dlls are required in the PATH.
|
|
You can set it through `WINEPATH`
|
|
|
|
```
|
|
$ WINEPATH="%PATH%;C:\path\to\dlls" wine64 ./usda_parser.exe
|
|
```
|
|
|
|
EoL.
