This is my lunch break project to explore compiling of Windows GUI (SDL) binaries from within WSL Linux environment using Linux Clang.
This uses CMake toolchain file feature to setup Clang-cl for producing Windows based all-in-one binary with SDL library included. To produce such binary Linux Clang (running inside in WSL) depends on Windows SDK and MSVC standard library headers installed on Windows host. For this project I had Visual Studio 2022 Build Tools and Windows 10 SDK 10.0.19041.0 installed in standard locations in Program Files (x86).
CMake3.20 (Linux version in WSL)Clang15 (Linux version in WSL)ninja(Linux version in WSL, optional)- Microsoft Visual Studio 2022 Build Tools (on Windows)
- Windows 10 SDK ver. 10.0.19041.0 (on Windows)
To modify either version or path to Visual Studio 2022 or Windows 10 SDK edit
file ClangMSVC.toolchain.cmake.
This was the purpose of this experiment.
cmake -Bbuild/ -GNinja --toolchain ClangMSVC.toolchain.cmake
cmake --build build/cmake -Bbuild/ -GNinja
cmake --build build/cmake.exe -Bbuild/ -GNinja
cmake.exe --build build/Above commands should bootstrap build/ directory and clone and configure SDL2
from Github. Then it should build wslsdlexample[.exe] binary.
As you can see the only difference between native and cross-compile scenarios
is prsence of --toolchain file.
